Do chão ao céu, monitoramento territorial indígena e a primeira década da ferramenta SOMAI-ACI
A primeira edição do Boletim PROTEJA publicou dados do SOMAI-ACI sobre crimes ambientais em terras indígenas na Amazônia. Entre janeiro de 2021 e novembro de 2023, 761 atividades ilegais foram registradas em 46 terras indígenas, totalizando 33 milhões de hectares...
An alternative approach for mapping burn scars using Landsat imagery, Google Earth Engine, and Deep Learning in the Brazilian Savanna
The Cerrado biome in Brazil is characterized by a mosaic of vegetation types similar to African savanna and has one of the highest levels of biodiversity in the world. Wildfires have historically contributed to shaping the natural vegetation and are now being used...
Starch and lipid storage strategies in tropical trees relate to growth and mortality
Non-structural carbon (NSC) storage (i.e. starch, soluble sugras and lipids) in tree stems play important roles in metabolism and growth. Their spatial distribution in wood may explain species-specific differences in carbon storage dynamics, growth and survival....
Hidden destruction of older forests threatens Brazil’s Atlantic Forest and challenges restoration programs
Understanding the dynamics of native forest loss and gain is critical for biodiversity conservation and ecosystem services, especially in regions experiencing intense forest transformations. We quantified native forest cover dynamics on an annual basis from 1990 to...
Soil properties and bamboo cover drive the structure of the woody plant community along a forest–savanna gradient
Understanding the role of environmental conditions and geographic space on species distributions is a major goal of ecological studies. Here, we investigate the effects of soil properties, a native bamboo (Actinocladum verticillatum (Nees) McClure ex Soderstr)...
Model-Based Estimation of Amazonian Forests Recovery Time after Drought and Fire Events
In recent decades, droughts, deforestation and wildfires have become recurring phenomena that have heavily affected both human activities and natural ecosystems in Amazonia. The time needed for an ecosystem to recover from carbon losses is a crucial metric to...
Agricultural land-use change alters the structure and diversity of Amazon riparian forests
Riparian forests play key roles in protecting biodiversity and water resources, making them priorities for conservation in human-dominated landscapes, but fragmentation associated with expanding tropical croplands threatens their ecological integrity. We compared...
