Fig. 3. Coefficients of variation of upper and lower (A) ambient (UETa
and LETa, respectively) and (B) body (UETb and
LETb, respectively) escape temperatures of bearded dragons during
exposure to different oxygen concentrations. Values are means of 12 lizards
during a 7.5 h period. *Significant differences relative to 21%
oxygen, with the Holm–Sidak post-hoc test
(P<0.05).
