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...
Effects of an experimental drought and recovery on soil emissions of carbon dioxide, methane, nitrous oxide, and nitric oxide in a moist tropical forest
Changes in precipitation in the Amazon Basin resulting from regional deforestation, global warming, and El Niño events may affect emissions of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and nitric oxide (NO) from soils. Changes in soil emissions of...

Modeling forest understory fires in an Eastern Amazonian landscape
Forest understory fires are an increasingly important cause of forest impoverishment in Amazonia, but little is known of the landscape characteristics and climatic phenomena that determine their occurrence. We developed empirical functions relating the occurrence...
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...
