Populations were used as random effects. We use the size of island (log-transformed) and the distance from the continent (log-transformed) as fixed effects. P-values < 0.05 are in bold

Ar microsatellite allele richness, H_o observed heterozygosity, H_e expected heterozygosity, MHC_AR MHC allelic richness, NaI average number of MHC alleles per individual, π average MHC nucleotide diversity, D average MHC diversity between amino-acid variants
