摘要: Genetic diversity and population structure of Ammodytes personatus in the Northwestern Pacific were investigated for 16 collections using eight highly variable microsatellite loci. Microsatellite analyses gave strong support for the presence of two distinct groups of genotypes. Pleistocene glaciations can cause significant geographical differentiation in A. personatus populations. However, microsatellite data cannot confirm completely reproductive isolation between north group and south group. About half of comparison values within the first and second cluster were significant after sequential Bonferroni corrections. Routine oceanic currents associated with strong wind condition may provide an excellent chance for connectivity of among populations within clusters. However, gene flow can be restricted by marine gyres due to complex geographical characteristic. (C) 2015 Elsevier Ltd. All rights reserved.
