Values are means of medians (±s.d.) 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). UETa,upper escape ambient temperature; LETa, lower escape ambient temperature; Ta, ambient temperature; HTbL and LTbL, high and low body temperature limits, respectively (limits of the central 68% range of the body temperature distribution); RTb,ambient temperature range (HTbL–LTbL); Tb, body temperature. Statistical analysis was not performed on the HTbL and LTbL to minimize type I error due to the intrinsic dependence between these variables and RTb
