| Research Abstract |
The genetic population structure and phylogeography of freshwater fishes inhabiting rivers in eastern Eurasia were analyzed by mitochondrial DNA sequence data or mictosatellite DNA data. As the results, 1) several criptic species were found in the genus Lethenteron, Carassius, Pungitius, Cottus and Barbatula toni, indicating that the species richness of freshwater fishes in this region is higher than that of the hitherto view, and 2) in the Siberian region, deep lineage divergence was found in Barbatula toni, Cottus poecilopus and C.sibiricus, whereas shallow divergence was detected in Lethenteron species, Salvelinus leucomaenis and Pungitius species, suggesting that the ichthyofauna was formed multi-temporally.
