Amphibians are an important part of greater Yellowstone's aquatic and terrestrial ecosystems. They are prey for many fish, reptile, bird, and mammal species and, in turn, they eat a wide variety of vertebrate and invertebrate species. Amphibians serve as indicators of environmental change because of their sensitivity to factors such as pollution, introduced species, drought, habitat destruction, and disease. Amphibian populations that are affected by one or more of these stresses may exhibit increased deformities and changes in site occupancy, distribution, abundance, and species richness. These changes in amphibian populations have cascading effects on other aspects of the ecosystem.
