微生物通过介导营养物质转化、与大型生物的相互作用以及提供支持各种珊瑚礁分类群招募的化学线索，对珊瑚礁生态系统的健康和恢复能力做出了重大贡献。然而，环境变化经常导致微生物群落的组成和功能变化，这可能对微生物介导的过程产生流动后果。这些微生物的变化可能影响特定宿主生物的健康，并可能对整个珊瑚生态系统的功能产生影响。因此，评估珊瑚礁微生物群落的变化应提供生态系统影响的早期指标，并将支持开发诊断工具，帮助预测不同环境状态下珊瑚礁健康状况的变化。为应对全球珊瑚礁健康状况的下降，最近加强了监测、管理和积极恢复工作，并使其多样化。在这里，我们建议定期监测珊瑚礁微生物可以为识别生态系统健康状况下降提供一个快速和敏感的平台，可以补充现有的管理框架。通过总结对珊瑚礁最常见的威胁，特别关注大堡礁，并详细阐述微生物在珊瑚礁健康和生态系统稳定中的作用，我们强调了微生物在珊瑚礁管理计划中的诊断适用性。实现这一目标的基础是为澳大利亚的珊瑚礁建立微生物基线。
Microorganisms make a significant contribution to reef ecosystem health and resilience via their critical role in mediating nutrient transformations, their interactions with macro-organisms and their provision of chemical cues that underpin the recruitment of diverse reef taxa. However, environmental changes often cause compositional and functional shifts in microbial communities that can have flow-on consequences for microbial-mediated processes. These microbial alterations may impact the health of specific host organisms and can have repercussions for the functioning of entire coral ecosystems. Assessing changes in reef microbial communities should therefore provide an early indicator of ecosystem impacts and would underpin the development of diagnostic tools that could help forecast shifts in coral reef health under different environmental states. Monitoring, management and active restoration efforts have recently intensified and diversified in response to global declines in coral reef health. Here we propose that regular monitoring of coral reef microorganisms could provide a rapid and sensitive platform for identifying declining ecosystem health that can complement existing management frameworks. By summarising the most common threats to coral reefs, with a particular focus on the Great Barrier Reef, and elaborating on the role of microbes in coral reef health and ecosystem stability, we highlight the diagnostic applicability of microbes in reef management programs. Fundamental to this objective is the establishment of microbial baselines for Australia's coral reefs.
