This project aims to examine the effects of ocean acidification on coral reef fishes due to increasing atmospheric carbon dioxide (CO2). Physiological performance of fish vary under elevated CO2, but behaviour is consistently, negatively impacted. This project aims to investigate evolutionary trade-offs between behaviour and performance, physiological mechanisms key to compromising, maintaining, or enhancing metabolic performance under elevated CO2, and the importance of habitat in how fish respond to elevated CO2. As fish play critical roles in marine ecosystems by structuring food webs and driving ecological processes, this information will be critical for predicting the effects of ocean acidification on marine ecosystems and biodiversity.

该项目旨在研究由于大气二氧化碳（CO2）增加而导致的海洋酸化对珊瑚礁鱼类的影响。鱼类的生理表现在CO2浓度升高的情况下会有所不同，但行为却始终受到负面影响。该项目旨在研究行为和性能之间的进化权衡，在CO2升高下妥协，维持或增强代谢性能的关键生理机制，以及栖息地对鱼类如何应对CO2升高的重要性。由于鱼类通过构建食物网和驱动生态过程在海洋生态系统中发挥着关键作用，因此这些信息对于预测海洋酸化对海洋生态系统和生物多样性的影响至关重要。
