USGS and Iowa State University scientists quantified Northern Leopard frog exposure to pesticides in aquatic and terrestrial habitats using a novel combination of radio telemetry and passive sampling techniques to better understand factors affecting frog health and survival in agricultural landscapes. The results of this newly published research can inform conservation strategies by providing information about when and where the frogs are most likely exposed to pesticides. This unique approach can be utilized in other land-use settings and with other amphibian species to better understand if contaminant exposure affects growth, development, fitness, and survival.
