N = number of individuals analysed; P = proportion of variable loci; number of private alleles (Priv.); NAR = mean allelic richness corrected for uneven sample size; NPAR = mean private allelic richness corrected for uneven sample size; HO = observed heterozygosity for polymorphic loci; π = nucleotide diversity. Standard errors (SE) for NAR, NPAR, HO, and π are indicated in parentheses.
