Figure 1: Scaled maps indicating the collection sites and sample sizes for Acanthurus nigroris in the Pacific Ocean. Locations marked with an asterisk were omitted from most population genetic analyses owing to low sample sizes (i.e., in all cases) but were included when all (or only “Pacific”) populations were pooled together, as well as in subsequent statistical parsimony networks.

Note that the boundaries of the Papahānaumokuākea Marine National Monument include only the Northwestern Hawaiian Islands (Photo credit: Jack Randall).
