Amphibian News
Who would have predicted that an undescribed, cryptic species of frog would be uncovered within New York City? In a recent paper Feinberg and associates describe Rana kauffeldi, a species previously confused with R. pipiens and R. sphenocephala. The new species has a narrow lowland distribution, from northern New Jersey to central Connecticut (including Staten Island), but based on calls, it might occur as far south as North Carolina. Its unique call gave it away, and genetic data confirmed its distinctiveness. (Listen to its call here.) Discoveries such as this are critical in efforts to preserve biodiversity, because few sites remain in the heavily urban area the species occupies.
