Abstract

Thermoregulation is a critical mechanism that allows reptiles to enhance physiological performances such as digestion, running, and embryo development. Gopherus polyphemus relies on thermoregulatory behavior to reach an optimum threshold for active behavior outside of their burrows. This study used internal and external temperature readings of tortoises found in the Abacoa Jupiter Greenway range VIA and compares them to behavior exhibited by the tortoise and environmental temperatures recorded. The results were compared to previous research conducted on gopher tortoises on sites of similar latitude and the results remained relatively consistent between study populations. A mean external carapace temperature of 31.8° C was determined for active behavior as well as a mean internal (cloacal) temperature of 32.3° C for active behavior. This internal temperature is slightly below previously recorded research, which states that active gopher tortoises have internal body temperatures ranging from 34-35° C.
