| Research Abstract |
The purpose of this research is to understand the mechanism on the dynamic micro ecosystem in coral. We found that 30oC is a threshold temperature for inducing bleaching and reducing photosynthesis by 50%. Moreover pathogenic bacteria can enhance and accelerate temperature mediated bleaching. Primary production in coral reef is higher than previously thought. New approaches using micro sensors are “coral holobiont”, which is composed of corals with zooxanthellae, and associated icrobes (bacteria, fungi, cyanobacteria among others). There is a semi-closed environment for the coral internal metabolism.
