Abstract
Abstract During 10-weeks, visual-encounter surveys were conducted on the Georgetown salamander Eurycea naufragia at a spring pool in Williamson County, Texas. There was no significant difference in number of salamanders observed or percentage of objects used as cover between surveys in mornings and afternoons. Number of salamanders detected and percentage of objects used as cover were not correlated significantly with any environmental variable that was assessed. These results suggest that visual-encounter surveys conducted during daylight hours are not biased by time of day.
