  2. Patricia Miqueline Gomes Santos. Consumo de frutos exóticos na dieta de um grupo de macaco-prego-de-crista, Sapajus robustus (Primates, Cebidae) na Reserva Natural Vale.. Waldney Pereira Martins, UNIMONTES, Setembro 2016.
    Abstract Exotic species are those that occur outside of its range historically known as a result of a process of accidental or intentional movement via human assistance. Due to the high consumption of exotic fruits by group Sapajus robustus Martins study target (2010), the author suggested that the exotic fruit would be acting as a substitute in the primate diet in relation to native foods at certain times of the year. Thus, the present study intended to test the existence of a pattern in the availability of exotic fruits over the years in the area of the Nature Reserve Valle and relate their availability for consumption by the same capuchin monkey crested. For data collection were used phenological data fruiting four exotic plants and 29 native contained in S. robustus diet in NRV. Analyzing every month, every year (2001-2010), can be seen that the exotic plants have always had a greater fruitfulness than native. Looking at the fruiting of exotic plants consumed by S. robustus, using the time series analysis, it can be noted that the following fruiting plants monthly distinct patterns between species over ten years analyzed (p <0.01). This difference fruiting rate of exotic higher than native should be the fact that exotic, are those that have a greater commercial appeal, namely naturally produce more fruit rich in nutrients and thus more attractive to the animals. It can be inferred that the group of S. robustus in NRV, probably feeding on exotic fruits because they are used to find these fruits always available and near their foraging area or be a local tradition of them. Analyzing the feeding behavior of the group, from March to July, the consumption of exotic is much lower than the other months of the year. This pattern of consumption coincides with the pattern of mango fruit that in the similar period, no fruit production. It can be inferred that the sleeve would be the preferred fruit for consumption of exotic in the group's diet, since the consumption of exotic is higher in periods of greater availability sleeve. The results of this study despite the fact that it is based on the feeding behavior of only one group of S. robustus, demonstrates the need to assess the importance of exotic fruits in the diet of primates.

  3. Maria Ingra Oliveira Martins. Atividade antineoplásica de princípios ativos obtidos a partir do extrato da casca do fruto do pequizeiro (Caryocar brasiliense Camb.). Geraldo Aclécio Melo, UNIMONTES, Agosto 2016.
    Abstract The cancer affects about 200 types of cells and is characterized by loss of cellular function and absence of differentiation, as well as uncontrolled proliferation. Studies are conducted to discover new drugs and treatment forms of this disease. Plant species are potential sources of new anticancer drugs, as well as suppliers of precursors of new chemotherapeutics. From this perspective, the objective was to fractionate and evaluate the potential use of pequizeiro fruit peel extract as a source of active ingredients with antineoplastic activity against tongue squamous cell carcinoma cell lines (SCC-9). After fractionation two fractions yielded from pequi peel extract (butanolic fraction and residual fraction) were tested in vitro using the test of cell viability in three concentrations: 0.0375, 0.075 and 0.150 mg.mL -1 . Only the butanolic fraction was active and showed IC50 = 22.7 μg.mL-1, therefore considered with high activity. The metabolic profile of the active fraction, the butanolic one, nine carbohydrates were found as majors compounds whose structures were not identified yet. In the crude extract, substances which may be candidates for the observed activity, either by synergism with the carbohydrates or separately, were identified, for example the gallic acid, which antineoplastic action is highlighted in the literature. These results demonstrate the relevance of substances resulting from the Cerrado plants and points out that the butanolic fraction obtained from crude extract of the pequi fruit peel as a promising option for the treatment of squamous cell carcinoma of the tongue. It is noteworthy, however, that tests were not performed in normal cells (not cancerous), making it necessary the extension of the study in this regard and also aiming the identity of the compounds found in the active fraction, as well as to understand their mechanism of action.

  4. Bráulio Ferreira Souza Bento. Consequências do estresse ambiental na comunidade de besouros Scarabaeinae (Insecta: Coleoptera) em ambientes de florestas estacionais deciduais.. Ronaldo Reis-Júnior, UNIMONTES, Agosto 2016.
    Abstract The order to assess the consequences of disturbances in living organisms, encourage scien- tists to develop cheaper and accurate biomonitoring techniques to determine the consequences of these disturbances.Our study tested the hypothesis that environmental stress in ontogene- sis period affects the morphology, distribution and fitness of adult organisms of Scarabaeinae community. For it was found that the fluctuating asymmetry (environmental stress measure) within the population decreases the weight and size of the specimens; the population of beetles Patos region has smaller individuals and more asymmetric than the region of Minas Gerais and the Scarabaeinae community has a distribution pattern according to the average fluctuating asymmetry. The studies were conduted in seasonal forests deciduous in regions of the states of Minas Gerais and Paraı́ba. The environmental stress during ontogenesis varied morphology and distribution of community and population, but did not affect the fitness. We believe that beha- vioral characteristics and biochemical present in these organisms are plugging the disturbances suffered during ontogenesis period not affecting the fitness of these organisms.

  5. Bianca Lima Botelho. Caracterização fenotípica e bioquímica da comunidade de rizobactérias em solo de floresta estacional decidual do Norte de Minas Gerais.. Henrique Maia Valério, UNIMONTES, Agosto 2016.
    Abstract The Deciduous Seasonal Forests are considered unique environments having peculiar characteristics such as high-grade leaf deciduousness and two well-defined annual seasons (dry and wet). In the soil are a range of microbial populations and the growth promoted by rhizobacteria in plants (PGPR) have attracted special interest, because they to produce hormones and to increase the availability of nutrients. Thus, this study aimed to isolate and characterize biochemically and genotypically, the Deciduous Seasonal Sorests soil rhizobacteria (DSF) and to evaluate the effects of seasonality and ecological succession on diversity, indole acetic acid production and phosphate solubilization. This study was conducted in the Conservation Unit State Park Lagoa do Cajueiro-PELC (Matias Cardoso city/ MG), in the two seasons, wet and dry, from three plots with three regeneration successional stages (early, intermediate and late). Soil samples were collected, subsequently diluted and plated in triplicate. After incubation at 30 ° for 24 hours, colonies were counted and purified according with different morphological characteristics and proceed to the quantification of IAA production by the colorimetric method and phosphate solubilization in solid NBRIP were done. The data were statistically evaluated in the program R. A total of 705 colonies were obtained in the rainy season and 404 in the dry season, these were classified into 27 morphotypes, 80% of microbiota was able to synthesize some amount of IAA, ranging from 0,03 a 11,5 μg/mL -1 , 10% of isolates had solubilizing activity of P-Ca, showing solubilization rates of 1,0 to 2.0. In general, seasonality been shown to correlate positively with richness, total abundance of rhizobacteria and synthesis of IAA, the latter were also affected by the intermediate stage of succession, since the phosphate solubilization shown to be affected by the dry season and the early stage of succession. The characterization of microbial communities existing in soil is extremely important providing support for further studies. This work brings new results regarding soil microbiota of rhizobacteria of DSF, activities and interactions between biotic and abiotic factors that influence these relationships. We concluded that seasonality and sucessionalidade influence on the community and activity of soil rhizobacteria Deciduous Seasonal Forests. Lattes PDF BibTeX

  6. Letícia Fernanda Ramos Leite. Estrutura da comunidade de galhas em uma planta super-hospedeira: testando a hipótese da competição em habitats xéricos. Marcílio Fagundes, UNIMONTES, Maio 2016.
    Abstract As forças bottom-up, top-down e as interações dentro do mesmo nível trófico determinam a organização das comunidades de galhas nos diferentes ambientes. No entanto, fatores de estresse (elevada radiação, estresse hídrico e menor disponibilidade de recurso) são barreiras para sobrevivência desses indivíduos, favorecendo uma elevada abundância de galhas nos ambientes xéricos. Nos ambientes com elevada abundância de indivíduos e o recurso (sítios para oviposição) é limitado, é possível que exista uma força competitiva capaz de atuar nestas comunidades. Neste sentido, estamos propondo que a competição interespecífica é uma força atuante na estruturação da comunidade de galhas em ambientes xéricos. Foram avaliadas sete populações de C. langsdorffii com características peculiaridades que formam um gradiente de estresse. Em cada população foram amostradas características vegetativas das plantas (indicadoras de estresse ambiental) e avaliado a coexistência das galhas dentro de um mesmo folíolo. O índice de coocorrência (C-score) observado foi comparado com o modelo nulo para aceite ou rejeição da hipótese biológica, sendo uma análise para cada população. Os valores de C-score observados em todos os habitats foram comparados com os parâmetros vegetativos indicadores de estresse. As galhas encontradas nos ambientes úmidos coocorrem livremente dentro do folíolo, já nos ambientes xéricos as galhas coocorreram menos do que o esperado pelo acaso, sustentando a nossa hipótese. Desta forma, assumimos que a competição é uma força estruturadora das comunidades de galhas nos ambientes xéricos. Lattes PDF BibTeX

  7. Sandro Lânio Abreu Paula. Variação no teor de ácido gálico da casca do fruto entre populações de pequizeiro (Caryocar brasiliense Camb.). Geraldo Aclécio Melo, UNIMONTES, Abril 2016.
    Abstract This study investigated the occurrence of variation between populations and throughout the development of the fruit in gallic acid content of the fruit skin of pequizeiro (Caryocar brasiliense Camb.). The dry mass of 1 g of fruit peel, the fruit volume and the water percentage from the fruit peel were determined as covariates. Fruits from a pequi population located in the municipality of Montes Claros / MG were used and distributed in two adjacent areas, a native (Cerrado stricto sensu) and another in a pasture area. They were also used fruits from another population in the municipality of Itacambira / MG. Gallic acid content was determined by High Performance Liquid Chromatography Efficiency, the moisture content and the dry matter of the fruit peels were determined by gravimetry and the fruit volume was estimated from fruit dimensions. The gallic acid content varied between individuals and throughout the development of the fruit, decreasing initially and returning to initial values in the mature fruit. There was no difference when comparing native and pasture area. However, there were differences between populations, the bigger content of gallic acid was in the population located in Itacambira / MG. There was also variation in relation to the moisture content and dry weight of 1 gram of the fruit peel over development between individuals, but not between areas and populations. The volume of fruit increased over development among individuals similarly in both areas. Apparently climatic factors seem to influence the gallic acid content of the fruit peel as well on a local scale, as in a spatial scale. However, other evolutionary factors, such as interaction with predators and dispersers, also appear to be responsible for the phenotypic variability of this trait in species. Lattes PDF BibTeX

  8. Euripedes Pontes Júnior. Análise da efetividade da gestão do Parque Nacional do Descobrimento/BA. Geraldo Wilson Fernandes, UNIMONTES, Abril 2016.
    Abstract One of the ways found to face the imminent degradation of natural environments was the creation of specially protected areas. However, the existing challenges for protecting biodiversity in these areas are varied, ranging from technical aspects related to the size, design and method of insertion of the conservation unit in the landscape to funding mechanisms of the National Protected Areas System - SNUG. Analyze the effectiveness of protected areas management is an essential step to properly calibrate actions aimed at ensuring that the objectives of its creation are achieved. This research aimed to evaluate the effectiveness of the Discovery of the National Park through the EMAP method (Evaluacion del Management of Protected Areas) as described in Faria (2004). The result of the analysis of efevidade management of the National Park by the Discovery was 37%, fitting to Standard Very Low effectiveness of management, which is the lowest level of the scale. This pattern is characterized by the fact that many missing elements to the management and this situation does not guarantee the permanence of the unit in the long term, which obliges the institution to make greater efforts on it. Under current conditions, management objectives are not achieved (Faria, 1997). The results obtained by each of the four areas of management analysis shows that the great weakness of the unit is related to the scope of planning, which reached only 24% of the total score.

  9. Joselândio Corrêa Santos. Comparing ground - based and remote sensing methods to assess phenological patterns along a successional gradient in a tropical dry forest. Mário Marcos do Espírito-Santo, UNIMONTES, Março 2016.
    Abstract The Normalized Difference Vegetation Index (NDVI) is one of recent tool to forestry and  phenological studies, but it still has some limitations in use, because of it observation of plants in  situ are still essential for interpolation and calibration of satellite and near-ground measurements.  We intend to answer the following questions: (1) What climatic factors drive vegetative  phenological patterns? 2) Are there differences in the vegetative phenology between years? 3) Are  there difference in the vegetative phenology between successional stages? and 4) How consistent  are the phenological patterns detected by ground observations and satellite imagery? The study are  was a tropical dry forest (TDF) in Mata Seca State Park (MSSP), Manga- MG, Brazil. We delimited   two transects in each six plot in the three successional stages early, intermediate and late, where we   used to quantify vegetative phenology using the Fournier Index (FI). We obtained NDVI values for   free in the NASA website. We correlated the average and minimum temperature (°C) and relative   humidity (%), and rainfall (mm).We used generalized linear model and circular statistics to test the   others hypothesis. Leaves had massive production in October and November in all stages. The  maximum of greenness reach in December and January, for FI and NDVI. All climatic variables  were significant and positively correlated with both methods. The minimum temperature showed  the highest correlation with both phenological variables. A few and punctual differences were  observed between successional stages. For NDVI, there were no difference between stages or years.  The NDVI and Fournier Index were strongly correlated for all successional stages and the relation   coefficient increased along the successional gradient. The temperature can affect the photosynthetic   metabolism and lower temperatures could indicate the onset of the dry season. Thus, plants are   evolutionarily conditioned to sprout out their leaves with the first clues of the beginning of the rainy   season. For this reason, there is a massive synchronization of leaf production that is independent of   the successional stage or functional group. The NDVI is less sensitive than ground-based method.  The vegetative phenological pattern of TDF’s are not so obvious as it supposed to be, it can be  affected changes in temperature, rainfall and the age of the forest. Direct observations of the plants  crown are more sensible to alterations in the forest dynamics, and it would be useful when  individual characteristics are important for the study. On the other hand, NDVI are costless, and it  possible to cover almost an unlimited area of interest. Lattes PDF BibTeX

    Abstract The babassu (Attalea sp.) is a native palm tree belonging to Arecaceae family, with wide distribution in Brazil. The Attalea vitrivir Zona occurs in the northern region in the state of Minas Gerais and Bahia Southwest, where the Cerrado is the predominant biome. The babassu is considered the largest native oil resource in the world and one of the main forest products in Brazil, and to contribute significantly to the economies of some states. Given the economic and social importance of babassu, analysis of the structure and genetic diversity of populations of A. vitrivir was carried out in five areas of two distinct regions, to characterize genetically the species. Twenty one pairs of microsatellite primers (SSR) were used success transferred species Orbignya phalerata (synonymy Attalea speciosa) for the species Attalea vitrivir. High genetic diversity values were found (He: 0.633 to 0.750), most within populations than between them, probably due to the isolation. The STRUCTURE software revealed that five populations sampled were grouped into two separate groups (K = 2). Coincides with the northern regions (greater differentiation) and south, and corroborated the results of the analysis of molecular variance (AMOVA) indicated that most of the genetic variability among individuals within populations (93.29%) than among populations (6,71%). The high genetic diversity in populations not included in the environmental protection area shows the need for further expansion of proposed conservation areas, since the occurrence of the species is restricted.

  11. Mariana Guimarães Vale Dupin. Políticas de uso da terra e desmatamento nas matas secas Norte-Mineiras entre 2000-2015. Mário Marcos do Espírito-Santo, UNIMONTES, 2016.
    Abstract The tropical dry forest has been largely converted to pasture and agricultural areas, directly affecting biodiversity, ecosystem services and social welfare. Estimated that 52% of 81.046 km2 of Brazilian tropical dry forests (TDFs) have already been converted to some kind of human activity. Regenerate tropical forests offers an effective carbon sequestration opportunity in the tropics, and simultaneously benefits the conservation of biodiversity and maintenance of ecosystem services. This study aims to answer the following questions: i) what is the extent of LUCC (deforestation, natural regeneration and net change in land cover) in TDFs in north of Minas Gerais between 2000 and 2015? ii) what are the factors that drive the intensity of these processes and how they are influenced by environmental policies and economic development? iii) what are the effects of light on human well-being indicators? We detected a considerable change in land cover, expressed in 9,825 km2 of deforestation and 6,523 km2 of regeneration, resulting in a net loss of 3,302 km2 and an annual change of -1.2%. The conversion of TDFs was directly affected by the municipality area, average declivity and the increase in the density of cattle, whereas the regeneration was significantly affected by the municipally area, the increase in protected areas, the average declivity and population density changes. The results indicate an improvement in the economic situation of the northern state of Minas Gerais, but these results should be analyzed with caution, since it also portrays a substantial improvement of the socioeconomic conditions in Brazil between the years 2004-2014. Secondary forests are essential for the maintenance of ecosystem services and biodiversity and therefore should be considered in the development of conservation strategies. It is necessary that specific policies are developed to promote natural regeneration in abandoned pastures and macroeconomic policies that drive and promote deforestation are reviewed, since that cause environmental impact without welfare gains.

    Abstract The macrophytes play important ecological functions in aquatic environments, but the understanding of the patterns and processes related to biodiversity of these plants still represents a challenge to theoretical and applied ecology. Thus, this work was studied the diversity of species of aquatic weeds in eight lagoons of the Middle Rio Doce, to increase knowledge about these plants in the region. They were evaluated: the influence of the littoral area depth and declivity in species succession of aquatic macrophytes; and how changes in the conditions of dry to rain season can affect the species composition in that lakes. The samples were done in March and September of 2005 that is correspond to wet and dry periods. A transect was created for different type of environment where, along it each 2 meters, a plot of 1 m2 was established the depth, and the area cover by each species of aquatic macrophyte were measured. Sixty-five species of aquatic macrophytes were collected. The results showed, the declivity of littoral area is positively related to higher species’ turnover rates, the same relationship was not found to the variable average depth. The results also showed a strong effect of drought in species composition of the ponds studied, with a decrease in the frequency of less resistant species and increase of more resistant species. The significant change in species composition between the rainy and dry presented by lakes, especially the Lagoa Carioca, can be translated into greater habitat diversity (beta diversity), important mechanism for maintaining long-term diversity, which demonstrates the importance of conservation .

    Abstract Studies on the structure of palm seedlings are scarce and may contribute to expand knowledge about the ecology of the species and to subsidize seedlings production. The objective of this study was to evaluate the development of the eophyll and the effect of light on Attalea vitrivir young plants, a palm native to Cerrado, with great potential for agro- industrial use. The ontogenesis of the eophyll was characterized by morphoanatomic assessments and the effect of shading levels (0, 58, 73 and 93%) was evaluated on the morphology of plants, anatomy and histochemistry of the eophyll, after 6 and 18 months of development. After germination, the cotyledon petiole extends deeper into the soil, which promotes the vegetative axis burial. Approximately sixty days after germination, the emergence of the first eophyll occurs below ground level. The plumule is composed of the apical meristem and two tubular leaf sheaths and, after germination, the development of two eophylls occurs. Eophylls are formed by a flat base and a blade with many folds and grow due to the action of a basal meristem. The shading level does not affect the thickness of the leaf tissue , distance between the ribs, stomatal density and presence of compounds of primary and secondary metabolism. The eophyll presents wide diversity of vascular bundles, which were grouped into three types. The formation of the first leaves below the surface and the adaptation of young plants to different levels of shading represent important adaptations to the species occurring in seasonal climate environments and anthropogenic areas.

    Abstract After a disturbance, natural regeneration follows a progression of stages, with a gradual enrichment of species and an increase in the structural and functional complexity. This work aimed to evaluate the regenerative potential an area on the banks of the river Pandeiros, impacted by cattle, after implantation of different restoration treatments. Were deployed eight treatments: open area (A), enclosure (C), fertilizer area (E), area with direct seeding (S), areas with planting seedlings with 2 or 4 m spacing (M2 and M4) and areas with planting (2 or 4 m) consortium with direct seeding (SM2, SM4). The treatments were applied on plots that were fenced (except treatment A), barred and fertilized (except treatments A and C). In the plots were established sub-plots of 4 m 2 and collected composed samples of soil. In these sub-plots, all individuals were sampled and woody species, counted the herbaceous species and invasive grass and estimated vegetation cover. The evaluations of natural regeneration and vegetation cover were made periodically over the course of 24 months. To examine the differences between the groups of plants, depending on the time and restoration treatments, we used the Linear Mixed Effect Model. To detect the ratio of groups of plants with the edaphic conditions and treatments variables was made a Canonical correspondence analysis. Was found a greater richness and abundance of woody in A (open area) and C (fenced), and there was no significant variation over time. For the herbaceous, there was a decrease in wealth over time and the greatest wealth of grass attacker was observed at 3 months of assessment in almost all treatments. The greatest vegetation cover was observed at 12 months in almost all treatments. Invasive grass species and herbaceous correlated positively with potential acidity, phosphorus and coarse sand and woody with potassium, and organic matter. There was no correlation between restoration treatments and edaphic conditions variables. Environmental restoration is a slow and unpredictable, where conclusive answers depend on the short-term and long-term. Lattes PDF BibTeX

    Abstract It is in the interest of the pharmaceutical and cosmetic industry to continually seek antimicrobial and antioxidant activity of vegetables containing phenolic compounds. The objective of this study was to evaluate and characterize the antimicrobial and antioxidant activities of hydroalcoholic extract from leaves of the species Carpotroche brasiliensis. We evaluated the in vitro antioxidant activity which determined the ability to scavenge free radicals, by using the model of radical (DPPH) and expressed in CoP50 (coefficient of performance) and as a reference the Trolox standard (synthetic antioxidant).The antioxidant evaluation was determined by the ability to scavenge free radicals, by using the in vitro model 2.2-diphenyl-1- picryl hydrazyl radical (DPPH) and expressed in CoP50.In the percentage of significantly lower antioxidant activity (P <0.05) compared to the standard concentration corresponding to the lowest concentration, 100 mg / mL only (11.02%), of antioxidant activity, whereas the Carpotroche brasiliensis extract in the lower concentration of 0.010mg / mL presents an equivalent antioxidant activity (87.45%), showing that the sample had a high-powered antioxidant activity. We evaluated the antimicrobial efficacy of the leaves extract which, even presenting MBC (minimum bactericidal concentration), was effective only at concentration of 400 μg/mL for (Pseudomonas aeruginosa and Staphylococcus aureus) and MBC (minimum bactericidal concentration) with no antibacterial efficacy but rather bacteriostatic. It can be seen that the phenolic compounds were determined with reactive test and the samples presented high content of tannins and flavonoids of Carpotroche brasiliensis species, and thus may be responsible for the activities described above.

The objective of this study was to evaluate and characterize the antimicrobial and antioxidant activities of hydroalcoholic extract from leaves of the species Carpotroche brasiliensis. We evaluated the in vitro antioxidant activity which determined the ability to scavenge free radicals, by using the model of radical (DPPH) and expressed in CoP50 (coefficient of performance) and as a reference the Trolox standard (synthetic antioxidant).The antioxidant evaluation was determined by the ability to scavenge free radicals, by using the in vitro model 2.2-diphenyl-1- picryl hydrazyl radical (DPPH) and expressed in CoP50.In the percentage of significantly lower antioxidant activity (P <0.05) compared to the standard concentration corresponding to the lowest concentration, 100 mg / mL only (11.02%), of antioxidant activity, whereas the Carpotroche brasiliensis extract in the lower concentration of 0.010mg / mL presents an equivalent antioxidant activity (87.45%), showing that the sample had a high-powered antioxidant activity. We evaluated the antimicrobial efficacy of the leaves extract which, even presenting MBC (minimum bactericidal concentration), was effective only at concentration of 400 μg/mL for (Pseudomonas aeruginosa and Staphylococcus aureus) and MBC (minimum bactericidal concentration) with no antibacterial efficacy but rather bacteriostatic. It can be seen that the phenolic compounds were determined with reactive test and the samples presented high content of tannins and flavonoids of Carpotroche brasiliensis species, and thus may be responsible for the activities described above.",

    Abstract Rocky fields are environments subjected to seasonal variations in water availability with well- defined dry and rain seasons. The strategies that guarantee the survival of many plants in these environments may include physiological and biochemical changes. In this study were analyzed changes in the metabolic profile in leaves of Gomphrena agrestis, growing under field conditions in order to associate them to the water availability of the environment and the phenological stages. At different times during the transition from the dry to rain season soil samples were collected for determination of moisture content and leaf samples to determine the biomass, relative water content, moisture content, content of total phenolic compounds, antioxidant activity, total soluble sugars content and glucose and to analyse the metabolite profile. It was observed that the plant starts and ends her reproductive cycle during the rainy season and goes into dormancy during the dry season. Changes in total soluble sugar content and glucose were consistent with osmoregulation strategy. Similarly, the content of phenolic compounds was higher at times of lower soil moisture and may be associated with both the osmoregulation and the defense against oxidative damage that can arise in conditions of lower water availability. In metabolic profile analysis was possible to observe more significant changes in the levels of malic acid, octadecanoic acid, D-glucose, glucopyranose, cinnamic acid, vanillic acid, L-threonic acid, pyroglutamic acid and glutamine. These changes may be associated with growth processes of the plant and strategies for dealing with water condition of the environment. The observed variations demonstrate that the plant has strategies to support periods of water stress, especially the maintenance of the high content of leaf relative water during the dry season, which may result from osmoregulation strategy.

