  1. Abbreviations: AR, allelic richness; DTM, minimum distance of the population’s island to the mainland; isolation, time since island isolation in years before present; FIS, within-population inbreeding coefficient; HE, expected heterozygosity; HO, observed heterozygosity; NA, mean number of alleles across loci.
  2. aFor location, see Figure 1.
  3. bAsterisk marks significant departure (P<0.05) from Hardy–Weinberg equilibrium following sequential Bonferroni correction.
