  1. For each species, populations are ordered from North to South below the species-level estimates. HE: expected heterozygosity; AR: allelic richness; HR: haplotypic richness; MNbPwDiff: mean number of pairwise differences between pairs of individuals. *indicates FIS indices that were significantly > 0. All nDNA estimates include locus Aru1, except for A. scopulorum populations. CpDNA haplotypes are characterized as `specific’ to a species when they only occur in this species. Different letters as superscripts after species means indicate significantly different values.
