Outline of Final Research Achievements |
This study aimed to clarify the factors causing spatial variation in ecosystem functioning and ecosystem services of eelgrass meadows in the Pacific Rim. We compared and analyzed the ecosystem functioning and services of eelgrass beds among the sites in both Japanese coast and the West coast of North America where some coastal foundation species had been transported from Japan with Japanese oyster seedlings. The analyses showed not non-native species but oyster farming itself caused the shift in functional structure from grazing-dominant to filter-feeding dominant and that the fish biomass was also more abundant in the seagrass bed with pacific oyster reef. It has been known that original pacific oyster reef is often established adjacent to eelgrass beds and has trophic-facilitative interactions with seagrass beds. Our result suggests a possibility that the original interaction between oyster and seagrass may appear also in the recipient eelgrass bed with oyster farming.
