  1. N number of unique individuals genotyped per sampling region, Na number of alleles, Ne mean number of effective alleles, Ho observed heterozygosity, He expected heterozygosity, H Shannon-Weiner diversity index, Ia index of association, rbarD standardized index of association, Fis inbreeding coefficient, with 95% confidence interval (CI).
  2. Asterisks indicate significant p values at the 0.001 threshold. The “Total” row contains the sum of N, total Na, and total H and the mean for the other indices
