| Outline of Final Research Achievements |
Due to growing anthropogenic impacts on hydrothermal vents, understanding on community structuring and maintaining mechanisms through larval recruitment is crucial. In this study, we aimed to quantify the recruitment variability of benthos at the hydrothermal vents in the Okinawa Trough, using artificial colonization plates. We set the plates at six different vents and retrieved them from two vents. Animal composition and abundance on the plates were different between vents, among sites within a vent, and between timings of recovery of the plates. The variability found in the recruitment might be influenced by reproductive and early-life history characteristics.
