| Research Abstract |
Population genomic analyses were conducted using the anadromous fish Leucopsarion petersii as a model system to detect adaptive divergence among populations within a single species in marine environments. Genome scan using many microsatellites and candidate gene markers revealed that there were genomic signatures of positive selection in the Japan Sea lineage of this species. Thus, it is strongly suggested that adaptive divergence have occurred between the Japan Sea and Pacific Ocean lineages of this species.
