Genetic patterns in peripheral marine populations of the fusilier fish Caesio cuning within the Kuroshio Current.

ABSTRACT:

Aim

Mayr's central-peripheral population model (CCPM) describes the marked differences between central and peripheral populations in genetic diversity, gene flow, and census size. When isolation leads to genetic divergence, these peripheral populations have high evolutionary value and can influence biogeographic patterns. In tropical marine species with pelagic larvae, powerful western-boundary currents have great potential to shape the genetic characteristics of peripheral populations at latitudinal extremes. We tested for the genetic patterns expected by the CCPM in peripheral populations that are located within the Kuroshio Current for the Indo-Pacific reef fish, Caesio cuning.

Methods

We used a panel of 2,677 SNPs generated from restriction site-associated DNA (RA