    Abstract The Tropical Dry Forests (TDFs) are conditioned to strong climatic seasonality and are characterized by loss of tree leaves in the dry season. The soil seed bank in the TDFs includes the seeds viable in the litter and barried in the soil being considered the primary seed source with regeneration capacity in the disturbed area. The objective of the study was verify the floristic composition, richness and density of the seeds bank in differents successional (early, intermediate and late) and seasons (rainy-dry, dry, dry-rainy and rainy). The soil seed bank was sampled in four periods of the year, between 2013 and 2014. For this purpose, 18 plots were used divided into three successional stages (six plots for each stage). We observed 1,728 seedlings in the four samples, with 152 in the period of rainy-dry transition, in 197 samples of the dry season, 1,035 the dry-wet transition period and 344 in the rainy season. The rainy-dry season showed 42 seedling species, the dry season 24, the dry-wet season 59 and the rainy period 45 species. On the other hand, the relationship between stage and period had no significant correlation with the richness of the seed bank. The values obtained for the GLM abundance showed significant differences between all variables: stage, period of sampling and interaction between stage × period. The richness and abundance of soil seed bank showed a positive correlation with the chemical variables of the soil (Ca, K, V, P-Meh, pH, SB, t, T, Mg, H+Al). The initial stage of succession showed higher seedling establishment in the dry- rainy season, both for richness and abundance. This infers that the initial stage sequence is favorable to the input seedlings, that facilitate the seed dispersion, since they are more open areas. Thus, the spatial and temporal variations in richness and abundance of soil seed bank interfere in establishing populations in some environments. Some areas have demonstrated the ability to provide seeds remaining in the seed bank even after the disturbance and establish their seedlings. Lattes PDF BibTeX

    Abstract In dry tropical forests, the dynamics of plant communities is differentiated from tropical rain forests, since the main ecological processes, such as growth, reproduction and nutrient cycling, are conditioned to a longer period of water stress. The objective was to evaluate the annual performance of the tree community of a tropical dry forest in different successional stages. The study was conducted in the Parque Estadual da Mata Seca is located in the town of Manga, Minas 2Gerais, Brazil. For sampling the vegetation, they were marked 18 plots of 1000 m 2 , six plots in each successional stage. Samples were collected from 2006 to 2015. To assess the annual vegetation dynamics we used the number of individuals and basal area of each plot in each interval, and thus the dynamic parameters were calculated. To examine the differences of the parameter, depending on periods and stages, we used linear mixed-effect model. The data observed for the dynamics of the number of individuals and basal area indicate a maturing of tree communities in the early stages of succession, especially the increase in the number of individuals in the community, approaching the values with the most mature stage. However, values in basal area, differ greatly between stages. This fact shows that the time for these stages approach the structural values of mature forest will be long. In this way, the forest apparently tends to greater stability, represented by the decrease in dynamic rates, especially in the early stages of regeneration. Lattes PDF BibTeX

    Abstract Understand the dynamics of canopy communities remains a frontier of research, especially in Tropical Dry Forests. In addition, understand how the features of the species influences the structure of an ecological network is one of the most important issues in ecology, then this study aims to analyze the structure of ant communities in tropical dry forest canopies using ant-trees networks. Several factors can interfere on the distribution of arboreal ant communities and in our work, the height of the trees, the presence of extrafloral nectaries and the connectivity of crowns, were investigated to elucidate the ant-trees networks structure and the existence of the ant mosaics. Based on accumulated collections of two dry seasons and two rainy seasons, we have built a network in which were established 1,116 interactions between 79 ant species and 150 trees of 27 species. This network established that the tallest trees are more central in the community, although extrafloral nectaries and connectivity among crowns do not show significant effects. The ant community as a whole is marked by the dominance of species of territorial arboreal ants, which are six species representing 48.59% of the total species occurrence (439 interactions), present in 148 of the 150 total trees. We found the network separated in two modules statistically consistent: one of them Crematogaster goeldi, Camponotus melanoticus, Camponotus arboreus and the other Camponotus blandus, Cephalotes pusillus, Camponotus renggeri. Each module have typical tree height, and into each one there are two Camponotus species, but this Camponotus pair are diurnal and nocturnal foragers, in other words, beyond the use of specific tree height (spatial niche), they present unique temporal niches (day/night). This features confirming the ant mosaics in tropical dry forests canopies. Lattes PDF BibTeX

    Abstract The liana-tree interactions helps organizations uncover patterns in order to clarify the factors that enhance or inhibit the development and distribution of both. This study aimed to determine the effects of ecological succession on liana community and analyze their interactions with the tree community in a Tropical Dry Forest. We recorded 35 species of lianas, which Bignonia ramentacea (Mart. Ex DC.) LG Lohmann is the most common species and found mainly in advanced stages of succession. There were changes in the composition of the liana community and trees to the right of secondary succession, where 48.8% of liana species found in the intermediate stage also occurred in the late stage and 11% of the tree species found in the intermediate stage also occurred in the late stage . Along the successional gradient has been an increase in wealth and density of lianas and tree density following the gradient: Initial <= intermediate late. The wealth of trees differ between every stage reaching peak in the middle stage. One unimodal relationship between the density of vines and trees was found. The peak in liana diversity in intermediate stages is probably related to greater joint light availability and support for the growth of these plants. The values of nesting and modularity did not differ from the null model, noting that the liana-phorophyte interaction is highly widespread and the network structure is not different from chance. Interactions in the liana-phorophyte community seem to follow an opportunistic growth strategy, primarily shaped by morphological and physiological characteristics of the hosts at the expense of its identity. A better understanding of the interactions between lianas and trees will allow a greater understanding of natural regeneration pathways in tropical forests, with practical applications for conservation and management of these ecosystems.

    Abstract The Tropical Dry Forests are considered one of the most endangered tropical forests and with little knowledge, though they account for about 42% of the world's rainforests. Thus, the arbuscular mycorrhizal fungi (AMF) can play an important role in these ecosystems. The objective of this was to determine the richness and abundance of arbuscular mycorrhizal fungi in deciduous seasonal forest in northern Minas Gerais, Brazil, soil samples were collected during the rainy and dry seasons in the Parque Estadual da Mata Seca in the North of Minas Gerais, in plots previously marked in different successive stages classified as initial (15 years regenerating process), intermediate (25 in the regeneration process) and late (more than 50 years without intervention). The soil samples generated (3 per stage, totaling 27 samples) were taken to the laboratory for extraction, counting and identification of spores and physicochemical characterization. 60 AMF species belonging to 10 families were found. The Glomus and Acaulospora genus higher numbers. Overall, plenty of spores differed between stages (p = 0:02) and the wealth of AMF species was affected by season (p = 0.01), with the greatest wealth dry season. Regarding the composition of species, this did not differ between stages (p = 0.038) only between stations, being the dry season showed a significantly different composition of the rainy season (p = 0.001). The soils are predominantly acidic and soil variables used did not influence the replacement of species (p = 0.77). Overall, seasonality has a strong influence on the AMF diversity, presenting the dry season richer, and the AMF composition was also affected station. Lattes PDF BibTeX

    Abstract Dentre as diversas formações vegetais no Cerrado se destacam as florestas ou vegetações ripárias que representam áreas de transição entre os ecossistemas terrestre e aquático e são influenciadas pelo clima, geomorfologia e condições de solo. As zonas ripárias são responsáveis pela integridade das bacias hidrográficas, já que elas estabelecem funções hidrológicas importantes na manutenção dos riachos, contribuindo para o aumento do volume de água do riacho, regulando a quantidade, armazenamento e vazão da água mesmo em períodos de secas, estabilização das margens, além da manutenção da qualidade da água. Nesse sentido, a dissertação aborda aspectos relacionados à dinâmica de matéria orgânica alóctone em zonas riparias principalmente voltados a decomposição desse material em um riacho de cabeceira no Cerrado.

As zonas ripárias são responsáveis pela integridade das bacias hidrográficas, já que elas estabelecem funções hidrológicas importantes na manutenção dos riachos, contribuindo para o aumento do volume de água do riacho, regulando a quantidade, armazenamento e vazão da água mesmo em períodos de secas, estabilização das margens, além da manutenção da qualidade da água.

    Abstract The interactions between herbivores and host plants can be mediated by chemical signals emitted by microorganisms. Insects, including Pachymerus cardo, use and depend on chemical compounds throughout their lifecycle. These chemical signals can guides them in behavioral responses. The aim was to evaluate the interference from the presence of two species of isolated fungi decomposers in Acrocomia aculeata fruit in oviposition site selection behavior by P. cardo. Two Bioassays were performed. In the first, with isolates fungi of A. aculeata fruit. And the second bioassay was triple-choice arena, consisting of three treatments (healthy fruit, fruit inoculated with fungi and Control), which the insect was placed in the central arena and had equal access to three choices. Was subsequently built a hierarchical ethogram for understanding the behavioral pathways of P. cardo in front of chemical volatiles emitted by fruits colonized by fungi. The data were analyzed by building GLMs and descriptions of behavioral events in the selection of oviposition site. The healthy fruit treatment in Arena was significantly (P <0.05) selected by P. cardo in compared to other treatments. The Beat Wing behavior (BA) was associated in response to the choice of healthy fruit being P <0.05, but the behavior categories expressed by P. cardo did not differ among the tested fungi. Thus it was verified that the fungi presence modifies the oviposition site selection behavior of P. cardo. These data are relevant to ecological understanding of the emissions of chemical compounds by fungi as seed predatory behavior modulators. Lattes PDF BibTeX

    Abstract The traditional communities are groups differentiated human who develop their way of life from an intense relationship with nature; what the provides a broad knowledge about the natural cycles and enables you to transmit this knowledge to other generations. Among such groups may be cited the vazanteiros, traditional group that develops its practices and way of life from a direct relationship with the San Francisco river, by the practice of agriculture in wetland environments and the fishing in the river and ponds. The work presented here aimed to understand the relationship of the vazanteiros Island of Pau in League with your territory from their knowledge and practices traditional ecological addressing descriptive way to recovery and ways of obtaining natural resources used, as well as management techniques and possible impacts generated the light of its environmental history. The community is comprised of 52 families, which currently limit its occupancy and completion of its activities in a limited area in front of the State Park of the Dry Forest, on the left bank of the river San Francisco (municipality of Manga - MG) as a result of a long historical process of expropriation. Semi-structured interviews and applied questionnaires with 14 vazanteiros of different families in the period of October 2013 the July 2014. The information about the management history revealed the presence of areas executioner calls ( higher areas , not very fertile ) , lagadiços ( areas with high moisture and organic matter ) , capon umbu ( native forest ) , Wadi ( high areas with remanesceste of native forest ) , poultry ( area where there was the ongoing process of planting ) , ebb ( near the river areas that are above the lagadiços ) , bleeders ( connectors between the river and the lakes and among the lagoons , where they could not plantations be made ) in addition to ponds, and the São Francisco River as a source of fish as well as shelter for Governor of known social rules, mystical being known by Caboclo d'Agua. These areas were managed during the period prior to the process of expropriation of the community, while respecting the periods of drought, flood and ebb tides of the Sao Francisco River. Currently it is done the management of areas known to lameiro (area of slope to the river), Vazante (middle display area) and Sequeira (areas high). Each area was therefore used for the cultivation of species and management practices specific. The access to the different areas and the sum of the activities of agriculture and fisheries the guaranteed to obtain a larger amount of resources throughout the year in order to comply with the natural cycles and the intervals for the recovery of the areas explored. The non-completion of practice management by vazanteiros has brought negative impacts on local biodiversity. Lattes PDF BibTeX

    Abstract O conhecimento e a caracterização da distribuição geográfica de organismos é uma das tarefas básicas da Ecologia sendo uma questão complexa, principalmente quando as espécies ocorrem ao longo de gradientes geográficos, climáticos e de vegetação. O gênero Callicebus é amplamente distribuído na América do Sul a leste dos Andes, ocorrendo em quase todos os principais biomas. Atualmente são reconhecidos cinco grupos: Torquatus, Cupreus,Moloch, Donacophilus e Personatus. O grupo Personatus está restrito à Mata Atlântica e Caatinga do leste do Brasil. Vários autores apontam dificuldade na identificação dos táxons deste grupo. O objetivo desse estudo foi definir os limites atuais de distribuição de Callicebus personatus e mapear a área de ocorrência da espécie na região norte do estado de Minas Gerais. A região de estudo foi estabelecida de acordo com as informações sobre a distribuição geográfica do gênero de estudo existente na literatura e com o auxílio do Sistema de Informações Geográficas (SIG). Para atrair os guigós e eliciar respostas, utilizamos equipamento de playback, com uma gravação feita a partir do CD “Sounds of Neotropical Rainforest Mammals” Das 29 localidades visitadas que compreendem norte e região central do estado de Minas Gerais, em três novas localidades foram registrados Callicebus personatus, nos municípios de Claros dos Poções, Francisco Dumont e Montes Claros. Tal espécie apresenta característica de coloração e distribuição geográfica que ainda não haviam sido citadas na literatura. Lattes PDF BibTeX

    Abstract The palm Acrocomia aculeata, popularly known as Macaúba, features a large economic potential for the production of biodiesel. Palm fruits predation has been often related to insects of Bruchinae subfamily (Coleoptera: Chrysomelidae). Fruits are attacked by decomposing fungi these are not to be recognized by the seed predator. This study aimed to evaluate the profile of volatile compounds released by intact fruits of macaúba and colonized by the fungus Fusarium sp. and their effect on the oviposition behavior of Bruchinae P. cardo females. The decomposer fungus Fusarium sp. was grown on the fruit of macaúba for extraction and infochemicals identification. The volatiles were extracted by static headspace and analyzed by gas chromatography coupled to a mass spectrometry. In addition to volatile, the other components of fruits were identified through analysis of the total extract of the fruits of A. aculeata. The extracts containing the volatile fruit were used in bioassays in olfactometer "Y" for evaluating the response of mated females of P. cardo. The P. cardo females responded to the fruit extract intact and also to the infested fruit extract. When were submitted to the fruit extract intact in contrast to the infested fruit extract, they showed no preference. It was found that there was a difference in volatile profile between the two extracts. However in bioassays this difference was not perceived by P. cardo females. Possibly the concentration of extract used, was not adequate to enable the insect to make the differentiation between the two extracts. Thus more studies are needed order to be able confirm that the protection which the fungus promotes to the fruit avoiding the oviposition of Bruchinae is mediated by volatile. The discoveries of clues which would be involved in this interaction needs to be better understood because of the importance of the survival of the plant propagules and preserve the fruit of integrity allowing a better use of it.

    Abstract Brycon devillei (Jequitinhonha’s piabanha) and the Steindachneridion amblyurum (Jequitinhonha’s surubim) are two endemic and threatened species from Jequitinhonha river basin. There are no available data about them at the scientific literature. Some of these species have been caught during the events at the Hydroelectric Power Plant Irapé. We have featured the arresting in order to help for the knowledge of these species. From 2011 to 2015, it was made monthly species collections. From October to February it has been caught sixteen surubins and thirty piabanhas. Alive samples have been forwarded to the Machado Mineiro Environmental Station. All the samples arrested were adults in reproductive stage. This stage was checked by macro and microscopic analyses. Both surubins and piabanhas were caught in raining period and on those days when the reservoir was filing. The relation between the number of species arrested and the raining days was important to the surubim (p<0.003) and for the piabanha (p<0.002). Concerning the level it was just meaningful for the piabanha (p<0.04). As bigger as the level, the amount of species has been smaller. When we have checked the arrest of the two species at the same time, it was meaningful the relation with the rain (p<0.001). However we have checked an impacted region without importance regarding to the conservation, but even it still contains a certain individuals of these species. Therefore, we consider that the Hydroelectric Power Plant Irapé reservoir is an important site in the maintenance of adults, at least in the short term and we recommend that audited the area of the reservoir during the days of rain.

  29. Raquel Andrade Rodrigues. Malária em aves silvestres e distribuição de culicídeos em uma área de Floresta Tropical Seca, Minas Gerais, Brasil. Magno Augusto Zazá Borges, UNIMONTES, 2015.
    Abstract A malária aviária é uma doença infecciosa comumente transmitida por mosquitos da família Culicidae e acomete aves de diversas espécies, podendo desempenhar um papel importante como fator limitante na distribuição e abundância de aves florestais nativas. Os objetivos desse estudo foram: Verificar a presença de hemosporídeos causadores de malária nas aves do Parque Estadual da Mata Seca – PEMS; os mosquitos potencialmente transmissores; e relacionar isso aos fatores ecológicos como regeneração florestal e sazonalidade. Para isso, foram testadas as seguintes hipóteses: 1) a prevalência de malária em aves varia em função do período do ano; 2) a sazonalidade e a regeneração florestal influenciam na riqueza, abundância e composição da comunidade de aves e mosquitos; e 3) a regeneração florestal e a sazonalidade influenciam na prevalência de malária em aves. Realizou-se coleta dos mosquitos através de coleta ativa e armadilha de Shannon e coleta e análise molecular do sangue das aves capturadas com rede de neblina, em três diferentes estágios sucessionais do PEMS no início e fim das estações seca e chuvosa entre os anos 2013 e 2014. O estágio de sucessão influenciou na prevalência de malária nas aves, com maior prevalência encontrada no estágio inicial. Apesar da explosão na riqueza e abundância de mosquitos verificada no início do período chuvoso, este fator não influenciou na prevalência de malária. Acredita-se que os mosquitos com maior abundância nesse período não sejam os vetores da malária. A riqueza e abundância de mosquitos foram maiores no estágio inicial no período chuvoso. A riqueza de aves não variou ao longo do ano e nem entre os estágios. Porém, a abundância de aves foi maior no estágio inicial no final do período seco. A maior prevalência de malária ocorreu no estágio inicial, o que coincidiu com a maior riqueza e abundância de mosquitos neste local ao longo de todo o ano. Embora os presentes resultados devam ser interpretados com cautela, sugere-se que os mosquitos da tribo Mansoniini sejam os responsáveis pela vetorização da malária em aves na área de estudo, devido a sua constante abundância ao longo do ano e a proximidade do estágio inicial à Lagoa da Prata, onde esses mosquitos encontram condições para sua reprodução durante todo o ano.

O estágio de sucessão influenciou na prevalência de malária nas aves, com maior prevalência encontrada no estágio inicial. Apesar da explosão na riqueza e abundância de mosquitos verificada no início do período chuvoso, este fator não influenciou na prevalência de malária. Acredita-se que os mosquitos com maior abundância nesse período não sejam os vetores da malária. A riqueza e abundância de mosquitos foram maiores no estágio inicial no período chuvoso. A riqueza de aves não variou ao longo do ano e nem entre os estágios. Porém, a abundância de aves foi maior no estágio inicial no final do período seco. A maior prevalência de malária ocorreu no estágio inicial, o que coincidiu com a maior riqueza e abundância de mosquitos neste local ao longo de todo o ano. Embora os presentes resultados devam ser interpretados com cautela, sugere-se que os mosquitos da tribo Mansoniini sejam os responsáveis pela vetorização da malária em aves na área de estudo, devido a sua constante abundância ao longo do ano e a proximidade do estágio inicial à Lagoa da Prata, onde esses mosquitos encontram condições para sua reprodução durante todo o ano.",

    Abstract Rock Field areas have a well-defined seasonal variation of water availability which makes the vegetation of these places present adaptations in order to survive through those variations. Gomphrena agrestis Mart. is a rock field species with thickened underground structure, a characteristic that can be a strong indicator of the correlation between the solute accumulation in this organ and a mechanism for drought tolerance. Therefore the aim of this study is to check whether quantitative changes in the content of nonstructural carbohydrates in underground structures of Gomphrena agrestis are related to water environmental conditions. The study was conducted with G. agrestis plants originated from the Environmental Preservation Area "Conjunto Paisagístico Serra Resplandecente" in the city of Itacambira-MG (16 ° 59'47 "S, 43 ° 20'01" W). Rainfall average and temperature data were obtained monthly. During fortnightly expeditions, 15 individuals of the species were randomly selected within the study area and by direct observation was noted the presence of phenophases: budding, flowering, fruiting and senescense. Soil samples were collected to obtain the moisture content. Samples of 200 mg of the underground part of each individual were used for the extraction of soluble carbohydrates and these extracts used to perform quantitative analysis of total soluble sugars, glucose and fructose by specific colorimetric methods. The osmotic potential of underground structures and relative water content (RWC) (%) were determined. Data were analyzed using the R R[2:14] software (R Development Core Team, 2011). Generalized linear models, GLM's were built with normal distribution using environmental and biochemical indicators of water status in the plant as variables. The comparison between the values obtained in the determination of total sugar, fructose, glucose, soil humidity, osmotic potential and relative water content during the collections was made by the confidence interval at 95% significance level. The G.agrestis species is inserted into a well-marked seasonality region. Variations in the contents of carbohydrates were analyzed and barely noticeable, so it was not possible to say that there is a direct relationship between them and plan strategies such as osmotic adjustment. These variations may be related to phenological moments in plant, energy demand and photosynthetic activity rate during the study period. By phenological data it became clear that the escape of water restriction condition is part of the G. agrestis strategies to survive in Rocky Fields areas. Lattes PDF BibTeX

    Abstract The riverine communities of the São Francisco River for years have been in a relationship with the living environment, accumulating experience, developing knowledge and beliefs about this ecosystem. The traditional ecological knowledge of Barra do Urucuia fishermen is broad, covering issues such as reproductive, time and place of spawning, sexual dimorphism, parental care and reproductive behavior; ecological aspects, the importance of lagoons and biological cycle of the species; besides the knowledge of species little studied as pirá (Conorhynchos conirostris), a fish listed as threatened of extinction, but abundant in the study area. This prohibition causes discontentment on the part of fishermen, because the species has social and economic importance for them. In view of the fact that this social demand, we tried to work with the reproductive biology of pirá, determining the basic parameters such as period and the reproductive peak, fecundity and size at first maturity, which are important factors for fisheries management, thus seeking to promote a dialogue on the current status of the species. We devoted here also the discussion of the management model adopted in the country, proposing a change in management, which would then consider the participation of fishermen and their knowledge in the management process of fishing resources. For this, were related benefits of this merger in a shared management process causing this to be truly effective and equitable. Lattes PDF BibTeX

  33. Daniel Costa Paula. Efetividade de faixas de mata nativa em regeneração entre talhões de eucalipto na manutenção da diversidade da avifauna local. Waldney Pereira Martins, UNIMONTES, Maio 2014.
    Abstract A rápida e intensa conversão de ambientes florestais em pequenos fragmentos e áreas agroflorestais tem sido um dos principais responsáveis pela degradação da biodiversidade em ecossistemas terrestres. Nas chapadas entre os rios Jequitinhonha e Araçuaí, na porção central da Cadeia do Espinhaço, importante região de interesse ecológico para conservação já que apresenta três distintos biomas, Caatinga, Cerrado e Mata Atlântica, a silvicultura de eucalipto hoje representa a maior ameaça para avifauna local. A fim de verificar se técnicas de manejo praticadas em fazendas particulares de eucalipto estão sendo efetivas na conservação da avifauna local, foram realizados levantamentos comparativos, entre estreitas faixas de mata nativa em regeneração interligadas à fragmentos, e em fragmentos após cinco anos do último monitoramento. O estudo foi conduzido entre 2010 e 2012, sendo utilizado pontos-fixos para amostragem das aves em 64 pontos, que foram locados em diferentes fitofisionomias do Cerrado(CE) e em áreas de Mata Semidecídua(MS). Metade dos pontos foram estabelecidos em fragmentos de diversos tamanhos, e o restante foi locado em duas faixas estreitas de mata nativa em regeneração que foram abandonadas para servir como corredor para a fauna local. Foram registradas 175 espécies nos dois tipos florísticos, sendo 113 espécies para o CE, e 125 espécies para a MS. No CE a abundância e riqueza na faixa nativa foram superiores aos fragmentos, padrão contrário para a MS, onde os fragmentos apresentaram valores de riqueza e abundância superiores à faixa nativa. Na comparação de riqueza entre faixa nativa e fragmentos, foi encontrada diferença significativa para o CE (p=0,005), o mesmo não ocorreu para a MS. Ao comparar a composição de espécies entre os fragmentos e faixas nativas nos dois tipos florísticos, foi encontrado o mesmo o padrão para ambos ambientes. Onde a comunidade de aves se diferencia entre a faixa nativa e os fragmentos, nos dois ambientes. Lattes PDF BibTeX

  34. Larissa Danielle Carvalho Barros. Nı́vel de dano causado por cupins (Insecta: Isoptera) em plantios de cana-de-açúcar irrigada. Ronaldo Reis Júnior, UNIMONTES, Maio 2014.
    Abstract A herbivoria é uma das mais importantes interações animal-planta exis- tentes. Eles podem consumir todos os tipos de tecidos vivos dos vegetais e gerar danos que podem ocorrer em qualquer fase do ciclo de vida dos vegetais. No entanto os vegetais apresentam muitos tipos de defesas contra os insetos herbı́voros que vão desde defesas fı́sicas (pêlos e tricomas) a defesas quı́micas (compostos de ação tóxica ou repelente). Alguns vegetais podem sobreviver ao ataque de herbı́voros através de mecanismos de tolerância. A tolerância é a capacidade de minimizar as perdas no fitness devido a herbivoria. Ela se divide em três tipos: (1) Compensação insuficiente, (2) Compensação com- pleta e (3) Sobrecompensação. As interações entre plantas e seus herbı́voros são de grande importância uma vez que, estes insetos invariavelmente se tornam pragas em várias plantações agrı́colas inclusive na cana-de-açúcar. Uma das principais pragas de canaviais são os cupins subterrâneos que po- dem ocasionar uma redução de mais de 10 toneladas de cana por ano. Assim o presente trabalho teve como objetivo avaliar o nı́vel de dano causado por cupins em plantios de cana-de-açúcar irrigada testando a seguinte hipótese: o aumento da infestação de cupins em canaviais causaria uma maior produ- tividade baseando-se na idéia de sobrecompensação. Para isto foram sele- cionados 100 pontos em dois talhões de cana-de-açúcar dentro da empresa Sada Bio-Energia e Agricultura. Estes pontos possuı́am taxas de infestações diferentes para que podessemos avaliar a influência do aumento da infestação no peso seco da cana e brix. Nossos resultados mostraram um aumento no peso seco da cana conforme aumentava-se a taxa de infestação. Isto pode ser um indicativo de que as canas estariam sobrecompensando os danos sofridos pelos cupins. Apesar destes insetos serem considerados pragas eles exercem funções que modificam a fertilidade e porosidade dos solos em que habitam. Estes benefı́cios podem ter colaborado também para o aumento do peso seco da cana. Em relação ao brix não houve alterações do seu teor no caldo ao longo do crescimento da infestação. Os cupins podem não estar afetando a taxa fotossintética das canas e com isto a produção de sacarose não se altera. Outro alternativa seria, a dos cupins não causarem danos suficientes na cana ao ponto dela deslocar recursos para a produção de compostos de defesas e afetar, assim, a produção do brix.

  35. Karen Mirele Caldeira. Variação temporal de aves insetívoras que utilizam o sub- bosque em uma Floresta Estacional Decidual do norte de Minas Gerais. Lemuel Olívio Leite, UNIMONTES, Maio 2014.
    Abstract A dinâmica e estrutura das comunidades animais podem variar em escala espacial e/ou temporal, levando a mudanças nos padrões de abundância relativa, riqueza e composição de espécies. Tais mudanças foram bastante estudadas com relação às aves insetívoras que utilizam o sub-bosque em ambientes úmidos, no entanto, poucos foram realizados em ambientes sazonais, como as florestas deciduais, às quais se apresentam geralmente como um mosaico em diferentes estágios de sucessão ecológica. Em razão desse grupo de aves ser territorialista, ter baixa mobilidade, apresentar um elevado grau de especialização ecológica e sensibilidade às mudanças em populações de presas das quais se alimentam, conhecer como a comunidade de aves insetívoras que utiliza o sub-bosque muda ao longo do tempo pode mostrar como a sazonalidade e a sucessão ocorre em florestas estacionais deciduais. Desse modo, o objetivo desse trabalho foi verificar como a riqueza, abundância e a composição de aves insetívoras que utilizam o sub-bosque variam em relação à sazonalidade climática e à regeneração natural em três estágios sucessionais - inicial, intermediário e tardio, em uma Floresta Estacional Decidual localizada no Parque Estadual da Mata Seca, norte de Minas Gerais. O estudo foi realizado entre outubro de 2007 e junho de 2013, num total de seis anos. Em cada ano foram realizadas quatro coletas, às quais correspondem ao final da estação chuvosa (FC), início da estação seca (IS), final da estação seca (FS) e início da estação chuvosa (IC), sendo utilizadas redes de neblina para a captura das aves. No estágio inicial, a riqueza diferiu entre as estações e entre os anos, enquanto a abundância apenas entre as estações. No intermediário, houve diferença significativa na riqueza e abundância somente entre as estações. No tardio, houve diferença significativa somente com relação à abundância, a qual variou apenas entre as estações. A composição de espécies mostrou o mesmo padrão nos três estágios. Houve variação na composição de aves entre as estações, mas não ao longo dos seis anos de regeneração natural em cada estágio. Com relação às espécies indicadoras, de modo geral, foi observado um baixo número de espécies características em relação às estações em cada estágio, considerando o total de espécies capturadas em cada um. Diante de tais informações, as aves insetívoras que utilizam o sub-bosque na Floresta Estacional Decidual estudada, de modo geral, apresentaram variação na riqueza, abundância e composição de espécies significativamente relacionadas à sazonalidade climática, como era esperado. Tal observação indica as mudanças nos aspectos estruturais da comunidade de aves insetívoras 7que utilizam o sub-bosque na FED do PEMS estão mais relacionadas às mudanças em uma escala temporal menor, ou seja, entre as estações, do que a mudanças estruturais na vegetação ao longo dos anos. Isso sugere que a sazonalidade climática é o principal fator que estrutura a comunidade de aves na floresta estudada. Lattes PDF BibTeX

    Abstract Seasonal environments are known to exhibit periods of resource scarcity and environ- mental changes, such as the decrease of canopy cover, both associated with the rainfall. In order to supplement their energy demand, birds that live in these environments must introduce changes in their foraging activity and in their diet. The main purpose of this study was to evaluate whether the foraging behavior and diet of the insectivorous and stem climber bird Lepidocolaptes wagleri (Passeriformes: Dendrocolaptidae) are influ- enced by seasonality. The study was conducted in the Mata Seca- MG State Park, where observations of the behavior were made in dry and rainy seasons and the diet was assessed using samples of stomach contents of individuals captured with mist net. The study of the foraging behavior of the species was done from 29 observation sessions, in a sampling effort of 126 hours. Were obtained 29 observation sessions, in a sampling effort of 126 hours, from which was describe the foraging behavior of the specie. Results showed that the maneuvers frequency of prey capture and foraging sites used by L. wagleri did not vary between the seasons, which can be associated with high behavioral specialization characteristic of this species. According to other studies, the participation of the Wood- creeper-wagler in mixed flocks was a frequent event and not dependent of the sampling period. Among the 17 samples of stomach contents obtained, 13 samples belonging to the dry season and 4 to the rainy season, there were possible to identify 11 categories of food items. Refuting the proposed predictions, there were no differences in the richness and the composition of food items consumed in each season. This result can be explained based on food restriction imposed by reliance on vertical perches. Another fact to this is that L. wagleri find the same kinds of prey in the trunks of trees in both seasons. In the other hand, the abundance of items found in the diet was statistically greater in the dry season, period in which the consumption of social insects is increased. Overall, the resultsviii suggest that L. wagleri has limited behavioral plasticity in contrast to the relatively di- verse diet. This study was the first one that looked into the parameters of foraging behav- ior and diet of the Woodcreeper-wagler and the suggestion, for further work, is to perform the sampling of spatio-temporal dynamics of stem arthropod in order to make direct cor- relations between foraging behavior and the diet of the species.

