| O presente trabalho compara a composição e estrutura de assembléias vegetais de fragmentos florestais, com diferentes características em relação ao tipo de propriedades rurais do entorno, tamanho e histórico de uso, com uma área localizada dentro de uma unidade de conservação (área controle), na bacia do rio Guapiaçu. Em cada fragmento foram delimitadas duas parcelas de 50 x 100m, na mesma orientação sudoeste, no interior das quais foram medidos os DAP (Diâmetro Acima do Peito) e altura de todos indivíduos com DAP ≥ 5 cm e identificados até o menor nível taxonômico possível. A densidade, área basal total, riqueza e diversidade foram calculados. As assembléias foram comparadas quanto aos seus valores diâmétricos e proporção de indivíduos em classes de... |

| Swamp forests are associated with soils that are saturated or inundated because of a high water table. In Brazil, little is known about the plant ecology of such forests. In this paper, we aimed to describe the phytosociological structure of the tree layer of swamp forests in Restinga de Jurubatiba National Park, in the northern part of the state of Rio de Janeiro, and to evaluate the floristic similarities between these forests and some other possibly related types of vegetation formations in Brazil. The sampling included 84 species, within 62 genera and 34 families. The Shannon diversity index was 3.42, and the Shannon evenness index was 0.77. The forests studied showed an oligarchic structure; Tapirira guianensis, Calophyllum brasiliense and Protium... |

| Abstract Studies of the vegetation on islands off the coast of southeastern Brazil are still very scarce, despite their importance for assessing, managing, and conserving insular biodiversity. We present here a list of the vascular flora of Queimada Grande Island (QGI; 24°29′10″ S, 46°40′30″ W, 57 ha, 33.2 km from the coast) in southeastern Brazil and describe its phytophysiognomies. The island is covered mainly by Atlantic Forest (Dense Ombrophilous Forest), as well as with rock outcrop and anthropogenic vegetation with herbaceous-shrub phytophysiognomies. QGI showed relatively low species richness (S = 125) when compared to other Brazilian coastal islands. Herbaceous (52) and climbing species (31) predominated on QGI. The richest families were Fabaceae... |
