Microorganisms underpin marine ecosystem health, yet there is limited understanding of how they will respond to different environmental pressures. This project will resolve this critical knowledge gap by developing a unique molecular platform for deriving quantitative stress thresholds for microbial communities inhabiting key reef habitats (seawater, sediments, invertebrates). Quantifying how reef microorganisms respond to a broad suite of environmental perturbations (temperature, nutrients, contaminants), will generate stress-response data that can be incorporated alongside eukaryotic data in environmental assessments, greatly improving the ecological relevance and reliability of risk and vulnerability assessments.

微生物是海洋生态系统健康的基础，但人们对它们如何应对不同环境压力的了解有限。该项目将通过开发一个独特的分子平台来解决这一关键的知识差距，该平台用于推导居住在关键珊瑚礁栖息地（海水、沉积物、无脊椎动物）的微生物群落的定量应激阈值。量化珊瑚礁微生物对一系列环境扰动（温度、营养物质、污染物）的反应，将生成应激反应数据，这些数据可以与真核数据一起纳入环境评估中，从而大大提高风险和脆弱性评估的生态相关性和可靠性。
