Increased sea temperatures and decreased ocean pH due to human induced climate change will have both direct and indirect impacts on marine life. This project is designed to investigate variation in the physiological responses of reef fish to projected end-of-the-century environmental conditions. Temperature is perhaps the most significant abiotic factor influencing the performance and fitness of marine organisms and decreased pH, or ocean acidification, has been shown to impose trade offs to fish between behavioral and physiological performance. Such research will help scientists to better understand how climate change might impact population dynamics and the long term viability of economically valuable species. This study will be a collaborative effort between the fellow and Dr. Jodie Rummer of James Cook University in Queensland, Australia. Dr. Rummer is a leading expert in fish physiology and behavior at the ARC Centre of Excellence for Coral Reef Studies, an international hub of tropical research.To investigate how the physiology of particular reef associated fish species are impacted by increasing temperature and ocean acidification, this project will quantify the changes to various aspects of fish metabolism and swimming performance following sustained exposure to realistic, near future climate conditions. The results from this EAPSI award will, in part, contribute to knowledge of species-specific, whole organism responses to changing environmental conditions and will identify potential mechanisms underlying altered performance. Fish play key roles in marine food webs and are a valuable source of protein for humans. As a consequence, information linking individual performance to population and community scale dynamics will help shape marine management strategies to ensure the persistence of coral reef biodiversity in a rapidly changing world.This award under the East Asia and Pacific Summer Institutes program supports summer research by a U.S. graduate student and is jointly funded by NSF and the Australian Academy of Science.

人类引起的气候变化导致海水温度升高和海洋 pH 值降低，将对海洋生物产生直接和间接影响。该项目旨在研究珊瑚鱼对预计的本世纪末环境条件的生理反应的变化。温度可能是影响海洋生物性能和适应性的最重要的非生物因素，pH 值下降或海洋酸化已被证明会影响鱼类的行为和生理性能。此类研究将帮助科学家更好地了解气候变化可能如何影响种群动态和具有经济价值的物种的长期生存能力。这项研究将由该研究员与澳大利亚昆士兰州詹姆斯库克大学的 Jodie Rummer 博士合作完成。 Rummer 博士是国际热带研究中心 ARC 珊瑚礁研究卓越中心的鱼类生理学和行为方面的领先专家。为了研究特定珊瑚礁相关鱼类的生理学如何受到温度升高和海洋酸化的影响，该项目将量化鱼类在持续暴露于现实的、近期的气候条件下新陈代谢和游泳性能各个方面的变化。该 EAPSI 奖项的结果将在一定程度上有助于了解物种特异性、整个生物体对不断变化的环境条件的反应，并将确定潜在的性能改变机制。鱼类在海洋食物网中发挥着关键作用，是人类宝贵的蛋白质来源。因此，将个人表现与人口和社区规模动态联系起来的信息将有助于制定海洋管理战略，以确保珊瑚礁生物多样性在快速变化的世界中持续存在。该奖项属于东亚和太平洋夏季研究所计划，支持美国研究生的夏季研究，由美国国家科学基金会和澳大利亚科学院共同资助。
