珊瑚疾病的爆发是加勒比海珊瑚礁面临的最大威胁之一，但导致珊瑚疾病的机制在很大程度上仍然未知。在这里，我们研究了已知基因型的鹿角珊瑚菌落上的白痘病的时空动态。我们采用贝叶斯方法，使用集成嵌套拉普拉斯近似算法，以检查哪些协变量影响了7年内白痘病的存在。我们发现，菌落大小，遗传易感性的珊瑚主机，和高水温是主要的测试变量，与白痘病的存在，对A。palmata殖民地我们的研究还表明，无论是距离以前患病的个人，也没有殖民地的位置，影响白痘病的动态。这些结果表明，白痘病最有可能是由于水温过高，选择性地损害了最古老的殖民地和最敏感的珊瑚基因型。
Outbreaks of coral diseases are one of the greatest threats to reef corals in the Caribbean, yet the mechanisms that lead to coral diseases are still largely unknown. Here we examined the spatial-temporal dynamics of white-pox disease on Acropora palmata coral colonies of known genotypes. We took a Bayesian approach, using Integrated Nested Laplace Approximation algorithms, to examine which covariates influenced the presence of white-pox disease over seven years. We showed that colony size, genetic susceptibility of the coral host, and high-water temperatures were the primary tested variables that were positively associated with the presence of white-pox disease on A. palmata colonies. Our study also showed that neither distance from previously diseased individuals, nor colony location, influenced the dynamics of white-pox disease. These results suggest that white-pox disease was most likely a consequence of anomalously high water temperatures that selectively compromised the oldest colonies and the most susceptible coral genotypes.
