Multiple matrix regression with randomization (MMRR) for genetic differentiation at neutral loci [F _ST/(1 − F _ST)] in relation with geographical (log10 transformed) and environmental distances between each pair of Iberian populations. Environmental distances (PC1, PC2, and PC3) were estimated from a principal component analysis (PCA) on the 19 bioclimatic variables from the worldclim dataset. β: regression coefficient; t: t‐statistic; r ²: coefficient of determination; p: one‐tailed significance level

Geographic distance (log10)	−.666	−2.948	.049	.980

Environmental PC2	−.080	−1.619	.015	.863
