Fig. 3

Median-joining haplotype network illustrating the relationships among 36 haplotypes from 133 individuals of E. canicularis based on Cytb. Circle size is proportional to haplotype frequency; branch length is not proportional to the number of mutations. Numbers on the branches represent mutations between haplotypes. HGI, HGII, HGIII and HGIV correspond to haplogroups I, II, III, and IV, respectively
