Fig. 2. Mean differences between air temperature (Ta) and body
temperature (Tb) of six Gila monsters at five experimental
temperatures. Increasing Ta led to increasing suppression
of Tb (P<0.0001), and Tb
was consistently lower than Ta at higher temperatures.
Asterisks represent significant differences (P<0.01) between the
control and diaper trial values. Vertical and horizontal error bars represent
± 1 S.E.M. for temperature suppression
and chamber temperature, respectively.
