13. Sub-regiões fitogeográficas da floresta atlântica entre as bacias dos rios São Francisco e Uruguai baseadas na análise dos padrões de distribuição espacial da flora arbórea e do clima / Phytogeographic subregions of the Atlantic Forests between São Francisco and Uruguay River basins based on the analysis of spatial distribution patterns of the tree flora and climate
The spatial variation in the composition of the tree flora of some Atlantic forest areas distributed in the East Atlantic basins, Southeastern and Southern Brazil, extended to Paraguay and Argentina, was investigated under four main aspects: (1) to evaluate the level of floristic differentiation of tropical and subtropical forests along their latitudinal, al

14. Determinants of geographical distribution in Atlantic Forest species of Drymophila (Aves: Thamnophilidae)
Climate, altitude and vegetation are usually considered as limiting factors in plant and animal distribution. Among vertebrates, climate and vegetation have consistently been considered as major determinants of geographical distributions. Here we analyzed the role of climate and the vegetation in limiting the geographical range of Atlantic Forest species of

20. Sistema integrado de informações para preservação de recursos hídricos em unidades de conservação / Integrated information system for protecting water resources in protected areas.
The increasing demand of mankind by use of water quality and sufficient volume to meet their needs in their different uses, shows that water resources must be managed and preserved. A watershed is the physical unit that integrates the entire flow of water that makes up the hydrological cycle, but its use is being carried out in a disorderly way, without comp
