A jornada do Rio Nhandé: em busca da proteção da floresta e do futuro da comunidade
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...
New Observations on Cebus kaapori (Queiroz, 1992) in eastern Brazilian Amazonia
Cebus kaapori is a new species of untufted capuchin monkey recently described by Queiroz (1992). It is similar to Cebus olivaceus, and data from molecular studies indicate that this new form is differentiated from C. olivaceus at no more than the subspecific level...
Positive Feedbacks in the Fire Dynamic of Closed Canopy Tropical Forests
The incidence and importance of fire in the Amazon have increased substantially during the past decade, but the effects of this disturbance force are still poorly understood. The forest fire dynamics in two regions of the eastern Amazon were studied. Accidental...
Large-scale impoverishment of Amazonian forests by logging and fire
Amazonian deforestation rates are used to determine human effects on the global carbon cycle and to measure Brazil's progress in curbing forest impoverishment. But this widely used measure of tropical land use tells only part of the story. Here we present field surveys of wood mills and forest burning across Brazilian Amazonia which show that logging crews severely damage 10,000 to 15,000 km2 yr−1 of forest that are not included in deforestation mapping programmes.
Forest Fire Prediction and Prevention in the Brazilian Amazon
Muitas florestas na Amazônia são capazes de resistir às queimadas durante a estação seca comum em aproximadamente metade da bacia. Entretanto, as florestas tolerantes à seca perdem sua resistência ao fogo quando submetidas às operações de exploração madeireira....
Floresta Amazônica: Dinâmica, Regeneração e Manejo
A obra contém uma coletânea de trabalhos que relatam assuntos sobre a região da Amazônia Brasileira como: recuperação florestal, conservação da floresta nativa em ambientes mais simples, exploração madeireira. Dentro deste cenário, estudos que buscam entender a...
Deep Soil Moisture Storage and Transpiration in Forests and Pastures of Seasonally-Dry Amazonia
To assess the impacts of land-use changes on plant-available water (PAW) and evapotranspiration (ET), volumetric water content (VWC) was measured to 8 m beneath three, adjacent ecosystems for four years (1991–1994). Estimates of PAW, ET, and deep drainage were...
