In total, 52 climate variables were tested (Supplemental Table 3); the 12 variables with P < 0.001 (Mann-Whitney U test) are shown. Means ± se. M-W, Mann-Whitney U test; Mixed Model, mixed model with correction for kinship [*P < 0.05, ** P < 0.01, and ***P < 0.001; below the Bonferroni threshold (0.05/52 = 0.001)].
