Abstract

Coral reefs house one-third of all marine species and are of high cultural and socioeconomic importance. However, coral reefs are under dire threat from climate change and other anthropogenic stressors. Climate change is causing coral bleaching, the breakdown of the symbiosis between the coral host and its algal symbionts, often resulting in coral mortality and the deterioration of these valuable ecosystems. While it is essential to counteract the root causes of climate change, it remains urgent to develop coral restoration and conservation methods that will buy time for coral reefs. The manipulation of the bacterial microbiome that is associated with corals has been suggested as one intervention to improve coral climate resilience. Early coral microbiome-manipulation studies, which are aimed at enhancing bleaching tolerance, have shown promising results, but the inoculated bacteria did generally not persist within the coral microbiome. Here, we highlight the importance of long-term incorporation of bacterial inocula into the microbiome of target corals, as repeated inoculations will be too costly and not feasible on large reef systems like the Great Barrier Reef. Therefore, coral microbiome-manipulation studies need to prioritise approaches that can provide sustained coral climate resilience.
推进珊瑚微生物组操作以建立长期气候适应性
珊瑚礁是所有海洋物种的三分之一,具有很高的文化和社会经济重要性。然而,珊瑚礁正受到气候变化和其他人为压力因素的严重威胁。气候变化正在造成珊瑚白化,破坏珊瑚宿主与其共生藻类之间的共生关系,往往导致珊瑚死亡和这些宝贵的生态系统恶化。虽然消除气候变化的根本原因至关重要,但制定珊瑚恢复和保护方法仍然紧迫,这将为珊瑚礁赢得时间。与珊瑚相关的细菌微生物群的操纵被认为是提高珊瑚气候适应能力的一种干预措施。早期的珊瑚微生物组操纵研究,旨在提高漂白耐受性,已经显示出有希望的结果,但接种的细菌通常不能在珊瑚微生物组中持续存在。在这里,我们强调长期将细菌接种剂纳入目标珊瑚的微生物组的重要性,因为重复接种将过于昂贵,并且在像大堡礁这样的大型珊瑚礁系统中不可行。因此,珊瑚微生物组操纵研究需要优先考虑能够提供持续珊瑚气候适应能力的方法。
