This project aims to unlock the role hypoxia plays in shaping the healthy functioning of corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs and amplifying hypoxia exposure, yet we have no knowledge of the oxygen thresholds that sustain ‘normal’ coral functioning, or the mechanisms corals’ employ to tolerate hypoxia. This project will couple advanced oxygen sensing, metabolic physiology and functional genomics techniques to transform our understanding of how corals and their associated microbial communities respond to reduced oxygen conditions, which is essential to improve coral reef ecosystem management.

该项目旨在揭示缺氧在塑造珊瑚在空间和时间上的健康功能方面所起的作用。气候变化和土地利用开发正在迅速使浅水珊瑚礁缺氧，并扩大缺氧暴露，但我们不知道维持“正常”珊瑚功能的氧气阈值，或珊瑚用于耐受缺氧的机制。该项目将结合先进的氧气传感，代谢生理学和功能基因组学技术，以改变我们对珊瑚及其相关微生物群落如何应对低氧条件的理解，这对于改善珊瑚礁生态系统管理至关重要。
