Fatty acids and stable isotopes of coral tissue from sites with high and low internal wave action in the Andaman sea@en

In March 2018, specimens of the corals Pocillopora cf. verrucosa and Porites cf. lutea were collected via SCUBA diving (~15 m depth) from eastern shores with low internal wave forcing and western shores with high internal wave forcing at Ko Miang and Ko Racha in the Andaman Sea. Stable isotopes (carbon, nitrogen) and fatty acids of seperated coral host and Symbiodiniaceae fractions were analysed to infer whether internal wave forcing influences coral trophic mode (heterotrophy vs. autotrophy).2018年3月，研究人员通过水肺潜水（SCUBA diving，作业水深约15米），于安达曼海的科米昂岛（Ko Miang）与拉查岛（Ko Racha），分别在内波作用力较弱的东岸以及内波作用力较强的西岸海域，采集了疣状杯形珊瑚（Pocillopora cf. verrucosa）与浅灰滨珊瑚（Porites cf. lutea）的标本。随后对分离得到的珊瑚宿主与虫黄藻科（Symbiodiniaceae）组分的稳定同位素（碳、氮）及脂肪酸进行分析，以探究内波作用力是否会影响珊瑚的营养模式（异养与自养）。
