Relict leopard frogs, Rana [ Lithobates ] onca , once thought extinct, are confined to five known warm spring habitats along the Colorado River in Nevada. We evaluated the effects of temperature on developmental time, survival to metamorphosis and body mass at metamorphosis of captive-bred tadpoles. Highest survival and shortest time to metamorphosis were obtained at temperatures between 25 and 30°C, indicating that temperature is an important consideration for reintroduction site selection.
