A quarter of the deforested Amazon has regrown as secondary tropical forest and yet the climatic importance of these complex regenerating landscapes is only beginning to be recognised. Advances in satellite remote-sensing have transformed our ability to detect and...
REUTERS.: Amazon deforestation drops sharply: Brazil govt. Bsb, Agosto, 2007. You can reed the article here - http://reut.rs/e0QPQCArticle produced by Reuters, in August 2007, says that the deforestation of the Amazon rain forest in Brazil fell by about a third in...
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,...
Here we report that protected areas in the Amazon basin—the central feature of prevailing conservation approaches—are an important but insufficient component of this strategy, based on policysensitive simulations of future deforestation.
Understory fires, which burn the floor of standing forests, are one of the most important types of forest impoverishment in the Amazon, especially during the severe droughts of El Niño–Southern Oscillation (ENSO) episodes. However, the authors are aware of no...
The current annual rates of tropical deforestation from Brazil and Indonesia alone would equal four-fifths of the emissions reductions gained by implementing the Kyoto Protocol in its first commitment period, jeopardizing the goal of Protocol to avoid “dangerous...
