Species Biology

USGS WARC science plays a critical role in informing listing decisions related to the Endangered Species Act. Our work provides insight into the life history, population dynamics, and resource needs of species considered at risk or of management concern, including aquatic mammals, reptiles, amphibians, birds, bats, and fishes.

A Decision Support Tool for Repatriation of Aquatic Fauna: A Case Study Involving the Striped Newt (Notophthalmus perstriatus) at St. Marks National Wildlife Refuge, Florida

The Striped Newt is a small salamander found in xeric habitats (e.g., scrub, sandhill, dry flatwoods) of the lower coastal plain and northern peninsular Florida. Though once considered "common," they are currently a candidate species for federal listing.
