A new species of frog recently announced itself to scientists studying amphibians in the area surrounding New York City. The marshes and wetlands of the tristate area have long been recognized as home to spotted leopard frogs; several species have already been described in the region. But when researchers heard this frog's unusual vocalization, they suspected that it was not one of the known types of leopard frogs. Specimens were collected in northern New Jersey, Staten Island, and Connecticut, and DNA analysis soon proved that the frog with the unique croak was not a hybrid of the more common Northern and Southern Leopard Frogs, but a third, undescribed species with its own evolutionary lineage. As amphibians are highly sensitive to fluctuations in their environment, those living in densely populated urban areas are especially vulnerable. Accurate knowledge of species identities and distribution will help to preserve biodiversity and manage ecosystems in regions with high levels of human development.
