Demographic history and population structure of blackfin flounder (Glyptocephalus stelleri) in Japan revealed by mitochondrial control region sequences.
The demographic history and population genetic structure of the blackfin flounder (Glyptocephalus stelleri) along coastal regions of Japan were investigated. Genetic variation in DNA sequences was examined from the first hypervariable region of the mitochondrial DNA control region. A high level of haplotypic diversity (h = 0.99 +/- 0.004) was detected, indicating a high level of intrapopulation genetic diversity. The starburst structure of the minimum spanning tree suggested a very recent origin for most haplotypes. The demographic history of G. stelleri was examined using neutrality tests and mismatch distribution analysis, which also indicated a Pleistocene population expansion at about 124,100-413,400 years ago. Hierarchical molecular variance analysis and conventional population Fst comparisons revealed no significant genetic differentiation throughout the range examined.