    Abstract The hypothesis of habitat heterogeneity is one of the factors that may explain the distribution patterns of diversity and dynamics of organisms. It assumes that structurally complex habitats may provide more niches and diverse ways to exploit environmental resources and thus increase species diversity. However this diversity is threatened mainly due to human actions that cause processes of habitat conversion and fragmentation. This leads to a decrease of diversity , and can often lead to loss of functional groups with deleterious consequences for the provision of such services in medium and long term. In relation to these issues is important to understand the relationship between organisms and their ecosystem functions with diversity. In this case, the beetles ( Coleoptera : Scarabaeidae ) are considered as excellent models for study because they are good indicators of cost - benefit, especially in studies that focus on the consequences of disturbances of habitats. Thus this work aims to evaluate the effects of environmental degradation on the attributes of the community, defined by: richness and abundance of beetles, richness and abundance of beetles of each functional guild and species size. Regarding ecological services removing feces and seeds were evaluated according to the metrics of the community and the influence of the landscape arising from the degradation processes were evaluated. After the completion of the work a total of 3908 individuals distributed among 18 genera and 44 species were collected. Through the construction of generalized linear models it was found that the intensification of land use leads to in a decrease in the richness of beetles and that the functional guilds can be applied. Regarding ecological services higher values were found in forests with trend of decreasing in other analyzed areas. In relation to the functional guilds there was a reduction in their values according to the intensification of land use, but the relationship between the variables was intrinsic to each group.

    Abstract Ecological processes operating at different temporal and spatial scales determine the distribution of diversity on the planet. At local scale, ecological processes such as interspecific interections, sum to abiotic conditions and resource (availability and variety) are more important. While at regional scale, historical processes, such speciation, extinction, and dispersion events are more important. 2. The present study aimed to understand how ecological processes determine ant community structure at different spatial scales. So, ant communities of Tropical Dry Forests (TDFs) (Cerrado, Cerrado-Caatinga transition and Caatinga) were evaluated, and the following hypotheses were tested: (i) the ant composition change along ecological succession gradient, and differs between FTSs inserted in different vegetation areas; (ii) the richness and density of trees determine the ant richness and beta diversity (β) in FTSs; and (iii) the richness and beta diversity (β) increase along ecological sucessional gradient in FTSs. 3. The FTSs studied have very different ant fauna with only eight species shared among them. FTS inserted in the transition was the richest in terms of species number, while the FTS inserted in the Cerrado showed the highest β diversity. Moreover, the richness and beta diversity of ants were positively affected by the wealth of trees in FTSs, only when regional scale was considered. 4. FTSs fragments inserted in different regions have different ant faunas, which possibly suffered strong influence of evolutionary history of each fragment, and ecological conditions of the vegetation domain in which they are inserted. Moreover, tree richness plays an important role as determinant of ants in FTSs at regional scale. We also emphasize the importance of conservation of transition regions, as they are key habitat that houses a wide number of species typical of more than one environment. Lattes PDF BibTeX

    Abstract Knowledge of the variation of seed rain contributes to the understanding of reproductive processes and dynamics of ecosystems can support programs to restore degraded areas . Projects to restore degraded environments require tools to assess the progress of the restoration. Ecological indicators that comprise these tools allows us to interpret the situation of the area to intervene . The objective of this study was to evaluate the seed rain as an indicator of ecological restoration in areas of riparian zones in the Federal District . 132 seed collectors were installed in two areas of riparian forests that differ in history of land use and landscape around ( Rio Jardim and Capão Comprido) . In each area plots to evaluate the contribution of seed rain in different ecological restoration techniques were demarcated. Each technique or combination of more than one was considered as treatment (nucleação de Anderson , linha de recobrimento e diversidade, poleiros, nucleação de Anderson + poleiro, and mata remanescentes). In each area different treatments were installed (according to the size of the area) , with three replicates (plots) . Diagonal of each plot of restoration treatments was distributed four collectors of seed rain (50 x 50 cm , 15 cm of soil , nylon mesh of 1 mm 2) . As each treatment had three repetitions, therefore 12 collectors / treatment / month. The material deposited in the traps was collected monthly for one year (March 2012 to February 2013 ) , in paper bags and screened at the Laboratory of Plant Biology (EMBRAPA Cerrados) and Laboratory of Conservation Biology (UNIMONTES). The seeds were separated with the aid of stereomicroscope and identified and quantified when possible in cash and dispersal mode . In Rio Jardim area was sampled in total 100.040 propagules (8337sem/m 2 ) and 4053 (1351m 2 ) and MR 96987 (10777sem/m 2 ) in the APR. In Coité (Capão Comprido) was 74,316 propagules (3539sem/m 2 ) and 5718 (1906sem/m 2 ) and MR 68598 (3811sem/m 2 ). With the largest quantities represented by invasive species Urochloa decumbens (Stapf)RD. In areas syndrome dispersion predominant in the area in the restoration process (APR) was anemocoric and remnant forest "non anemochory " was prevalent . Predominated seed sizes small (<2mm) in both areas . Variation occurred in the supply of seed rain between the months being the peak observed for the Jardim area in April and the Coité was in February . In both areas the differences between the supply of seed rain in APR (area being restored) and MR (remaining forest) were observed . In Jardim in the treatments with highest intakes of seed rain in abundance and richness were T3 (control ) and T4 (remaining forest) , respectively (p<0.001) . In Coité area were, respectively, T5 (diversity and coating line) and T7 (remaining forest) (p < 0.001). With the results obtained for both areas is possible to observe that the seed rain reflect the different situations in each area responding to small variations reflecting the conservation status of each environment and allowing to draw conclusions within the landscape . Because of this accuracy, sensitivity and measurability seed rain can be used as an indicator of ecological restoration in riparian areas , allowing the study to extract information about the regeneration capacity of the ecosystem . Can be used as an indicator of the potential for regeneration or as an indicator of self-maintenance to support interventions and best choice of methodologies for restoration. Lattes PDF BibTeX

  41. Sarah Freitas Magalhães Silva. Determining the K coefficient to Leaf Area Index estimations in a Tropical Dry Forest. Gerardo Arturo Sanchez-Azofeifa, UNIMONTES, Fevereiro 2014.
    Abstract The aim of this study was to determine the K coefficient in different successional stages of a Brazilian Tropical Dry Forest (TDF): very early, early, intermediate and late. This coefficient was calculated according to the equation: K = logB/LAI, where logB was determined by values of NDVI (Normalized-Difference Vegetation Index) and EVI2 (Enhanced Vegetation Index) in different phenological phases of vegetation; and LAI (Leaf Area Index) was determined by the average of LAI at different phases of leaf development. The spectral indices (NDVI and EVI2) were derived from solar and photosynthetically active radiations measured by meteorological sensors. The LAI was obtained by using hemispherical photographs. Once the K coefficient is determined it can be applied to the equation: LAI= K*logB. Due to TDF seasonality, the LAI, NDVI and EVI2 varied significantly throughout the rainy season. The measured indices varied significantly between successional stages, indicating sensitivity to structural differences during forest regeneration. Due to variations during the leaf development in TDF, we also determined ΔK (leaf growth phase) and Kmax (leaves fully expanded). Furthermore, the K values differed between succession stages. Thus, we established a model based on spectral properties of vegetation coupled with biophysical characteristics in a TDF that makes possible to estimate LAI. The application of the K coefficient can improve remote estimations of forest primary productivity and gases and energy exchanges between vegetation and atmosphere. Lattes PDF BibTeX

    Abstract Os padrões de distribuição dos insetos galhadores nas plantas hospedeiras são fortemente dependentes da fenologia das mesmas. Este processo pode afetar a quantidade de recurso disponível tanto para o crescimento reprodutivo quanto para o vegetativo. Desse modo, a quantidade e a qualidade dos recursos alimentares determinam a ocorrência dos insetos galhadores. A espécie Copaifera langsdorffii (pau d’óleo) (FABACEAE), possui a mais rica fauna de insetos galhadores descrita para a região Neotropical, no entanto a relação da sincronização dos galhadores com a fenologia desta planta ainda não é bem conhecida. Diante disso, foi realizado um estudo em um fragmento de Cerrado sentido restrito, saída norte da cidade de Montes Claros – MG, para avaliar como a variação fenológica afeta a diversidade de insetos galhadores associados. Foram monitorados a cada dois dias, de agosto de 2012 a maio de 2013, 109 indivíduos de C. langsdorffii. Os indivíduos da população estudada apresentaram uma variação de 67 dias no tempo de brotamento, sugerindo assim uma variação fenológica assincrônica, padrão que pode estar relacionado com a variação climática local ou às diferenças no método de caracterização da fenologia das plantas em campo. Observou- se também que o tempo de brotamento afeta a biomassa de folíolos, o número de folíolos e o comprimento dos ramos e não afeta o desenvolvimento vegetativo e a produção de fenóis totais. A riqueza de galhas foi afetada pelo tempo de brotamento das plantas e a abundância de galhas foi afetada pelo tempo de brotamento, pela fenologia, pelo comprimento dos ramos e pelo número de folíolos. Os insetos galhadores sincronizaram sua emergência com o aparecimento dos órgãos alvo (folhas novas) das hospedeiras.

    	abstract = "Os padrões de distribuição dos insetos galhadores nas plantas hospedeiras são fortemente dependentes da fenologia das mesmas. Este processo pode afetar a quantidade de recurso disponível tanto para o crescimento reprodutivo quanto para o vegetativo. Desse modo, a quantidade e a qualidade dos recursos alimentares determinam a ocorrência dos insetos galhadores. A espécie Copaifera langsdorffii (pau d’óleo) (FABACEAE), possui a mais rica fauna de insetos galhadores descrita para a região Neotropical, no entanto a relação da sincronização dos galhadores com a fenologia desta planta ainda não é bem conhecida. Diante disso, foi realizado um estudo em um fragmento de Cerrado sentido restrito, saída norte da cidade de Montes Claros – MG, para avaliar como a variação fenológica afeta a diversidade de insetos galhadores associados. Foram monitorados a cada dois dias, de agosto de 2012 a maio de 2013, 109 indivíduos de C. langsdorffii. Os indivíduos da população estudada apresentaram uma variação de 67 dias no tempo de brotamento, sugerindo assim uma variação fenológica assincrônica, padrão que pode estar relacionado com a variação climática local ou às diferenças no método de caracterização da fenologia das plantas em campo. Observou- se também que o tempo de brotamento afeta a biomassa de folíolos, o número de folíolos e o comprimento dos ramos e não afeta o desenvolvimento vegetativo e a produção de fenóis totais. A riqueza de galhas foi afetada pelo tempo de brotamento das plantas e a abundância de galhas foi afetada pelo tempo de brotamento, pela fenologia, pelo comprimento dos ramos e pelo número de folíolos. Os insetos galhadores sincronizaram sua emergência com o aparecimento dos órgãos alvo (folhas novas) das hospedeiras. Sendo assim, insetos galhadores associados são influenciados pela fenologia, justificando a maior abundância e riqueza de galhas em plantas com brotação precoce.",

    Abstract Este estudo propôs verificar a atividade larvicida em larvas de 3° instar de Aedes aegypti (Díptera: Culicidae) das substâncias tóxicas extraídas do extrato aquoso da “torta de mamona”, um subproduto da cadeia de biodiesel. A utilização de óleos vegetais como combustível (biodiesel) tem se mostrado uma alternativa viável aos combustíveis fósseis, especialmente por serem biodegradáveis não tóxicos e com baixos perfis de emissões. A mamona possui especial interesse para o semiárido, por crescer espontaneamente em toda região, a sua semente é rica em ricina substância com conhecido efeito inseticida. Os bioensaios com o extrato aquoso da “torta de mamona” foram realizados com 40 larvas/grupo, perfazendo um total de 120 larvas por tratamento (concentrações) incluindo grupo controle. A aplicação do extrato foi feita no meio de desenvolvimento e criação das larvas, acrescida de dieta larval e mantidas em câmaras incubadoras com temperatura e umidade constantes. Os resultados mostraram que o extrato aquoso da “torta de mamona”, interferiu sobre o ciclo de desenvolvimento do mosquito marcando sua eficiência pelo efeito tóxico com 100% de mortalidade larval, nas concentrações ≥ 40% em um tempo mínimo de três horas e máximo de cinco horas. E, a mesma nos teste de degradação apresentou atividade larvicida por até 72 horas (três dias) no qual inicia seu processo de degradação, demonstrando um baixo poder residual ao ambiente. Dessa forma, o extrato aquoso da “Torta de Mamona” mostrou-se como um potente biolarvicida de origem natural de rápida ação e de baixo poder residual no controle do A. aegypti, principal mosquito transmissor da dengue e da febre amarela urbana.

    Abstract Flies from the family Streblidae and Nycteribiidae are specialized ectoparasites in the parasitic habit of bats, which can be influenced by factors related to their host environment. In Tropical Dry Forest (TDF) studies of these flies have not been realized. The TDF are highly seasonal environments and are distributed in the form of mosaic across Brazil. Due to the intensive use of the land by human activities, these environments are at different stages of ecological succession. In this work parasitological aspects (community composition, prevalence, mean intensity of infestation and specificity) in the interaction bat flies-bats in three areas of Brazilian TDF were studied. Furthermore, we tested the hypothesis that seasonality and ecological succession influence the parasitism of Artibeus planirostris, most abundant species in the study, in these environments. The associations found here are common to Brazil, though some are new records for the region. Most flies were considered highly specific, reinforcing that these ectoparasites have low ability to survive on hosts that are not usual. Therefore, dispersal barriers have a strong pressure in this host-parasite interaction. As for seasonality and ecological succession, we found no significant effect on parasitism of A. planirostris. Being that, aspects like shelter and feeding plasticity of host, and specificity parasite, may be responsible for this result. Lattes PDF BibTeX

    Abstract This study evaluated the survival and growth of saplings of native species implanted in a stretch of swamp forest in the peat swamp of the Acari (Chapada Gaúcha, MG, Brasil) under different water conditions (CH1 - dry and soggy, CH2 - intermittent flooding, CH3 - permanent flooding). The study area was surrounded and isolated from cattle where 7604 seedlings were inserted in 16 plots of 80 m × 40 m, with watercourse located on the parcel. The planted individuals were characterized according to their guild regeneration and diameter at ground height and sapling height and water depth, quarterly until 15 months after planting were measured. The survival and growth of saplings were smaller where the flooding was permanent, but each species had different adaptations regarding diferentes water conditions. Cecropia Pachystachya, Calophyllum brasiliense, Myrsine umbellata and Mauritia flexuosa had higher survival and growth, featuring recommendable for environmental restoration of this environment. Survival was greater in light demanding species and pioneer, and growth in shade-tolerant.

    Abstract (Flora e estrutura do estrato regenerante de florestas higrófilas em sistemas de veredas com 9 diferentes impactos antrópicos no norte de Minas Gerais). Muitos fatores são responsáveis pela 10 estrutura e distribuição das comunidades vegetais. As ilhas de florestas higrófilas em veredas são 11 um tipo vegetacional que se encontra distribuída em manchas e são peculiares devido ao estresse 12 hídrico. O objetivo deste trabalho foi verificar quais as semelhanças florísticas e estruturais do 13 estrato regenerante entre seis florestas higrófilas em veredas com diferentes impactos antrópicos, 14 além de relacionar variáveis edáficas com a composição florística. Este estudo foi desenvolvido na 15 Área de Proteção Ambiental do Rio Pandeiros, norte de Minas Gerais. Foram amostrados todos os 16 indivíduos regenerantes arbustivo-arbóreos com tamanho 1 cm de diâmetro a altura do solo e <3 17 cm de diâmetro a altura do peito (1,30 m do solo) em 100 parcelas de 25 m 2 em cada área. Foi 18 coletado o solo de 100 parcelas de 100 m 2 , que englobavam as parcelas de 25 m 2 . No total das seis 19 áreas, foram amostrados 5442 indivíduos, distribuídos em 134 espécies, 85 gêneros e 47 famílias, 20 com diversidade de 3,38 (Shannon) e equabilidade de 0,69 (Pielou). As ilhas se separaram em áreas 21 preservadas, onde se destacaram espécies características de áreas alagadas, e perturbadas, com 22 destaque para espécies de ambientes mais secos. A similaridade entre as áreas foi baixa, com apenas 23 duas espécies em comuns, e a relação das espécies com as variáveis do solo mostrou que os 24 nutrientes Ca, K e Mg, e opHcorrelacionaram com a área mais preservada, enquanto o Al teve 25 maior relação com as áreas mais perturbadas. A distribuição das espécies regenerantes nas ilhas de 26 florestas higrófilas apresentou correlação com as variáveis edáficas e com o estado de degradação 27 encontrado em cada área,sugerindo que o histórico e a intensidade de perturbação estão 28 modificando o ambiente e interferindo na estrutura e na composição dos indivíduos regenerantes da 29 floresta.

    Abstract Studies in altitudinal gradients indicate a negative relationship between species richness and increasing altitude. This pattern is a reflection of abio tic and biotic changes along the altitudinal variation. Our aim was to evaluate the effect of altitude on the diversity of herbivorous insects associated to a bush on different spatial scales (α, β and γ) and test the following hypotheses: i. The diversity of differentiation in higher spatial scale (between altitudes - β 3 ) is the hierarchical component that contributes most to the total diversity of the guilds of chewing and sucking insect herbivores; ii. the composition of chewing and sucking herbivorous insects changes along the altitudinal gradient; and iii. alpha diversity (richness per plant), the abundance, and the beta diversity (β) of chewing and sucking insect herbivores decreases with increasing altitude. To test our hypotheses nine sites of Baccharis dracunculifolia were selected at three altitudes (800 m, 1100, and 1300m a.s.l.). The free-living insects herbivores were captured using the technique of beat using entomological umbrella. We found that β3 was the component that contributed most to the y axis for chewing and sucking insects. The composition was different between the altitudes for both sucking and chewing insects. A higher richness and abundance of chewing and sucking insects were at 1300m 1100m a.s.l.. The greater heterogeneity for the chewing insects communities was at 800m a.s.l. (beta diversity) but there was no differences between altitudes for the sucking insects. The first and second hypothesis was corroborated, probably due to climate changes together with the changes in vegetation structure along the gradient. The presence of B. dracunculifolia at all altitudes and the lower diversity of other shrubs may have been responsible for changes in the pattern of decline species richness, found in altitudinal gradients, in previous studies on the same site. The greater complexity of the vegetation at 800m and 1100m altitude may have been responsible for the greater heterogeneity of chewing insects found in plants (β). The greatest richness of sucking insects in the intermediate altitude (1100m) is probably due to the increase in accumulated net primary production, providing optimal amount of resources. The presence of the resource along the altitudinal gradient determines a distinct pattern in the different guilds. Lattes PDF BibTeX

    Abstract Leaf characteristics are often cited as key indicators of the relationship between resource use by plants , investment in biomass and ecosystem functioning , because they are easily quantifiable and are strongly related to the physiology of plants. The Tropical Dry Forests are still few studied and the optical properties of species at this environment. The presence of successional stages in TDFs may cause the process of selecting traits and environmental filtering in species existing on a local scale. The aim of this study was to evaluate the phenotypic plasticity in leaf traits and their influence on the pattern of herbivory and leaf reflectance in three species distributed along a successional gradient in a FTS in northern Minas Gerais, Brazil. Was studied: Poincianella pluviosa, present in all successional stages, early, intermediate and late; Handroanthus ochraceus present only in the first two of stages and Handroanthus reticulatus present exclusively in the last two. We evaluated the contents of chlorophyll a, b, total, carotenoids and water as well as the percentage of leaf area damaged, sclerophylly and spectral reflectance indices mND705, mSR705 and WI. The results showed that there are traces of phenotypic plasticity among species mainly in regards to the physiological characteristics of this forest. The contents of pigments except carotenoids were well correlated with leaf indices. Herbivory and WI index was not influenced by any of the evaluated components and water content respectively.

    Abstract The main goal in ecology is to understand the diverse factors that can influence the distribution patterns of diversity and the dynamics of organisms, as well as the mechanisms that determine them. Some of these factors are forest fragmentation, environmental heterogeneity, rainfall and soil physical factors. The Tropical Dry Forest (TDFs) shows the highest annual rate deforestation between rainforest. Despite of the intensification conservation efforts, there is still very large gap knowledge about these plant formations and the relation with the fauna groups present there. Beetles of the subfamily Scarabaeinae (Coleoptera: Scarabaeidae) are important elements on nutrient cycling, in soil aeration, as secondary seed dispersers and reducing parasites present in feces of mammals. This study had the objective to explore some of the different factors that can determine the diversity of Scarabaeinae in TDFs for that were tested: i: hypothesis of habitat heterogeneity, Influence of soil granulometry on the community of beetles and iii. Season effect on the diversity of dung-beetles. This study was conducted at the Parque Estadual da Lagoa do Cajueiro, in Matias Cardoso city, Serra do Cipó, located in Santana do Riacho. We collected 15.408 individuals, belonging to 57 species. Through building generalized linear models (GLMs) using pseudoreplication space-temporal it was observed that there was no relation between the diversity of beetles with heterogeneity of habitat and soil texture, in contrast, there was significant difference between areas of collects and season.

    Abstract The aim of this study was compare the leaf damage caused by herbivores over a successional gradient in a tropical dry forest, relating this with sclerophyly, chemical defensive compounds, nutritional content and habitat structural complexity. Data of leaf damage, nitrogen content, phenolic compounds, tanins, sclerophylly and ambient complexity were take over three successional stages (early, intermediate and late). The samples were conducted in April-May of 2011 in 15 plots of 50 x 20 m each, located in three conservation units in north of Minas Gerais, Brazil. In each plot, the five most abundant plant species were selected and marked up to five individuals per specie. In each one, 20 leaves were collected randomly to make physicochemical analyses. Plots of early successional stages showed lowest values for height, density and holdridge complexity indices (HCI), compared with intermediate and late areas. In general way, the percentage of leaf area damage (2.5 - 4.2%), was lower than the observed in other studies in FTS areas, probably due the high concentration of defensive compounds or lower herbivores pressure in this ambient. Regarding defensive characteristics, specific leaf mass (SLM) varied along succession, decreasing gradually along stages, probably due the higher radiation observed in early areas. Levels of phenolic compounds were higher in late areas, and did not vary between early and intermediate stages. Tanins did not vary along successional stages, but showed negative relationship with herbivore. In another hand, HCI was positively related with herbivore and negatively with phenolic compounds concentration and SLM, probably due the high abundance of herbivores insects in late areas. Studies that investigate the relationship between habitat complexity and leaf features are needed to better understand ecological patterns in tropical dry forests. Lattes PDF BibTeX

    Abstract Rhizobacteria promoting growth of plants (RPGPs) bacteria are able to colonize the roots, stimulating them directly or benefiting growth and development of plants. Although recent studies report their uses in Brazil, few studies assess the natural presence of these bacterial species in the soil. The aim of this study was to test the following hypotheses: 1) The rhizobacteria richness, abundance, IAA production, phosphate solubilization and nitrogen fixation increases during the wet season and decreases during the dry season. 2) The rhizobacteria richness, abundance, IAA production, phosphate solubilization and nitrogen fixation is higher in intermediate stages of succession. Furthermore, this study aimed to do the characterize morphological and biochemical of the rhizobacterias. For this, the study was conducted in three protected areas (PAs) in the north of Minas Gerais: in the Reserva Biológica do Jaíba, Parque Estadual Lagoa do Cajueiro e na Reserva Biológica Serra Azul, located in the municipalities of Matias Cardoso and Jaíba in valley middle São Francisco river. The bacterias were classified according to morphology and were performed tests of Gram, catalase, production of indole-3-acetic acid (IAA), phosphate solubilization and nitrogen fixation (BNF). In addition, were performed the analyzes of the properties physical and chemical of the soils. Statistical analyzes were performed in statistical software R. We obtained a total of 826 isolates, of which 441 are from the collection of the wet season and 385 are from collection of the dry season. 9 morphospecies were sampled for the collections of the wet season and dry season. Since 7 morphospecies(Mofo1, Morfo3, Morfo4, Morfo5, Morfo6 and Morfo7) are shared between the wet season and the dry season and two morphospecies (Morfo8 and Morfo9) that occurred only in samples collected from the wet season. According to the analyzes, the station affected the richness and abundance of rhizobacteria. In contrast, the stage did not affect significantly the richness and abundance. Most isolates were positive for Gram, catalase, IAA production and nitrogen fixation. However, few isolates solubilized phosphate. In the analysis of the composition of morphospecies, when analyzing only the wet and dry season, the NMDS showed the formation of two groups, indicating that there are differences in the composition of morphospecies rhizobacteria between stations indicated by ANOVA. However, between stages in both the wet season and in the dry season did not separate any group. In the analysis of the two CCA ordination axes explain 88% of the total variance. Since the variables of aluminum saturation (m), Silt, aluminum (Al), Potassium (K) and Clay relate positively with axis 1. While the thick sand and phosphorus (Prem) relate positively with axis 2.

    Abstract Once the communities of mycorrhizal fungi may be influenced by soil and seasonal factors, approaches that try to find consistent environmental patterns and aimed at understanding the structure and diversity of communities of these fungi associated with different environments and plants are still incompletely understood, the present study aimed to identify and assess the composition and distribution of arbuscular mycorrhizal fungi present in the rhizosphere of three different Macaúba populations of North of Minas Gerais, relating them to the soil and seasonal factors characterized. The study was conducted in three Macaúba populations of North of Minas Gerais: Brasilia de Minas, Claro dos Poções and Cristália, which was carried out by sampling soil Macaúba in 10 groups, each group consisting of three individuals of this species during the dry season and wet season. The soil samples generated were carried to the laboratory for extraction, counting and identification of spores and physicochemical characterization. The Macaúba populations of North of Minas Gerais presented a potential inoculum of AMF and were dominated by families Acaulosporaceae and Glomeraceae, and the most representative species for each of these families were Acaulospora scrobiculata and Glomus glomerulatum. The seasonal influence on the occurrence of AMF species unique to the dry season and the rainy season and influenced the richness and abundance of AMF, with higher values during the dry season. Among various soil attributes evaluated, the clay content was found as the factor that influenced at a lower richness and abundance of these fungi in Macaúba populations studied. There was no influence of soil factors and seasonality in the 9composition and spatial distribution of the AMF, possibly by populations Macaúba have filed similar environmental conditions. Positive effects of calcium, phosphorus and coarse sand were observed on the abundance and richness of AMF evaluated. The fine sand showed varying patterns, which negatively affected the abundance and richness positively. We emphasize the importance of further studies to physical factors of soil, with respect to texture, since we found an important influencer in the occurrence of AMF and few studies address relevance.

