Because amphibians have a biphasic (two phase) life cycle, permeable
skin, and are exposed to pollutants and other environmental stresses from their
environment on a daily basis, they can serve as an early warning indicator, or
"bio-indicator," of potential drastic changes in the ecosystems.
There has been a worldwide decline in amphibian populations since 1989 and
amphibian populations have been found showing a variety of morphological mutations.
These may be an indication of declining environmental conditions. KanCRN is
actively encouraging research to investigate the factors leading to amphibian
population declines by conducting call surveys in the spring of each year.
