Description Distribution and Habitat Country distribution from AmphibiaWeb's database: United States U.S. state distribution from AmphibiaWeb's database: Wyoming
Life History, Abundance, Activity, and Special Behaviors Trends and Threats Local and broad scale population declines are due to depredation, mostly due to introduced predators. Recent investigations involving implanted radio transmitters suggested predator attack primarily from mustelids (Parker 2000). Still, it is not often that naturally occurring predator-prey relationships are the cause of extinction of an entire population. The original decline may be due to a chytrid fungus, Batrachochytrium dendrobatidis, which has been implicated in amphibian declines worldwide. The current population at Mortenson Lake is infected with the fungus, and has been since 1989 (USFWS 2000). Translocation results on A. baxteri is discouraging (Seigel 2001). Possible reasons for amphibian decline Prolonged drought Comments Hear calls at the Western Sound Archive.
