The preferred body temperature was determined for several groups of Sceloporus occidentalis previously acclimated to several constant temperature levels. Acclimation to a high temperature (35°C) resulted in the selection of a lowered mean preferred body temperature, whereas acclimation to lower temperatures (12°C and 25°C) produced no change in the preferred body temperature.