    Abstract The Tropical Dry Forests are biomes dominated by deciduous plant species, widely distributed in the South American continent. In them, the seasonal, the successional stages, beyond the soil physical-chemicals properties influence their structure and function and, therefore, the microbial diversity of the soil can be changed. In this context, the Growth Promoting Rhizobacteria in Plants are interesting targets of study. The aim of this study was to test the following hypotheses: richness, abundance and bacterial biochemical activity are influenced by the station; and richness, abundance and bacterial biochemical activity are influenced by successional stages of regeneration. For this, bacteria isolated from soil were characterized morphologically and biochemically. The production of indole-3-acetic acid, phosphate solubilization and Biological Fixation of Nitrogen has been verified. The Variables richness and abundance responded the first hypothesis tested, since were higher during the rainy season. The richness and abundance did not vary along of the successional gradient. The variable indole-3-acetic acid, the phosphate solubilization and Biological Fixation of Nitrogen did not correspond to the hypotheses tested. The morphology, Gram and catalase show that the strains have characteristics very similar. These isolates must be submitted to molecular techniques to be identified phylogenetically.

    Abstract The aim of the study was to evaluate the effect of secondary succession and change between wet and dry season in the community structure of mosquitoes of a Deciduous Forest in northern of Minas Gerais. We tested the following hypotheses: i. Secondary succession occurs that causes a change in the composition, richness and abundance of mosquitoes ii. richness, abundance and community composition alter mosquitoes in dry and rainy seasons. The study was conducted in the State Park Lagoa do Cajueiro (PELC), located in the Valley of the Middle São Francisco, in the northern state of Minas Gerais. The local vegetation is characterized by the large volume of leaves felt in the dry season (90-95%), however, three months in this age doesn’t occur rain precipitation . Mosquitoes were colected during the rainy season (February 2012) and dry season (July 2012), at different stages of secondary succession, named; early, intermediate and late. We used three different types of methodology: collection with a Shannon trap, where mosquitoes were collected with the portable sucker machines during and after sunset; CDC light trap was baited with octenol and CO 2 . They were exposed in specific areas during 24 hours. Finally was collected mosquitoes that landed on the researchers in field. As a result it was observed significants difference in the abundance and richness of mosquitoes between stages of secondary succession, that was not observed for the composition. Was observed significant differences in the abundance, richness and species composition of mosquitoes, between the dry and rainy seasons. Our work showed that sites with a high destruction enviromental caused by human intervention, get a rise of the abundance and richness of mosquitoes, that can transmit diseases. In preservated locals these paramaters weren’t observed, this way, we could observe the impotance of the studies of the Culicidae family to enviromental conservation. Lattes PDF BibTeX

    	abstract = "The aim of the study was to evaluate the effect of secondary succession and change between wet and dry season in the community structure of mosquitoes of a Deciduous Forest in northern of Minas Gerais. We tested the following hypotheses: i. Secondary succession occurs that causes a change in the composition, richness and abundance of mosquitoes ii. richness, abundance and community composition alter mosquitoes in dry and rainy seasons. The study was conducted in the State Park Lagoa do Cajueiro (PELC), located in the Valley of the Middle São Francisco, in the northern state of Minas Gerais. The local vegetation is characterized by the large volume of leaves felt in the dry season (90-95%), however, three months in this age doesn’t occur rain precipitation . Mosquitoes were colected during the rainy season (February 2012) and dry season (July 2012), at different stages of secondary succession, named; early, intermediate and late. We used three different types of methodology: collection with a Shannon trap, where mosquitoes were collected with the portable sucker machines during and after sunset; CDC light trap was baited with octenol and CO 2 . They were exposed in specific areas during 24 hours. Finally was collected mosquitoes that landed on the researchers in field. As a result it was observed significants difference in the abundance and richness of mosquitoes between stages of secondary succession, that was not observed for the composition. Was observed significant differences in the abundance, richness and species composition of mosquitoes, between the dry and rainy seasons. Our work showed that sites with a high destruction enviromental caused by human intervention, get a rise of the abundance and richness of mosquitoes, that can transmit diseases. In preservated locals these paramaters weren’t observed, this way, we could observe the impotance of the studies of the Culicidae family to enviromental conservation.",

    Abstract The creation of units of conservation (CUs) has been consolidated as one of the most common strategies for biodiversity conservation and reduction of anthropogenic pressures on natural resources. However, the process of CU creation is very complex and CU effectiveness is controversial, due to the criteria for choosing the areas to be protected and their further management. The present study aimed to conduct a case study on the impact of the creation of CUs to avoid deforestation using Matching methods, focusing on the north of the Minas Gerais state, Southeastern Brazil. For this purpose, we selected five CUs of restricted use with more than 10 years since creation. Using methods of Geographic Information System, we randomly distributed 3 ha plots across the study region. After a filtering process, the avoided deforestation in plots inside and outside CUs were compared using Matching analysis for the periods between 1986-1996 (before UCs creation) and 1996-2010 (after UCs creation). Land cover at each period was determined from the analyses of Landsat – 5 (TM) imagery. In general, our results indicate that the five CUs created in the north of Minas Gerais in the 1990s were effective in reducing deforestation within the CUs, though avoided deforestation rates have been relatively low (2.5% in 14 years from 1996 to 2010). Geographical location was a key factor for CUs effectiveness, such that plots inside CUs in plain slope or close to large cities and roads had a greater impact on avoided deforestation. The results of this study corroborate a global trend of establishment of CUs in remote areas with low market value, thus reserving areas of high agricultural suitability or areas close to consumer markets to economic activities. The evaluation of CU effectiveness using Matching methods should be employed in a broader scale, to subsidize conservation policies in Brazil and elsewhere in the world. Lattes PDF BibTeX

    Abstract This study aimed to test the following hypotheses in tropical dry forests (TDFs) inserted in three vegetation domains (Brazilian savanna, Brazilian savanna-Caatinga transition and Caatinga): i. the insect herbivores community differs among the TDFs evaluated; ii. the abundance and species richness of insect herbivores are positively related with height, richness and density of trees in TDFs; iii. the local diversity (α) and the differentiation diversity between TDFs (β 3 ) are the hierarchical components which most contribute to the regional diversity of insect herbivores (γ); iv. the tree richness has a positive effect on the differentiation diversity of insect herbivores between trees (β 1 ). The richness and abundance of insect herbivores (chewing and sap-sucking) as well as height, richness and density of plants was estimated in each TDF. Sampling of insect herbivores associated to the canopy of trees was carried in the end of wet season. Insect herbivores community differed among TDFs, probably reflecting the floristic and structural modifications caused by the influence of different domains in each TDF. A positive effect of height and richness of tree was observed on the richness and abundance of chewing and sap-sucking herbivores, however the positive effect of density of trees was observed only for sap-sucking herbivores. The increase of structural complexity with the increment of height and richness of trees in forests promotes the coexistence of a greater number of insect herbivores species. However, the lower feeding specialization of chewing herbivores in relate to the sap-sucking possibly determined the lack of tree density effect on richness and abundance of those insects. Additive diversity partitioning of insect herbivores showed an important contribution of differentiation diversity between TDFs (β 3 ) for regional diversity of herbivores. The differentiation diversity of insect herbivores between trees (β 1 ) was positively affected by tree richness, corroborating the importance of plant richness on insect herbivores diversity associated in a forest. The implications of this study vary from the need to conserve TDFs in distinct vegetation domains until the need to employ approaches as such as those used in this study to other biological groups, in order to determine general patterns of diversity and to become effective future efforts to maintain the diversity in TDFs.

    Abstract {Attalea vitrivir (synonym: Orbignya oleifera) is one of six species of palm, Arecaceae family, popularly known as "babassu". This species has been explored in cosmetics, food and is also used for the production of detergents and oils, due to the high oil content in the seeds. It is currently distributed in fragments located between the southern Bahia and center-north of Minas Gerais. This fragmentation has no effect on ecological processes, and also genetic. This study aimed to evaluate the genetic diversity and structure of populations in six areas of A. vitrivir divided into two regions (north and south), so as to promote a greater understanding of the factors that operate in the distribution and partitioning of diversity.

    Abstract The objective of this work was: I, find variations in birds' composition and diversity in three areas of Seasonally Dry Tropical Forests (SDTFs) in different special e temporal scales; II, analyze if the distribution pattern’ plant and birds between STDFs are similar; III, evaluate the influence of structural heterogeneity on birds’ richness and abundance between SDTFs. The birds were sampled in 2012 in three areas of SDTFs, Parque Estadual Lagoa do Cajueiro (PELC) and Parque Estadual da Mata Seca (PEMS), both in a northern region of Minas Gerais state, and in Santana do Riacho (SRMG), in the central region of this state. The avifauna data were obtained with point counts methodology. The differences of birds’ richness and abundance between different SDTFs, and between wet and dry season, was verified using generalized linear models (GLMs). To verify differences in birds' composition between three areas and also between two seasons, was used non-metric multidimensional scaling analysis (NMDS) and Tukey test. For a verify if the pattern of plants composition is similar of the birds composition, were used Pianka's overlap index. The positive correlation between structural heterogeneity and species richness was verify using generalized linear mixed models (GLMERs). The result of GLMs showed significant differences between all SDTFs, except in the relationship between PEMS and PELC. About the abundance, all areas showed significant differences. The NMDS pointed differences in the bird communities structure between the SDTFs, in which was observed that a relationships between PELC and PEMS showed more greater similarity in the birds composition than all other. For Tukey test, the result was the same observed in the NMDS. For seasonal variations, the NMDS indicate what birds' composition did not show significant differences only in the SRMG, in which there was not significant change in the structure. The largest similarity in birds composition was observed between PELC and PEMS and also the greater richness and abundance of birds, may be due of historical and biogeography factor. The birds composition between seasons showed significant differences, these may be understood by structural changes occurred in habitat between seasons, what further change in the habitat selection by birds. The plant composition showed the same pattern of similarity observed for the birds composition between the STDFs. The GLMERs didn’t show difference between birds diversity and measures of structural heterogeneity. Some explanations can be suggested: first, the small variation of some structural characteristics between sampled areas; second, in environments with lowest primary productivity, how the SDTFs, a energetic concentration is one factor that more influence the species diversity; third, the structural measures used in this work may not be so important in structuring the bird community. In summary, there was variation in richness, abundance and composition at different scales, in which biogeographical and ecological factors are probably the main responsible for these variations. The structural heterogeneity do not corroborate, because habitat more heterogeneous do not has higher species richness. Thus, this study showed the importance of study in different scales to better understand the diversity and distribution of species in the environment. Lattes PDF BibTeX

The antioxidant activity was evaluated through the reduction of the DPPH radical. The phenolic compounds contents were determinate for Follin-Ciocalteau method. The antimicrobial activity was evaluate against standard strains of Aeromonas hydrophila, Entercoccus faecalis, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus using the broth microdilution method. The chemical composition was analyzed using GC-MS. The extracts showed high antioxidant capacity, showing low values of EC 50 , some lower than rutina. There are negative correlation between phenolic total contents and antioxidant activity in fractionated extracts. The most polar solvents recovered higher phenolics compounds contents and antioxidant activity. The Gram-positive bacteria were more susceptible and the most interesting result was value of MIC and MBC (125μg.mL -1 , de 625μg.mL -1 ) of the L. molleoides’ butanolic extract against S. aureus. On the extracts was found as major compounds gallic acid, ethylgallic acid, catechin, epicatehin and fat acids hexadecanoic acid, and octadecanoic acid.

  62. Fernanda Silva Monção. Composição e estrutura da comunidade de macroinvertebrados associados a macrófitas aquáticas em um córrego da cadeia do Espinhaço. Anderson Medeiros dos Santos, UNIMONTES, 2013.
    Abstract The distribution pattern of aquatic organisms in lotic ecosystems can be determined by several factors like the current velocity, temperature of the water, substrate, dissolved oxygen and interaction with other organisms. With the aim to evaluate the composition and structure of community macroinvertebrate associated with macrophytes, in a stretch of Córrego das Éguas, (MG), were sampled monthly for 12 months. Selected five stands heterogeneous composed of two aquatic macrophytes with different architectural patterns, Diamantina lombardii (Podostemaceae) and Eriocaulon aquatile (Eriocaulaceae). In each of these stands was removed 1 square in the center of 100cm2 and 1 on the edge with the aid of the collector type "Surber". Measures depth and current velocity at the center and at the edge of each stand were carried. Macrophytes were washed, identified and dried in greenhouse at 70°. After washing the macrophytes , the associated macroinvertebrates were separated and identified the lowest possible taxonomic level and classified as trophic functional group (TFG) according to appropriate literature. Sampled 57.535 macroinvertebrates, distributed into 68 taxa and in five trophic functional group. Of these 34.237 were found in the center of stands and 23.298 on the edge. When compared the density of macroinvertebrates between the center and edge, was observed significant difference, well as taxa richness. As to TFG, just density of filterers collectors was different. Between the dry and rainy seasons, both taxa richness, as the abundance of macroinvertebrates were higher in the dry. When compared length (cm) of larvaes between the center and the edge, it was observed that there is a significant difference in size for all instars. The larvae located in the center of the stand are larger than those found on the edge. The biomass of macroinvertebrates was also significantly different between the center and the edge of stands. When evaluating the influence of the current can be observed that the taxa richness and density of macroinvertebrates were negatively influenced. However only the taxa richness of scrapers and gathering collectors were influenced, and this influence was negative . The occurrence and abundance of taxa varied among the months sampled, but no difference was found between the center and edge of the stands. The present study showed that the edge effects have a large influence on macroinvertebrates associated with aquatic macrophytes, as well as the type of substrate showed large importance on the structuring of macroinvertebrate community. The current 9velocity influences negatively the abundance and richness of macroinvertebrates. Inside stands of aquatic macrophytes there is larger abundance, size and biomass of macroinvertebrates than the edges. However, the composition and richness of rate did not differ between center and edge. Furthermore, the composition, richness and abundance of macroinvertebrates vary according to seasonal changes. Among the factors analyzed, edge effects were the factors most influenced. Lattes PDF BibTeX

    	abstract = {The distribution pattern of aquatic organisms in lotic ecosystems can be determined by several factors like the current velocity, temperature of the water, substrate, dissolved oxygen and interaction with other organisms. With the aim to evaluate the composition and structure of community macroinvertebrate associated with macrophytes, in a stretch of Córrego das Éguas, (MG), were sampled monthly for 12 months. Selected five stands heterogeneous composed of two aquatic macrophytes with different architectural patterns, Diamantina lombardii (Podostemaceae) and Eriocaulon aquatile (Eriocaulaceae). In each of these stands was removed 1 square in the center of 100cm2 and 1 on the edge with the aid of the collector type "Surber". Measures depth and current velocity at the center and at the edge of each stand were carried. Macrophytes were washed, identified and dried in greenhouse at 70°. After washing the macrophytes , the associated macroinvertebrates were separated and identified the lowest possible taxonomic level and classified as trophic functional group (TFG) according to appropriate literature. Sampled 57.535 macroinvertebrates, distributed into 68 taxa and in five trophic functional group. Of these 34.237 were found in the center of stands and 23.298 on the edge. When compared the density of macroinvertebrates between the center and edge, was observed significant difference, well as taxa richness. As to TFG, just density of filterers collectors was different. Between the dry and rainy seasons, both taxa richness, as the abundance of macroinvertebrates were higher in the dry. When compared length (cm) of larvaes between the center and the edge, it was observed that there is a significant difference in size for all instars. The larvae located in the center of the stand are larger than those found on the edge. The biomass of macroinvertebrates was also significantly different between the center and the edge of stands. When evaluating the influence of the current can be observed that the taxa richness and density of macroinvertebrates were negatively influenced. However only the taxa richness of scrapers and gathering collectors were influenced, and this influence was negative . The occurrence and abundance of taxa varied among the months sampled, but no difference was found between the center and edge of the stands. The present study showed that the edge effects have a large influence on macroinvertebrates associated with aquatic macrophytes, as well as the type of substrate showed large importance on the structuring of macroinvertebrate community. The current 9velocity influences negatively the abundance and richness of macroinvertebrates. Inside stands of aquatic macrophytes there is larger abundance, size and biomass of macroinvertebrates than the edges. However, the composition and richness of rate did not differ between center and edge. Furthermore, the composition, richness and abundance of macroinvertebrates vary according to seasonal changes. Among the factors analyzed, edge effects were the factors most influenced.},

  63. Diellen Librelon Silva. Aspectos fenológicos de Acrocomia aculeata (Jacq.) Lodd. ex Mart. (Arecaceae) em populações no Norte de Minas Gerais-Brasil. Yule Roberta Ferreira Nunes, UNIMONTES, 2013.
    Abstract A fenologia estuda o comportamento dos vegetais em correlação ao meio ao qual se encontram, abrangendo os padrões estacionais de floração, frutificação e folhação (RUIZ e ALENCAR, 2004). Segundo Bencke e Morellato (2002), os ciclos fenológicos de plantas tropicais são complexos e sujeitos a vários fatores internos e externos (MANTOVANI et al., 2003; LOCATELLI e MACAHADO, 2004). Entretanto, o principal foco da maioria dos estudos fenológicos tem sido realizado a respeito de fatores externos, que funcionam como sinal para os fatores endógenos das plantas e que acionam as fenofases (DIAS e OLIVEIRA-FILHO, 1996). Fatores externos, também chamados de fatores proximais, como o clima, estão relacionados com o início e a duração das alterações visíveis no ciclo de vida das plantas. Assim, a precipitação, a temperatura, o fotoperíodo, a intensidade de radiação e a qualidade do solo encontram- se diretamente relacionados com as épocas de floração, frutificação, queda e brotamento foliar (PEDRONI et al., 2002). Em regiões com forte estacionalidade climática, as fenofases são influenciadas pelas alterações periódicas de disponibilidade de água, e até mesmo, pequenas alterações no comprimento do dia ou no decorrer do ano, podem ter efeitos sobre os processos de desenvolvimento da planta (LARCHER, 2000). Além disso, as plantas também estão sujeitas as variações edáficas de uma região (FOURNIER, 1974). A quantidade de nutrientes disponível no solo pode afetar o ciclo reprodutivo das plantas (ZAGT 1997) e, em muitas vezes, a acentuada deficiência de recursos pode causar um padrão supra-anual de frutificação (FLOWERDEW e GARDNER, 1978). Os eventos fenológicos, quando ocorrem de forma sazonal e sincronizada, representam vantagens adaptativas para muitas espécies tropicais (PEDRONI et al. 2002). O sincronismo de uma população acontece quando uma proporção de indivíduosmanifesta um determinado evento fenológico simultaneamente, ou seja, quanto mais indivíduos apresentam as fenofases ao mesmo tempo, maior é sincronia da população. (BENCKE e MORELATO, 2002). Agentes sincronizadores como hidroperiodismo (disponibilidade de água), termoperiodismo (variação de temperatura) e fotoperiodismo (tamanho do dia) podem determinar o tempo, a duração e grau de sincronia das fenofases (PEDRONI et al., 2002). Já o assincronismo reflete a flexibilidade e adaptação dos indivíduos às condições adversas do ambiente, além de contribuir para a manutenção e expansão da população para outros locais. Segundo Grim e Mackey (2002), os fatores ambientais, os quais as plantas estão expostas, exercem forte influência na sua morfologia e fisiologia. Esse efeito fenotípico provocado pela a interação do indivíduo e o ambiente é chamado de plasticidade fenotípica (citação). Nas plantas, a plasticidade fenotípica pode ser expressa no crescimento em altura, na anatomia e morfologia das estruturas vegetativas e reprodutivas, na alocação de biomassa na taxa fotossintética, bem como, na fenologia (FUZETO e LOMÔNACO, 2000). Assim, as divergências fenotípicas geradas entre as populações podem gerar novas sub-espécies, raças ou ecótipos (SULTAN, 2000; CARDOSO e LOMÔNACO, 2003). Apesar de sua importância, estudos sobre estratégias fenológicos das espécies arbóreas nativas da flora do Cerrado são escassos, principalmente quando se considera a alta diversidade tropical (NUNES et al. 2005). Dessa forma, informações sobre os períodos de crescimento e reprodução e distribuição das plantas podem auxiliar projetos que visam o manejo da espécie principalmente quando se trata de espécies nativas que apresenta potencial para uso comercial como a Acrocomia aculeata (Jacq.) Lodd. ex Mart.(Figura 1).A B C Figura 1: Acrocomia aculeata (Jacq) Lodd. Ex Martius (Arecaceae): A - Planta; B - Inflorescência; C - Cachos com frutos maduros. (Fonte: a autora). Essa espécie é uma das inúmeras espécies nativas do cerrado, que apresentam grande potencial de utilização. No Estado de Minas Gerais, ocorrem grandes populações de macaúba, consideradas como economicamente promissoras (MOTTA et al., 2002). Essa palmeira é utilizada para diversos fins, principalmente como fonte de alimentos e artesanato, por moradores de comunidades tradicionais (LORENZI, 2006). No entanto, o recurso economicamente mais expressivo da macaúba é a extração de óleo vegetal para a produção de biodiesel e na indústria cosmética. De acordo com estimativas, a macaúba produz até quatro mil litros de óleo por hectare/ano (figura 2). Essa oleaginosa supera culturas anuais como soja (420L), girassol (890L) e a mamona (1.320L), (CESAR, 2003).A potencialidade econômica da macaúba esta aliada ao manejo sustentável, devido ao fato, dessa oleaginosa ser uma planta endêmica e perene, com benefícios para manejo e conservação do solo (MOTTA, 2002). A macaúba possui uma alta produtividade de matéria prima, necessita de pouca água e pouco trabalho manual na colheita dos frutos, com isso, evita o êxodo rural garantindo assim, emprego as populações em sua região de origem (SOUZA, 2012). 4.000 4000 3500 3000 2500 1.320 2000 890 1500 1000 420 500 Soja Girassol Mamona Macaúba Figura 2 : Comparação entre capacidade de produção de óleo vegetal de algumas (Produção de óleo: Litro/hectare/ano). (Adaptado de Souza, 2012) Assim, considerando a importância dos estudos fenológicos, associados à escassez de dados sobre a macaúba, nesse estudo procurou-se avaliar o comportamento fenológico intra e inter populacional em quatro populações de A. aculeta no norte de Minas Gerais, relacionando a ocorrência dos eventos fenológicos ao longo de quatro anos, com fatores ambientais.

  64. Anielle Cristina Fonseca Pereira. Fatores que regulam a predação por bruchinae (Coleoptera, Chrysomelidae) em Acrocomia aculeata (Jacq.) Lodd. ex. Martius (Arecaceae). Maurício Lopes de Faria, UNIMONTES, 2013.
    Abstract Entender a força relativa dos fatores e interações que determinam as mudanças na estrutura das populações e comunidades é uma questão central na ecologia. Grande parte do recrutamento potencial de uma população vegetal é perdida pela predação de sementes, sendo esta uma das principais forças ecológicas e evolutivas que afetam os indivíduos, populações e comunidades de plantas. As plantas podem responder aos herbívoros, desenvolvendo estratégias de defesa baseadas em compostos químicos, de barreiras mecânicas ou de associações biológicas, para escapar ou diminuir os efeitos da predação (Weis & Berenbaum 1989). Além disso, devido à predação de sementes atuar diretamente sobre o fitness das plantas, espera-se que a seleção natural promova estratégias que visem minimizar o impacto da predação, garantindo maior sucesso aos genótipos mais resistentes (Louda 1982; Hulme & Hunt 1999). A predação de sementes por coleópteros em espécies vegetais tropicais é um fenômeno comum, ocorrendo principalmente em frutos maduros (Lisboa 1975). Dentre os principais predadores de sementes florestais se encontram algumas espécies coleópteros pertencentes às famílias Chrysomelidae, Curculionidae, Anthribidae e Cerambycidae (Janzen 1980). Neste contexto, a subfamília Bruchinae, recebe maior destaque dentro de Chrysomelidae por seus representantes serem bastante restritivos quanto à sua dieta alimentar (Bondar 1936), podendo ocorrer especificidade nos níveis de gênero ou família (Johnson 1981; Johnson & Romero 2004; Christianini 2006). Do ponto de vista econômico, estes são os predadores de sementes mais importantes, podendo se desenvolver continuamente nas sementes armazenadas (Lima 1955). Os coleópteros da subfamília Bruchinae são amplamente conhecidos por sua estreita relação com o hospedeiro, sendo todos predadores de sementes (Rámirez & Travesset 2010;12 Delobel et al 1995). Dentro de Bruchinae, membros da Tribo Pachymerini se alimentam exclusivamente de sementes de palmeiras (Johnson et al 1995; Delobel et al 1995). Há vários registros da predação de frutos de palmeiras por invertebrados (Steffler et al 2008; Silva et al 2007; Alves-Costa 2004; Donatti 2004; Scariot 1998), sendo que esta família (Arecaceae) figura entre aquelas com maiores ocorrências de predação por besouros Bruchinae (Johnson et al, 1995; Scariot, 1998). A palmeira Acrocomia aculeata (Jacq.)Lood. ex Mart. (Arecaceae) é uma espécie frutífera, nativa de florestas tropicais, tipicamente brasileira e com ampla distribuição geográfica. Esta espécie apresenta grande utilidade (Lorenzi 2006) e mais recentemente seu fruto tem despertado grande interesse sócio-econômico por sua capacidade de produção de óleo vegetal, sendo citada como umas das principais fontes deste óleo no Brasil. Entretanto, o estabelecimento e a manutenção das populações A. aculeata ficam limitadas pela forte predação exercida por besouros Bruchinae, que podem destruir mais de 70% dos propágulos produzidos (Scariot 1998). Neste contexto, este trabalho visou entender os fatores que determinam a predação por besouros Bruchinae em frutos de A. aculeata. Para tanto, foram propostas duas abordagens de investigação que compuseram os dois capítulos desta dissertação. No primeiro capítulo, testamos a hipótese da diversidade genética, que prediz que o fitness aumenta com a diversidade genética (Karlin & Lieberman 1979a, 1979b; Ginzburg 1979). Assim, populações de A. aculeata geneticamente mais diversas sofreriam menor ataque por Bruchinae por apresentarem um arsenal de características que podem conferir defesa à predação. No segundo capítulo, exploramos o papel das interações indiretas envolvidas no sistema predador-presa, predizendo que fungos decompositores são mediadores de uma interação indireta entre herbívoros e predadores, e que tem forte influência sobre o comportamento de oviposição de Bruchinae. Nesse sentido foram realizados experimentos a13 fim de testar, primeiramente, se injúrias no epicarpo provocadas por herbívoros em pré- dispersão favorecem a colonização por fungos decompositores em frutos após a dispersão. E ainda, se frutos colonizados por fungos decompositores influenciam a seleção do sítio de oviposição pelo predador. Com isso, as taxas de predação por Bruchinae em A. aculeata seriam determinadas por um complexo de interações ecológicas envolvendo planta-herbívoro- decompositor-predador de sementes.

