Data are expressed as means ± SD from n = 5–7 individuals per group. In each parameter, there was a significant effect of acclimation temperature (P < 0.05) but not of genotype. WA, warm acclimated; MCA, moderately cold acclimated; UCP1, uncoupling protein 1; KO, knockout; RMR, resting metabolic rate; T_b, body temperature. ^a,bDifferences between mean values at 30°C and 5°C, respectively, are indicated by superscripted letters that differ.
