Genetic patterns in peripheral marine populations of the fusilier fish <i>Caesio cuning</i> within the Kuroshio Current

Abstract

Despite the potential for homogenizing gene flow along the Kuroshio Current, peripheral populations in <i>C. cuning</i> conform to the predictions of the CCPM. While oceanography, habitat availability, and dispersal ability are all likely to shape the patterns found in <i>C. cuning</i> across this central-peripheral junction, the impacts of genetic drift and natural selection in increasing smaller peripheral populations appear to be probable influences on the lineage divergence found in the Ryukyu Islands.
