E « n=10. _i—i—i—1_ 18 h 24 h 6h 12h 18 h Time Figure 5. Mean selected body temperature pattern of Diplometopon zarudnyi in the thermal gradient during 24 hours. Numbers at each point indicate the SEM. The body temperature for active D. zarudnyi are higher in the field than in the laboratory because the animals were deprived of food during the experiment, and also may be the result of confinement to a limited space in the gradient. Van Berkum (1980) demon- strated that the SBT is lower in lizards with decreased food consumption. It is recommended to measure metabolism during the post absorptive state of diges- tion, so as to minimize any contribution of specific dynamic action (Eckert and Randall, 1983). As D. zarudnyi is fossorial, the low mean selected temperature (26°C) could extend activity and stabilize body metabolism in the sub-surface habitat. The present results supplement the previous published reports of lower temperature selection in amphisbae- nians. Avery (1982) noted that many fossorial snakes, amphisbaenians, sea snakes, fresh water and marine turtles, appear not to thermoregulate and that many select low temperatures. Evidence of thermoregula- tion in Amphisbaena mertensi was reported by Abe (1984); mean field body temperature and preferred temperature in the gradient was °C and °C respectively. Also, Martin et. al. (1990) reported marked field thermoregulation in Blanus cinereus and it selected low field body temperatures. Gatten and McClung (1981) reported the low mean body temper- ature for Trogonophis weigmanni in a range of °C to °C. A field study of Bipes biporus demon- strated that this worm lizard can thermoregulate if necessary, by vertical and horizontal changes in sub- strate positioning (Papenfuss, 1982). More rec
