Amphibians

Amphibians represent an important part of aquatic and terrestrial ecosystems in the Greater Yellowstone Ecosystem. 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 due to their sensitivity to a variety of factors such as pollution, introduced species, drought, habitat destruction, and disease. Amphibian populations may be affected by these factors and exhibit measurable changes in site occupancy, distribution, abundance, species richness, and increases in both disease occurrence and malformations. These changes in amphibian populations have cascading effects on other aspects of the ecosystem, such as predator, prey and competitor populations, energy flow and nutrient cycling.
