The Mid-Atlantic Center for Herpetology and Conservation is pleased to announce the launch of the Pennsylvania Amphibian & Reptile Survey (abbreviated as PARS), a new amphibian and reptile atlas created through a partnership with the Pennsylvania Fish & Boat Commission. This ten-year project (2013-2022) is calling on Pennsylvania’s naturalists, amateur and professional herpetologists, and nature enthusiasts in general, to join the increasing ranks of citizen scientists collecting important observations for science and resource agencies. The amphibians and reptiles of Pennsylvania need your help.
From Penn State News, "Study suggests link between agricultural chemicals and frog decline":
Around the world, amphibian populations are in decline, and scientists have not been able to figure out why. Now a study of leopard frogs in Pennsylvania has identified a possible culprit, and the ramifications are troubling, according to a Penn State ecologist.
Research conducted primarily at Penn State's Russell E. Larson Agricultural Research Center at Rock Springs in the summer of 2007 — described in a recently published article in the journal Nature — suggests that chemical pollution can increase often-deadly trematode (parasitic flatworm) infections in a declining amphibian species.
"Like canaries used to gauge the safety of air in coal mines, amphibians are thought to be the 'canaries' in our freshwater environments, and reductions in their health can warn that subsequent species declines might be in store," says Hunter Carrick, associate professor of aquatic ecology in Penn State's College of Agricultural Sciences, who was one of the lead investigators in the study.
