珊瑚白色鼠疫(WP)疾病的暴发已导致加勒比海造礁珊瑚的区域显著减少。由于流行病学数据的可得性更高，研究主要集中在浅海珊瑚礁(<；30米)。然而，在美属维尔京群岛，与浅层珊瑚礁相比，中上层(30-40米)珊瑚礁的WP病患病率似乎更高，并可能在环境干扰后抑制珊瑚的恢复。这项研究的目的是调查环境驱动因素与美属维尔京群岛浅海和中游珊瑚礁WP流行的时空模式的关系。我们使用水滴相机方法记录了2012至2015年间圣托马斯南陆架13个珊瑚礁地点(5个浅水礁，3个中深礁和5个中上层珊瑚礁)的WP流行情况。采用广义线性混合效应模型进行贝叶斯推断，研究环境因素对疾病流行的影响。我们发现，在雨季开始(6月)，当水的浊度和温度水平较高，而氧气和盐度水平较低时，WP有增加的趋势。中层生物礁的疾病患病率高于浅层或中深层生物礁，这可能是由于珊瑚(宿主)的可用性较高，以及可能的可湿性肺炎发生的温度阈值，允许疾病在中层生物礁上部长期持续(全年)。这是第一次在几个珊瑚礁地点和深处实施投放相机方法来调查珊瑚疾病的研究。该方法可用于其他快速组织损失病的调查，如新出现的石珊瑚组织损失病(SCTLD)。
Outbreaks of coral white plague (WP) disease have caused significant regional declines of reef‐building Caribbean corals. Due to a greater availability of epidemiological data, studies have primarily focused on shallow coral reefs (< 30 m). In the U.S. Virgin Islands, however, WP disease prevalence appears to be higher on upper mesophotic (30–40 m) coral reefs when compared with shallow reefs and may be inhibiting coral recovery after environmental disturbances. The aim of this study was to investigate the relationship of environmental drivers with spatio‐temporal patterns of WP prevalence across shallow and mesophotic coral reefs in the U.S. Virgin Islands. We recorded WP prevalence at 13 reef sites (five shallow, three mid‐depth and five upper‐mesophotic reefs) across the south shelf of St. Thomas approximately monthly between 2012 and 2015 using a drop camera method. The influence of environmental factors on disease prevalence was investigated using Bayesian inference with generalized linear mixed‐effect models. We found that WP tended to increase during the beginning of the rainy season (June), and when levels of water turbidity and temperature were higher, and levels of oxygen and salinity lower. The disease prevalence was higher on mesophotic than on shallow or mid‐depth reefs, probably due to higher availability of corals (host), and a possible temperature threshold for WP occurrence that allows long‐term persistence (year‐round) of the disease on upper‐mesophotic reefs. This is the first study to implement the drop camera method to survey a coral disease over several reef sites and depths. This method can be applied on surveys of other rapid tissue loss diseases, such as the newly emergent stony‐coral‐tissue‐loss‐disease (SCTLD).
