N = sample size per population; n = mean sample size over all loci; P = proportion of polymorphic loci; A = mean number of alleles per locus; Ar = mean number of alleles standardized to the smallest sample. H_e = unbiased expected heterozygosity standardized according to the (2N/2N-1)*H_e) formula; H_o = observed heterozygosity, Lat is the latitude (N) and Long is the longitude (W).
