珊瑚礁已成为最易受气候变化影响的生态系统之一。虽然气候变暖导致活珊瑚覆盖面丧失的情况在大的空间和时间尺度上都有很好的记录，但对鱼类的相关影响却没有。在此，我们响应最近一再发出的呼吁，即评估在全球气候变化背景下地方管理对养护珊瑚礁的重要性。这些信息很重要，因为珊瑚礁鱼类群落是地球上物种最密集的脊椎动物群落，为热带国家的人类社会提供重要的生态系统功能和生态系统服务。我们对1998年大规模漂白事件对珊瑚覆盖、珊瑚礁结构复杂性和与珊瑚礁相关的鱼类的影响进行了评估，涵盖了印度洋7个国家、66个地点和26个纬度。使用贝叶斯元分析，我们表明，珊瑚礁鱼类群落的大小结构，多样性和营养成分的变化，遵循珊瑚下降。虽然这些珊瑚礁生态系统在海洋尺度上的完整性已经丧失，但积极的是，这些影响在多个尺度上具有空间可变性，其影响和脆弱性受到地理而不是管理制度的影响。现有的禁捕海洋保护区仍然维持着较高的鱼类生物量，但它们对生态系统对大规模干扰的反应没有积极的影响。这表明，今后的养护和管理工作需要确定和保护区域避难所，应将其纳入现有的管理框架，并与提高全系统对气候变异和变化的复原力的政策相结合。
Coral reefs have emerged as one of the ecosystems most vulnerable to climate variation and change. While the contribution of a warming climate to the loss of live coral cover has been well documented across large spatial and temporal scales, the associated effects on fish have not. Here, we respond to recent and repeated calls to assess the importance of local management in conserving coral reefs in the context of global climate change. Such information is important, as coral reef fish assemblages are the most species dense vertebrate communities on earth, contributing critical ecosystem functions and providing crucial ecosystem services to human societies in tropical countries. Our assessment of the impacts of the 1998 mass bleaching event on coral cover, reef structural complexity, and reef associated fishes spans 7 countries, 66 sites and 26 degrees of latitude in the Indian Ocean. Using Bayesian meta-analysis we show that changes in the size structure, diversity and trophic composition of the reef fish community have followed coral declines. Although the ocean scale integrity of these coral reef ecosystems has been lost, it is positive to see the effects are spatially variable at multiple scales, with impacts and vulnerability affected by geography but not management regime. Existing no-take marine protected areas still support high biomass of fish, however they had no positive affect on the ecosystem response to large-scale disturbance. This suggests a need for future conservation and management efforts to identify and protect regional refugia, which should be integrated into existing management frameworks and combined with policies to improve system-wide resilience to climate variation and change.
