Abstract
Delineating population genetic structure and gene flow is a critical for identifying evolutionary processes and effective conservation. In this study, we examined the genetic structure of masu salmon (Oncorhynchus masou) populations within the Atsuta River, Hokkaido, Japan. In addition, to infer whether dispersers contribute to next generation’s gene pool, a comparison between the genetic structure of juvenile and adult masu salmon was conducted. Significant genetic differentiation and isolation by distance were observed among populations of both juveniles and adults. The degree of genetic differentiation was larger among the juvenile samples, especially among geographically distant samples, than among the adults. These results suggest that a number of relatively stable discrete populations are maintained in the river and that the reproductive success of dispersers to distant tributaries was relatively low among distant tributaries.
