Table 4: Strength and direction of gene flow for Acanthurus nigroris: (1) between the MHI ( individuals), NWHI ( individuals), and Johnston Atoll ( individuals), (2) among all remaining Pacific populations (), and (3) between Hawaiian and Pacific populations by pooling all sampled individuals (Hawaii, ; Pacific, ). Values are reported as the mean effective number of migrants per generation taken from ten independent runs.
