Summary of genetic variation across all locations at four sites.¹

1N is sample size, NA is number of alleles, AR is allelic richness, HE is expected heterozygosity, and Ho is observed heterozygosity. Bold numbers indicate values for entire populations when locations are pooled; they are NOT averages among locations, except in the following case: for allelic richness, the first bold number represents pooled locations, while the second bold number after the slash represents location averages. Starred (*) values for observed heterozygosity reflect significant heterozygote deficits at those locations.
