Polyp-canal reconstruction reveals evolution towards complexity in corals (Dataset Part 48)

There are 17 files in this dataset. This is the 48th part of this dataset. The <em>A. millepora</em>, <em>A. muricata</em>,<em> C. vaughani</em>,<em> M. capricornis</em>, <em>M. foliosa</em>,<em> P. damicornis</em>, <em>P. meandrina</em>,<em> P. verrucosa</em>, and<em> S. pistillata</em> samples were collected from the Xisha Islands (2018); the <em>A. digitifera</em>, <em>F. speciosa </em>(2008), and<em> M. turgescens</em> (2017) samples were collected from the Nansha Islands; the <em>P. lutea</em> samples were collected from the Weizhou Islands (2017); the <em>G. fascicularis</em>, and<em> M. stellata </em>samples were collected from the Gaven Reef (2017); the <em>A. myriophthalma</em> samples were collected from the Reed Tablemount (2017); the <em>P. sinensis</em> samples were collected from the Subi Reef (2017). All samples, which occurred in large arborescent colonies forming thickets, were found in tropical shallow reefs of the marine neritic zone, from depths of about 5 to 10 m. The daily mean temperature was between 23.2 and 29.2°C. The coral samples were kept whole and housed in our laboratory coral tank, where all conditions were simulated to reflect those of their habitat in the South China Sea. These samples were kept in the tank for about one to three months before HRCT analysis.

本数据集共包含17个文件，此为该数据集的第48个分卷。本次涉及的珊瑚样本按采样海域与时间划分如下：采自西沙群岛（2018年）的样本包括<em>A. millepora</em>、<em>A. muricata</em>、<em>C. vaughani</em>、<em>M. capricornis</em>、<em>M. foliosa</em>、<em>P. damicornis</em>、<em>P. meandrina</em>、<em>P. verrucosa</em>及<em>S. pistillata</em>；采自南沙群岛的样本包括<em>A. digitifera</em>（2008年）、<em>F. speciosa</em>（2008年）与<em>M. turgescens</em>（2017年）；采自涠洲岛的<em>P. lutea</em>样本采集于2017年；采自加文礁的<em>G. fascicularis</em>与<em>M. stellata</em>样本采集于2017年；采自雷迪海山的<em>A. myriophthalma</em>样本采集于2017年；采自渚碧礁的<em>P. sinensis</em>样本采集于2017年。所有样本均为形成茂密灌丛的大型树状群落，发现于海洋浅海地带的热带浅礁中，采样深度约为5至10米，该区域日平均水温介于23.2℃至29.2℃之间。所有珊瑚样本均保持完整形态，存放于本实验室的珊瑚饲养缸内，缸内环境参数均模拟了其在南海的原生栖息环境。样本在饲养缸中暂养约1至3个月后，开展了高分辨率计算机断层扫描（High Resolution Computed Tomography，HRCT）分析。
