| Outline of Final Research Achievements |
In this study 1. We conduct experimental studies using 6 different tropical reef building coral species and clear the intra-species response variation of corals to Ocean Acidification. Additionally, 2. We clear that the coral Acropora digitifera have a strong intra-species tolerance variation to the ocean acidification, and 3. The tolerance variation of A. digitifera was suggested to be related on the genetic expression of calcification related genes such as Ca-ATPase. From these results it is suggested that Ocean Acidification will cause both decrease on coral growth and change on coral community structure. Meanwhile, we clear for the first time that some coral species potentially are able to adapt in the future Ocean acidified environment.
