  1. 1Number of multilocus genotypes in each population;
  2. 2Mean allelic richness and standard deviation computed per locus and rarefied to the population with the lowest sample size (North America). In brackets, mean allelic richness computed for populations with more than 10 MLGs;
  3. 3Private alleles observed in each population;
  4. 4Shannon-Weiner diversity index;
  5. 5Simpson’s diversity index;
  6. 6Nei’s gene diversity (expected heterozygosity);
  7. 7Observed heterozygosity;
  8. 8Index of association for each population with P-value (in brackets) resulting from a one-sided permutation test;
  9. 9Standardized index of association for each population with P-value (in brackets) resulting from a one-sided permutation test
