中光珊瑚生态系统可以作为造礁珊瑚在持续的气候变化中生存的避难所。珊瑚种类的分布在幼虫扩散期间发生变化。然而，不同深度的珊瑚在生命早期阶段的适应潜力尚不清楚。本研究调查了驯化潜力的四个shallowAcroporaspecies在不同的深度，通过移植的幼虫和早期的珊瑚虫定居在瓷砖5，10，20和40米的深度。然后，我们检查了生理参数，如大小，存活率，生长速度和形态特征。对A. tenuisandA. 40 m深度的有效性显著高于其他深度。与此相反，A.毛地黄和风信子在浅层表现出较高的存活率。形态学（即，珊瑚的大小）也在不同的深度。总的来说，浅珊瑚幼虫和青少年在深度表现出很大的可塑性。
Mesophotic coral ecosystems may serve as a refuge for reef-building corals to survive the ongoing climate change. Distribution of coral species changes during larval dispersal. However, the acclimation potential in the early life stages of corals at different depths is unknown. This study investigated the acclimation potential of four shallowAcroporaspecies at different depths via the transplantation of larvae and early polyps settled on tiles to 5, 10, 20, and 40 m depths. We then examined physiological parameters, such as size, survival, growth rate, and morphological characteristics. The survival and size of juveniles ofA. tenuisandA. validaat 40 m depth were significantly higher than those at other depths. In contrast,A. digitiferaandA.hyacinthusshowed higher survival rates at shallow depths. The morphology (i.e., size of the corallites) also varied among the depths. Collectively, the shallow coral larvae and juveniles displayed substantial plasticity at depth.
