Produtividade primária líquida e sazonalidade da temperatura e precipitação são indicadoras da riqueza de espécies das libélulas na Amazônia
Várias hipóteses foram propostas para explicar os mecanismos que geram padrões de riqueza de espécies temporais e espaciais. Quatro hipóteses comuns foram testadas (água, energia, heterogeneidade climática e produtividade primária líquida) para avaliar quais...
Long-term post-fire resprouting dynamics and reproduction of woody species in a Brazilian savanna
Resprouting is an efficient life history strategy by which woody savanna species can recover their aboveground biomass after fire. However, resprouting dynamics after fire and the time it takes to start producing flowers and fruits are still poorly understood,...
O ar é insuportável – Os impactos das queimadas associadas ao desmatamento da Amazônia brasileira na saúde
Estendendo-se por quase metade do território brasileiro e abrangendo nove de seus estados, a região amazônica é o lar de mais de 20 milhões de brasileiros. Desde 1985 – quando o governo começou a monitorar o desmatamento na Amazônia –, mais de meio milhão de...
Woody aboveground biomass mapping of the Brazilian savanna with a multi-sensor and machine learning approach
The tropical savanna in Brazil known as the Cerrado covers circa 23% of the Brazilian territory, but only 3% of this area is protected. High rates of deforestation and degradation in the woodland and forest areas have made the Cerrado the second-largest source of...
Reconstructing three decades of land use and land cover changes in Brazilian biomes with Landsat archive and Earth Engine
Brazil has a monitoring system to track annual forest conversion in the Amazon and most recently to monitor the Cerrado biome. However, there is still a gap of annual land use and land cover (LULC) information in all Brazilian biomes in the country. Existing...
Smoke pollution’s impacts in Amazonia
Brazil’s Amazon region is undergoing a period of environmental setback, during which large infrastructure projects are being pushed forward and environmental protection is being reduced. One of these projects is the reopening of Highway BR-319, which was built in...
