| Research Abstract |
It was suggested that haplotypes of Asian black bear diverged into three clusters after the bears came into Japan from Asian continent, and then genetic structure was locally produced. Even though such genetic structures were temporally changed due to the mass intrusion, they recovered quickly after the mass intrusion. From these results, local genetic structures were proposed to apply for management units. The bear captured in 1987 in Kyushu was revealed to be, in origin, from Honshu. The possibility of the extinction in Kyushu increased because no bear has been captured over 50 years.
