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.

该项目旨在释放缺氧在塑造珊瑚在时空上的健康功能方面发挥的作用。气候变化和土地利用的发展正在迅速使浅水珊瑚礁脱氧，并扩大了缺氧的暴露，但是我们不知道维持“正常”珊瑚功能的氧阈值，或者珊瑚的机制雇员可以容忍缺氧。该项目将伴随先进的氧气感应，代谢生理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响应减少的氧气条件的理解，这对于改善珊瑚礁生态系统管理至关重要。