  66. Paulo Henrique Gonçalves Ferreira. Predação e germinação de sementes de babaçu (Attalea vitrivir Zona, Arecaceae). Marcio Antonio Silva Pimenta, UNIMONTES, Maio 2012.
    Abstract Seed predation is a natural phenomenon can occur pre-or post-dispersal, both representing a significant reduction in reproductive potential of the host plant, could eliminate most of the seeds, which compromises the reproduction of the specie. For a better understanding of plants reproduction, information on the germination of seeds are important for contributing to the understanding of the successful establishment of species in the field. As there is little knowledge about predation and germination of Attalea vitrivir Zona, this study aimed to evaluate the predation and germination of this species in the Area de Proteção Ambiental do Rio Pandeiros (APA-Pandeiros) in northern Minas Gerais. It was observed, monthly fruit production in 60 plants in the period June 2009 to September 2010 and were conducted two parallel experiments. The first in the specie’s natural environment and the second under artificial conditions in a greenhouse. The experiment in the natural environment consisted of 800 fruits, 400 scarified and 400 intact (control), left on the field for eight months for assessment of predation and germination. In the greenhouse, was used 360 fruits, 180 scarified and 180 intact, which were planted individually in black bags of seedlings. The results showed that the fructification of A. vitrivir is continuous occurring during the observation period. The morphology of the fruit was not associated with the germination and predation rate. Scarification of the fruits had no effect on germination, but there was preference for oviposition in scarified fruits by Pachymerus cardo. Seed predation by this insect occurred only post dispersal. In natural environment, the predation rate was relatively low, reaching 14.60%, with no differences in time. The occurrence of severals developmental stages of P. cardo during the 8 months of exposure of the fruits in the natural environment suggests possible diapause of this insect. None of the fruit in natural environment germinated during the 8 months of exposure. In the greenhouse, the germination reached 33.05% after five months. Lattes PDF BibTeX

The results showed that the fructification of A. vitrivir is continuous occurring during the observation period. The morphology of the fruit was not associated with the germination and predation rate. Scarification of the fruits had no effect on germination, but there was preference for oviposition in scarified fruits by Pachymerus cardo. Seed predation by this insect occurred only post dispersal. In natural environment, the predation rate was relatively low, reaching 14.60%, with no differences in time. The occurrence of severals developmental stages of P. cardo during the 8 months of exposure of the fruits in the natural environment suggests possible diapause of this insect. None of the fruit in natural environment germinated during the 8 months of exposure. In the greenhouse, the germination reached 33.05% after five months.",

    Abstract Palmeiras do complexo babaçu (Attalea sp.) proporcionam grande variedade de recursos extrativistas não madeireiros com excepcional potencial de uso agroindustrial. Como existe pouco conhecimento sobre o processo germinativo no grupo, este trabalho objetivou avaliar aspectos estruturais do diásporo e fisiológicos do processo germinativo em Attalea vitrivir, espécie adaptada ao clima sazonal do bioma Cerrado. Avaliou-se a morfologia dos frutos e plântulas, o efeito do armazenamento dos diásporos sobre a germinação e o efeito do pericarpo na absorção de água pelas sementes. Caracterizou-se a embebição, determinou-se o efeito da temperatura, da retirada do opérculo e do ácido giberélico (GA3) sobre a germinação e avaliou-se a biometria, anatomia e histoquímica de sementes e plântulas. O controle da germinação ocorre por meio de uma complexa interação entre aspectos estruturais e fisiológicos. O pericarpo protege a semente e causa dormência física que, em interação com o requerimento de temperatura, pode postergar a germinação para períodos chuvosos subsequentes. O padrão de desenvolvimento da plântula favorece seu enterrio e proteção. Parte das sementes apresenta dormência fisiológica não profunda, associada ao opérculo. Não existe dormência morfológica, apesar de o eixo embrionário ser microscópio e o eixo hipocótilo-radícula parcialmente diferenciado. A germinação e o desenvolvimento inicial são proporcionados pelo alongamento das células do cotilédone e pela atividade de dois meristemas distintos na região proximal. A mobilização das reservas embrionárias inicia-se na embebição e é suficiente para sustentar a germinação. O haustório se desenvolve em estrutura especializada e participa ativamente da mobilização das reservas da semente. Lattes PDF BibTeX

    Abstract During ontogenetic development, plant leaves go through changes that affect the interactions with insect herbivores. The main leaf ontogenetic changes involve variations in tissue nutritional quality, variations in timing of leaf expanding/maturation, and indirect defenses. This study aimed to evaluate the effects of leaf ontogeny the anti- herbivores defense strategy in Copaifera langsdorffii and Hymenaea stigonocarpa, testing two hypotheses: (i) leaves that present higher initial growth rates accumulate more tannins and (ii) ants that forage in NEFs of C. langsdorffii and H. stigonocarpa negatively affect the insect herbivores. Twenty-nine C. langsdorffii and Twenty-nine H. stigonocarpa individuals were selected and observed during seven consecutive weeks from November to December 2010. To measure leaf growth the leaf expanding rate was calculated and tannin concentration was compared between both species. An ant exclusion experiment was realized where two branches of each plant were marked and monitored during leaf expansion. The results of this work revealed that leaves of H. stigonocarpa exhibit higher initial growing and higher tannins concentration than leaves of C. langsdorffii. The ants exerted an effective defense against herbivores insects only in C. langsdorffii – branches were ants were excluded exhibit more herbivores than branches where ants were allone. A reduction in ant abundance along the leaf development was observed as well. These results indicate that the direct defenses (temporal escape and tannin production) prevailed in Hymenaea stigonocarpa whereas the indirect defense was more effective in Copaifera langsdorffii.

    Abstract The high degree of endemism and high biodiversity, occupying the higher altitudes of the regions of rocky fields of Serra do Cipó have been explained by a mosaic of vegetation types, terrain, microclimate variation and the properties of various soil types. On the other hand, such diversity and endemism may have been influenced by the diversity of mycorrhizal fungi (AMF). This work aimed to verify the composition of AMF in soils in the complex rock along the elevation gradient in Serra do Cipó. We analyzed the AMF richness, glomerospores density and soil properties through the generalized linear model and regression at 5% significance seven elevations. The relationships between soil properties and species of AMF with the elevations were analyzed by CCA. To verify the species composition of AMF ANOSIM test was used for subsequent application of Cluster Analysis. To assess the efficiency of the sample curve was constructed for each elevation species accumulation. 4Evaluated soils are acid and nutrient-poor and sandy texture. We sampled 58,621 glomerospores and 53 species of AMF. The sandy soil variables, pH, organic matter, base saturation and cation exchange capacity were the ones with the highest correlation with the two ordination axes and influence the separation of elevations and species. There were significant differences in species composition between the elevations (p <0.05). Observed the formation of clustering at two levels of similarity, and the elevations closest were more similar to each other. The accumulation curves species showed the need to collect more portions each elevations since showed no stabilization.

    Abstract Copaifera langsdorffii Desf. (Fabaceae) is a arboreal tropical species with supra- annual fructification and from 10 to 15 m of height, attaining 35 m. The pattern phenologyc and plant’s size are characteristics that can affect the number and the size of the produced seeds, being also in the predation of the same ones. The variation of the number e the size of produced seeds, caused by the pattern phenologic and the plant’s size has direct consequences reproductive success of the species. Therefore, the objective of this work was characterize any aspects of the reductive ecology of C. langsdorffii. The chapter I had like objective to analyze the reproductive strategy of C. langsdorfii between and inside of years of high and short reproductive investment, testing the hypothesis of trade-off size/number of seeds. So, we supposed that: (i) in the year high reproductive investment the plant produce larger number of seed with smaller size when compared with year of short investment; (ii) inside of the same reproductive event there are an inverse relationship between the number and the size of seeds produced of plant and (iii) the size of plant influences the results of trade-off size/number of seeds. Were selected 33 reproductive individuals in 2008 and 30 individuals in 2011 for data collection. The results of this work demonstrate that as larger number of seeds for plants smaller the size of produced seeds. That effect was only visible inside of the same reproductive event. Were observed that the production of seeds varies in function of the reproductive year and the size of plant. In 2008 were xiobserved that as larger the plants, larger the number and the size of produced seeds. In 2011, short plants produced more seeds while bigger individuals produced larger seeds. The capacity of change the reproductive strategy in function of the corporal size can represent a competitive advantage of the specie, promoting its full distribution for different environment. The chapter II were appraised the relationship between the size of seeds, the germination and the performance of the seedlings, testing the follow prediction: (i) larger seeds present greater percent of germination; (ii) smaller seeds present short time of germination; (iii) larger seeds produced seedlings more vigorous. In 2011 were selected 30 individuals of C. langsdorffii in which were random collect 300 fruits in the long of the canopy for determination of the biometry of seeds. The seed were allocated in tray germination using vermiculite like substratum. To characterize the vigour of the seedlings, after the fall on the cotyledons the seedlings were removed of the substratum for the determination of the length and the dry weight of the aerial part and root system. The size of the seeds affected the percent of germination. However the result were different from the expected, why small seeds presented larger percent of germination. The time of germination was different between the classes of size. Shorter seeds presented smaller time of germination has larger seeds, corroborating the prediction (ii). Thereby waited, the results demonstrated that bigger seed produce seedlings with larger initial size. The fact of short seeds presented larger percent of germination and germinate more fast favors the colonization of the transitory habitats, however larger seeds form seedlings more vigorous, benefiting the establishment in stable habitats. The chapter III was tested three hypotheses: (i) hypothesis satiation of predators that predict smaller percent of predation in years of higher production of fruits, (ii) hypothesis of recourse concentration that predict larger attack in stains of more xiiconcentrated resource and (iii) hypothesis of architecture the plant that predict larger attack of herbivores in plants architecturally more complex. In 2008 were selected 35 reproductive individuals, and in 2011 others 30 individuals that input in reproductive state were for data collection. The production of seeds of Copaifera langsdorffii varied between the years of study, being the number of produced seeds approximately 26.44% larger in 2008. The resulted of this study show that a percent of predation of seeds of C. langsdorffii were 98.42% larger in year of shorter production of seeds, sustaining hypothesis satiation of predators. The percent of seeds predated were smaller in the plants that produced larger number of seeds. Therefore ours data weren’t capable to support hypothesis of recourse concentration. The plant size and seed size produced affected positively the percentage of predation, both in the year as high in years of low resource availability. This study highlights two important aspects: first, the irregular supra-annual fructification results in survival of a larger number of seeds; and second, the seed predators should select patches of better quality resources as a way to produce more offspring.

    Abstract Habitat heterogeneity and complexity associated with variations in climatic conditions are important factors determining the species richness and composition of ant communities in different terrestrial ecosystems, but little is known about the underlying mechanisms of these effects, particularly in ecotone areas. The objective of this study was to describe the horizontal and vertical distribution patterns of the ant community associated with different vegetation types in a transition area between the Cerrado and Caatinga biomes at the Pandeiros River Wildlife Refuge in Januária, Minas Gerais, Brazil. We tested the following hypotheses: i) habitats with higher tree species richness and density support higher ant species richness; ii) habitats with lower variation in canopy cover support higher ant species richness and; iii) the composition of ant species changes between different vegetation types and strata. Sampling was conducted in three adjacent vegetation types (cerrado, riparian forest and dry forest) and at different vertical strata (hypogeic, epigeic, arboreal and canopy). A total of 113 ant species belonging to 35 genera and 9 subfamilies was sampled. Ant species richness did not differ among vegetation types, but was significantly different among vertical strata, with a higher species richness of ants feeding in the epigeic stratum. Ant species composition differed among both vegetation types and vertical strata. Tree density and variation in canopy cover negatively affected ant species richness. The occurrence of different species in different vegetation types and at different strata suggests an ecological-evolutionary relationship between ants and their habitats and emphasizes the need to implement local conservation strategies in the ecotones between biomes.

    Abstract O estudo avaliou a estrutura, as formas de vida e a composição floristica da comunidade lenhoso de sete pontos ao longo de um gradiente altitudinal do complexo rupestre da Serra do Cipó, MG, além disso, a influência da variações edáficas sobre a distribuição das espécies foi avaliada. Em cada área, foram distribuídas 13 parcelas de 100 m 2 , totalizando uma amostragem de 0,91 ha, onde foram amostrados todos os indivíduos com diâmetro a altura do solo (DAS) ≥ 1 cm. Foram calculados os parâmetros quantitativos clássicos e os índices de diversidade e equabilidade. Comparou-se a composição florística entre os pontos amostrados e a similaridade foi calculada. Diferenças em relação a diversidade, área basal, riqueza e abundância das espécies, além da frequência e riqueza de formas de vida entre as áreas também foram avaliadas. A relação entre a altitude e riqueza também foi determinada e as relações entre as espécies e as variáveis ambientais. Foram amostrados 9672 indivíduos, distribuídos em 278 espécies, sendo que as fanerófitas foram mais representativas, seguidas de caméfitas, terófitas, hemicriptófitas e geófita. As famílias mais ricas foram Asteraceae, Melastomataceae, Fabaceae, Eriocaulaceae, Velloziaceae, Malpighiaceae, Myrtaceae, Rubiaceae e Vochysiaceae. As espécies com maior densidade foram Actinocephalus polyanthus, Vellozia nivea, Richterago polymorpha, Lychnophora pinaster, Vellozia epedendroides, Vellozia albiflora, Neea theifera, Leiothrix crassifolia, Paepalanthus bromelioides e Byrsonima verbascifolia.

Em cada área, foram distribuídas 13 parcelas de 100 m 2 , totalizando uma amostragem de 0,91 ha, onde foram amostrados todos os indivíduos com diâmetro a altura do solo (DAS) ≥ 1 cm. Foram calculados os parâmetros quantitativos clássicos e os índices de diversidade e equabilidade. Comparou-se a composição florística entre os pontos amostrados e a similaridade foi calculada. Diferenças em relação a diversidade, área basal, riqueza e abundância das espécies, além da frequência e riqueza de formas de vida entre as áreas também foram avaliadas. A relação entre a altitude e riqueza também foi determinada e as relações entre as espécies e as variáveis ambientais. Foram amostrados 9672 indivíduos, distribuídos em 278 espécies, sendo que as fanerófitas foram mais representativas, seguidas de caméfitas, terófitas, hemicriptófitas e geófita. As famílias mais ricas foram Asteraceae, Melastomataceae, Fabaceae, Eriocaulaceae, Velloziaceae, Malpighiaceae, Myrtaceae, Rubiaceae e Vochysiaceae. As espécies com maior densidade foram Actinocephalus polyanthus, Vellozia nivea, Richterago polymorpha, Lychnophora pinaster, Vellozia epedendroides, Vellozia albiflora, Neea theifera, Leiothrix crassifolia, Paepalanthus bromelioides e Byrsonima verbascifolia.

    Abstract Diversos processos que atuam em diferentes escalas espaciais são amplamente conhecidos como determinantes da estrutura de comunidades de formigas. Esses mecanismos variam em importância nos diferentes ecossistemas tropicais. Para a comunidade de formigas associadas ao dossel de Florestas Tropicais Secas, os mecanismos determinantes da estrutura de comunidades são pouco conhecidos. A presente dissertação investiga, em múltiplas escalas espaciais, seis atributos de comunidades de formigas associadas ao dossel de uma Floresta Tropical Seca do norte de Minas Gerais: riqueza, composição, diversidade beta, co- ocorrência, dominância, e atividade de espécies. Foram testadas hipóteses ecológicas em dois capítulos com o objetivo de descrever os padrões e verificar quais são os mecanismos determinantes da estrutura da comunidade de formigas associada ao dossel de uma Floresta Tropical Seca. No primeiro capítulo foi verificado que os parâmetros relativos a disponibilidade de recursos e heterogeneidade estrutural do habitat, e que são importantes no número de espécies de formigas não variam entre estágios sucessionais. Foi verificado também que a estrutura da comunidade de formigas muda com o avanço do processo de sucessão secundária, com a manutenção da riqueza de espécies e modificação da composição do estágio inicial para o tardio. Além disso, foi verificado também que a disponibilidade de recursos e a heterogeneidade e complexidade de habitat influenciam a estrutura das comunidades de formigas dos diferentes estágios sucessionais apenas na maior escala espacial de observação (conjunto de árvores em uma parcela), e que este não determina a distribuição do espaço pelas espécies de formigas. No segundo capítulo, as espécies amostradas foram classificadas em três níveis hierárquicos, baseado no comportamento de dominância de isca da espécie. Além disso, a frequencia desses eventos de dominância de isca foi registrado, com o intuito de analisar se a probabilidade de ocorrer dominância de recursos pela comunidade difere entre estágios de sucessão secundária, estratos verticais e períodos sazonais, bem como a atividade média de formigas analisada. Verificamos que o padrão de distribuição das espécies não varia entre estágios sucessionais e períodos sazonais, mas no dossel esse padrão de co-ocorrência das espécies é segregado independentemente da sazonalidade e estágio sucessional analisados. Foi verificado também que existe uma hierarquia de dominância de espécies, e que a atividade biológica das espécies difere entre estágios sucessionais. Os resultados do presente estudo indicam que a estrutura da comunidade de formigas é influenciada pela sucessão secundária com a manutenção da riqueza e modificação da composição, o que provavelmente se deve a disponibilidade de recursos que se mantém durante o processo de sucessão, e a presença de espécies dominantes no estágio tardio, o qual ainda apresenta maior frequencia de iscas dominadas quando comparada ao estágio inicial. Além disso, a disponibilidade de recursos e a heterogeneidade do hábitat gerada por diversos componentes da estrutura da vegetação, como riqueza de espécies arbóreas, altura e conectividade do dossel não determinam a riqueza de espécies de formigas na escala local. Por outro lado, em escalas maiores de observação espacial a estrutura da comunidade de formigas é influenciada pela disponibilidade de recursos existentes, como a densidade de árvores e a conectividade da vegetação. Além disso, a diversidade ! e " 3 observadas foram maior que o esperado pelo acaso em ambos estágios de sucessão secundária, e as diversidades " 1 e " 2 menores que o esperado pelo acaso, e assim não foram influenciadas pelo estágio de sucessão secundária. Por último, a co-ocorrência não aleatória de espécies de formigas somente emergiu no habitat dossel, e na menor escala espacial analisada, que se apresentou segregada sugerindo que algum mecanismo biológico tal como interações negativas pode determinar a distribuição das espécies nesses habitats.

    Abstract We compared these processes in pasturelands and preserved old-growth forests in the Mata Seca State Park and its surroundings. To describe the seed shadows, 15 isolated individuals of C. arborea were marked in each habitat type and seed density was determined up to a 30 m radius from each parental plant. To compare seed predation and germination between pasture and forests, five seeds were offered at 5, 10 and 15m from another 15 individuals marked at each habitat. Habitat alteration affected seed shadows and the dispersal distance was longer at the open vegetation of pasturelands (11.35 m forest vs. 14.21 m pasture). Seed predation was significantly higher in forests (59.05%) than in pastures (9.52%), but mortality by other factors showed the reversed pattern (22.3% vs, 90.2%). Temporal patterns of seed predation, mortality by other factors and germination also differed between habitats. Seed predation started late in pastures, probably because grass growth with the first rains provides foraging protection for predators from their natural enemies. On the other hand, seed mortality by other factors increased drastically in the same period, making most seeds produced in pastures unavailable for ground predators. As a whole, all seeds offered in pasturelands died after four months of experiment, whereas 16.1% of seeds were saplings in forest at the same date. Given the high rates of deforestation of Brazilian tropical dry forests, the absence of recruitment in pasturelands is a serious threat to the viability of C. arborea populations. Lattes PDF BibTeX

    Abstract The endophytic fungi are microorganisms that settle the inner part of the plant tissues in at least one phase of their development and establish a relationship that apparently is not harmful to the hosts. The interaction with endophytic fungi is present in most of the plant species and has influence in their biological mechanisms as the production of secondary metabolites and the defense against herbivores and pathogens. There are some perspectives that the endophytic fungi can occur widely in rain forests due to the high diversity of plant species and to the several kinds of vegetation present in these places. This paper aimed to evaluate the endophytic fungi diversity associated with Goniorrhachis marginata and Cavanillesia arborea and their abscisic acid production (ABA) throughout the foliage cycle of the two species of trees. The endophytic fungi were isolated from leaves of 10 individuals of both species and grouped into morphospecies. The ABA production by the fungi was detected by liquid chromatography (HPLC). From the leaf material collected from C arborea and G. marginata it was obtained the total of 179 isolated endophytic fungi grouped into 31 morphospecies. The abundance of endophytic fungi isolated was significantly higherin mature leaves over young leaves for both tree species, corroborating with other studies. The fungi community of C.arborea differed from the fungi community isolated from G. marginata. The same was observed in relation to the fungi community isolated from young and mature leaves of the two tree species, demonstrating that there was an influence of temporal variation in these communities. Regarding the ABA production, from the 33 morphospecies characterized in this study, 15 produced this phytohormone. The production of ABA by the endophytic fungi may be related to a colonization strategy used by the analyzed fungi, as it has already been demonstrated in other studies, with the ABA increasing concentrations, the leaves become more susceptible to infection and perennial colonization.

    Abstract Vernonia herbacea is a species that is known to produce fructans and accumulates in the cytosol of cells rhizophores. Changes in the metabolism of fructans suggest its role as osmoregulators and thus would be part of strategies of the plant to tolerate periods of water restriction, common sites of occurrence of this plant. In order to evaluate the influence of seasonal variation in fructan accumulation in plants of V. herbacea in this study were collected monthly, qualitative and quantitative analysis of carbohydrates and serum proline in plants native to an area of rocky field. We also determined the relative water content in the rhizophores, soil moisture content of the study area and climatic data collected in the region. These were obtained from the Meteorological Station of Diamantina to be this season near the study area and have similar altitude and climatic characteristics of the city of Itacambira - the collecting of material. As average monthly temperatures reached values between 19.8 o C in dry and 26.8 ° C in the rainy season. Rainfall ranged from 0 mm in August (dry season) to 299mm in November (rainy season) coinciding with moisture in the soil showed minimum values of 6.2% in the dry season and maximum of 25.6% during the wet season. These data reflect well the seasonal climate characteristic of the savannah regions. The relative water content did not show significant variations throughout the study, whereas the osmotic potential had subtle lowering the dry period, suggesting the presence of mechanisms that maintain tissue hydration of rhizophors. The contents of proline did not suffer great variations do not represent a significant meaning when considering their participation in the process of osmoregulation, suggesting that this may have acted only as a biochemical marker of metabolic changes produced by stress. In addition to glucose, fructose and sucrose, all members of the homologous series of the inulin have been identified in both thin layer chromatography, as the anion exchange chromatography with high resolution. In these analyzes, the fluctuation in the content of fructans with a low degree of polymerization was evident and could be related to observations made in the field of phenology (unpublished data). However, with the exception of September, a period of shooting, in which falls were recorded in the levels of sugars, these results were not confirmed in the quantitative analysis of reducing sugar, fructo-oligosaccharides, fructo-polysaccharides and fructose total showed oscillations considerable content and high during the other months of the study, which indicates that in the case of this study, there was no relationship between fructan accumulation and environmental variations observed in rocky fields.

    Abstract Com o intenso processo de fragmentação no qual o Cerrado se encontra, a variabilidade genética das espécies deste bioma tem se tornado cada vez mais comprometida, podendo ser perdida com o avanço desse processo de degradação. Dentre estas espécies, a Acrocomia acuelata conhecida como macaúba, possui grande importância ecológica e econômica, nos setores alimentícios e na produção de biodiesel. Com o objetivo de caracterizar a diversidade e estrutura genética de populações de A. acuelata, foram coletados 150 indivíduos de cinco localidades no Estado de Minas Gerais. Quatro primers SSR foram utilizados para obter os dados genéticos desta espécie. Os resultados indicaram que as populações estudadas apresentam significativos níveis de diversidade genética (Ĥe = 0,54), apesar do coeficiente de endogamia positivo e significativo para a maioria das populações. A significativa diferenciação entre as populações (θ = 0,32 e RST = 0,28) evidencia a estruturação das populações. Em todas as populações, os genótipos se encontram distribuídos de forma aleatória. A partir do dendrograma, construído pelo método UPGMA, pode-se distinguir dois grupos, grupo I com a população ESP, o grupo II com as populações [(MIR, CLP), (GRM, ITA)]. Essas populações, de modo geral, apresentaram índices de endogamia altos e significativos. Os dados obtidos para A. aculeata mostram que a espécie e os ambientes de sua ocorrência devem ser priorizados em programas de conservação genética. Lattes PDF BibTeX

    Abstract The climatic seasonality is one of the main features of Cerrado and as a consequence, the vegetation of this biome has developed several adaptations. Gomphrena marginata Seub. is a herbaceous of ‘campos rupestres’ that has thick underground structure and occurs in a region marked by climatic seasonality. In this context, this study aims to evaluate the occurrence and the seasonality of accumulation of carbohydrates like fructans in underground organs of G. marginata and their relationship with soil water availability and hydric relations of plants. Sample of G. marginata were collected monthly from August 2010 to July 2011 in the ‘campos rupestres’ of Environmental Preservation Area "Complexo Paisagístico Serra Resplandecente " in the city of Itacambira-Minas Gerais State (16°59'47"S, 43°20 '01"W). To this end, monthly quantitative analysis of the levels of total fructose, fructo-polysaccharides, fructo-oligosaccharides, reducing sugars and free proline were carried out in underground organs of G. marginata. It was made qualitative analysis of carbohydrates by Thin Layer Chromatography (TLC) and High Performance Anion Exchange Chromatography with Pulsed Amperometric Detection (HPAEC/PAD). Regarding the hydric aspects, it was established soil humidity, the relative content of water (TCW) and osmotic potential from underground organs cell sap. In addition, rainfall data (mm), relative humidity (RH) and average air temperature were obtained from the website of the Institute of Agricultural Sciences of UFMG. Data were analyzed using simple correlation (Pearson) and all the environmental parameters of hydric and biochemical relations. It was used the "t" Student test for assessing the significance of the correlations in 5% level of probability. During the rainy season (September 2010 to March 2011) it was observed an increase of reducing sugars content while there was a decrease in the content of fructo-polysaccharides. Such changes were also detected in the analysis by TLC and HPAEC / PAD. From August to December it was observed high amount of free fructose and sucrose indicating the occurrence of depolymerization of the fructo-polysaccharides chain. In field it was observed that the flowering period of this species occurred predominantly from September to November 2010. Probably reserve carbohydrates (fructo-polysaccharides) were depolymerized and translocated to the shoot of the plant which was in intense development. During the dry period it was found correlations between the reducing sugar content, parameters RH and soil humidity. In this period there was an intense accumulation of fructo-polysaccharides. This accumulation can be associated with translocation of photoassimilates to the underground system before leaf senescence and abscission which was observed especially in the months of June and July 2010. The species G. marginata probably has strategies to avoid loss of water as the control of stomatal movement and / or acceleration of leaf senescence and abscission. The proline content showed significant positive correlations with the TCW. However, due to the low concentration observed its performance in the osmoregulation is questionable, although it is not ruled out the possibility of being a flag. It was concluded that the accumulation of fructans in the underground organs in G.marginata is seasonal. The depolymerization of fructo-polysaccharides occurs during the rainy season which coincides with the period of plants flowering. On the other hand, during the dry period occurs and accumulation of long- chain fructans. Lattes PDF BibTeX

    Abstract Analysis of the structure and genetic diversity of populations allows the establishment of appropriate management plans for species and allows the appropriate use of natural resources. In addition, evaluate the persistence of species over time and subsidize conservation strategies in situ and ex situ. To obtain useful informations for conservation programs and the use of genetic resources, the technique based on SSR (Simple Sequence Repeats) molecular markers are increasingly used for the analysis of population genetics, because of the highly polymorphic and informative. Thus, we successfully transferred 11 primer pairs for SSR molecular markers, previously developed for Anacardium occidentale L. for Anacardium humile St. Hilaire, a species chosen in this study due to its biological importance, medical and socio-economic in Cerrado. All markers had a high information content, demonstrating robustness to genetic analysis of populations. So, six microsatellite loci were used to evaluate the genetic structure of Anacardium humile populations, distributed geographically in the north of Minas Gerais State. For the genetic analysis 242 individuals from eight populations were sampled and genotyped. The results showed high genetic diversity in the populations studied (Ĥe=0.710), despite the significant coefficients of inbreeding ( = 0.142, p < 0.001). Genetic differentiation among populations was significant (p < 0.0018). This differentiation may be due to the clusters of related individuals within populations, in which, in general, levels of inbreeding were high. The endogamy probably contributed to the development of genetic structure in the populations evaluated. The non-random distribution of genotypes in most populations has been attributed to the form and life habits of the species, which influences the foraging behavior of pollinators and seed dispersers. The results reveal the need to implement conservation genetics programs to maintain this species. The existence of high genetic diversity in populations of A. humile exhibits their potential for conservation. To develop strategies for ex situ and in situ conservation it is essential to maintain greater genetic diversity. In addition, the effects of Cerrado degradation and the extrativist exploitation may be better evaluated in other generations, since according to the results, these effects tend to cause loss of genetic diversity in the species.

