n, number of samples; NA, mean number of alleles; HO, mean observed heterozygosity; HE, mean unbiased expected heterozygosity; AR, mean allelic richness (based on the minimum sample size of 46 across populations and loci); NH, number of haplotypes; h, haplotype diversity; HR, haplotype richness (based on the minimum sample size across populations). Standard deviations are in parentheses.
