EAPSI:Impacts of Projected Climate Change on Physiological Performance of Coral Reef Fishes

由于人类引起的气候变化，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的影响。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值降低或海洋酸化已被证明会在行为性能和生理性能之间施加权衡。这样的研究将帮助科学家更好地了解气候变化如何影响种群动态和经济价值物种的长期生存能力。这项研究将由该研究员和澳大利亚昆士兰詹姆斯库克大学的朱迪·鲁默博士共同完成。Rummer博士是ARC卓越珊瑚礁研究中心（ARC center of Excellence for Coral Reef Studies）的鱼类生理学和行为方面的权威专家，该中心是热带研究的国际中心。为了研究特定珊瑚礁相关鱼类的生理如何受到温度升高和海洋酸化的影响，该项目将量化持续暴露于现实的，不久的将来的气候条件下，鱼类代谢和游泳性能的各个方面的变化。这项EAPSI奖励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，并将确定改变性能的潜在机制。鱼类在海洋食物网中扮演着关键角色，是人类宝贵的蛋白质来源。因此，将个体表现与种群和群落规模动态联系起来的信息将有助于形成海洋管理战略，以确保在快速变化的世界中珊瑚礁生物多样性的持久性。该奖项由美国国家科学基金会和澳大利亚科学院共同资助，隶属于东亚和太平洋暑期研究所项目，支持美国研究生进行暑期研究。

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.
