| Outline of Final Research Achievements |
Reef building corals disperse to new environments through their planktonic larvae. During the larval stages corals acquire symbiotic algae (zooxanthellae) from the environment. The pupose of this study was to study the symbiont acuisition in a context of poleward shift in distribution range, as is currently observed with global warming. We examined how coral develop symbiosis with different algae when transplanted in regions with different water temperature and light conditions. The results obtained suggest that juvenile corals originating from Okinawa and reaching temperate area such as Kochi can survive at least until three months. However, although temperate and tropical native adults harbor the same symbiont types, the symbionts acquire are different between juveniles grown in their original location and transplants. This finding suggest that more than species specific preferences, juvenile corals acquire mainly available types present in the environment.
