| Outline of Final Research Achievements |
Large mammals, specifically Asiatic black bear, dispersed no less than 10% of seeds they fed over 2 km from their seed sources. Stump-tailed macaque also showed long-distance dispersal of seeds. In contrast, birds dispersed seeds mostly within 300 m from their seed sources. In addition, Black bear was proved to transport seeds they fed toward sites of higher elevation. On the other hand, spatial genetic structure of Prunus species was not affected by presence/absence of large mammals, suggesting that the long-distance dispersal of seeds by them had a limited effect on genetic structure of local tree populations.
