This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the first time, couple advanced oxygen sensing, metabolic physiology, coral reproductive and stress biology to transform our understanding of oxygen thresholds that are diagnostic of reduced coral competitive fitness across life stages (adults, juveniles, larvae), needed to improve coral reef ecosystem management.

该项目旨在揭示低氧在塑造健康珊瑚中的作用。气候变化和土地利用开发正在使浅水珊瑚礁迅速缺氧，但我们不知道氧气供应的减少如何影响决定珊瑚复原力的关键生命史因素：生长、繁殖和应激耐受力。该项目联合了一个多学科的专家团队，首次将先进的氧气传感，代谢生理学，珊瑚生殖和压力生物学结合起来，以改变我们对氧气阈值的理解，这些氧气阈值是诊断珊瑚在生命阶段（成年人，青少年，幼虫）竞争力下降的诊断，这是改善珊瑚礁生态系统管理所需的。
