1. Termite assemblages (Blattodea: Isoptera) in a habitat humidity gradient in the semiarid region of northeastern Brazil
ABSTRACT We compared the termite assemblages of different ecosystems in a humidity gradient. Three areas were sampled: (i) a humid montane forest; (ii) a hillside forest where shaded coffee (Coffea arabica Linnaeus, 1753) is cultivated; (iii) a seasonally dry forest (Caatinga). Active collection protocols were employed in each area during the dry and rainy s

2. Gradientes edáficos e sua relação com as fitofisionomias do semi-árido meridional brasileiro / Edaphic gradients and their relationship with the vegetation types of semi-arid southern Brazil
The semi-arid region in Brazil represents a significant territorial extension, where the climate is markedly seasonal, with low rainfall, high evapotranspiration and higher temperatures. Its southern portion comprises the northern boundary between the states of Minas Gerais and Bahia. This region is dominated by dry forest vegetation type, however, different

3. Elevational gradient on the arboreal flora on Moutain Cuscuzeiro, Ubatuba (SP) : a phytogeographic, phytosociologic and floristic analysis / A vegetação arborea em um gradiente altitudinal no Morro Cuscuzeiro, Ubatuba (SP) : uma analise floristica, fitossociologica e fitogeografica
The classification and delimitation of different vegetational formations into a phytogeographic system in Brazil has been a challenge to ecologists, botanists, and phytogeographers. The current distribution of these formations is related to historical process of land use and complex environment gradients, occurring in horizontal (latitude, longitude and edaf

4. Distribuição de espécies de Melastomataceae juss. em três fisionomias contíguas do bioma Cerrado na Estação Ecológica de Águas Emendadas (Planaltina - DF)
O estudo foi realizado na porção inicial do Córrego Vereda Grande na Estação Ecológica de Águas Emendadas (Planaltina - DF) entre novembro (2005) e dezembro (2006), objetivando avaliar a zonação de espécies de Melastomataceae em relação ao gradiente de umidade na eqüência de ambientes Cerrado Típico (CT), Campo Sujo (CS) e Vereda (VE), em 10 l

5. Geographic patterns of the fruit traits from Atlantic forest: environmental and ecological relationships of the dispersal modes / Padrões geográficos das síndromes de dispersão e características dos frutos de espécies arbustivo-arbóreas em comunidades vegetais da Mata Atlântica
Fruits with seeds dispersed by vertebrates are very frequent in tropical forests. However, there is a great variation in the proportion of zoochoric fruits when different communities are compared. Atlantic forest might have between its species, similar proportion of biotic dispersal modes comparing with other tropical forest communities but, its communities

6. Influencia da variação fisionomica da vegetação sobre a composição de aves frugivoras na Mata Atlantica
Due to the alarming rate of deforestation in tropical forests, a better understanding on the organization of biological communities is needed, specifically regarding the interactions between birds and plants. Although this aspect is not often included among the top priorities for biodiversity conservation, it must be considered an important of effort in the
