Research Abstract	I investigated effects of environmental changes associated with secondary forest succession on dispersal patterns for fagaceous trees, which are important component species in a warm-temperate forest in western Japan. Even in a fragmented urban forest, the importance of biological interactions, such as interactions among insects, wood mice and acorns, was suggested for the initial establishment of fagaceous trees. For Castanopsis cuspidata, which is a shade-tolerant climax species, changes in chaching behavior of a wood mouse (Apodemus speciosus) associated with forest succession would significantly affect their dispersal pattern.
