Current climate warming and associated stressors are thought to be especially hazardous for tropical coral reef ecosystems. We propose a project to study the response of reef corals to Pleistocene interglacial warming in terms of biogeographic shifts and community changes focusing on the Last Interglacial (LIG). Modern coral distributions serve as a benchmark against which the LIG distributions are tested taking taphonomic biases and sampling issues into account. Our study combines field-based research on selected equatorial reef terraces (Indonesia, Philippines, Kenya) with analyses of global coral occurrence data. The hypotheses to be tested are that (1) the latitudinal diversity gradient (LDG) of reef corals is dynamic and governed by climatically induced range shifts; (2) the modern unimodal LDG of reef corals changed to a bimodal pattern during the LIG; (3) latitudinal shifts of reef corals with warming were variable and linked to ecological traits and, (4) climate warming led to changes in community structure.

目前的气候变暖和相关的压力被认为对热带珊瑚礁生态系统特别危险。我们提出了一个项目来研究珊瑚礁的反应更新世间冰期变暖的地理变化和社区的变化集中在末次间冰期（LIG）。现代珊瑚分布作为一个基准，对LIG分布进行测试，考虑到埋藏偏差和采样问题。我们的研究将对选定的赤道礁阶地（印度尼西亚、菲律宾、肯尼亚）的实地研究与全球珊瑚发生数据的分析相结合。待检验的假设是：（1）珊瑚的纬度多样性梯度（LDG）是动态的，并受气候引起的范围转移;（2）现代单峰的珊瑚LDG改变为双峰模式的珊瑚在LIG;（3）珊瑚的纬度转移与变暖是可变的，并与生态特征，（4）气候变暖导致的群落结构的变化。
