Summary statistics for genetic variability within sample sites.

HS is the estimated average gene diversity [28]; a is the average number of alleles per locus, and Ar is the average allele richness ±1X standard deviation. FIS refer to average deviations from Hardy-Weinberg genotype proportions, with number of loci deviating in either direction given. P-values refer to the overall two sided test over all loci (Fisher’s summation procedure over nine single-locus tests), and locus names identify the tests that came out significant (no adjustments made for multiple tests). Bold values of FIS denote significant values in either direction.