    Abstract The deciduous forest (FED) is a type of vegetation that loses more than 50% of their leaves during the dry season and hosts a rich diversity of organisms. However, little is known about the fauna of dung beetles and the factors that determine their distribution in FEDs. Thus, this study aimed to describe the distribution patterns of community escarabeíneos (Coleoptera: Scarabaeinae) in fragments of deciduous forests and its relation to the habitat in six neighboring regions of Brazil. For this, we tested the following hypotheses: i. The species composition is determined by escarabeíneos- evolutionary historical events, thus areas of Brazilian FEDs have a similar composition of species of escarabeíneos ii. The species composition is determined by escarabeíneos recent ecological processes, thus areas of Brazilian FEDs have a composition more similar to the neighboring fragments. Six fragments of FEDs and their neighboring habitats were sampled at the following locations: Parque Estadual da Mata Seca, PEMS, Manga (MG); Fazenda Independência, Itambé (BA); Fazenda Sabonete, Posse (GO) Parque Estadual do Turvo, Derrubadas (RS); Fazenda Tamanduá, Santa Terezinha (PB) and Curripira das Araras, Barra dos Bugres (MT). Dung beetles were sampled with pitfall traps installed in the ground and baited with human feces. A total of 8,555 individuals in 93 species of escarabeíneos (FEDs in 83 and 64 in neighboring habitats) were sampled, the species sampled, 58% were shared between the Feds and their habitats neighbors. Among the areas studied we found the highest species richness in the state of Goiás (35 species) and richness in the lower Rio Grande do Sul (15 species). We observed changes in richness and abundance of dung beetles when comparing the different states of fragments sampled and the FEDs with its neighboring habitats (p <0.05). According to the analysis of composition, the fragments of FEDs do not have a similar fauna, or have species composition distinct. They also have a distinctive fauna 10habitats of their respective neighbors. We can conclude that community structure of escarabeíneos can be determined by both environmental factors and recent historical factors and by depending on the spatial scale worked. With this, we highlight the importance of conservation of the fragments of FEDs and adjacent vegetation, and increase knowledge about the distribution of the subfamily Scarabaeinae FEDS in Brazil.

    Abstract The deciduous forests, the so-called tropical dry forest formations are characterized by different levels of shedding during the dry season, with more than 50% of subjects without foliage in the unfavorable period. The endemic flora is beginning to show local extinctions in the country. Thus, this study aimed to evaluate the genetic diversity of Enterolobium contortisiliquum by ISSR molecular markers, populations within the protected area of Lapa Grande State Park and outside the protected area. Total DNA was extracted from leaf tissue of adults and progeny. We calculated the percentage of polymorphic loci (P), expected heterozygosity (He), the Shannon index (I) and estimated allelic flow (Nm). The genetic identity and genetic distance were also calculated. A hierarchical analysis of molecular variance (AMOVA) was used to examine the genetic structure within each population and between populations. A total of 313 individuals were evaluated Enterelobium contortisiliquum, being of the population LAP 162 (148 adults and 14 progeny) and the ELP 151 (144 adults and 7 progeny). Five primers were selected to present bands of good intensity. The primers used generated 49 loci with 25 polymorphic. The analysis of molecular variance indicated that a greater percentage of genetic variation occurred within populations and not between them. The data show that adults and progenies of ELP are genetically more distant. The progenies of the two areas are the individuals who share the greatest genetic similarity. Lattes PDF BibTeX

    Abstract This work aimed to evaluate the survival and growth of samplings of indigenous species and the performance of natural restoration in a riparian forest degraded by cattle pastures in plots of 1 ha, including open areas (AA), fenced areas (C) and dunged areas (E), including even models with direct sowing (S) and the sampling planting in spaces of 2 or 4 m (T2 and T4) and with the presence and absence of direct sowing (T2S and T4S). The samplings growth and survival were monitored in the planted plots, and for all models plots to register the natural regeneration were allocated, during 12 months. The greater growth (in height and diameter) of samplings was associated to the plots (T4 and T4S) located in soil that showed greater amounts of phosphorus, greater proportion of clay and minor proportion of sand. The survival of sampling was high in all models, however was greater in the T2S (78,49%) model. The initial height of the samplings influenced their survival, once that samplings with greater initial height had less mortality rates. Were registered 145 species, being 106 herbaceous, and 39 shrub and tree species in the plots of natural restoration. In light of the preliminary results, it can not be concluded which is the best restoration model at the moment, but it can be concluded that the soil has an impact on the samplings growth, and the treatments that had been done in the area and the initial height of sampling can determine its survival. Besides, as it was observed, despite the changes that the pasture caused on the area, it is in a natural restoration process. Lattes PDF BibTeX

  84. Thaise Oliveira Bahia. Variação estrutural e florística da comunidade arbórea em veredas sob efeito de impacto ambiental na APA do rio Pandeiros, MG.. Yule Roberta Ferreira Nunes, UNIMONTES, Julho 2011.
    Abstract The objective of this study was to characterize the flora and plant community structure of six veredas (palm swamps) at different stages of conservation through floristic and phytosociological description and comparison of the structure, composition, richness and abundance. In each area 100 plots of 100 m 2 were distributed, totaling 6 ha sampling, where we sampled all individuals above the 3 cm in diameter at breast height (DBH, 1.30 m above the ground). The classic quantitative parameters were calculated and the diversity and evenness index, and floristic similarity by cluster analysis. Variations of richness and abundance (GLM) and the structural characteristics of basal area and size distribution were compared among the selected areas. It was determined the relationship between vegetation and environment (CCA) and the preferences of species for specific habitats (ISA). It was found 7965 individuals in 53 families, 102 genera and 165 species identified and three unidentified. The richest families were Fabaceae, Melastomataceae, Myrtaceae and Lauraceae. The 10 most abundant species were Tapirira guianensis, Xylopia emarginata, Zygia latifolia, Cecropia pachystachya, Byrsonima pachyphylla, Myrsine umbellata, Calophyllum brasiliense, Calyptranthes widgreniana, Miconia sp. and Tapirira obtusa. The diversity and evenness indices were 3.573 and 0.698, respectively, for the total sample. There was great phytosociological and structural composition variation. The sites have suffered different levels of degradation and therefore the richness and abundance differed among areas, as well the values of total basal area, height, and diversity varied. These differences show that most disrupted veredas present reduced structural parameters compared to those preserved. The data revealed the formation of three groups: preserved areas, those with intermediate level of disturbance and more disrupted ones. There was also a separation of species. The highest proportion of shade-tolerant and light-demanding species was found in less disturbed areas. Thus anthropic disturbances have caused changes in the natural composition, with loss of species and biomass reduction. It is demonstrated in this study that environmental impacts have affected the structure of the tree community decreasing the richness, abundance and diversity in the veredas with higher rates of degradation.

In each area 100 plots of 100 m 2 were distributed, totaling 6 ha sampling, where we sampled all individuals above the 3 cm in diameter at breast height (DBH, 1.30 m above the ground). The classic quantitative parameters were calculated and the diversity and evenness index, and floristic similarity by cluster analysis. Variations of richness and abundance (GLM) and the structural characteristics of basal area and size distribution were compared among the selected areas. It was determined the relationship between vegetation and environment (CCA) and the preferences of species for specific habitats (ISA). It was found 7965 individuals in 53 families, 102 genera and 165 species identified and three unidentified. The richest families were Fabaceae, Melastomataceae, Myrtaceae and Lauraceae. The 10 most abundant species were Tapirira guianensis, Xylopia emarginata, Zygia latifolia, Cecropia pachystachya, Byrsonima pachyphylla, Myrsine umbellata, Calophyllum brasiliense, Calyptranthes widgreniana, Miconia sp. and Tapirira obtusa. The diversity and evenness indices were 3.573 and 0.698, respectively, for the total sample. There was great phytosociological and structural composition variation. The sites have suffered different levels of degradation and therefore the richness and abundance differed among areas, as well the values of total basal area, height, and diversity varied. These differences show that most disrupted veredas present reduced structural parameters compared to those preserved. The data revealed the formation of three groups: preserved areas, those with intermediate level of disturbance and more disrupted ones. There was also a separation of species. The highest proportion of shade-tolerant and light-demanding species was found in less disturbed areas. Thus anthropic disturbances have caused changes in the natural composition, with loss of species and biomass reduction. It is demonstrated in this study that environmental impacts have affected the structure of the tree community decreasing the richness, abundance and diversity in the veredas with higher rates of degradation.",

    Abstract The veredas are a Cerrado phytophysiognomie , dominated by palm tree Mauritia flexuosa L.f. – Buriti specie, considered the key resource for many animals, that use it as shelter and food source, and also by the man, who uses its leaves and fruits as raw material and food. Although they occur in environments protected by environmental legislation (Permanent Protection Area - PPA), the anthropic actions on veredas have affected the populations of palm tree, by reducing the individuals, caused by deforestation, silting and drainage of veredas. This study aimed to evaluate the vegetative and reproductive phenology and morphometric variation of fruits and seeds of M. flexuosa from six veredas at different stages Environmental Protection Area of Pandeiros River (north of Minas Gerais). To phenology, 120 individuals distributed in the study areas were monitored monthly for a period of one year, where we observed the vegetative (bud, green leaf and senescent leaf) and reproductive phenophases (spadix, inflorescence, flower and fruits).The data were correlated with the climatic variables of temperature and rainfall, by Spearman correlation. For biometric analysis, a total of 1800 fruits and seeds were sampled, measured in length, width and thickness and weight. To detect differences in morphometric measurements of fruits and seeds in the areas of collection the analysis of variance was done. At the end of the phenological assessment, we found differences among the veredas studied, they allowed grouping. For areas that have suffered minor impacts we observed more intensive fruit production. In addition, there was a negative correlation of green leaves production with the temperature in preserved areas and positive correlations with vegetative phenophases with temperature and rainfall in areas with higher anthropic interventions. We also observed changes in morphometric measures between study areas, where 87.5% of the highest averages. Thus, the phenological pattern and morphometric measurements of the seeds of M. flexuosa seem to be related to the conservation of the vereda, which implies the need for management programs that indeed promote the conservation of these areas.

    Abstract The identification of functional groups of plants existing over the succession from quantitative or qualitative leaf traits is essential to understand the process of natural regeneration in Tropical Dry Forests (TDFs). The study was conducted at Parque Estadual Mata Seca, in Manga-MG, in forest fragments in three successional stages: initial, intermediate and late. At each stage, three plots were marked in which the five most representative tree species were selected. In these species, the following leaf traits were evaluated during the rainy season of 2009-2010: leaf blade morphology, specific leaf area, polyphenol content, chlorophyll a, b and total content and leaf life span. The production of leaves occurred at the beginning of the rainy season (November) and leaf fall began soon after the leaves were produced, continuing until the dry season (June). Of the individuals sampled, 20% showed leaf regrowth after rain. Unlike literature, there was no statistical difference between leaf dynamics of three successional stages. Most phenological similarity among species of late stage is due to the process of environmental filtering. Similar traits of leaf blade between species were related to the predominance of the families Fabaceae and Bignoniaceae. The polyphenol content decreased along the successional gradient, suggesting that their levels in TDFs are influenced by solar radiation conditions. High chlorophyll content in early and late species is probably related to greater availability of nutrients in the soil. Groups of species with phylogenetic relatedness were formed, indicating that in addition to the floristic similarity, other factors such as availability of soil nutrients may be influencing plant functional similarity in this TDF. The study also helped fill gaps in knowledge about natural regeneration in tropical areas. Lattes PDF BibTeX

    Abstract Seasonality is very important in the birds ecology, because it culminates in large variations in the availability of flowers, fruits and leaves. This variation in the availability of food resources of an environment constitutes an important ecological factor in the composition and dynamics of bird community. Thus, the aim of this study was to investigate the importance of Riparian Forests of the middle San Francisco River as a refuge for birds of Dry Forest and Cerrado (a Brazilian savanna) during the dry season. Field work was conducted at the APA - Pandeiros River in the northern state of Minas Gerais. In this area, we sampled three different vegetation types: Dry Forest, Riparian Forest and Cerrado, all adjacent. Birds were sampled with mist nets at the three areas, at the beginning and end of the dry and rainy seasons. We captured 373 individuals, belonging to 67 bird species and 26 families. The analysis showed that the highest abundance and diversity of birds were observed in Cerrado areas, which also had different community composition in relation to forested environments. From the four analyzed guilds, the community composition analysis indicated that only insectivores were influenced by the vegetation types, while the other guilds had no influence of the studied variables. Our results highlights that the Riparian Forest is an important refuge for birds of immediate environments, especially the Dry Forest, which its avifauna depends on the Riparian Forest in all seasons. Given the interdependence between the forested environments, we suggest the need to preserve both the fragments of Dry Forest and adjacent Riparian Forest for the effective conservation of several birds found in these environments. Moreover, the conservation of the Cerrado areas still existent in the studied region is indispensable, since its avifauna has a low capacity to use immediate environments. Thus, the results pointed out the need for preservation of the whole mosaic of habitats as an essencial aspect for the maintenance of several bird species found in the region of the APA-Pandeiros River.

    Abstract In the Cerrado, the Bignoniaceae family is widely represented by the genus Tabebuia, Tecoma and Jacaranda. Although the genus Tabebuia, popularly known as Ipê, has wide distribution and high economic value, the most studied species of the genus are those of the Amazon rainforest, yet little research on the genetics of this genus in the Cerrado Seasonal Forests. Tabebuia serratifolia and Tabebuia impetiginosa species are used unsustainably and trade in several areas, as in the pharmaceutical and mainly timber. The fragmentation and habitat destruction have caused the decline of populations and local extinction of them. The spatial genetic structure is directly related to the life history of the plant, and can be affected both by processes of ecological and demographic processes and genetic factors. This work aims to study the spatial genetic structure of two species of Tabebuia, aiming to give support to their conservation and management. State Park Altamiro de Moura Pacheco-PEAMP reminiscent of semideciduous forest, southern Goiás were mapped and sampled 31 individuals of T. impetiginosa and 62 individuals of T. serratifolia. All individuals were genotyped using six microsatellite loci. T. impetiginosa averaged 11.3 alleles per locus ranging from 6 (TAU 21), 16 (TAU 28) alleles. Since T. serratifolia showed an average of 4.3 alleles per locus ranged from 2 (TAU TAU 21 and 31) to 8 alleles (TAU 15). T. impetiginosa showed higher genetic diversity (He = 0, 804) that T. serratifolia (He = 0, 473). The inbreeding coefficient (f) was significant for either species (p > 0.00833) and all loci are in linkage equilibrium (p <0.003333). Both species showed significant spatial autocorrelation (b = -0, 0036, p <0, 001). However, the relationship was significant decreases strongly and only 20 meters for both species. Thus, the spatial genetic structure is significant but weak (Sp = 0.036 and T. impetiginosa 0.032 for T. serratifolia). The genetic neighborhood, estimated by the spatial genetic structure was slightly larger than that for T. serratifolia (Nb = 29.92) T. impetiginosa (Nb = 27.35). Our results show that, despite the species being dispersed by wind, this dispersal is limited to short distances, producing a population increasingly relative. Lattes PDF BibTeX

    Abstract The tree Pequi (Caryocar brasiliense Camb.) is found in almost all of the Brazilian Cerrado, being an important source of income for the local populations. New researches have revealed its pharmacological and nutritional importance, due to its high level of phenolic contents. With the goal of knowledge aggregation, valorization of national biodiversity and identification of the potential of plants with possible antioxidant and photo-protecting action, this work had as its goals to fractionate and evaluate the antioxidant and photo-protecting potential of the hydroethanolic extract of the Pequi fruit peel, and to trace perspectives for the amplification of the exploration of this species. To that effect, there were performed extraction, purifications and quantifications of substances with those properties. Initially, the main antioxidant substance was identified through the use of chromatographic techniques and liquid-liquid separation. Afterwards there were performed trials to evaluate the antioxidant capacity through the reduction of the DPPH radical, the photo-protecting capacity through determination of the solar protection factor and cytotoxic effect in cancer cells culture. According to spectrometry mass analysis, the main substance found on the fraction with better antioxidant activity is Gallic acid, being observed a CE 50 for an antioxidant activity of 2.85 μg/mL. The solar protection factor of the purest fraction obtained from the Pequi fruit peel was 14.43, being the best factor among the tested substances. On the cytotoxicity trial, the cancer cells showed DL 50 of 0.3852 μg/mL in a 24-hour exposure time and 0.2547 μg/mL in 48- hour exposure time. In an estimation of Gallic acid production through the exploration of the Pequi fruit peel in one hectare of native Cerrado, it was calculated to be possible to obtain approximately 1.95 kg of that substance, which would provide, not considering costs, about R$ 1.950,00. Therefore, it was possible to identify the Gallic acid as a substance present on the shell of the Pequi fruit in considerable quantities, and that it possesses antioxidant and photo-protecting properties. So, the potentialities of the Pequi tree are reinforced, especially from the exploration the fruit peel, which is currently considered a residue. It was also shown that other ways of exploration of the native areas of Cerrado have potential for being as lucrative as its exploration for agricultural production. Lattes PDF BibTeX

    Abstract The aim of this study was to observe the emergence of Musca domestica under the effect of three control strategies (biological, cultural and chemical) in poultry laying. The experiments were performed on a poultry facility located in BR 365 - km 14 the municipality of Montes Claros - MG in the period from August to September 2010. The poultry has a total of 20 layer-houses, of which one was selected for the experiments. In these facilities, three blocks were selected for treatments application. We used three 10types of control strategies during the experiments: (i) biological control by Metarhizium anisopliae, (ii) chemical control by insecticide triflumuron, and (iii) cultural control made with lime. Seven types of treatments were applied: 1: Metarhizium anisopliae; 2: triflumuron; 3: Lime, 4: triflumuron + Metarhizium anisopliae; 5: Metarhizium anisopliae + Lime; 6: triflumuron + Lime; 7: control group. Samples were collected weekly and were used emergence traps to collect the flies. In all the control strategies used in the experiment there was a significant decrease in the number of emerged flies (p <0.001) in the cones of manure in the control group. This indicates that all control strategies are effective and can be used to control M.domestica in poultry laying. Lattes PDF BibTeX

The experiments were performed on a poultry facility located in BR 365 - km 14 the municipality of Montes Claros - MG in the period from August to September 2010. The poultry has a total of 20 layer-houses, of which one was selected for the experiments. In these facilities, three blocks were selected for treatments application. We used three 10types of control strategies during the experiments: (i) biological control by Metarhizium anisopliae, (ii) chemical control by insecticide triflumuron, and (iii) cultural control made with lime. Seven types of treatments were applied: 1: Metarhizium anisopliae; 2: triflumuron; 3: Lime, 4: triflumuron + Metarhizium anisopliae; 5: Metarhizium anisopliae + Lime; 6: triflumuron + Lime; 7: control group. Samples were collected weekly and were used emergence traps to collect the flies. In all the control strategies used in the experiment there was a significant decrease in the number of emerged flies (p <0.001) in the cones of manure in the control group. This indicates that all control strategies are effective and can be used to control M.domestica in poultry laying.",

    Abstract The aim of this work was to evaluate the seasonality effects on the Culicidae community of a Seasonal Tropical Dry Forest (STDF). The following hypothesis was tested: there is a change in the composition of the Culicidae community between dry and wet season, with higher values of species richness and abundance during the wet season. This study was carried out in the Parque Estadual da Mata Seca (PEMS), located in the São Francisco river valley, Minas Gerais, Brazil. The PEMS is composed by a primary and secondary forest mosaic and dominated by deciduous trees, which 90- 95% leaf loss during the May-September dry season. Culicidae were sampled during the wet (March 2009 and December 2009) and dry (August 2008 and October 2010) seasons, inside a riparian forest and forest fragments classified as early, intermediate or late successional stages. Sampling was conducted using Shannon traps with aid of manual aspirators in a two hours period, during the dusk. We observed a strong influence of season on the Culicidae abundance and richness, indicating a change in the communities composition. Through an Indicator Species Analysis, seven species were associated to the wet season. Although four species were sampled only in the dry season, no species were considered indicator of this period. This is the first study evaluating the climatic factors influence on the Culicidae fauna in a Brazilian STDF Brazilian. Due to its peculiar dynamics, these forests become interesting for studying these variations. Further long term studies that evaluate the influence of climatic variations in the Culicidae distribution and community composition, and their hosts in areas of deciduous forest are needed .

    Abstract In seasonal environments, such as seasonal deciduous forest, there is a marked variation in the arthropod community between wet and dry seasons. Therefore, insectivorous birds that live in these forests, such as Thamnophilus pelzelni, should exhibit varies in their foraging strategy to ensure that their energy demands are met under different resource availabilities. The objective of this work was to test the hypothesis that the diet and behaviour of T. pelzelni change in response to the abundance of prey in the environment. Collections were made in the Parque Estadual da Mata Seca, na area of Seasonal Deciduous Forest, in february, may and september. For each month of collecting, ten sampling points were marked where arthropods were collected by using pitfall traps, composite interseption traps and through beating. Simultaneous to the arthropod collection, and at the same sampling points, the diet of individual birds was sampled by forced regurgitation. In addition, foraging behaviour in this species was studied through focal observations. The results show that there was no relation between the richness of items ingested by T. pelzelni and the abundance of prey in the environment, while the abundance of prey consumed by this species increased with the reduction of resource abundance. The composition of the diet of T. pelzelni was similar in february and may and only differed in september. In february and may the most abundant prey in the diet of T. pelzelni were Orthoptera, Arthropoda pupa and eggs and Coleoptera, while in september there was a significant increase in the amount of Isoptera and Formicidae consumed. The individuals of T. pelzelni foraged as much in the soil as in the forest understory, capturing prey in the leaf litter, leaves, trunks, branches and in the air during flight. The manoeuvres used by this species to capture prey were classified 9as: picking up, flying, stretching, jumping, and stretching the body with the head facing down. There was a difference in the frequency that different substrates and manoeuvres were used during the collecting months. It was possible to observe, through diet and foraging behaviour, the response of T. pelzelni to the availability of resources in the environment. Lattes PDF BibTeX

    Abstract The Deciduous Seasonal Forests or dry forests are jungle formations that show a high degree of endemism, richness of species and environmental diversity. Currently, only 0.09% of all that dry forest are preserved despite representing 42% of all vegetal formation of the planet. Specifically in Brazil, works aimed at understanding how communities of deciduous seasonal forests are organized over time are scarce. In this paper, the focus is on succession and how this mechanism changes the structure of birds community. However, studies that broach how the succession works on birds community in dry forests are inexistent. Thus, the objectives of this study were to verify if there are some differences in birds community and in feeding guilds during the study period. Our results show that there are temporal variations in birds community as much as in the wealth and in the abundance and species composition. There is an increasing number of species and individuals over time. We found a pattern of growth of these parameters on the 3th year of data collection. A likely explanation for the high diversity in this year is the Intermediate Disturbance Hypothesis (IDH). The increase of wealth and abundance is the result of structurally intermediate habitats and highly heterogeneous. Among the guilds, the largest difference was found for nectarivores and frugivores-insectivores. The availability of resources among the years may be the factor that explains the observed differences as much as in the wealth and in the abundance and composition. Thereby, long-term studies are essential to highlight the factors that affect the structure and dynamics of birds community. Lattes PDF BibTeX

    Abstract The bioenergetic potential of Brazil is represented largely by the alcohol and sugar sector, because the sugar-cane is a source of renewable and abundant energy. Besides the use of the sugar-cane juice for ethanol production and use of bagasse for energy purposes, the polysaccharides (mainly cellulose) can be released by enzymatic hydrolysis to be fermented into ethanol and other products with higher added value. The high cost of cellulolytic enzymes represents the biggest challenge to the viability of the process. Currently, the fungi are the main producers of industrial enzymes lignocellulolytic. The Knowledge of the diversity and potential of the fungi from the environment is still a little explored. Therefore, in this study, filamentous fungi were isolated and selected from sugarcane soil environment of the northern region of Minas Gerais state, with the aim of obtaining strains with potential for production of enzymes lignocellulolytic. The samples were collected from soil and waste of sugar cane in post-drought and post-rains periods. The Samples were collected at pre-selected points strategically for a total of 16 samples. 230 morphotypes were isolated of which 124 identified as cellulolytic, through qualitative tests, and of these 5 also hemicellulolytic and 7 lignolytics. The fungus Trichoderma reesei RUT C-30 ATCC 56765 and Aspergillus awamori B.361 U2/1 were used as reference of producer strains of cellulases and hemicellulases. In relation to the quantitative enzymatic analysis, were tested in submerged fermentation in mechanical shaken flasks and in solid state fermentation in stationary culture flasks, 19 morphotypes cellulolytic. Of these, five morphotypes were identified taxonomically, 2 genus and 3 species, namely: Coriolopsis sp. (Basidiomycete), Aspergillus cf. phoenicis, Penicillium raistrickii; Penicillium angulare and Penicillium variabile. In submerged culture with lactose, the Coriolopsis sp. presented the highest endoglucanase activity (CMCase 7.8946 IU/ mL), and the Penicillium angulare and Penicillium raistrickii, increased activity FPase, 0.7103 and 0.6631 IU/ mL respectively. The Penicillium variabile stood out due to its higher activity -glucosidase 1.3356 IU/ mL, greater than the Aspergillus awamori control in the same cultivation conditions Hemicellulosic activity (xylanase) was better presented by Penicillium raistrickii, 5.2161 IU/ mL. Sugarcane bagasse is presented as a good substrate and inducer in culture submerged for CMCase activity produced by Penicillium angulare and Penicillium raistrickii as well as for all analysed enzymes produced by Coriolopsis sp., compared with cultivation with lactose or wheat bran.

