Temperature effects were analyzed using repeated-measures ANCOVA, with sex as a fixed factor and body mass as a covariate. Repeatability was assessed from residuals of univariate ANCOVA with sex and body mass, using a one-tailed test.

All mice (N=14 females and 18 males) were tested at each of three temperatures (25°C, 10°C, 3°C).
