Within the few years following the publications of the first studies on reptilian thermoregulation (Mosauer, 1936; Attsatt, 1939; Cowles and Bogert, 1944; and Strelnidov, 1944) there has been an increasing number of investigations concerned with the mechanisms that underlie this phenomenon. Many studies have demonstrated that heliothermic lizards maintain a relatively constant body temperature during per- iods of diurnal and seasonal activity. Much of this regulation is dependent upon behavior. An extensive review of thermoregulation in both lizards and snakes has been compiled by St. Girons and St. Girona (1956).
