Climate benefits of Amazon secondary forests—recent advances and research needs
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...
Nitrogen and phosphorus limitation of biomass growth in a tropical secondary forest
Understanding secondary successional processes in Amazonian terrestrial ecosystems is becoming increasingly important as continued deforestation expands the area that has become secondary forest, or at least has been through a recent phase of secondary forest...
Nutrient loss and redistribution after forest clearing on a highly weathered soil in Amazonia
Over the past three decades, tropical forest clearing and burning have greatly altered the Amazonian landscape by increasing the cover of pastures and secondary forests. The alteration of biogeochemical processes on these lands is of particular interest on highly...
A selva como laboratório: Pesquisadores preparam queimada gigante para saber até que ponto a mata pode resistir
Matéria da revista Veja (online) divulga experimento realizado por cientistas de quatro insituições – Instituto de Pesquisa Ambiental da Amazônia, Centro de Pesquisa Woods Hole Universidades de Yale e Stanfort, dos Estados Unidos.
Diet of a muriqui group (Brachyteles arachnoides) in continuous primary forest
The feeding behaviour of a group of free-ranging muriquis (Brachyteles arachnoides) was monitored in the 380 km2 Carlos Botelho State Park (PECB), between February 1992 and November 1993. Scan sample data indicated that 59.1% of feeding time was devoted to fruit,...
Moisture and substrate availability constrain soil trace gas fluxes in an eastern Amazonian regrowth forest
[1] Changes in land‐use and climate are likely to alter moisture and substrate availability in tropical forest soils, but quantitative assessment of the role of resource constraints as regulators of soil trace gas fluxes is rather limited. The primary objective of...
Collective Action Without Collective Ownership: The Role Of Formal Logging Contracts In Community Associations On The Brazilian Amazon Frontier
Neste trabalho os autores utilizam-se de dados socioeconômicos sobre os colonos para estudar contratos entre pequenos produtores de madeira e a indústria madeireira.
