Faculty Advisor: Peter Meylan

ABSTRACT

Radio telemetry is a proven tool to collect detailed information on movements and internal body temperatures of vertebrates. This method was used to study Elaphe guttata, a common snake in the Southeast, for which information is scarce. Ten E. guttata were studied in East Tennessee using radio telemetry, and home range was calculated from five E. guttata from global positioning system (GPS) data. Mean home range was 5.07 ha and mean body temperature was 25.6 ± 3.5°C. Movement in E. guttata is linked to body and air temperature and to resource availability. Egg temperatures, which have never been observed in the wild, were 22.8 ± 0.3°C.
