Abstract

Marine bacterioplankton underpin the health and function of coral reefs and respond in a rapid and sensitive manner to environmental changes that affect reef ecosystem stability. Numerous meta-omics surveys over recent years have documented persistent associations of opportunistic seawater microbial taxa, and their associated functions, with metrics of environmental stress and poor reef health (e.g. elevated temperature, nutrient loads and macroalgae cover). Through positive feedback mechanisms, disturbance-triggered heterotrophic activity of seawater microbes is hypothesised to drive keystone benthic organisms towards the limit of their resilience and translate into shifts in biogeochemical cycles which influence marine food webs, ultimately affecting entire reef ecosystems. However, despite nearly two decades of work in this space, a major limitation to using seawater microbes in reef monitoring is a lack of a unified and focused approach that would move beyond the indicator discovery phase and towards the development of rapid microbial indicator assays for (near) real-time reef management and decision-making. By reviewing the current state of knowledge, we provide a comprehensive framework (defined as five phases of research and innovation) to catalyse a shift from fundamental to applied research, allowing us to move from descriptive to predictive reef monitoring, and from reactive to proactive reef management.

将海水微生物纳入预测性珊瑚礁监测的前进之路。
海洋浮游细菌支撑着珊瑚礁的健康和功能,并对影响珊瑚礁生态系统稳定性的环境变化做出快速而敏感的反应。近年来的大量元组学调查记录了机会性海水微生物类群及其相关功能与环境压力和珊瑚礁健康状况(如温度升高、营养负荷和大型藻类覆盖)的持续关联。据推测,通过正反馈机制,扰动触发的海水微生物异养活动将推动关键底栖生物达到其恢复能力的极限,并转化为影响海洋食物网的生物地球化学循环的变化,最终影响整个珊瑚礁生态系统。然而,尽管在这一领域开展了近二十年的工作,在珊瑚礁监测中使用海水微生物的一个主要限制因素是缺乏一种统一的、有针对性的方法,这种方法可以超越指标发现阶段,发展快速微生物指标测定,用于(近)实时珊瑚礁管理和决策。通过回顾当前的知识状况,我们提供了一个综合框架(定义为研究与创新的五个阶段),以促进从基础研究到应用研究的转变,使我们能够从描述性珊瑚礁监测转变为预测性珊瑚礁监测,从被动反应转变为主动珊瑚礁管理。

期刊介绍: Microorganisms, omnipresent across Earth's diverse environments, play a crucial role in adapting to external changes, influencing Earth's systems and cycles, and contributing significantly to agricultural practices. Through applied microbiology, they offer solutions to various everyday needs. Environmental Microbiome recognizes the universal presence and significance of microorganisms, inviting submissions that explore the diverse facets of environmental and applied microbiological research.
