Widespread Dispersal of the Crown-of-Thorns Sea Star, Acanthaster planci, across the Hawaiian Archipelago and Johnston Atoll

Figure 2

Median joining haplotype network of Acanthaster planci samples from Johnston Atoll and the Hawaiian Archipelago. The network to the right includes the samples from 1982 and the network to the left does not. Each circle represents a unique haplotype connected by a line to those that differ by one or more base pairs. Those lines that represent >4 bp differences were labeled, but lines are not to scale. Nodes on the lines indicate missing haplotypes. Each haplotype is color coded by region and size of the pie chart is proportional to frequency. The smallest colored circles represent a singleton haplotype and the largest circle represents 20 individuals who share that haplotype.
