Here, we examined the coral bleaching responses during the 2016 thermal stress event and post-bleaching changes in coral communities in the heavily disturbed reefs of the Bolinao-Anda Reef Complex (BARC), northwestern Philippines. Less than 25% of colonies bleached, with 77% attributed to five genera (Dipsastrea, Porites, Fungia, Seriatopora, and Montipora). Coral bleaching prevalence was associated with site location, coral composition, and coral abundance, suggesting that small-scale variation (<20 km) in coral communities (taxa and density) influences spatial variation in coral bleaching prevalence. There was no noticeable change in coral composition and cover two years after the bleaching event as exposure to chronic disturbance likely selected for the dominance of stress tolerant coral taxa and communities. Results show that the 2016 thermal stress event caused coral bleaching but with low prevalence at the BARC, which suggests that disturbed reefs may provide spatial refuge to coral communities from thermal stress.
在这里，我们研究了 2016 年热应激事件期间珊瑚白化的反应以及菲律宾西北部博利瑙-安达珊瑚礁复合体（BARC）受严重干扰的珊瑚礁的珊瑚群落的白化后变化。不到 25%的珊瑚白化，其中 77%归因于五个属（Dipsastrea、Porites、Fungia、Seriatopora 和 Montipora）。珊瑚白化的流行与地点位置、珊瑚组成和珊瑚丰度有关，这表明珊瑚群落（分类和密度）的小尺度变化（<20 公里）会影响珊瑚白化流行的空间变化。在白化事件发生两年后，珊瑚组成和覆盖率没有明显变化，因为长期的干扰可能选择了对压力耐受珊瑚类群和群落具有优势的物种。研究结果表明，2016 年热应激事件导致了珊瑚白化，但在 BARC 白化的流行率较低，这表明受干扰的珊瑚礁可能为珊瑚群落提供了免受热应激的空间避难所。
