Department of Interior Finds Atrazine and Other Pesticides Is Causing Local Frog Extinctions from @NRDC's blog:

While northern leopard frogs may be exposed to pesticides in a number of ways, they are most significantly exposed to pesticides when run-off from agricultural and urban areas reaches occupied habitats. Exposure to pesticide run-off can influence parasitic community structure and seasonal recruitment in northern leopard frogs (King et al. 2008, p. 20). Berrill et al. (1997, p. 243) found that tadpoles (including northern leopard frog tadpoles) are extremely sensitive (i.e., they experience analysis and death) to exposure of one pesticide at a time; pesticides in combination likely have more severe effects. Ouellet p. 97) examined northern leopard frogs in agricultural and non-agricultural ponds in Quebec and found that rogs in the agricultural ponds had a variety of hind limb malformations. The authors identified agricultural pesticides as a potential causal agent. Pestici...