    Abstract Um dos principais objetos de estudos da ecologia são os padrões de diversidade de espécies. Antigamente, filósofos e naturalistas se interessaram pelo estudo da diversidade, devido à natureza intrigante da questão. Atualmente, tal entendimento é favorável ao desenvolvimento de práticas eficazes de conservação da diversidade. O termo diversidade biológica, segundo a Convenção de Diversidade Biológica (CDB) refere-se à variabilidade de organismos vivos de todas as origens, compreendendo, dentre outros, os ecossistemas terrestres, marinhos e outros ecossistemas aquáticos e os complexos ecológicos de que fazem parte; compreendendo ainda a diversidade dentro de espécies, entre espécies e de ecossistemas. No presente estudo, o termo diversidade se refere somente à variedade de espécies. Sendo assim, a diversidade é dividida em três componentes (Whittaker, 1972): diversidade alfa, ou riqueza local; diversidade gama, ou riqueza regional; e diversidade beta, que é a variação na composição local de espécies em uma região. Em ambientes lóticos, existe uma grande diversidade de espécies, sendo que a fauna de macroinvertebrados aquáticos é muito representativa. Dentre esses macroinvertebrados, os insetos aquáticos constituem um dos mais importantes grupos, sendo representada principalmente pelas ordens Ephemeroptera, Plecoptera, Odonata, Coleoptera e Diptera (Merritt & Cummins, 1996). Macroinvertebrados aquáticos são importantes organismos que formam elos nas cadeias tróficas, são alimentos para muitos peixes e são fundamentais na transformação da matéria orgânica e ciclagem de nutrientes (Callisto et al., 2001). Além disso, eles são usados como bioindicadores de qualidade de água em programas de monitoramento ambiental (Rosenberg & Resh, 1993, Wallace et al., 1996). Existem várias teorias que tentam explicar e predizer a diversidade e distribuição de organismos. Como objetivos dessa dissertação, foi testada a influência da conectividade sobre a riqueza local de macroinvertebrados aquáticos, e foi testada a importância da teoria neutra e da teoria do nicho para a diversidade beta de macroinvertebrados aquáticos. A bacia hidrográfica do rio Pandeiros, localizada à esquerda do rio São Francisco, no norte de Minas Gerais, foi utilizada como área de estudo. A área da bacia, de 393.060 ha, faz parte da Área de Proteção Ambiental do Rio Pandeiros (APA-Pandeiros), que apresenta as11 seguintes tipologias florestais: Cerrado, Floresta Estacional Decidual, Veredas, e Pântano. A APA-Pandeiros é a maior unidade de conservação de uso sustentável do estado, onde é compatibilizada a conservação da Natureza com o uso sustentável de parte de seus recursos hídricos (Azevedo et al., 2009). Foi desenvolvido um modelo de simulação de metacomunidades em redes hidrográficas, através do qual a riqueza local de espécies é explicada com base na conectividade dos pontos da rede. O item 3 da dissertação trata da descrição e exploração desse modelo. Muita discussão tem ocorrido entre autores que defendem a teoria do nicho e autores que são favoráveis à teoria neutra. No item 4, a riqueza local de macroinvertebrados aquáticos é explicada considerando as idéias neutras do modelo proposto no item 3.

    Abstract (Tree species phenology of riparian vegetation in a transition Cerrado-Caatinga area). Studies on forest transition are important and required to provide information of adapted species at relatively instable environments. The vegetative and reproductive phenology of tree species in riparian vegetation of the Pandeiros river were studied from August of 2008 to July of 2009, in a transition area between Cerrado and Caatinga biomes, in northern of Minas Gerais, Brazil. 943 individuals, distributed in 50 populations, belonging to 30 species of 17 botanical families were observed. It was also observed the period of phenological phases occurrence: leaf flush, leaf fall, total abscission, flower buds, open flowers, unripe and ripe fruits, and we used the Spearman correlations among these phenological phases and the climatic variables of precipitation, temperature and relative air humidity. Leaf flush was registered mainly in the transition period between dry and wet seasons and leaf fall was more intense during the dry season. Some species showed a decidual behavior, with a total absence of vegetative and reproductive structures mainly, in the transition period of dry and wet season. Flowering was concentrated in this period of transition, while the fruiting was less seasonal, with many species fruiting at the end of wet and dry seasons. The vegetative and reproductive phenological phases correlated with to the temperature. The phenological behavior of the studied species was similar to the phenological patterns of the adjacents riparian vegetation physiognomies of the Pandeiros river. Lattes PDF BibTeX

    Abstract The role of habitat heterogeneity on the diversity of organisms is a key concept in biology, and its importance is evidenced in several studies. However, the knowledge about the effects of insect community assembly on exotic trees remains poor. The colonization of insects on exotic trees may be overlaid by taxonomic similarity with the native flora. This study aimed to investigate the effect of habitat heterogeneity in a small spatial scale at individual level and local scale (>100m). The taxonomic similarity was made, evaluating the pattern at local spatial scale (>100m) and large spatial scale (>10km), on the phytophage insects diversity. We sampled three crops and three adjacent native forests. Heterogeneity was measured using transects in both habitats and the diversity of native myrtaceous was determined by plots on the native forest. The insects were classified into feeding guilds. Furthermore, we examined the historical data about the number of events and insect pests richness into five different regions, this data were related with the native Myrtaceae diversity in reserves of each region. Heterogeneity has a positive effect for chewing insect’s diversity, which showed greater diversity in the reserve areas. Habitat heterogeneity effects are unable to explain the diversity of herbivorous insects on crops. On the other hand, chewing insect’s diversity on crops is lower in places with greater diversity of native Myrtaceae, and no relationship was found for the sap-sucking guild. Furthermore, sap-sucking showed similar composition between native forests and crops, but chewing compositions were different. These results indicate that the effects of heterogeneity are limited by the own effects, and emphasizes the role of genetically related hosts. The same effect was found for the richness of insect pests, where regions with the greatest diversity of native Myrtaceae are less attacked. Overall the taxonomic similarity can shape the assembly of phytophage communities on exotic trees, and heterogeneity is important for the maintenance of local diversity of insects. Lattes PDF BibTeX

    Abstract The aim of this study was to investigate the spatial and temporal variation in abundance, richness, structure and composition of different feeding guilds in a Tropical Dry Forest (TDF) in Northern Minas Gerais, and to determine behavioral changes (foraging time) associated to ecological succession in this area. The study was conducted in 12 areas of four successional stages (pasture, early, intermediate and late stages) in the “Mata Seca” State Park, located in Manga, north of Minas Gerais. The typical vegetation of the Park is tropical dry forest dominated by trees that lose 90-95% of their leaves during the dry season (May to October). Bats were captured from eight samples conducted along two years, using 10 mist nets 12 x 2.5 m per night, totaling 96 sampling nights. A total of 542 individuals from five families and 25 species were captured, and the most abundant were Artibeus planirostris (131 individuals), Desmodus rotundus (113) and Carollia perspicillata (89), corresponding approximately 60% of all individuals. Bat abundance was higher, though not significantly different, in the late (n = 230) than in other successional stages. The absence of statistical significance was probably due to the high capture variation within areas of the same successional stage, thus increasing the data variability, besides the relative proximity between sampling sites. Only the proportion of nectarivores differed between stages, with a higher number of captures in the intermediate stage. Bat abundance was significantly lower in dry than wet seasons, but no difference was observed for species richness. Between guilds, only the omnivores and nectarivores varied significantly along the study period. Regarding the timing of bat activity, there was a trend for higher activity in the first hour of sampling, except for hematophagous bats, which showed the opposite behavior. Overall, this was observed for all successional stages, but some deviations can be observed mainly for frugivorous bats. Our results showed that although the loss of late forests will result in loss of diversity, areas in secondary stages of succession are important habitat for bats in TDFs. Due to the lack of studies and the high rate of deforestation observed in TDFs, more studies are needed to known determine general patterns of bat response to degradation in these areas, as well as their effects on conservation measures.

  100. Karla Nunes Oliveira. Ontogenetic and temporal variation in herbivory and defence of Handroanthus spongiosus (Bignoniaceae) in a Tropical Dry Forest.. Mário Marcos do Espírito-Santo, UNIMONTES, Março 2010.
    Abstract This study assessed the diversity of free-feeding herbivore insects (sap-sucking and leaf-chewing), leaf herbivory rate, leaf toughness and content of total phenolics along the rainy season in two ontogenetic stages (young and reproductive) of Handroanthus spongiosus (Bignoniaceae) in a tropical dry forest. Sampling was conducted in December, February and April (beginning, middle and end of the rainy season, respectively). Twenty marked individuals of H. spongiosus were sampled per ontogenetic stage in each period. Herbivore diversity did not differ between ontogenetic stages, but higher folivory rates, higher concentration of phenolic compounds, and lower leaf toughness were observed for young individuals. The highest herbivore abundance was found in December, but the higher folivory increment was observed at the end of the rainy season, despite the fact that leaf toughness and total phenolic content increased in the same period. No significant relationship between folivory with total phenolics and leaf toughness was observed. Ontogenetic successional patterns of plant defense and herbivory seem to be relatively well-established. However, the primary role of phenolics as defensive compounds must be revisited, at least for seasonally dry tropical forests (STDFs). Finally, although the temporal variation in the diversity of herbivore insects found in this study conform to the predicted for STDFs, herbivory temporal patterns seem controlled by complex factors and influenced by climatic conditions and insect identity.

    Abstract Plants have limited resources to invest in reproduction, growth and defense against herbivores. Trade-offs in resource allocation produce changes in plant traits that may affect the higher trophic levels. The aim of this study was to characterize inter-annual variations in resource allocation to reproduction, growth, defense, and their effects on herbivory attack in host plant Copaifera langsdorffii. Thus, 35 trees were monitored during two studied years to assess differential investment in reproduction, vegetative growth, tannins concentration, plant resistance and insect herbivores attack between years of different reproductive effort. The studied population showed high inter-annual variation in fruiting. The reproductive strategy observed in C. langsdorffii did not affect the total vegetative biomass. However, all other evaluated traits (number of branch, growth, leaf biomass and shoot biomass) changed between reproductive and non reproductive years. These results demonstrate the importance of evaluating different attributes of plant development to characterize variations in vegetative investment. In addition, trade-off between reproduction and growth affected tannins production and insect herbivores associated with C. langsdorffii. Plant resistance and galls attack were positively influenced by tannins and leaf biomass. Moreover, the leaf biomass positively affected galls survivorship and negatively leaf herbivory. Therefore, C. langsdorffii has a pattern of masting fruiting with effects on plant growth and herbivore attack. Understanding this important component of animal-plant interaction is essential to elucidate co-evolutionary life histories and the role of herbivory in supra-annual plant cycles. Lattes PDF BibTeX

    Abstract The study aimed to asses the effect of seed size and scarification treatments in germination and the initial seedlings growth of wood species from riparian vegetation of River Pandeiros (APA-Pandeiros), north of Minas Gerais. We selected four abundant species in the area of study: Annona montana, Astronium fraxinifolium, Curatella Americana and Xylopia aromatica. Biometrics studies, seed germination and initial seedlings growth were performed for each specie. For biometric analysis, seeds were evaluated for length (in longitudinal direction), width (in transverse direction), thickness and weight. The seeds of different sizes were subjected to different scarification treatments: (1) mechanical scarification with sandpaper building n° 80, (2) thermic scarification, with immersion in water at 70° C and (3) control, in wich the seeds were left intact. These seeds were snowed in polyethylene bags and placed under observation in a greenhouse. The experimental design was completely randomizaded with a factorial outline of three (seed sizes) × three (scarification treatments), with 10 repetitions of 10 bags each, totaling 900 seeds per specie. The seedlings were recorded and monitored, with measurements of height, diameter, number of leaves and number of nodes over three months to evaluate the initial seedlings growth of the same. The results generated in the stage of germination indicated significant differences in the seed size only in the for Annona montana. In the initial growth seedlings phase, some assessed measures varied in response to seed size. However, without direct evidence of large seeds in vigour of the species. Moreover, it wasn ́t identified patterned behavior in measures of vigour followed for the four species. Thus, the hypotesis of the work, which predict that, seeds of large size are related (1) higher germination potential, and (2) vigorous seedlings with larger diameter, height, leaf number and number of nodes, weren`t confirmed.

  103. Alessandro Araújo Ferreira Dornelas. Avifauna do Parque Estadual da Mata Seca. Gerardo Arturo Sanchez-Azofeifa, UNIMONTES, Março 2010.
    Abstract This study aimed to characterize the avifauna of the Mata Seca State Park (MSSP), situated in the district of Manga, north of Minas Gerais state, Brazil. The tropical dry forests constitute one of the most threatened ecosystems in Brazil, and little is known about them. In the first chapter, we described the species diversity across the following habitats of the park: dry forests, lakes, riparian forests and abandoned pastures. The species were classified according to their guilds, dependence of forest area, sensibility of the species as ace disturbances anthropic, and conservation status at the global level and at the state of Minas Gerais level. For species sampling, we used the list method of Makinnon and Phillip (1993), with the modifications suggested by Herzog et al. (2003). We registered 202 bird species distributed into 51 families. The most abundant family was the Tyrannidae (15%), followed by Furnariidae (6%) and Picidae (5%). The species as the largest frequency indexes were: Columbina squammata (0,301), Coryphospingus pileatus (0,216), Icterus jamacaii (0,216) e Aratinga cactorum (0,203). The most representative guilds were the insectivores, with 45% of the registrations, followed by the omnivores with 24% and granivores and carnivores, with 9% each. The independent species of forest areas represented most with 41%, the semi-dependent ones represented 37% and the not dependent 22%. As the sensibility of the species in relation to the disturbance antrópica the species with low sensibility represented 62,8%, the with average sensibility represented 33,6% and high 3,4%. Seven species are considered as threatened at some level: two species were classified as IN DANGER inside the state of Minas Gerais and globally as VULNERABLE (Xiphocolaptes falcirostris franciscanus and Penelope jacucaca); the species Mycteria americana is considered as VULNERABLE only for the state of Minas Gerai; four species are classified as ALMOST THREATENED globally, but not threatened in Minas Gerais: Hylopezus ochroleucus, Primolius maracana, Knipolegus franciscanus and Arremon franciscanus. The distribution of the species in each physiognomy showed that the dry-forests possess the greatest richness (128 species), followed by abandoned pastures (117), riparian forests (74) and lakes (31). These results show the importance of the dry forests for the preservation of bird diversity at IVthe MSSP and at the Cerrado and Caatinga biomes, since many recorded species are endemic and extinction-threatened. In the second chapter, we characterized the species richness, abundance and bird community composition across a dry forest successional gradient (early, intermediate and late stages) in the MSSP. Also, we determined how community composition changes between successional stages due to seasonal changes along one year. For this purpose, we used the point-fixed method (Blondel et al. 1970, Bibby et al. 1992), which consists of establishing observation points inside the sampled areas. Points were 200 m distant from each other and all birds inside a 50 m radius from the point were recorded for 10 min. The initial stage showed the highest bird richness (78 species), followed by intermediate (67) and late (65) stages. Community composition in the early stage was also different from advanced stages in both dry and rainy seasons. Intermediate and late stages had a similar bird composition, species richness and abundance at each season. However, bird communities changed significantly between the dry and rainy seasons for all stages. The displacement of some species between stages across seasons is probably determined by differential resource availability. Plant composition and phenology differs between successional stages, especially between the early and the other two advanced stages, changing the spatial availability of flowers, fruits and seeds. Given the importance of the dry forests for the regional bird diversity and their current high level of disturbance, urgent conservation strategies are needed to preserve forest integrity in the north of Minas Gerais.

    	abstract = "This study aimed to characterize the avifauna of the Mata Seca State Park (MSSP), situated in the district of Manga, north of Minas Gerais state, Brazil. The tropical dry forests constitute one of the most threatened ecosystems in Brazil, and little is known about them. In the first chapter, we described the species diversity across the following habitats of the park: dry forests, lakes, riparian forests and abandoned pastures. The species were classified according to their guilds, dependence of forest area, sensibility of the species as ace disturbances anthropic, and conservation status at the global level and at the state of Minas Gerais level. For species sampling, we used the list method of Makinnon and Phillip (1993), with the modifications suggested by Herzog et al. (2003). We registered 202 bird species distributed into 51 families. The most abundant family was the Tyrannidae (15%), followed by Furnariidae (6%) and Picidae (5%). The species as the largest frequency indexes were: Columbina squammata (0,301), Coryphospingus pileatus (0,216), Icterus jamacaii (0,216) e Aratinga cactorum (0,203). The most representative guilds were the insectivores, with 45% of the registrations, followed by the omnivores with 24% and granivores and carnivores, with 9% each. The independent species of forest areas represented most with 41%, the semi-dependent ones represented 37% and the not dependent 22%. As the sensibility of the species in relation to the disturbance antrópica the species with low sensibility represented 62,8%, the with average sensibility represented 33,6% and high 3,4%. Seven species are considered as threatened at some level: two species were classified as IN DANGER inside the state of Minas Gerais and globally as VULNERABLE (Xiphocolaptes falcirostris franciscanus and Penelope jacucaca); the species Mycteria americana is considered as VULNERABLE only for the state of Minas Gerai; four species are classified as ALMOST THREATENED globally, but not threatened in Minas Gerais: Hylopezus ochroleucus, Primolius maracana, Knipolegus franciscanus and Arremon franciscanus. The distribution of the species in each physiognomy showed that the dry-forests possess the greatest richness (128 species), followed by abandoned pastures (117), riparian forests (74) and lakes (31). These results show the importance of the dry forests for the preservation of bird diversity at IVthe MSSP and at the Cerrado and Caatinga biomes, since many recorded species are endemic and extinction-threatened. In the second chapter, we characterized the species richness, abundance and bird community composition across a dry forest successional gradient (early, intermediate and late stages) in the MSSP. Also, we determined how community composition changes between successional stages due to seasonal changes along one year. For this purpose, we used the point-fixed method (Blondel et al. 1970, Bibby et al. 1992), which consists of establishing observation points inside the sampled areas. Points were 200 m distant from each other and all birds inside a 50 m radius from the point were recorded for 10 min. The initial stage showed the highest bird richness (78 species), followed by intermediate (67) and late (65) stages. Community composition in the early stage was also different from advanced stages in both dry and rainy seasons. Intermediate and late stages had a similar bird composition, species richness and abundance at each season. However, bird communities changed significantly between the dry and rainy seasons for all stages. The displacement of some species between stages across seasons is probably determined by differential resource availability. Plant composition and phenology differs between successional stages, especially between the early and the other two advanced stages, changing the spatial availability of flowers, fruits and seeds. Given the importance of the dry forests for the regional bird diversity and their current high level of disturbance, urgent conservation strategies are needed to preserve forest integrity in the north of Minas Gerais.",

    Abstract This study aimed to test two hypothesis 1) Hypothesis of similar composition, which predicts that the composition of the regeneration plant is similar to the composition of tree stratum in the same vegetation type. 2) environmental stress hypothesis, which predicts that vegetation with a lower canopy covery have higher seedling growth, reduced herbivory and increased survival. The floristic composition of the regenerating stratum was described and 45 plots, 15 in cerrado, dry forest and riparian forest in the Area of Environmental Protection Bacia do Rio Pandeiros north of the state of Minas Gerais. Between February (2008) and April (2009) data were collected on height and leaf number of seedlings, herbivory rate and indicated the mortality among a sample and another. We measured the canopy opening in the dry and rainy season through hemispherical photographs. 587 seedlings were monitored. The seedlings richness varied among environments. Growth differed between the months of sampling and was higher in the rainy season. The canopy cover varied between environments and between the months of sampling, reducing in the dry season. The seedling number of leaves differed between months and between environments. The abundance and density of seedlings did not vary between environments, height and seedling growth did not differ between the three environments. There was no relationship between canopy openness and seedling growth. The cerrado had lower canopy cover, seedlings with more leaves, less leaf area and lower mortality. The dry forest showed the lowest seedling richness and greater canopy cover. The riparian forest showed higher seedling mortality and lower mean time to death. The seedling community and the arboreal community varied between environments and each other in the same environment. The first hypothesis was not confirmed, there was a high turnover of species between the two stratum in the study sites, indicating that there may be variation in species composition among the groups. This variation can be affected by local conditions and the degree of human disturbance. The second hypothesis was confirmed, and the environment more subject to environmental stress, with less vegetation cover, had higher seedlings survived, xiiiprobably due to the herbivory. Herbivory was the determining factor in seedlings mortality. The higher seedlings mortality in riparian forest is also linked with greater fragility of this environment. Thus, previous studies of dynamics, structure and succession, should be performed prior to initiating recovery programs. Lattes PDF BibTeX

    Abstract The buriti (Mauritia flexuosa L. f.) is a single-stemed palm tree with wide national distribution, occurring from the sidewalks of the savannah to the estuaries of rivers and flooded areas of the amazon forest. The species contains natural, ecological and socioeconomic importance, besides nutritious and medicinal, being extremely explored by local populations. The knowledge concerning the genetic structure of a population has great application in the conservation and in the management of the biodiversity and it can be obtained with the use of microssatélite molecular markers, which represent powerful tool in the verification of genetic parameters, as genetic diversity, gene flow, genetic drift, among others. This work had as objective the construction of library enriched with microsatellite loci seeking the development and validation of primers for the use in future genetic analyses of the buriti and possible transference of those markers for correlated species. There were developed, from a enriched genome library a total of 160 primers, 30 were tested, of those six were highly polimorphic. Two populations with a medium distance of 40 km between each other, located in APA - Pandeiros, municipal district of Januária, they were evaluated with relationship at the level of existent polimorphism in your individuals. For the study of the genetic diversity there were evaluated 44 adult trees (24 individuals in the population 1 - Vila and 20 individuals in the population 2 - Pindaibal) in the total. These individuals were analyzed using the six polymorphic microssatelite loci, evaluated in polyacrylamide gel and stained with ethidium bromide. The results indicated the emergence of rare alleles in both populations and an average of 11.5 alleles per locus. The values of Ho observed in population 1 had an average of 0.277 and of Ĥe = 0.883, in the population 2, values of Ĥo=0.408 and Ĥe =0.877 were detected. The fixation index were lighter in population 1 (Vila) in relation to population 2. The results found in this study supply important information and will aid in the futures studies of the genetic structure of the buriti, and could be used for the appropriate planning of practices of population sustainable management, especially of those which are explored by the local communities.

  107. Giovana Rodrigues Luz. Germinação de sementes de espécies arbustivo-arbóreas com diferentes mecanismos de dispersão do Parque Estadual da Mata Seca, MG. Yule Roberta Ferreira Nunes, UNIMONTES, Novembro 2009.
    Abstract This study aims to verify whether species with different dispersion strategies are also different in their germinative capacity, in a Deciduous Dry Forests, at the "Parque Estadual da Mata Seca” (PEMS), municipality of Manga, North of Minas Gerais. With this purpose, eight species were compared by their presence or absence of dormancy and five species by the germinative comportment of the seeds after storage for a period of four months. Being so, were selected the following four species with biotic dispersion (zoochorics) Spondias tuberosa, Pereskia bahiensis, Pilosocereus pachycladus and Commiphora leptophleos, and also four species with abiotic dispersion, being two autochorics, Mimosa hostilis and Senna spectabilis, and two anemochorics, Myracrodruon urundeuva and Pseudopiptadenia contorta. The presence of dormancy in the seeds was verified by treatments of chemical scarification (chloride acid), mechanical scarification (sandpaper), and thermic scarification (hot water), while the storage tested was accomplished in the soil of the PEMS and in laboratory (control) during a period of four months. In this last test, at each 30 days, a nylon bag was unearthed, and it's germination was compared with the control, until the completion of 120 days, maximum storage time. The witness seeds of abiotic species, specifically those of anemochoric syndrome highlighted over the others, getting higher percentage and velocity of germination. Also, the species Myracrodruon, Pseudopiptadenia and Pilosocereuss had demonstrated that they don't have dormancy. In the other hand, the autochoric species, Senna and Mimosa, demonstrated dormancy in their seeds, like the most of the studied zoochoric species (Spondias, Commiphora and Pereskia), getting better results with the treatment of mechanical scarification. Between the five species which were evaluated the germination after storage in the soil, just the anemochoric specie (Myracrodruon) showed seeds with short viability. Some species had increases in the percentage of germination over the time, showing that their seeds didn't had fisiological maturity during the collecting period, or had overcame the dormancy during their storage. The species of syndromes autochoric and zoochoric, had a similar germinative comportment, likely due to the presence of dormancy in their seed and to the fact that the dispersion process occurs in the rainy season, they also showed a capacity to compose the soil seeds bank, once they have higher longevity, compared to the anemochoric.

    Abstract The animals need to search for resources and tend to optimize their activities. Insects use ways to reduce the costs of transportation and risk of predation, especially the social insects. The construction of the trails is an example of the benefits of group foraging is greater than the costs, including construction of tunnels. Accordingly, the objective of this study is to test the hypothesis that termites arboreals select resources closer to foraging as a measure to reduce reproductive costs in producing new soldiers and workers. Its implementation, where 40 nests were chosen arboreals located in trees that do not canopy were connected to others. 20 specimens were collected from each nest and up to 5 specimens of each tunnel which were active to a maximum radius of 10 meters, measured with a tape measure is the distance that each tunnel was the nest. Statistical analysis of data was done in software R 2.9.0 , assessing the survival of termite baits within each plot comparing the number of tunnels and the distance tunnels were in the nest. There is greater survival of the termita baits in locations with higher number of tunnels near the nest or at least number of tunnels more distant from the nest. Lattes PDF BibTeX

    Abstract The leaf sclerophylly is characterized by thick and tough leaves due to high concentrations of carbon compounds. The ecological function of this characteristic is still controversial, could be an adaptation to the environmental conditions e/or a strategy to defenses against herbivores. The aim of this study was to verify the effect of the sclerophylly in the attack free-feeding herbivores and galling insects. We sampled three vegetation areas in Refugio da Vida Silvestre na Apa do Rio Pandeiros (Januária/MG): Brazilian savanna Cerrado, riparian forest and seasonally dry forest. All the plants with with circumference at breast height ≥ 15 cm were selected. A common measure of sclerophylly was employed, the specific leaf mass (SLM), obtained through the ratio between leaf dry mass and area. Then, we quantified the leaf area loss by herbivory and were determined the abundance and richness of the gall-forming insects. In the Cerrado was found the higher sclerophylly compared to riparian forest and seasonally dry forest. No statistically significant differences were observed in the gall abundance among habitats. As well as, the sclerophylly did not correlate with the leaf area loss and gall-forming insect diversity. In this way, we study suggest that leaf sclerophylly may be related to plant adaptation in harsh environment and not only mechanical defense against herbivores. Lattes PDF BibTeX

From PSH, three predictions were derived: 1) Plants in xeric habitats are under greater water stress than plants in mesic habitats; 2) Plant water stress have better nutritional quality for herbivores that plants not stressed; 3) The density of eggs and nymphs of G. brimblecombei is greater water stress in plants. Furthermore, it was assessed whether the rates of parasitism of nymphs G. brimblecombei by parasitoids and fungi vary depending on the nutritional quality of individuals of E. camaldulensis. The study was conducted from February to December 2008, in 60 individuals E. camaldulensis (30 in xeric habitat and 30 in mesic habitat) and the statistical analysis conducted in the month of August. This was evaluated the percentage of soil water and water relative content (WRC) to verify the water stress in plants. It was subsequently evaluated the nutritional quality of individuals of E. camaldulensis through measures WRC and chlorophyll content of leaves. The attack of G. brimblecombei was determined considering the average density of eggs and nymphs per cm 2 of leaf. The individuals of E. camaldulensis with lower percentages of water in the soil showed lower WRC. In this system the chlorophyll content of plants was significantly influenced by the WRC of the leaves. The density of eggs and nymphs of G. brimblecombei was higher in individuals with lower WRC and lower chlorophyll content. There was a significant relationship between the average density of eggs and nymphs of G. brimblecombei and all variables related to water stress in plants, as predicted by the PSH. The rate of parasitism of nymphs by P. bliteus and fungi was also higher water stress in plants, indicating a possible dependence on the density of nymphs of G. brimblecombei. The parasitism by fungi was also related with the chlorophyll content. Our results corroborate the PSH, indicating that host xivplant nutritional quality may be the most important regulatory factor in determining herbivore attack the rates and parasitism in this system.

