Outline of Final Research Achievements

The purposes of the present study are to evaluate genetic variation of the endangered Hokkaido population of the Blakiston’s fish owl, and to establish the preservation system of genetic resources on this owl. The population genetic studies on the fish owls were performed using genetic markers including mitochondrial DNA, microsatellites and major histocompatibility complex (MHC) genes. The results of these genes commonly showed the genetic differentiations among the regionally isolated populations, low genetic diversity and rapid changes within each regional population probably due to genetic drift and inbreeding after bottleneck. In addition, the preservation system for genetic resources including new samples has been established with usable genetic information obtained in the present study.
