Coral beaching due to increasing sea surface temperature causes a decline of global reef ecosystems. Turbidity and sedimentation are localized threats that may contribute to and exacerbate the impacts of coral bleaching. Some reports show that there are coral communities thriving in turbid conditions are resilient to bleaching-related mortality events. In the Philippines, information on the effects of turbidity and elevated levels of light attenuation on bleaching in coral assemblages is generally lacking. This study describes the response to coral bleaching of a turbid reef in Buluan Island Marine Sanctuary (BIMS), southern Philippines. Coral cover and diversity showed no changes after the bleaching event. Coral community composition and abundance in some genera were affected but the majority showed either no significant change or recovery to pre-bleaching state even with high bleaching index values. The dominance and presence of bleaching-susceptible genera even after the 2016 global bleaching event suggest that turbidity experienced in BIMS might have reduced the impact of intense irradiance on the reef. Findings from this study indicate the potential existence of turbid resilient reefs across the Philippines and recommend that they be immediately identified and protected.

由于海面温度升高，珊瑚滩化导致全球珊瑚礁生态系统下降。浊度和沉积物是局部威胁，可能会加剧并加剧珊瑚褪色的影响。一些报告显示，在浑浊的条件下兴旺的珊瑚群落对与漂白相关的死亡事件具有抵抗力。在菲律宾，通常缺乏有关浊度和增加的光衰减水平对珊瑚组合体漂白的影响的信息。这项研究描述了菲律宾南部布卢安岛海洋保护区（BIMS）对混浊礁石的珊瑚褪色的响应。漂白事件发生后，珊瑚的覆盖度和多样性没有变化。某些属的珊瑚群落组成和丰度受到影响，但即使漂白指数值很高，大多数人也没有显示出明显的变化或恢复到漂白前的状态。即使在2016年全球漂白事件发生后，漂白易感属的优势地位和存在也表明BIMS所经历的浊度可能已经降低了强烈辐照对珊瑚礁的影响。这项研究的结果表明，整个菲律宾可能存在浑浊的弹性礁石，建议立即对其进行识别和保护。
