A Constituição Brasileira, no seu artigo 225, declara que "todos têm direito ao meio ambiente ecologicamente equilibrado, bem de uso comum do povo e essencial à sadia qualidade de vida, impondo-se ao Poder Público e à coletividade o dever de defendê-lo e...
Access to water reserves in deep soil during drought periods determines whether ornot the tropical moist forests of Amazonia will be buffered from the deleterious effectsof water deficits. Changing climatic conditions are predicted to increase periods of droughtin...
The article synthesizes, maps and updates prominent forest biomass carbon databases to create the first complete set of national-level forest carbon stock estimates. These forest carbon estimates expand on the default values recommended by the...

Severe droughts may alter the reproductive phenology of tropical tree species, but our understanding of these effects has been hampered by confounded variation in drought, light and other factors during natural drought events. We used a large-scale experimental reduction of throughfall in an easterncentral Amazon forest to study the phenological response to drought of an abundant subcanopy tree, Coussarea racemosa. We hypothesized that drought would alter the production and the timing of reproduction, as well as the number of viable fruits.
In Amazonia, the effect of logging on fauna and the ability of reduced-impact logging (RIL) techniques to conserve the ecological integrity of forests is not well understood. In this study, we evaluated the short-term effect of RIL on species richness,...
