Relatório de Atividades 2024
O ano de 2024 nos deu alguns motivos para seguir acreditando que é possível reverter um cenário de colapso global. Vimos a redução do desmatamento continuar na Amazônia e o Cerrado começar a acompanhar essa tendência. Mas é preciso mais que isso. Passamos pelo ano...
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.
The economic cost of the use of fire in the Amazon
The objective of this study is to investigate the cost of the use of fire in the Amazon. Burnings are commonplace in the Amazon production process and contribute towards the region’s agricultural expansion. Fire is used by farmers in the land preparation process...
Amazon drought and its implications for forest flammability and tree growth: a basin-wide analysis
Severe drought in moist tropical forests provokes large carbon emissions by increasing forest flammability and tree mortality, and by suppressing tree growth. The frequency and severity of drought in the tropics may increase through stronger El Niño Southern...
Simulating the response of land-cover changes to road paving and governance along a major Amazon highway: the Santarém–Cuiabá corridor
The spatial distribution of human activities in forest frontier regions is strongly influenced by transportation infrastructure. With the planned paving of 6000 km of highway in the Amazon Basin, agricultural frontier expansion will follow, triggering potentially...
