| Outline of Final Research Achievements |
To clarify arboreal food-webs and their ecosystem functioning on trees, we investigated community structure of terrestrial and aquatic invertebrates, habitat utilization by arboreal frogs, and litter decomposition in treeholes and on epiphytes. Our results showed that arboreal habitats varied with patch size, litter quantity, their height, presence of surrounding vegetation, and litter types, and that the inhabitants and their habitat utilization were affected by the characteristics of habitat patches. We also suggest that a part of terrestrial invertebrates moved from forest floor to arboreal habitats and played a role in litter decomposition on epiphytes.

| Academic Significance and Societal Importance of the Research Achievements |
森林内の異なるサブシステム（樹上と林床）間を移動する動物の群集構造、生息場所利用、機能的役割を明らかにした本研究の成果は、システム間（サブシステム間）のつながりが生態系内の生物多様性の維持および生態系機能に重要であることを示した。このことは、生態系を理解するうえでシステム間相互作用に着目することの必要性を提示しており、基礎的な生態学分野や生物種の保全のような保全生物学分野に対して寄与する知見をもたらすものと言える。
