Threats to Brazilian crocodilian populations

Abstract

Brazilian crocodiles are threatened by gold mining and related mercury- and lead-contamination of animals and their habitat, deforestation, increasing use of land for agriculture and destructive forestry, increased human incursions, and commercial and subsistence hunting for skins and meat. Contaminated meat is consumed by local people and miners, and meat and skins are exported to global markets. Already depleted black caiman Melanosuchus niger populations are seriously affected.
