| Outline of Final Research Achievements |
Research was conducted to clarify 1) the effects of lianas and epiphytes on the distribution of soil invertebrates and the arboreal food-web structure, 2) dynamics of arboreal organic matter, and 3) litter decomposition on the aboveground part of the forests. Our results showed that (1) a large number of soil invertebrates inhabit the aboveground part of a conifer forest, and their fall is related to temperature and precipitation; (2) lianas affect invertebrate communities on tree trunks; (3) the presence of physical structures such as lianas reduce predation on tree trunks.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、森林生態系の地下部（林床）に生息する土壌動物が、地上部（林冠・樹幹）に移動し、地上部の機能に影響すること、そしてその移動にはつる植物が関連すること、を明らかにした。これらの成果は、森林生態系の2つのサブシステムの連関性と、その連関の触媒となる存在の重要性を示しており、森林生態系の機能的側面やそのメカニズムの解明に対して寄与する知見をもたらすものと言える。
