^A see Figure 1 for the designation of the gene pools; ^B Allelic richness; ^C Observed proportion of heterozygotes; ^D Within population gene diversity; ^E Overall gene diversity; ^F * indicates that the population differentiation index (F_ST) is significantly different from 0 as measured by an exact G test_;^G * indicates that R_ST is significantly superior to the F_ST (presence of a phylogeographic signal); ^H Locus 14H was excluded (high frequencies of null alleles) in all the analyses for this gene pool; ^I Not available due to missing data for one locus in at least one of the population.
