13. Efeitos da fragmentação de habitat sobre a comunidade de pequenos mamíferos de Mata Atlântica no Estado de São Paulo / Effects of habitat fragmentation on community of the Atlantic forest small mammals in São Paulo State
The negative effects of habitat fragmentation on small-mammals are widely recognized. Nevertheless, the intensity of these effects depend on multiple factors such as the pattern of fragmentation, the evaluated scale, the permeability of different types of matrices, and the behavioral plasticity of different groups of species. In this study, we evaluated the

14. Importância da matriz na estrutura de comunidade de besouros carpófilos em paisagem fragmentada / Importance of matrix in the community structure carpophiles beetles in fragmented landscape
Entender como a distribuição e o comportamento de movimento dos animais interagem com a estrutura da paisagem para gerar padrões de distribuição é o principal objetivo da ecologia de paisagens. Neste trabalho, partimos do pressuposto de que a principal fonte de biodiversidade de besouros carpófilos (Coleoptera) na região da Zona da Mata (no estado de

15. Demografia e variação genética de Puma concolor (Linnaeus, 1771) na região nordeste do estado de São Paulo
The northeast area of São Paulo state was originally covered by cerrado and semideciduous forest, but for the last two centuries, it has experienced distinct cycles of human exploitation of its fertile soils. Despite of intensive human activities, large habitat loss and fragmentation of the native vegetation cover, pumas (Puma concolor) still inhabit remnan

16. Avaliação do efeito de borda sobre a vegetação do cerrado stricto sensu inserido em matriz de pastagem / Edge effects on plant community of cerrado sensu stricto inserted into a matrix of pasture
From the Brazilian biomes, the Cerrado has been the most widely and rapidly converted to agribusiness in recent years. The expansion of agricultural frontier over the Cerrado domain resulted in thousands of small fragments embedded in matrices of low similarity, causing a series of negative impacts on the natural ecosystem. Habitat fragmentation is considere

17. Management of lianas in semideciduous forest and cerradão edges, Santa Rita do Passa Quatro, SP / Manejo de lianas em bordas de floresta estacional semidecidual e de cerradão, Santa Rita do Passa Quatro, SP
In São Paulo state, throughout the same climatic zone, semideciduous forests and cerradão patches commonly share the same geographic area. Currently, these two formations are reduced to small fragments, in advanced stage of disturbance. Along with the fragmentation of the forest, there is an increase in ligth incidence at the edges and lianas generally inc

18. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the

19. DIVERSITY, COMPOSITION AND STRUCTURE OF COMMUNITY BATS (MAMMALIA: CHIROPTERA) IN BACKWATER HABITATS CAATINGA E UPLAND FORESTS THE STATE OF SERGIPE. / DIVERSIDADE, COMPOSIÇÃO E ESTRUTURA DE COMUNIDADE DE MORCEGOS (MAMMALIA: CHIROPTERA) EM HÁBITATS DE CAATINGA E BREJO DE ALTITUDE DO ESTADO DE SERGIPE.
Bats are distributed in all Brazilian biomes. Of the 167 species known to occur in Brazil, more than 70 have been recorded in the Caatinga. Despite this diversity, the few studies available for the Caatinga are concentrated at a small number of sites, leaving considerable gaps in the data. A variety of vegetation types are found in the Caatinga. One of the m

20. Small mammals communities in the forest fragments connected by vegetation corridors in the south of Minas Gerais / Comunidades de pequenos mamÃferos em fragmentos florestais conectados por corredores de vegetaÃÃo no sul de Minas Gerais
The forest fragmentation is one of the main threats for the biodiversity. For the fauna, the consequences associated to the forest fragmentation are the original habitat loss, reduction of the fragment size and isolation, which create a number of negative effects over the wild populations, affecting the species richness, the abundance and the animal species

21. 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

22. Aves da praia da Ilha Comprida (Estado de São Paulo, Brasil): uma análise multivariada
As aves foram contadas semanalmente de janeiro 1999 a janeiro 2001 ao longo da praia de Ilha Comprida, sendo esta, uma ilha de barreira localizada ao sul do estado de São Paulo. Para se avaliar a similaridade da composição das aves, os dados das espécies foram arranjados numa matrix com 144 amostras semanais, estudados seguindo um protocolo de análise m

23. Importance of riparian corridors for the fauna: small mammals in forest patches, surrounding matrix and linear elements in an Atlantic forest fragmented landscape / Importância dos corredores ripários para a fauna - pequenos mamíferos em manchas de floresta, matriz do entorno e elementos lineares em uma paisagem fragmentada de Mata Atlântica
This master thesis aimed to evaluate the importance of riparian corridors for the fauna in an Atlantic Forest fragmented landscape. In four systems composed by fragment corridor fragment, we evaluate both the small mammal assemblage (chapter 2) and the habitat quality measured through the vegetation structure and food resources availability for the fauna (ch

24. 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
