Research Abstract |
We aimed to understand responses of coral-zooxanthella symbiotic system to combined stresses. Our major findings are; (1) algal symbionts become a burden for the host under stressful conditions, (2) symbiont type affects the stress response of coral juveniles, and (3) some coral and algal genes exhibit stress-specific changes in expression. Colonial morphology and host genotypes also affect stress susceptibility of corals. The cause of death of corals, changes in recruitment rate, and population dynamics of corals in Okinawa were analyzed.
