13. Tree species of South America central savanna: endemism, marginal areas and the relationship with other biomes
Biological knowledge is important for guidance of conservation polices. In the Cerrado, an extremely diverse biome, the last synthesis of floristic knowledge has more than ten years. To understand the progress on the information, our aim was quantify the tree species of the Cerrado, and assess their distribution. We compiled 167 inventories and rapid surveys

14. Bryophyte flora in upland forests at different successional stages and in the various strata of host trees in northeastern Pará, Brazil
In the northeastern region of the Brazilian state of Pará, approximately 90% of the forested areas are secondary forests. Secondary forests are interesting areas for floristic studies aimed at determining the effects that clear-cutting has on bryophyte communities. The aim of this study was to compare upland forests at different successional stages and the

15. Padrões florístico-estruturais, de diversidade alfa e de distribuição potencial de espécies arbóreas entre os domínios do cerrado e da Amazônia / Floristic-structural, alpha diversity and potential distribution patterns of tree species between cerrado and Amazonian domains
Na América do Sul, há pouco conhecimento sobre as relações florísticas entre Domínios de florestas e savanas. Considerando os Domínios do Cerrado e Amazônico no Brasil e a área de transição entre eles, investigamos os padrões de similaridade e de gradientes (Capítulo 1), de diversidade alfa (Capítulo 2) e de distribuição geográfica potencial

16. Colonização de ambientes abertos do cerrado por espécies arbóreas florestais: a ação facilitadora de Bowdichia virgilioides Kunth / Colonization of cerrado open habitats by forest tree species: the Bowdichia virgilioides Kunth facilitator action
Esta dissertação trata do estudo de uma comunidade de espécies arbóreas florestais colonizadoras de núcleos de Bowdichia virgilioides em uma área de cerrado sentido restrito da Estação Ecológica do Panga. O estudo foi contextualizado, na introdução geral, destacando os principais conceitos teóricos abordados e a situação da Estação Ecológica

17. Corticolous cyanobacteria from tropical forest remnants in northwestern São Paulo State, Brazil
Cyanobacteria are common in aquatic environments but are also well-adapted to terrestrial habitats where they are represented by a diversified flora. The present study aimed to contribute to our taxonomic knowledge of terrestrial cyanobacteria by way of a floristic survey of the main components of corticolous communities found in seasonal semideciduous fores

18. The tree-shrub vegetation in rocky outcrop cerrado areas in Goiás State, Brazil
We describe the floristic composition of the tree-shrub vegetation in 10 areas of rocky outcrop cerrado in Goiás State, Brazil. Ten 20×50m plots (totaling 1ha) were established and all of the individuals with diameters at 30cm above soil level (DB30) ³5cm were included in the sampling. Comparative analyses of the flora were realized using similarity indic

19. Florística e estrutura da comunidade arbustivo-arbórea em florestas naturais e restauradas com Araucaria angustifolia (Bertol.) O. Kuntze no estado de São Paulo, Brasil / Floristic composition and structure of the tree-shrub layer in natural and restored forests with Araucaria angustifolia (Bertol.) O. Kuntze on São Paulo state, Brazil
A Floresta Ombrófila Mista vem sofrendo desde meados do século XIX uma drástica redução territorial no Brasil. Estima-se que esta fitofisionomia ocupe atualmente cerca de 1 a 4% da sua cobertura original. Além disso o conhecimento acerca da estrutura, composição e dinâmica das florestas de araucária paulistas ainda é incipiente, tornando a conserv

20. 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

21. Centrolobium tomentosum: macro-and microscopic diagnosis of the leaf and stem
Centrolobium tomentosum Guillemin ex Benth., Fabaceae, known as "araribá-rosa", is a large tree that is widespread throughout Brazil. The bark of its stem is used in folk medicine as an astringent and the leaves are employed as a poultice for wounds and bruises. The aim of this study was to contribute to the pharmacognostic quality control of this medicinal

22. Estrutura populacional de Aspidosperma polyneuron Muel. Arg. (Apocynaceae) em fragmento florestal do baixo Rio Tibagi por marcadores AFLP
The XXI century is characterized by intense fragmentation of tropical forests around the word which is responsible for environmental degradation, climate changes and loss of biodiversity. Such process is the focus of many studies that intend, primarily, to identify the effect of devastation in the gene pool of species that occupy degraded areas. The Tibagi R

23. Sucessão secundária em áreas de Mata Atlântica de Pernambuco : mudanças florísticas e estruturais
Secondary forests have been considered as priority areas for conservation in tropical regions due to their possible role as buffer zones. They serve as habitats for plants and animals coming from destroyed mature forests and as corridors between forest fragments. They also have the capacity to accumulate biomass and nutrients at high rates, to maintain bioge

24. Padrões florísticos e estruturais das Florestas Estacionais Semideciduais do Triângulo Mineiro, MG / Floristic and structural patterns of semideciduous seasonal forests of Triângulo Mineiro, MG
The semideciduous seasonal forests (SSF) of southeastern Brazil have a high floristic diversity, accompanied by a high beta diversity, even between nearby fragments. However, nowdays these forests have been represented by a large number of small fragments, a landscape pattern typical for this region. In addition to the processes related to fragmentation, the
