- Abstract
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.
