1. 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

2. Biomass, nutritional status and ecological anatomy of saplings of tree species of Savannah and Semidecidous Forestof the Wst Paulista / Biomassa, apectos nutricionais e anatomicos de individuos jovens de especies arboreas de Cerradão e Floresta Estacional Semidecidual
O presente abordou aspectos da relação solo-planta, verificando o reflexo das condições físico-químicas e da disponibilidade hídrica do solo de áreas de Cerradão (Ce) e de Floresta Estacional Semidecidual (FES), sobre a anatomia do xilema secundário, sobre aspectos morfológicos (comprimento e a biomassa de parte aérea e de raízes), e sobre o teo

3. Mudanças paleoambientais quaternárias na região de Lagoa Santa, MG, Brasil: a palinologia como subsídio para o entendimento do padrão de ocupação humana.
The objective of this study is to determine the vegetational and climatic history of the Lagoa Santa, Minas Gerais, Brazil since the Last Glacial Maximum (LGM) and relate it with the pattern of human occupancy and to test the Arcaic Gap hypothesis, which suggests that human groups would have migrated to others areas of Brazil, due to dry climates, which woul

4. Os medios e grandes mamiferos de mosaicos em areas de reflorestamentos no Centro-Oeste paulista / The medium and large mammals of mosaics in reflorestations areas in the São Paulo center-west
A riqueza, composição e abundância da mastofauna de médio e grande porte, em duas áreas de reflorestamentos comerciais da Duraflora S/A, no centro-oeste do estado de São Paulo, foram estudadas entre 2005 e 2007. O objetivo deste estudo foi entender como a fauna de mamíferos utiliza áreas de reflorestamento e o potencial de mosaicos com predominância

5. Analise silvigenica em floresta estacional semidecidua e em cerradão no estado de São Paulo / Silvigenic analysis in seasonal semidecidous forest cerradão in the state São Paulo, Brasil
Studies of silvigenic mosaics based on the analysis of tree architecture, presumed to represent reations to the stimulus due to the light entrance in the forest canopy, have been suggested to investigate the mechanisms involved in the construction of tropical forests mosaic patterns. The identification of the eco-units (patches of trees of same architectural

6. Spatial pattern analysis of trees of four forest communities in southeastern Brazil, using Ripleys K function. / Análise dos padrões espaciais de árvores em quatro formações florestais do estado de São Paulo, através de análisses de segunda ordem, como a função K de Ripley.
Tree spatial patterns are influenced by abiotic and biotic environment. Among the main abiotic factors are topography, light, nutrients, soil and water availability. Among biotic factors are density-dependent processes, as intraespecific and interespecific competition, herbivory, pathogens, phenology and seed dispersion. Investigation of tree spatial pattern

7. Propagação vegetativa de especies arboreas a partir de raizes gemiferas : representatividade na estrutura fitossociologica e descrição dos padrões de rebrota de uma comunidade florestal, Campinas, São Paulo
There are little informations about the sprouting of tree species from root buds in Tropical Forests, but its occurrence is associated to events of disturbance. In 0,5ha of a Semidecidous Mesophytic Forest area that has been ofien burnt in Campinas, São Paulo, Brazil (Fazenda Santa Elisa - 22° 54 S; 47° 05 W), it was accomplished the phytossociological st

8. Análise da Vegetação de ARIE Cerrado Pé-de-Gigante (Santa Rita do Passa Quatro, SP). / Vegetation analysis of the Pé-de-Gigante Reserve (southeastern Brazil)
We studied a natural vegetation area, composed mainly by cerrado, with 1269 ha, located at Santa Rita do Passa Quatro municipality, São Paulo State, southeastern Brazil (21 36-44 S e 47 34-41 W). We carried out a floristic survey in 18 field trips, each one with 3 or 4 days, from September 1995 to February 1997. On each existing vegetation types (three cerr

9. Fenologia, biologia floral, mecanismo de polinização e sistema reprodutivo de duas especies simpatricas de Dichorisandra (Commelinaceae)
The comparative study of phenology, floral biology, pollination mechanism and breeding system of Dichorisandra incurva e D. hexandra (Commelinaceae) was undertaken in secondary and semideciduous forest at Campinas, São Paulo, during 1989 to 1991. The species are sympatric, herbaceous, perennials and andromonoecious, with hermaphrodite and functional male fl
