Forest Recovery Following Pasture Abandonment in Amazonia: Canopy Seasonality, Fire Resistance and Ants

Tropical forests are important regulators of the flux and storage of carbon, water, and energy in the Biosphere, and they are the habitat of more than three-fourths of the world’s plant and animal species. These ecosystems are also undergoing rapid conversion through pasture formation, shifting cultivation and timber highgrading as the people of tropical nations turn to forestlands for sustenance and wealth.

Povos indígenas e comunidades tradicionais que vivem numa floresta pública não destinada da Amazônia podem encontrar na regularização do território um apoio para proteção da terra e garantia de direitos. Mesmo que essa caminhada tenha desafios, existem vários...

Agricultural land-use change alters the structure and diversity of Amazon riparian forests

Riparian forests play key roles in protecting biodiversity and water resources, making them priorities for conservation in human-dominated landscapes, but fragmentation associated with expanding tropical croplands threatens their ecological integrity. We compared...

Effects of partial throughfall exclusion on the phenology of Coussarea racemosa (Rubiaceae) in an east-central Amazon rainforest

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.
