异常高的水温可能会增加病原体的丰度或毒性，或增加宿主的易感性，从而增加珊瑚疾病爆发的可能性。本研究测试的妥协主机的假设，并记录疾病和温度之间的关系，通过每月监测鹿角珊瑚殖民地从2004年5月至2006年12月，在Hawksnest湾，圣约翰，美属维尔京群岛（USVI）。疾病患病率和患病率的变化率分别与水温和水温变化率呈线性正相关，但仅在2005年温度长期升高期间。在2005年，漂白和未漂白的珊瑚群落都显示出疾病流行率与温度之间的正相关关系，但仅漂白珊瑚的疾病相关死亡率的平均面积增加，表明宿主易感性而不是温度本身影响了A.掌形的
Anomalously high water temperatures may enhance the likelihood of coral disease outbreaks by increasing the abundance or virulence of pathogens, or by increasing host susceptibility. This study tested the compromised-host hypothesis, and documented the relationship between disease and temperature, through monthly monitoring of Acropora palmata colonies from May 2004 to December 2006, in Hawksnest Bay, St John, US Virgin Islands (USVI). Disease prevalence and the rate of change in prevalence showed a positive linear relationship with water temperature and rate of change in water temperature, respectively, but only in 2005 during prolonged periods of elevated temperature. Both bleached and unbleached colonies showed a positive relationship between disease prevalence and temperature in 2005, but the average area of disease-associated mortality increased only for bleached corals, indicating host susceptibility, rather than temperature per se, influenced disease severity on A. palmata.
