Minimum spanning networks for COI haplotypes (circles) in (A) Mytilicola intestinalis and (B) M. orientalis. Branch length is proportional to the number of nucleotide differences (the shortest branches represent one nucleotide difference). The black dots on the branches represent missing haplotypes. Frequency of observation is proportional to circle area. Colors represent large scale differentiation between clusters of haplotypes and correspond with the pie charts in Fig. 4. Figure 2 was drawn in Adobe Illustrator based on the Arlequin output list of OTU differences.
