  1. Abbreviations: S, segregating sites; h, haplotypes; Hd, haplotype diversity; πsi, silent-site diversity from pairwise differences; θsi, silent-site diversity from the number of segregating sites.
  2. Diversity estimates were calculated for each country in both species, and for all African samples for C. elegans but not for C. briggsae due to the distinct geographical structuring between countries in this species. For C. elegans, there were a total of 17 strains—7 from South Africa, 9 from Kenya and 1 from Madagascar (LKC34). For C. briggsae, there were a total of 17 strains—9 from South Africa (including DF5100) and 8 from Kenya.
