  1. For each region, per-population means and overall values for the region are given. Npop: number of populations; Nind: number of individuals; Nh: number of haplotypes; Rh: haplotypic richness (number of haplotypes corrected for sampling size); Npr: number of private haplotypes; Rpr: number of private haplotypes corrected for sampling size; Hd: haplotype diversity; π: nucleotide diversity. Genetic diversity indices per population are detailed in Supplementary Table S1. Study localities are shown in Fig. 2a for C. robusta and Fig. 2b for C. intestinalis.
