13. 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

14. Penas e medidas alternativas : caminhos, paisagens, encontros, reflexões / Penalties and Alternative Measures: roads, landscapes, meetings, reflections
Imprisonment became the penalty for excellence in contemporary society. However, we observed that the penalties and alternative measures (LDCs) are increasingly used by the Brazilian legal system, being considered by many as a change in the ways of punishing. They seem indisputable, given the horrors experienced these years that the prison was the only legal

15. Landscape and soil regionalization in southern Brazilian Amazon and contiguous areas: methodology and relevance for ecological studies
Soils of a large tropical area with differentiated landscapes cannot be treated uniformly for ecological applications. We intend to develop a framework based on physiography that can be used in regional applications. The study region occupies more than 1.1 million km² and is located at the junction of the savanna region of Central Brazil and the Amazon fore

16. Abundance changes and activity flexibility of the oncilla, Leopardus tigrinus (Carnivora: Felidae), appear to reflect avoidance of conflict
We investigated the density and activity of the oncilla, Leopardus tigrinus (Schreber, 1775), a threatened small cat, in the Brazilian Atlantic Forest, using camera-trap data. We described differences in the activity of individuals occurring alone or in sympatry with larger cats. Oncilla presented low densities (7-13 ind./100 km²) and high flexibility in it

17. A contribuição da Geomorfologia para o conhecimento da fitogeografia nativa do estado de São Paulo e da representatividade das Unidades de Conservação de Proteção Integral / The contribution of geomorphology to the knowledge of native phytogeography in the state of São Paulo and representativeness of the Conservation Units of Integral Protection
The analysis of native vegetation maps of the state of São Paulo elaborated throughout the XIX, XX and XXI centuries shows different possibilities for the interpretation of the state phytogeography, although it also reveals many converging aspects, e.g., forest types in the Atlantic façade adapted to higher moisture than those located in the interior of th

18. Densidade de Rhea americana em três paisagens diferentes no Pantanal da Nhecolândia.
Pecuária em campos nativos constitui uma atividade tradicional no Pantanal brasileiro. Contudo, tem um aumento na substituição de vegetação nativa por pastagens cultivadas de espécies exóticas. As respostas da fauna local em relação a essas transformações ainda são pouco conhecidas. O objetivo do trabalho foi estimar a densidade de ema, Rhea amer

19. 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

20. Parque Nacional do Jaú, Protected Area and Worldwide Natural Heritage in the Brazilian Amazônia: does the articulation of instruments permit better protection? / Parque Nacional do Jaú, Unidade de Conservação e Patrimônio Natural Mundial na Amazônia Brasileira: a articulação de instrumentos permite melhor proteção?
The Parque Nacional do Jaú protected areas by SNUC (National System of Units of Nature Conservation) is located, approximately, 200km northwest of Manaus and it is within the territorial limits of the municipalities of Barcelos and Novo Airão in the state of Amazonas. Being the biggest National Park of Brazil with 2.272.000 hectares, covering the second la

21. Estudo teórico sobre meios de determinação de Áreas de Preservação Permanente (APPs) marginais aos cursos d água através da análise de fatores ambientais no âmbito da bacia hidrográfica: enfoque geomorfológico / Theorical study about the determination of the Permanent Preservation Areas (PPAs) marginal to the water courses through the analysis of the environmental factors in the context of the watershed: geomorphology focus
The Permanent Preservation Areas (PPAs) were imposed by New Brazilian Forest Code in order to ensure the stability of the landscape, water and biotic features. Among the types of PPAs are those which protect the marginal portions of the watercourses, which are currently focuses of environmental conflicts, given its regulatory power that overly restricts the

22. A gren infrastructure to urban areas along the reservoir: The case of Itá(SC) / Uma infraestrutura verde para áreas em urbanização junto a reservatórios: O caso de Itá (SC)
The changes in the landscape and environment and socio-spatial relations in areas affected by the implementation of Power Plants in the Uruguay river watershed creates an opportunity for research on the implementation of a Green Infrastructure for areas along the reservoir, as a fundamental aspect in the study and proposing models of multifunctional landscap

23. Modelos de simulação aplicados à conservação de paisagens fragmentadas da Mata Atlântica brasileira / Simulation models applied to the conservation of fragmented landscapes in the Brazilian Atlantic Forest
Uma efetiva ação de conservação depende de um claro entendimento de como as espécies respondem às características ambientais, em particular à cobertura, configuração espacial e qualidade do habitat. No entanto, nem sempre esses dados estruturais da paisagem estão disponíveis em extensão e escala compatíveis com o planejamento ambiental. Ademais

24. Effects of changes in land use of the Brazilian Amazon on the ecological services provided by EscarabeÃneos (Coleoptera, Scarabaeidae). / Efeitos da alteraÃÃo do uso do solo na Amazonia Brasileira sobre serviÃos ecolÃgicos proporcionados pelos Scarabaeinae (Coleoptera, Scarabaeidae)
Ecosystem services provided by the biodiversity are that ones associated to live organism and that, in last analysis, affect natural process of human interest. Scarabeine dung beetles has been in evidence in the last years in function of the array of services provided, both in natural as in agricultural landscapes. This work aimed to evaluate the effect of l
