摘要:

文章以非虫黄藻共生型珊瑚Cladopsammia sp.为研究对象, 将对照组的海水设置为26℃恒温, 试验组从26℃升温至33℃, 以此探究海水升温对Cladopsammia sp.代谢和钙化生理的影响。结果显示: 在高温胁迫下, 虽然Cladopsammia sp.钙化相关酶(Ca2+-ATP酶和Mg2+-ATP酶)的活性出现了负响应, 但是珊瑚的呼吸速率、生长速率、组织中总蛋白和粗脂肪都没有显著改变(p>0.05)。比较历史文献结果和本研究结果表明: Cladopsammia sp.可能由于体内没有虫黄藻共生, 表现出了比大部分虫黄藻共生珊瑚更高的温度耐受能力。

Abstract:

To study the effects of ocean warming on the metabolism and calcification physiology of azooxanthellate coral - Cladopsammia sp., we set the seawater in controlling group at 26 ℃, and the temperature of experimental group was increased from 26 ℃ to 33 ℃. The results indicated that although the activity of calcification-related enzymes (Ca2+-ATPase and Mg2+-ATPase) of Cladopsammia sp. showed a negative response, the respiration rate, growth rate, total protein and crude lipid in tissues of this coral were not significantly altered under thermal stress (p > 0.05). The comparison between the data of previous studies and this study shows that Cladopsammia sp. exhibited higher temperature tolerance than most zooxanthellate corals, probably because it does not have Symbiodinium. At present, the research on the thermal stress of azooxanthellate corals is very limited. It is necessary to strengthen the research on the mechanism of tolerance of these corals, to help us predict more accurately the impact of future environmental changes on coral reef ecosystem in China.

Key words: ocean warming, azooxanthellate coral Cladopsammia sp., metabolism, calcification
