Figure 3
Unrooted p-distance neighbor-nets for C. elegans (a) and C. briggsae (b) based on concatenated multilocus haplotypes. C. elegans haplotype designations are as shown in Figure 2a; African haplotypes are designated by Greek letters; subscripts indicate the number of strains per haplotype and the country of origin (Aus, Australia; Can, Canada; Fra, France; Ger, Germany; Ken, Kenya; SAf, South Africa; Sco, Scotland). C. briggsae clades are labeled following the latitudinal clades with the symbols in parentheses corresponding to those used to represent the strains in Figure 1. Bootstrap values ⩾70% of 1000 replicates are shown next to the branches. Neighbor-joining trees are shown in Supplementary Figure S1.
