| Outline of Final Research Achievements |
Because infestation on urban areas by Asiatic black bear (following bear) leads to a large amount capture, the grasp of the ratio of such bear is important for evaluating the population viability. In this study, we carried out the individual identification by using camera traps for bear population in Toyama prefecture, Japan. Our main purpose is to evaluate the influence that the present bear management gives to the population viability of the bear. In the poor hard mast production year, the bear frequently use urban area in fall. About the bear reproduction, the birthrate is high in the next year of bumper production and it is low in the next year of poor production. We estimated behavioral process by using a continuous-time spatial capture-recapture model based on the two-dimensional Ornstein-Uhlenbeck process. In poor production year, bear home-range size became large because gravitation to the home-range center is small but movement speed is slow.
