13. Tree species community diversity: aplication of taxonomic distinctness indices in three forest phytophysionomies in São Paulo State / Diversidade de espécies em comunidades arbóreas: aplicação de índices de distinção taxonômica em três formações florestais do Estado de São Paulo
This research is part of the project Biota / FAPESP, "Tree Species Biodiversity Inventory Methods, and analised floristic structural differences among three areas. In Assis Ecological Station, Forest Savanna area were sampled 102 species, 72 genus and 43 families, 67% of this species were exclusive of this phytophisiognomy. Semideciduous seasonal forest in t

14. Relações solo-vegetação no Parque Nacional da Serra do Cipó, Espinhaço Meridional, Minas Gerais / Soil vegetation relationships in the National Park Serra do Cipó, in Espinhaço Meridional, Minas Gerais
The region of Serra do Rio Cipó, in the southern part of the Serra do Espinhaço, comprises large areas of Cerrado, Atlantic forest, forest islands and one of the richest high-altitude rocky vegetation in Brazil. The ecotonal character between the Cerrado and Atlantic Forest biomes, described in many studies of regional flora and fauna, is one of the factor

15. Mudanças estruturais e florísticas do estrato herbáceo-arbustivo em campo sujo e campo limpo úmido na fazenda Água Limpa-DF após sete anos
Changes in floristic composition and structure of the herbaceous and shrub layer of campo sujo and campo limpo úmido (moist grassland) at the Fazenda Água Limpa, DF were studied between September 1999 and February 2001 and between August 2006 and August 2007. For the phytosociological survey lines were randomly sampled in both areas. The first inventory wa

16. Diversidade beta na floresta ombrófila densa da Amazônia Brasileira
The drivers of the tropical forest beta diversity are still a matter of intense debate. No consensus has been reached; different studies have led to different conclusions. Nonetheless, mapped forest types are frequently used by conservation planners to represent change in floristic composition. The object of this work is to evaluate this practice, and to ver

17. Levantamento floristico da restinga de Maraú, Sul do Estado da Bahia : chave interativa de entradas multiplas para identificação das plantas aquaticas e palustres / Floristic inventory of Marau s "restinga", south of Bahia : interactive multiple-entry key to identification of aquatic and swamp plants
As restingas são áreas com vegetação bem estudada nas regiões sudeste e sul do Brasil, mas ainda faltam dados publicados sobre esses ambientes no norte e nordeste do país. Esses ecossistemas fazem parte do bioma da Mata Atlântica, e muito dessa vegetação já foi perdida durante todos os anos de degradação (da cobertura original restam apenas 7% da

18. Efeito de práticas silviculturais sobre a produtividade primária líquida de madeira, o índice de área foliar e a eficiência do uso da luz em plantios de restauração da Mata Atlântica / Effects of silvicultural practices on wood net primary production, leaf area index and light use efficiency of Atlantic Forest restorations
The purpose of this study was to indentify the most appropriated restoration model by manipulating floristic composition and silvicultural practices, and to understand how the best development was explained by the factors that controls light use and light use efficiency at the canopy. A "Restoration models for Atlantic Forest disturbed lands aiming carbon se

19. DistribuiÃÃo e diversidade de leguminosae em Ãreas de Caatinga no MunicÃpio de Mirandiba â PE / Distribution and leguminosae in Caatinga areas in the municipal district of Mirandiba - PE
The Family Leguminosae is the most representative of the caatinga, comprehend about a third of the wealth of classified species. Due to the importance of Leguminosae in the biome, a floristic inventory was accomplished in the municipal district of Mirandiba-PE. From this list of species we took place the taxonomic treatment and an analysis of similarity of t

20. Avaliação de dados SAR polarimétricos para estimativa volumétrica de florestas tropicais / Polarimetric SAR data analysis for tropical forest volume estimation
In this study it was evaluated the potential of polarimetric synthetic aperture radar (PolSAR) data for the retrieval of timber volume over tropical forests, with sights to identify areas with potential for sustainable timber production. As a secondary focus, it was made a sensitivity analysis of the PolSAR data in detecting floristic and structural variatio

22. Trees, shrubs and climbers of the cerradão of the Bauru Botanical Garden, SP / Arvores, arbustos e trepadeiras do cerradão do Jardim Botanico Municipal de Bauru, SP
The Cerrado Biome contains an immense diversity of species, most of them being endemic. Due to the intense and increasing threats to its natural resources, the Cerrado is currently considered as a priority area for the world-wide biological diversity conservation. In the 1995 workshop ?Conservation basis and the sustainable use of the cerrado areas of São P

23. 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

24. Caracterização e estimativa de biomassa em fitofisionomias de terra-firme da amazônia central por inventário florístico e por textura de imagens simulação do mapsar (Multi-Application Purpose SAR) / Phytophysionomic characterization and biomass estimation of a central amazon upland forest from floristic inventory and texture of images from simulated mapsar (Multi-Application Purpose SAR)
Sob a premissa de que nas florestas de terra firme da Amazônia Central a variação florística e estrutural sofrem influência do relevo e da proximidade da rede de drenagem, este estudo teve o objetivo de: 1) descrever a composição florística e a estrutura horizontal e vertical ao longo da toposequência; 2) desenvolver modelos preditivos de biomassa a
