Description
| - Ectothermal vertebrates reg?ulate their body temperature within definite limits to maintain physiological processes at their optimal levels. Among others, food pro?cessing and absorption are strongly tempera?ture-dependent. Deficiency of adequate tem?peratures limits ectotherms in growth and maintenance. On the other hand, thermo?regulatory behavior is costly and should be constrained by many factors. Using artificial thermal gradients (26-44oC), we measured temperature preferences of 10 spiny-tailed agamas (Uromastyx acanthinura) in controlled indoor experiment. Each lizard could choose place in the terrarium before and after feed?ing. Then, temperature preferences during pre-feeding and post-feeding periods were compared. We found significant increase of preferred temperature after feeding. Detailed view revealed that there is consistent influ-ence of body size: bigger lizards maintained higher temperature during the whole experi-ment. We hypothesize that bigger potential predation risk on smaller lizards due to their size would force them to choose less optimal conditions