    Abstract The deciduous seasonal forests are poorly studied, yet no standards for their phytosociological structures, recruitment, establishment and dispersal of individuals. For the few studies in these forests do not show the results for the communities considered in areas of major climate change, as the northern state of Minas Gerais. The objective was to find relationships between community structure and rates of germination, germination speed and average time of germination, and test methodologies of experiments that can be important tools for further studies of the structure of deciduous seasonal forests, contributing to the standardization of procedures and comparison of results. This survey was conducted in the municipality of Januária/MG, which were sampled 1.2 hectares of deciduous seasonal forest and recorded 1083 individuals, distributed in 107 species and 80 genera belonging to 35 families. The analysis showed a total basal area of 27.85 m 2 /ha and individuals with height variations between 3.0 and 30.0 m. The most abundant family was the Fabaceae and genera with many species of Machaerium and Tabebuia. The floristic surveys associated with other techniques of analysis, like the tests of germination, may enable a breakthrough in understanding the behavior of ecosystems, helping to understand the adaptive success of species and allowing the understanding of the interactions of plants with microorganisms, with herbivores and other plants. Were selected among the 12 species surveyed, which were divided into two classes based on distinct phytosociological Value of Importance (VI) found in the phytosociological survey, namely: 1st class phytosociological with VI> 30.0 (M. urundeuva, C. Oligandrus, A. fraxinifolium, M. acutifolium, D. bipinnatum and A. colubrina) and 2nd class fitosociológica with VI <30.0 (M. pubescens, A. cearensis, T. aurea, C. americana, C. glabrata and P. Blanchet). These species were collected 1.000 seeds, according to availability at the time of the study. These seeds were tested for germination in complete randomized design with four treatments and five replications, under regulated conditions of 30° C day and 20o C night, with a photoperiod of 12 hours. In general the species in each class did not show similar behavior, which have not occurred for family groups. The species of the family Anacardiaceae (M. urundeuva and A. fraxinifolium) 3showed the largest IVG’s, with peaks of germination in the first three days of the experiment, with positive effect of immersion between treatments. The seeds of A. cearensis and P. Blanchet (Fabaceae) showed positive effect of water on germination original, not affecting the viability of these during the time of the experiment. The species A. colubrina and M. acutifolium (Fabaceae) had a positive effect of water on germination, but showed a decrease of peak germination for treatments of imbibition. In the family Sapindaceae species D. bipinnatum and M. pubescens showed different behavior are not observed the influence of imbibition to the first. The behavior of other species belonging to the families Boraginaceae, Euphorbiaceae Dilleniaceae and proved to be different, with the formation of distinct groups. The T. aurea (Bignoniaceae) showed similar behavior to the species of the family Anacardiaceae. In general, we find two distinct effects of water on the seeds, (i) the initial stimulus to germination and (ii) the decrease in germination with increasing time of imbibition, probably due to the destruction of the seed. The highest rates of germination of the species of the families Fabaceae and Anacardiaceae seem to be influencing the size of populations, but without detriment to other factors that influence the establishment of these. The phytosociological classes do not have a pattern of similarity to justify the structural arrangement of the population for this study. Lattes PDF BibTeX

    Abstract Despite their species richness, importance and although they are protected by law, the riparian vegetation has been gradually destroyed. This study focused in two main objectives: (1) evaluating the floristic composition and structure of natural regeneration of the river Pandeiros, through sampling different sectors of the river, since the spring until the estuary, focusing as the basin as a whole, as the similarity between the different sectors of the river; and (2) studying the possible correlations between the variable of fisionomic structure and the diversity and composition of species from the regenerating shrub/tree community and the environmental variations of one among the sampled points (Balneário), aiming to answer wich environmental factors are preponderant in the spatial distribution of the species in regeneration. For this, had been made, in six sectors of the riparian vegetation of the river Pandeiros, the sampling of the stratum regenerating in 70 plots/ each (5 x 5 m) being comprised individuals between ≥ 1 cm of DSH and < 5 cm of DBH. To determine the influence of environmental characteristics on the floristic and structure of regeneration were gotten some edafics variable, the opening of the canopy and the flooding regime in each plot. Besides the traditional calculations of the phytosociological parameters and grouping analysis to check the similarity betwen the areas, an canonical correspondence analysis it was made to verify the being relations between the environmental variable and the distribution of species in one of the sampled points. In the 420 plots, had been found 232 species shrub/tree, distributed in 152 genera and 57 families. The five families that showed greatest species richness were Fabaceae, with 55 species, Myrtaceae, with 24, Rubiaceae, with 12, Annonaceae with 10 and Anacardiaceae with eight. Were sampled 4374 individual and the more representative species were: Tapirira guianensis, Siparuna guianensis, Blepharocalyx salicifolius, Erythroxylum deciduum and Ladenbergia cujabensis. There were the formation of similarity groups, with Larga and São Domingos areas have been showing bigger similarity, the Agropop and Balneário areas showing little similarity, and Catolé area showed certain similarity with the two cited groups and the Pântano area dissimilar in relationchip the other areas, probably due to ocorrence periodical flooding. Thus, had been a floristic differentiation throughout the river, confirming that near areas are more similar that far areas. Concerning the influence of the environment variable on vegetation of Balneário area, the canonical correspondence analyses showed respectively autovalue of 0,6 and 0,48 for axis 1 and 2. The parcels were divided in three groups, the first group being more influenced by proximity to the calcareous outcrops; the second group by luminosity and flooding regime, and the third by ground fertility (addition of bases). Although there are common species to all groups, many species were exclusive to each group, showing that environmental variable had been influenced the distribution of species. Lattes PDF BibTeX

    Abstract This study aimed to determine the herbivory patterns on the “ipê-amarelo”, Tabebuia ochracea (Cham.) Standl. (Bignoniaceae) in a tropical dry forest in the Parque Estadual da Mata Seca (PEMS), north of Minas Gerais, Brazil. We assessed the diversity of free-feeding herbivore insects (sap-suckers and leaf-chewers), leaf herbivory, leaf nitrogen content, phenolic compounds and spider abundance along the rainy season in three different sucessional stages (early, intermediate and late). The samplings were performed in December, coinciding with the beginning of the rainy season (with fully expanded young leaves), February (middle-aged leaves), and April, in the end of rainy season (old leaves). The samples were performed on 15 trees of T. ochracea per successional stage in each period. Herbivore diversity was higher in the early stage, although higher herbivory rates were found in the intermediate and late stages. This result is probably related to differences in herbivore community composition between habitats and to the better foliage quality in the advanced stages, since the nitrogen content showed positive relation with the enhance in leaf herbivory. The phenolic compounds and the spider abundance did not differ between sucessional stages. The higher herbivore diversity was found in April, due to the increment observed in the early stage. In this stage, the greatest increment in herbivory rates was found from February to April, probably as a consequence of a high incidence of herbivores with tolerance to low nitrogen availability. The intermediate and late stages showed a greater increase in leaf herbivory between December and February, coinciding with the period of higher leaf suitability. As a whole, herbivory and plant quality patterns were similar in the intermediate and late successional stages, and both differed from the early stage. Lattes PDF BibTeX

    Abstract Benthic biotic indices are important tools in assessing the water quality in Biomonitoring Program of river basins. The aim of this study was to evaluate the quality of water in the Biomonitoring Program of the Rio das Velhas basin through the application of benthic biotic index. We evaluated 21 sampling stations (8 in the main river and 13 in the tributaries) in 4 samplings per year from June 2004 to November 2007. For the composition of the index were selected metrics family richness, % Oligochaeta, % Chironomidae + Oligochaeta,% EPT (Ephemeroptera, Plecoptera and Trichoptera),% Gattering-collectors and BMWP - CETEC index were selected. Metrics that were expected to decline in response to the growing impact or disturbance were assigned by score 5 for the values above the quartile of 25%; score 3 for the average between the lowest quartile and 25%; score 1 for the values between the minimum and average value below the quartile of 25%. Bentic metrics that were expected to increase in response to human impacts were assigned by score 5 for the values below the quartile of 75%; score 3 for the average between the maximum and quartile score of 75%; score 1 for the values between the average and maximum value above the quartile of 75%. The metrics aggregation (0-30 points) were divided to establish the criteria for water quality (score of 6-12, poor water quality; 13-18, regular; 19-24, good; 25-30, very good, water of excellent quality). This study also used a Protocol of Rapid Assessment of Ecological Conditions in Watersheds. To establish the criteria for water quality, 9 sites of reference and 4 impaired sites were compared. We performed 317 assessment of water quality, the results showed that 48% were of excellent water quality, 14% good, 19% regular, and 19% poor quality. This methodology will help as a tool in the assessment of water quality in the biomonitoring of watersheds in the short and long term and, furthermore, subsidize with information the implementation of public policy for the management of the Rio das Velhas basin in the Minas Gerais State.

    Abstract Dengue fever is a disease caused by virus infections. Dengue hemorrhagic fever is a more severe form that can be fatal. There is no vaccine against the disease, therefore, the main means of preventing dengue transmission is by stopping its vector. The aim of the present work was to evaluate new devices for entomological control. MosquiTRAP and BG-Sentinel trap were compared to oviposition trap trap and Nasci aspirator. The four sampling methods were simultaneously evaluated throughout 90 blocks of Serrano borough, Belo Horizonte (MG). The four methods were equidistantly set in every block. The three traps were installed in the house areas sheltered from the rain while the aspirator collected mosquitoes from areas surrounding houses and intra house areas. Oviposition trap and MosquiTRAP were checked every week, BG- Sentinel ® was checked during 24 hours every week, and the aspiration 15 minutes per week. Oviposition trap has proven to be the most sensitive method for mosquito detection during all the weeks of evaluation. The higher numbers of adult A. aegypti captured were observed in BG-Sentinel (275 females and 300 males). However, MosquiTRAP has captured a significantly higher number of females when compared to the other methods proving to be more female effective/specific (370) than male (21). Nasci aspirator captured less adults than the traps. Its higher capture percentage was (87%) in house areas. A meaningful correlation was observed between MosquiTRAP and oviposition trap (r=0,55) (p=0,001), suggesting an association between the two methods of capture. Physical factors such as temperature, humidity and rain did not influence the capture of A. aegypti (p>0,05). MosquiTRAP and BG-Sentinel have shown to be effective in capturing A. aegypti and can be used as methods to sample the population of the vector for monitoring and the population of adult mosquitoes in dengue fever control programs.

    Abstract The Intelligent Monitoring of the Dengue (MI-Dengue) is a system that allows to know the infestation of females of the Aedes aegypti in determined local. It is formed by three components: trap for capture of females of A. aegypti (MosquiTRAP), synthetic oviposition attractant (AtrAedes) and softwares for collection and data processing and generation of georrefered maps. This study it had as objective to know the density and distribution of the Aedes aegypti in two quarters (Jardim São Luiz and Major Prates I) of Montes Claros, aiming at to identify a practical form and needs to supply subsidies that one better planning of the actions of control of the illness from the efficient control of the mosquito allows, with consequent aiming and rational use of insecticides. The study the May of 2008 was carried through during January (19 weeks epidemiologists). 30 MosquiTRAP traps had been installed in each quarter, being 1 trap/square. These had been inspected by the health agents. The cases of dengue, the climatic variations and the ambient and socioeconomic characteristics of the studied areas had been evaluated. 865 mosquitoes, being 816 had been captured (94.3%), A. aegypti, 48 (5.5%) Culex sp and only 1 (0.2%) A. albopictus. 709 females (86.9%) and 107 males had been captured (13.1%) of A. aegypti. We do not find significant differences for the number of females between the two quarters (p=0,701). It became related presence and number of females of the mosquito with diverse variable as presence of vegetation, watering holes, lagoons, culverts, breeding containers, strips of land and animal that had not shown to significant relation with the mosquito number and cases of dengue (p> 0, 05). The population density human being presented positive relation with the density of the mosquito, detaching the anthrophofilic character of the same. The rainfall presented significant positive relation with the presence of mosquitoes (p=0,001) and the presence of swimming pools did not demonstrate to be a risk factor (p=0,001; OR=0,197), a time that are dealt duly with chlorine. The presence of garages also showed relation with the transmission risk (p=0,001), probably for containing tires that can become breeding containers of the Aedes. IXThe Average Index of Females of Aedes aegypti (IMFA) significantly disclosed to be a good pointer of the risk of transmission of the associated affection revealing to the cases of dengue in the localities (p=0,005), emphasizing the potential of this pointer as tool of control of dengue for use of the programs of control of this disease.

    Abstract Esta dissertação aborda aspectos relacionados à comunidade de macroinvertebrados bentônicos da bacia hidrográfica do rio Pandeiros. Este documento foi subdividido em Capítulos 1 e 2, Considerações finais, Perspectivas Futuras e Anexos por último. O primeiro capítulo, intitulado “Influência do uso e ocupação do solo da bacia do rio Pandeiros-MG na heterogeneidade espacial de trecho de rio e suas consequências sobre a comunidade de macroinvertebrados bentônicos.”, buscou apresentar os efeitos do uso e ocupação de solo sobre a heterogeneidade espacial (obtidas a partir de métricas abióticas) e as conseqüências da alteração do meio físico sobre a estrutura da comunidade bentônica. Para aferir a heterogeneidade espacial, foram avaliadas métricas como a cobertura da mata ciliar, inclinação da margem, sedimento (matéria orgânica, frações granulométricas), parâmetros físico-químicos da água e o protocolo de avaliação rápida em trecho de rio, e sua importância para a densidade, biomassa e riqueza taxonômica da comunidade de macroinvertebrados bentônicos na bacia hidrográfica do rio Pandeiros-MG. Assim, foi possível construir um texto científico que busca acrescentar informação sobre a influência da estrutura do habitat físico sobre a comunidade bentônica e também uma informação útil para avaliar uma substituição da vegetação nativa na região. Visando a publicação, este manuscrito será submetido a uma revista de impacto internacional. No segundo capítulo que tem por nome “Avaliação ambiental da bacia do rio Pandeiros-MG utilizando macroinvertebrados bentônicos como bioindicadores de qualidade de água” é um trabalho de divulgação. Neste texto foram discutidos os dados gerais sobre a comunidade de macroinvertebrados bentônicos na bacia do rio Pandeiros-MG, através da aplicação de um diagnóstico ambiental por meio do índice BMWP-CETEC e um protocolo de avaliação. Esta informação é importante principalmente para os órgãos gestores, na avaliação dos locais alterados e também na elaboração e execução de estratégias para unidades de conservação. Este capítulo foi submetido para revista Biota - MG, de alcance estadual e encontra-se no prelo para publicação. Lattes PDF BibTeX

    Abstract The Eucalyptus spp. represents the largest planted forests in Brazil and, as with any other monoculture, favors pest proliferation. Currently, these plantations are under the attack of the herbivore Glicaspis brimblecombei Moore (Hemiptera:Psyllidae), also known as the red gum lerp psyllid. This insect usually prefers the species E. tereticornis, E. urophylla, or hybrids with genetic material from E. camaldulensis. This study aimed to determine the attack patterns of G. brimblecombei, evaluating the existence of preference and performance of this herbivore in different habitats. For this purpose, we used two hybrids of eucalyptus and tested the effects of irrigation on psyllid attack, in order to propose biological control strategies. We used 90 seedlings of E. camaldulensis x E. urophylla (Urocam) and 90 seedlings of E. camaldulensis x E. grandis (Urograndis), introduced in centers and borders of three plantations of E. camaldulensis in the Fazenda Extrema, a property of Vallourec Mannesman Florestal (V&M). The seedlings were divided into two treatmens (irrigated and control), and exposed for 45 days (July to September) to the attack of G. brimblecombei. All leaves collected were inspected in the laboratory and all eggs and nymphs of G. brimblecombei in different instars were counted. We did not find significant differences in the densities of eggs and nymphs between leaf surfaces, different clones, and habitats (center x border), but there were significant differences between water treatments. The density of eggs was significantly higher on seedlings treated with water. In this way, further studies are needed to better understand the attack patterns of G. Brimblecombei, which did not show clear preference and performance behavior during the study, except for the effects of water stress. Lattes PDF BibTeX

    Abstract Methanolic extracts from dried and fresh leaves of Psidium guineense, collected in Glaucilandia (MG) city, were submitted to purification by successives extractions with rising polarity solvents: eter oil, dichloromethane, ethylacetate and butanol. The residues from fractions were submitted to antibacterial test against cepas of Staphylococcus aureus ATCC 25923 and Pseudomonas aeruginosa ATCC 27853, by two variants of the agar diffusion method (disc and well). All fractions showed antibacterial activity. According to these results, it was prepared an extract with 70% acetone of dried and fresh leaves of P. guineense, in order to isolate tannins from the plant and evaluate if the content of these compounds in the samples had relation with antibacterial activity observed in the initial test. Thus, the extract was applied to a column of sephadex LH-20 and two methodologies were used for the isolation. The tannins present in the isolated samples were quantified and the samples were submitted to antibacterial test. The samples gotten by two methods of isolation showed a high content of tannins and inhibited the bacterial increasing. The compounds responsible for the antibacterial activity of the samples rich in tannins were extracted with major efficiency from dried leaves and the well variant of the diffusion method was more sensitive to the diffusion from these compounds.

    Abstract An important aspect in development of inactivated vaccines is the adjuvant. The majority of adjuvants that are commonly used is not considered ideal because they induce inappropriate immune response or present side effects. In this work, vaccines against porcine parvovirus have been formulated to assess the adjuvant capacity of vegetal extracts as peanut oil, buriti oil and the extract of green propolis in inducing the immune response in guinea pigs. The experiments were divided in two stages. The vaccine formulated with peanut oil induced higher antibodies titers after 15 days post vaccination (dpv), but not after 60 dpv when compared to the vaccine formulated without adjuvant (control). The extract of green propolis and aluminum hydroxide induced similar antibody titers that were higher than the antibody titers induced by the vaccine without any adjuvant. The buriti oil didn’t show adjuvant activity when it was compared to control vaccine. In the second stage of the work, vaccines were formulated using green propolis, aluminum hydroxide and hydroxide and green propolis association. These formulations and a commercial vaccine have been inoculated in guinea pigs. Similar antibody titers were observed in animals vaccinated with vaccine formulated with aluminum hydroxide and the association of hydroxide and green propolis and with the commercial vaccine. This study has been demonstrated that the extract of green propolis can be used with the aluminum hydroxide as adjuvant of inactivated vaccine against the porcine parvovirus providing a satisfactory immunologic response.

    Abstract Recent projections of climatic change have focused a great deal of scientific and public attention on patterns of carbon cycling as well as its controls, particularly the factors that determine whether an ecosystem is a net source or sink of atmospheric carbon dioxide (CO 2 ). Aquatic ecosystems – atmosphere CO 2 fluxes are mainly determined by balance between CO 2 fixation from primary production and evasion of this gas from respiration, what is named aquatic metabolism. Aquatic systems can show, regarding to atmosphere, a subsaturation and, a net CO 2 sink (autotrophic metabolism) or supersaturation and net CO 2 source (heterotrophic metabolism). The most researches had been shown predominance of heterotrophy in different aquatic systems. Based on CO 2 nictimeral variations, this research provides estimations of different aquatic systems net metabolism in north of Minas Gerais. This research was conducted in four lotic systems and six lentic systems (3 lakes and 3 reservoirs). The systems were, predominantly, autotrophic, what can be related to the lack of organic matter allochthone in the analyses time. Just three systems show heterotrophic biological activity, Lagoa da Prata in the macrophytes banks local, Lagoa dos Patos and Rio Preto, in witch there are continuous organic matter inflow. Therefore, we can conclude that eutrophic systems showed autotrophic metabolism while oligotrophic systems showed heterotrophic activity. The great differences between the systems and their basins, as well as their human use do that the net nictimeral metabolic responses be too divergent. Lattes PDF BibTeX

    Abstract Molecular markers have been each time more used in studies related to the diversity and genetic structure population. These studies are lead with intention to quantify the inside variability and characterizing the genetic structure between populations. The information compiled has been applied to theoretical basis of Conservation Biology, over all in tropical species. For this, the main biological and genetic factors involved to constitution of the genetic diversity and differentiation has been considered. Amongst the diverse factors that happen over population diversity and structure of tropical trees enhance the population size, gene flow, mating system, cerrado selection, forest fragmentation, phenological aspects and pollination and seed dispersal activity. The aim of this work was to add more information about genetic diversity and structure from Caryocar brasiliense trees with different habitat structure. This study was conducted in two localities from northern Minas Gerais State, about 5 km apart one another. The genetic diversity and structure estimates had been gotten from eight microsatellite locos. The results have showed a high level of polymorphism. The fixation index (ƒ) has showed a great genetic similarity for age class and/or areas, which has suggested inexpressive mating values between related individuals. The Θ value has never showed statistical significance, with the F value always higher, which has suggested a low differentiation among C. brasiliense populations. Moreover, a low differentiation among populations has been corroborated to lower R ST values that Θ. It was not observed the occurrence of bottleneck event. However, observed divergence between young pequizeiros into habitats suggests a disruption of the areas, because 12changing of the pollination and seed dispersal behavior and phenological patterns due to habitat structure. Moreover, the relationship estimative (r xy ) between pairs has evidenced higher levels of genetic related closely to young pequizeiros from pasture area. This result has suggested an inbreeding increase of the C. brasiliense populations in disturbed areas although located closely apart. Therefore, the populations of C. brasiliense in spite of show similar genetic content, they should experiment significant increasing in the levels of genetic differentiation along the future generations whether the structure habitats remain like observed.

    Abstract The Tropical Dry Forest comprises vegetal formations that are submitted water scarcity tends and to be dominated by annual species that survive season dry, forming the soil seeds bank. This present work had objective to the respond questions: 1) Does the tree Tropical Dry Forest utilizes the seeds bank as reproductive strategies? 2) Is here fluctuation in the composition of the seeds bank during the seasons of the year? and 3) Does the composition the seeds bank is influenced by environmental factors (abundance and wealth of the wood and scrubland)? Four soil samples was collected from 26 plots 20 m × 20 m (400 m 2 ) each, in two fragments of the Tropical Dry Forest during different seasons of the year. The composition of the seed bank was compared with the above-ground, scrubland, seeds rain and the seasons of the year (February, May, August and November). Were registered 3.667 germinated seedlings with density of 398.9 seeds/m 2 . That was distributed in 53 identified species, 41 genres and 22 families. From 3.667 individuals sampled 1.378 were Euphorbiaceae, 581 Urticaceae and 329 Oxalidaceae. The herbaceous species were the most abundant with 2.771 individuals. The composition of seeds bank had been strongly affected by climatic seasonally, since the abundance of the seeds bank was larger in the dry season and the wealth larger in the wet season. The composition of seeds bank had been influenced by wealth wood and scrubland indicating area better structured has larger seeds bank. This study has been suggested environments factors and the climatic seasonally were important parameters in the composition of this seed bank. Lattes PDF BibTeX

    Abstract Ethanolic and methanolic extracts of 10 plants collected from the Cerrado of the North of State of Minas Gerais (Brazil) were submitted to antibacterial test against the bacteria Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923) e Pseudomonas aeruginosa (ATCC 27853) using the disc diffusion method. The botanical species which presented antibacterial activity, Anacardium humile A. St. Hil, Psidium giuneense SW. and Myracrodruon urundeuva Allemao, had their ethanolic extracts tested in 15 stems of the species Staphylococcus aureus that were obtained from the patients area at the Hospital Universitário Clemente de Faria and from clinical laboratories in Montes Claros and standard stem ATCC 25923. Inhibitory activity was determined and the interaction between the extracts and the main groups of secondary compounds present in these plants was surveyed. Through the study of the antibacterial activity in bacterial stems of Staphylococcus aureus, the extract of Myracrodruon urundeuva Allemao has started its inhibitory action at a 30 mg/mL concentration, while the extracts of Anacardium humile A. St. Hil. and Psidium guineense SW. started their activity at a 60 mg/mL concentration. A synergic interaction between the vegetable extracts was observed when they were combined by pairs at variable percentages. Tannins and flavonoids were detected in the phytochemical analysis of the species; such substances may be responsible for the observed antibacterial action. From these results, other studies should be carried out with the plants Anacardium humile A. St. Hil., Psidium giuneense SW. and Myracrodruon urundeuva Allemao; they have showed a considerable therapeutic potential. Lattes PDF BibTeX

    Abstract The Caryocar brasiliense Camb., family Caryocaraceae, known popularly by pequi, is found in almost all the Brazilian Cerrado, with its main use in cooking and in the agricultural industry for oil extraction and production of liqueurs. New research has revealed its pharmacological and nutritional importance given its high content of antioxidant compounds. In this work, it was aimed to assess the potential of antioxidant extracts made from fruit and leaves of pequi, considering the way of obtaining the antioxidants and active principle responsible for this action. For this, extractions were performed on samples of dried leaves, mesocarp and pulp, using hexane, chloroform, ethyl acetate, ethanol, methanol and distilled water. Fractionation of ethanol extract was carried out using hexane, petroleum ether and chloroform. In each extract were obtained income and was assessed the antioxidant activity. In each fraction were quantified the levels of total phenolic compounds, total flavonoids, tannins and total carotenoids in addition to the antioxidant activity. It was built in HPLC chromatographic profiles of each fraction. As results, the antioxidant activity can be recovered in different solvents used, and better in ethanol, methanol and distilled water. Higher yields are obtained with extracts of ethanol and methanol for sheet and mesocarp and with chloroform and ethyl acetate to the pulp. The ethanol extract showed levels of phenolic compounds, 255.24, 265.48 and 9.01 mg/g, flavonoids, 143.56, 164.23 and 2.23 mg/g, carotenoids, 421.65, 243.38 and 40.72 μ/g, respectively, for fractions of extracts of dried leaf, mesocarp and pulp. Tannins were found in low concentrations in sheet and pulp. There was a direct relationship between levels of flavonoids, carotenoids and antioxidant activity in fractions studied. In conclusion, the antioxidant activity of pequi is better restored in most polar solvents, and indicated the ethanol as a good solvent for extraction. Probably flavonoids and carotenoids are the main substances responsible for the antioxidant activity of pequi. Lattes PDF BibTeX

    Abstract Homegardens are considered important agroforestry systems for household supply around the world, with variable structure and composition. The objectives of this study were: (1) to list plant and fruit-feeding butterfly species in homegardens of two communities located at the surroundings of Parque Estadual da Mata Seca (PEMS), North Minas Gerais, Brazil; (2) to compare fruit-feeding butterfly species richness between homegardens and dry forest patches; (3) to test hypotheses to explain why plant and fruit-feeding butterfly species richness vary between homegardens; and (4) to provide subsidies for elaboration of proposals aiming conservation and sustainable use of natural resources at the buffer zone of PEMS. To explain why butterfly species richness vary between homegardens we tested the influence of plant species richness, homegarden area and distance from the nearest forest patch. To explain why plant species richness vary between homegardens we tested the influence of ecological (homegarden area and distance from the nearest forest patch), historical (homegarden age), cultural and socio-economical factors (mean family degree of instruction, mensal income, number of inhabitants and number of workers). Measurements of area and distance were obtained for 20 homegardens. A floristic inventory was realized to estimate plant species richness. Historical, cultural and socio-economical data were collected by interviews. In order to estimate and compare butterfly species richness between habitats, 20 fruit-feeding butterfly traps were set up in homegardens and 20 traps in the nearest forest patch. We verified higher fruit- feeding butterfly species in dry forest patches when compared to homegardens, emphasizing the hypothesis that butterflies prefer natural rather than human-made environments. We observed positive influence of homegarden area on plant and butterfly species richness. However, fruit- feeding butterfly species richness was not affected by plant species richness and distance from the nearest forest patch. In the other hand, we observed negative relation between plant species richness and distance from the nearest forest patch. Besides, we verified that homegardens established and managed for longer periods of time have higher plant species richness. Despite the positive relation observed between number of inhabitants, number of workers, family median degree of instruction, mensal income and plant species richness, this pattern was not verified when the two studied communities were analyzed separately. Therefore, the influence of cultural and socio-economical variables on plant species richness cultivated in homegardens seems to contribute more to characterize differences between local communities rather than explaining general patterns of biodiversity in homegardens. Finally, we believe that species-area relations observed in homegardens may be promising for utilization of agroforestry systems as models of agroecological production allied to biodiversity conservation outside protected areas.
