Comparison of Anuran Call Survey Durations in Tennessee Wetlands

Anuran breeding call surveys are widely used to document species richness and relative abundance. Call survey protocols used by the North American Amphibian Monitoring Program are five minutes in duration. However, recent studies have suggested that 5-minute call surveys may not be long enough to accurately estimate species richness or relative abundance. Therefore, we tested whether anuran species richness and relative abundance differed between 5- and 10-minute breeding call surveys. We conducted 344 call surveys from March-August 2005 and 2006 at eight wetlands on the Cumberland Plateau...
