1. EVALUATION OF DIVERSITY AND GENETIC STRUCTURE AS STRATEGIES FOR CONSERVATION OF NATURAL POPULATIONS OF Dalbergia nigra (Vell.) Allemão ex Benth.
ABSTRACT: The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR).

2. Plant diversity in hedgerows amidst Atlantic Forest fragments
Hedgerows are linear structures found in agricultural landscapes that may facilitate dispersal of plants and animals and also serve as habitat. The aim of this study was to investigate the relationships among diversity and ecological traits of woody plants, hedgerow characteristics (size, age, and origin), and the structure of the surrounding Atlantic Forest

3. Padrões de distribuição de mamíferos de médio e grande porte em paisagens fragmentadas / Distribuition patterns of medium and large size mammals in fragmented landscapes
Habitat fragmentation is defined as the breaking of a continuous habitat in patches or fragments. This process leads to environmental changes capable of affecting communities in different ways, causing species composition changes. Beta diversity measures can show the variation between the composition of different communities, where two ecological patterns ca

4. Arthropod responses to the experimental isolation of Amazonian forest fragments
Arthropods are the most diverse and abundant group of animals found in tropical lowland forests, and in light of ongoing global change phenomena, it is essential to better understand their responses to anthropogenic disturbances. Here we present a review of arthropod responses to forest deforestation and fragmentation based on studies conducted at the Biolog

5. A rede de marcação e recaptura: o caso de borboletas do gênero heliconius
(A rede de marcação e recaptura: O caso de borboletas do gênero Heliconius). O ritmo atual de destruição dos habitats, especialmente em paisagens tropicais, tem aumentado a necessidade de se ter algum conhecimento sobre fragmentos e distância entre fragmentos como requisito mínimo para a conservação das espécies em remanescentes de florestas. Os es

6. Composition of mixed-species bird flocks in forest fragments of southern Brazil
The present study aimed to evaluate the composition of mixed-species bird flocks in a fragmented landscape of the Atlantic Forest in southern Brazil. We recorded 117 species in 218 mixed-species flocks. The correspondence analysis showed two distinct groups of fragments according to degree of connectivity with other fragments. The percentage of original cove

7. Bird movement patterns in a fragmented landscape and their effects to functional connectivity: an hierarchical approach / Padrões de movimentação de uma espécie de ave em paisagens fragmentadas e seus efeitos para a conectividade funcional: uma abordagem hierárquica
Habitat fragmentation is one of the major human impacts on terrestrial ecosystems. This process highly affects the species movement pattern, implying in considerable alterations on the connectivity between the remaining habitat patches. Consequently, it interferes in the spatial distribution and in the population dynamics of species. In this dissertation, so

8. Conservação de aves de sub-bosque em paisagens fragmentadas: Importância da cobertura e da configuração do hábitat / Influence of habitat amount, fragment size and connectivity in Atlantic Forest bird species conservation
Landscape aspects such as habitat amount, fragment size and connectivity, have been suggested as key features for maintaining species in altered landscapes, and thus are essential to be modeled and comprehended for management and conservation purposes. To test their effects on understory Atlantic forest bird species, we built models with variables representi

9. Dinâmica de uso das terras nos municípios de Bonito, Jardim e Bodoquena (MS) e o estado e conservação dos recursos biológicos do Parque Nacional da Serra da Bodoquena e de sua zona de amortecimento / Spatial and temporal dynamics of land use in Bonito, Jardim and Bodoquena (MS) Municipalities, and the conservation state of the biological resources in the Serra da Bodoquena National Park buffer zone
The research approached the process of use and occupation of lands in the cities of Bonito, Bodoquena and Jardim, situated in the edge east of the National Park of the Serra da Bodoquena (NPSB), southwestern region of Mato Grosso do Sul, Brazil. Moreover, the conservation state was studied, in terms of structure and configuration of the landscape, of the con

10. A ecologia da paisagem e estratégias para ocupação e uso do solo: o entorno da RPPN Santuário do Caraça
The creation of protection areas is an efficient tool for nature preservation, mainly to minimize the impacts deriving of the spalling. This process, understood as the separation of the native nature into smaller and isolated parts, is considered to be one of the most serious enviroment problems of the present time, therefore it provokes the loss of biodiver
