Resumo: | ABSTRACT Amphibians are excellent bioindicators because they are sensitive to chemical pollution and can indicate ecosystem changes due to the presence of or exposure to chemical compounds. Here we report evidence of the impact of herbicides, including glyphosate, on amphibians in a locality in the central Brazilian Amazon and compare it with data from other biomes in Brazil. We observed malformations in three species of Leptodactylus and local extinctions of Scinax ruber and Rhinella marina from reproductive sites close to an area where herbicides had been applied. The observations in the Amazon are similar to reports from Brazil’s Atlantic forest on morphological anomalies and mortality in amphibians exposed to herbicides. We warn of the threat of expanding crops for the production of biofuels in the Amazon due to their cultivation being associated with agrochemicals, including glyphosate, posing a threat to the biodiversity of the Amazon biome.
