Cascading impacts of anthropogenically driven habitat loss: deforestation, flooding, and possible lead poisoning in howler monkeys ( Alouatta pigra )

摘要: To construct informed conservation plans, researchers must go beyond understanding readily apparent threats such as habitat loss and bush-meat hunting. They predict subtle cascading effects of anthropogenic environmental modifications. This study considered a potential effect deforestation on the howler monkeys (Alouatta pigra) Balancan, Mexico. Deforestation intensifies flooding. Thus, we predicted that increased flooding Usumacinta River, which creates large bodies water slowly evaporate, would produce lead content in soils plants, resulting exposure monkeys. The average levels were 18.18 ± 6.76 ppm 5.85 4.37 plants. However, hair 13 captured was 24.12 5.84 ppm. animals correlated with 2 15 blood traits (lactate dehydrogenase total bilirubin) previously documented to be associated lead. Our research illustrates urgent need set reference values indicating when adverse impacts high occur, whether or natural, evaluate possible primates.
