Figure 2.

Median-Joining (MJ) and Reduced Median (RM) haplotype networks for both genes concatenated (ND1 and cyt b).A) Including all individuals analyzed in this study. Haplotypes found in individuals classified morphologically as A. fallax are represented in purple, while haplotypes found in individuals classified morphologically as A. alosa are colored in dark red. Shared haplotypes are represented by pie charts with the proportions reflecting the relative frequency of those haplotypes in A. alosa (dark red) and A. fallax (purple). The number (22) shown between the two main lineages (A. alosa and A. fallax) represents the number of substitutions. B) Haplotypes found in the 29 populations of A. fallax analyzed, excluding putative introgressed individuals; C) Haplotypes found in the nine populations of A. alosa analyzed, excluding putative introgressed individuals. In figures B and C, each clade is represented by different colors to facilitate the comparison with Figures 1 and 3. The area of each circle is proportional to the haplotype frequency. Each black dot represents a missing haplotype. Haplotype and clade nomenclatures correspond to those used in Figure 2 and Tables 4 and 5.
