First row indicates collection sites and location (island or mainland), molecular form in square brackets [M or S] and sample size in parenthesis; R_s: Allele richness; H_e: Nei's unbiased estimate of expected heterozygosity. All loci/samples: mean values over loci or populations; In bold: significant heterozygote deficits according to exact tests against Hardy-Weinberg proportions after corrections for multiple testing by the sequential Bonferroni procedure. N = 24: estimates made with a sample size of 24 individuals for all localities.
