虽然海水运动是维持珊瑚礁健康状况的重要因素之一，但人们对海水湍流对珊瑚原生息肉生长的影响知之甚少。我们培养了无海水湍流和有海水湍流的鹿角珊瑚原生珊瑚，并研究了海水湍流如何影响珊瑚骨骼的物理特性。结果表明，海水湍流增加了骨骼碳酸盐的数量，直接影响珊瑚宿主的钙化。通过X射线显微计算机断层扫描进行的三维形态测量显示，海水湍流增加了息肉骨骼分支的厚度。在藻类共生体建立之前的早期生命阶段，骨骼分支的更大厚度和水平生长的增加可能会显着提高初级珊瑚虫的存活率。
Though seawater movement is among the important factors that maintain healthy conditions on coral reefs, little is known about the effects of seawater turbulence on the growth of coral primary polyps. We cultured aposymbiotic primary polyps ofAcropora digitiferawith and without seawater turbulence and investigated how seawater turbulence affected the physical characteristics of the polyp skeleton. Results showed that seawater turbulence increased the amount of skeletal carbonate and directly influenced calcification of coral hosts. Three-dimensional morphological measurements by X-ray micro-computed tomography revealed that seawater turbulence increased the thickness of the skeletal branches of polyps. Greater thickness of the skeletal branches and increased horizontal growth may significantly enhance survival of primary coral polyps during early life stages before the establishment of algal symbioses.
