Outline of Final Research Achievements

Ctenactis echinata, as the rare case of "individual" scleractinian　coral species,　has　been　selected to　explore　the potential margin among thermal-stress responses within a population. The greater thermal sensitivities among sexually maturating individuals suggested the trade-off between maintainance and sexual reproduction in this species while stable tolerance were found among larger (older) individuals. In addition, expreiments focused on various life stages of Acropora digitifera such as; planktonic larvae, primarly polyps and mature colonies by cold-water stresses had been conducted. According to the results, niether planktonic larvae and mature colonies were not critically affected by cold stress however, primary polyps' calcification as well as budding rates were significantly suppressed. These results strongly suggest this species ability to survive under marginal region (temperate watar)envrionments is limited by the initial growth suppression.
