| Outline of Final Research Achievements |
Japanese macaques caused a rapid loss of deadwood volume, and furthermore, the fragmented deadwood was more likely to be trampled by Japanese deer in the western coastal forest in Yakushima Island, Japan. Japanese macaques broke white-rot wood in a late stage of decay in forests to feed on arthropods, and such wood was inhabited by arthropods such as larvae of beetles, cockroaches, and termites. The results of the present study suggest that medium and large mammals play an additional role in promoting deadwood decomposition especially in the late stage of decomposition.
