本研究旨在探讨在共生体光合作用和珊瑚钙化过程中，珊瑚的光合效率和恢复过程是否受到二氧化碳驱动的海洋酸化的影响。我们研究了在调节后的海水中，从300微大气压（工业化前）到800微大气压（不久的将来）的5种二氧化碳分压（pCO₂）水平以及强光和弱光强度对一种分枝珊瑚——尖枝列孔珊瑚（Stylophora pistillata）的最大光合效率和钙化的影响，因为该物种经常用于养殖实验，以研究酸化海水对珊瑚钙化和光合藻类的影响。我们发现，在不同光照条件下的光合效率和恢复模式在不同的pCO₂处理之间没有差异。此外，在弱光或强光条件下，尖枝列孔珊瑚的钙化不受酸化海水的影响。我们的研究结果表明，尖枝列孔珊瑚的光合效率和钙化对海洋酸度的变化不敏感。
The aim of this study was to investigate whether coral photosynthetic efficiencies and recovery processes are affected by CO2-driven ocean acidification in symbiont photosynthesis and coral calcification. We investigated the effects of five CO2 partial pressure (pCO2) levels in adjusted seawater ranging from 300 μatm (pre-industrial) to 800 μatm (near-future) and strong and weak light intensity on maximum photosynthetic efficiency and calcification of a branching coral, Stylophora pistillata, as this species has often been used in rearing experiments to investigate the effects of acidified seawater on calcification and photosynthetic algae of corals. We found that, the photosynthetic efficiencies and recovery patterns under different light conditions did not differ among pCO2 treatments. Furthermore, calcification of S. pistillata was not affected by acidified seawater under weak or strong light conditions. Our results indicate that the photosynthetic efficiency and calcification of S. pistillata are insensitive to changes in ocean acidity.
