Lizards in the slow lane: Thermal biology of chameleons

摘要

1. Field body temperatures (T-b's) of Chamaeleo chamaeleon in southwestern Spain averaged 28 degrees C in October and 30 degrees C in June. Slopes of regressions of T-b on T-a (ambient temperature at perch height) indicated that individuals were able to maintain a preferred body temperature of about 30 degrees C in June but not in October.2. Review of data from the literature indicated that chameleons in general have field body temperatures and selected body temperatures (means 30 and 31 degrees C, respectively) that are low relative to those of most other diurnal lizards.
