Median-joining haplotype network of CO1 sequences.
The median-joining network was constructed using 108 CO1 sequences and was visualized using POPART v1.7. Each circle represents a haplotype, and the size of a circle is proportional to the number of sequences assigned to that haplotype. The location from which the sequence was obtained is indicated by color in the legend. The number of hatch marks indicate the number of nucleotide differences that separate the haplotypes. A black dot represents an intermediate missing haplotype.
