Acris crepitans blanchardi and Rana pipiens
have disappeared from many historical localities in northwestern Indiana.
Other lipophilic chemicals in runoff may also play a role--recent studies found that exposing Rana pipiens
tadpoles to extracted compounds from semipermeable membrane devices in freshwater ponds could cause malformation in the presence of UV radiation (Bridges et al.
1996) and to alter the rate of metamorphosis in Rana pipiens
as well as in X.

These sites have produced approximately 4000 amphibian captures of six different species: one salamander (Ambystoma tigrinum) and five frogs (Rana sylvatica, Rana pipiens
, Bufo cognatus, Pseudacris maculata, and Scaphiopus bombifrons).
