"This is one of the main factors in the shrinking of the rain forest," said Carmen Josse, director of the Fundacion Ecociencia in Quito. A practice common in Brazil, Peru, Ecuador and Bolivia is for farmers to set fires in the dry season to clear the undergrowth in deforested areas. Ho...
Naturally occurring wildfires are rare in moist rainforests but repeated droughts and forest degradation have increased the occurrence of wildfires in the Amazon region2,5,60,61. The more intense a fire (i.e., the more heat it releases), the higher the injection height, where horizontal winds...
Unfortunately, getting into the Amazon rainforest and collecting information are very difficult. To study past climate, scientists need to look at fossilized pollen, kept in lake mud. Going back to the last ice age means drilling deep down into lake sediments (沉淀物)which requires specialized ...
government in 2019 (Operación Mercurio). Yet, our results suggest that the very forest complexity that is the basis for Amazonian biodiversity makes this region highly vulnerable to enhanced Hg loading and storage on the landscape from ASGM-related Hg emissions, leading to the highest ever reporte...
Forest conservation is essential for action on climate change and biodiversity loss. Forest loss and degradation are increasing around the world, including
Amazon rainforest is facing several threats due to anthropogenic activities causing loss of habitat, species, and ecosystem functions. However, several are
The perceived scale of the Amazon blazes received global attention this summer. However, international concerns raised at the time were countered by the Brazilian Government, which claimed the fire situation in August was ‘normal’ and ‘below the historical average’. ...

Smoke from vegetation fires affects air quality, atmospheric cycling, and the climate in the Amazon rain forest. A major unknown has remained the quantity of long-range transported smoke from Africa in relation to local and regional fire emissions. Here we quantify the abundance, seasonality, and...
Moreover, severe droughts are expected to have a greater impact on Amazon ecosystems compared with the Cerrado, since forest species are more sensitive to desiccation (Meir et al., 2015) and less adapted to intense droughts. Our study quantifies the contributions of Conservation Units (CUs), ...
