Mercury in birds (aquatic and scavenger) from the Western Amazon
Environmental Research, 2021In the Amazon rainforest, methylmercury (MeHg) is easily biomagnified and bio-accumulated in the aquatic food chain. This unique biome has been studied for occupational and environmental issues related to human health and contamination through fish consumption; however, wildlife studies have not yet addressed fish-eating birds.

Data from the western Amazon area suggest that this dichotomy is an oversimplification. Moving roughly from north to south, Western Amazonian languages fall into four groups: those with (1) systems ...

Fire dynamics in extreme climatic events in western amazon
Environmental Development, 2019Abstract This study aimed to evaluate fire dynamics in ‘extreme’ climatic events of the El Nino Southern Oscillation in the western Amazon in Acre, Brazil. It employed remote sensing products of burned areas, the Enhanced Vegetation Index (EVI), rainfall products, and kernel density to spatialise fire foci. The largest burned area recorded during the

The Late-Quaternary Climate of the Western Amazon Basin
1987Claims that Amazon climates were arid at glacial maxima are without radiocarbon dated evidence to justify them.
