Amazônia em Chamas nº 12 – entendendo a relação entre o fogo e desmatamento em 2023
Apesar da redução de 50% no desmatamento na Amazônia, a pior seca em 125 anos aumentou o fogo em outras áreas do bioma, elevando a área queimada total para 10 milhões de hectares, 36% a mais do que em 2022. Dados foram publicados Nota Técnica Amazônia em Chamas nº...
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...
