In studies of deformed leopard frogs in Midwestern and Northeastern states, scientists at the USGS National Wildlife Health Center did not find parasites (metacercariae) in the limb buds of the developing tadpoles and they have not yet found evidence that a parasite influenced limb development in these tadpoles.
The remaining relict leopard frog populations suffer from low genetic variation and are very vulnerable to extinction due to population fragmentation and the small size and isolation of their remaining habitat.

The relict leopard frog was one of the first North American amphibians thought to have become extinct.
One hot summer day in 1995 eight middle school children planning a simple study of wetland ecology began collecting leopard frogs from a small pond near Henderson, Minn.

The agents were administered subcutaneously into the dorsa lymph sac of Northern leopard frogs, Rana pipiens, (for methods, see1,2) and analgesic effectiveness was assessed for the ability of test agents to reduce the behavioral response to a dilute, weak acid noxious stimulus.
