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...

Hardwood bottomland restoration is an expanding conservation practice in the southeastern United States. Understanding relative flood tolerance of bottomland seedlings is important to restoration success. Thus, we related height and diameter of Quercus phellos, Q. nuttallii, and Q. lyrata to elevation gradient in a 6-ha west Tennessee bottomland. We planted 3,771 seedlings from January-March 2004 in a randomized design such that all species had spatial representation across elevation gradients. Seedling height and root-collar diameter were measured in October and November 2004, and related...
