Abstract

Colonies are the basic geometric building blocks of coral reefs. However, the forming regulations of both colonies and reefs are still not understood adequately. Therefore, in this study, we reconstructed 25 samples using high-resolution micro-computed tomography to investigate coral growth patterns and parameters. Our skeleton and canal reconstructions revealed the characteristics of different coral species, and we further visualized the growth axes and growth rings to understand the coral growth directions. We drew a skeleton grayscale map and calculated the coral skeleton void ratios to ascertain the skeletal diversity, devising a method to quantify coral growth. On the basis of the three-dimensional (3D) reconstructions and growth parameters, we investigated the growth strategies of different coral species. This research increases the breadth of knowledge on how reef-building corals grow their colonies, providing information on reef-forming regulations. The data in this paper contain a large amount of coral growth information, which can be used in further research on reef-forming patterns under different conditions. The method used in this study can also be applied to animals with porous skeletons.

摘要

群体是珊瑚礁的基本几何构建单元。然而，群体和珊瑚礁的形成规律仍未得到充分理解。因此，在本研究中，我们使用高分辨率微型计算机断层扫描重建了25个样本，以研究珊瑚的生长模式和参数。我们的骨骼和管道重建揭示了不同珊瑚物种的特征，并且我们进一步可视化了生长轴和生长环以了解珊瑚的生长方向。我们绘制了骨骼灰度图并计算了珊瑚骨骼孔隙率以确定骨骼多样性，设计了一种量化珊瑚生长的方法。基于三维（3D）重建和生长参数，我们研究了不同珊瑚物种的生长策略。这项研究拓宽了关于造礁珊瑚如何生长其群体的知识广度，提供了有关珊瑚礁形成规律的信息。本文中的数据包含大量珊瑚生长信息，可用于进一步研究不同条件下的珊瑚礁形成模式。本研究中使用的方法也可应用于具有多孔骨骼的动物。
