13. Atmospheric deposition of key-elements through rain in dense ombrophylous forest in the Serra do Mar State Park / Deposição atmosférica de elementos-chave, através de chuva, em floresta ombrófila densa no parque estadual da serra do mar
Due its altitudinal amplitude, the Serra do Mar State Park (PESM), shelters a variety of physiognomies of the Dense Ombrophylous Forest, such physiognomies are distributed along the level quota in a standard way. This work aims to evaluate the contribution of the moist deposition through the rain, in the distribution of these physiognomies. In order do make

14. Estrutura, diversidade e dispersão em Floresta Ombrófila Densa no Sul da Bahia, Brasil / Structure, diversity and dispersal of Dense Ombrophylous Forest at South of Bahia State, Brazil
The present study aimed to investigate the contribution of a primary remaining forest to biodiversity preservation face its comparison to a secondary forest; add information on Dense Ombrophylous Lowlands Forests at the south of Bahia State, Brazil, Atlantic forest; investigate the importance of zoochoric dispersion during the succession process in two tropi

15. As dinâmicas de Schefflera angustissima (March.) Frodin (Araliaceae) e de Andira anthelmia (Vell.) March. (Fabaceae) na reserva de Morro Grande, São Paulo. / The dynamics of Schefflera angustissima (March.) Frodin (Araliaceae) and Andira anthelmia (Vell.) March. (Fabaceae) in the Morro Grande reserve, São Paulo.
Population dynamics deals with variation in time and space in the density and abundance of populations. The studies about the dynamics of tropical rain forest tree species, in particular, have become popular only about 1970, when the extinction risks for species of economic interest became pressing. Because the Brazilian biomes are being destroyed progressiv

16. Dynamics of gaps / Dinamica de clareiras : comportamento de especies pioneiras e fatores que afetam sua colonização
The Mata Santa Genebra (22°49?45?S 47°06?33?W) is an isolated fragment of the Atlantic Forest. Due to the constant formation of gaps in the interior of the forest it becomes of fundamental importance the knowledge of the dynamics of these gaps for the preservation of the forest. The objectives of this paper were to record and analyze factors which could li

17. A importância das palmeiras arborescentes de grande porte na dinâmica das florestas amazônicas sazonalmente secas.
We investigated and compared the determinants of palm diversity at different spatial scales: along a moisture gradient in a seasonally dry Amazonian forest and using a climatic model comprising the entire Brazilian territory. Climatic hazards seem to strongly determine the distribution of palms, with the relative importance of moisture being highly consisten

18. 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

19. Composição floristica e estrutura da comunidade arborea num gradiente altitudinal da Mata Atlantica
In this study, we describe the changes in soil properties, and in the tree community structure and species composition of the Brazilian coastal Atlantic rain forest along an altitudinal gradient. The study was carried out in the Serra do Mar State Park, São Paulo state, south-eastem Brazil (44048 W e 23022 S). According to the IBGE s c1assification system,

20. Fatores Formadores da Paisagem Litorânea: A bacia do Guaratuba, São Paulo-Brasil / FORMATION FACTORS OF THE COASTAL LANDSCAPE: THE CASE OF THE GUARATUBA WATERSHED, SÃO PAULO, BRAZIL.
This study aims to characterize and correlate elements of the biotic-physical environment, drainage, geology, landform, vegetation cover, soil and land use by means of interpretation of aerial photographs, satellite images and field work. It also aims to test the technique of circular sampling the drainage network for identifying soil mapping units in the Se
