| Research Abstract |
We examined the geographic distribution pattern of mitochondrial DNA sequence polymorphisms of salmonid fishes, Dolly Varden Salvelinus malma and white-spotted charr S. leucomaenis, over most of its range in the North Pacific rim, to assess how its spatial population genetic structure has been molded. The haplotypes from Dolly Varden were grouped into three main lineages, which correspond to western, central, and eastern regions in the North Pacific. Some diagnostic and genetically differentiated haplotypes were identified around the southerly populations (Honshu Island) of white-spotted charr.
