This is not really OT. Consulting recent cladistic classification shows that frogs are in the Sarcopterygii (along with other amphibians, reptiles, mammals (including good ole _Homo_), birds (smile). Are we cladists on NANFA?
More seriously, this is on topic, because it relates directly to environmental quality, and fish and frogs occur in much of the same habitat. And fish have been shown to be susceptible to some of the same teratogens as amphibians, though I know of no study of fish responses to atrazine.
I do know of studies of economic and industrial concern's responses to reports of pollution.
