Results were estimated as Pearson product-moment correlations between ANOVA residuals controlling only for site of birth and/or acclimation altitude (raw values), or residuals including mass as an additional covariate(mass-corrected values). Statistically significant results according to a one-tailed hypothesis are shown in bold
