Outline of Final Research Achievements

To clarify the mechanisms of biodiversity in forest canopies, we focused on arboreal resource patches (dry and water-filled treeholes, dead wood, attached litter, etc.), and investigated invertebrate communities in the microhabitats.Our results showed that 1)community structures of invertebrates (spiders and springtails) were different between vertical layers of forests, that 2)size and shape of resource patches (treeholes) affect the detritus and water subsidies, resulting in changing the communities, and that 3) variety of resource size (diameter of dead wood) causes resource partitioning of wood-dwelling species, and thus contributes to species diversity.
