RUI: Synergistic effects of Ocean Acidification and Warming on Larval Development in Antarctic Fishes

预计海洋酸化和温度升高将是全球气候变化在下个世纪对极地海洋生态系统的主要影响。虽然最近的研究主要集中在这些驱动因素对钙化生物的影响上，但对这些变化如何影响脊椎动物却知之甚少。本研究将重点研究两种南极鱼类：bernachchii Trematomus和paothenia borchgrevinki。鱼卵和幼鱼将在麦克默多湾收集，并在不同的温度和pH值下饲养。现代技术将用于检查生理、生长、发育和基因表达在短期和长期时间尺度上的后续变化。这些结果将填补我们关于非钙化生物对pH值和温度预测变化的反应的知识空白。将通过出版物以及在国家和国际会议上的发言广泛传播研究结果；原始数据也将通过开放获取的基于网络的数据库提供。本项目将支持3名研究生和3名本科生的研究和培训。此外，本计画将促进生物导论课程中气候变迁与海洋酸化两个模组的发展。

Ocean acidification and increased temperatures are projected to be the primary impacts of global climate change on polar marine ecosystems over the next century. While recent research has focused on the effects of these drivers on calcifying organisms, less is known about how these changes may affect vertebrates. This research will focus on two Antarctic fishes, Trematomus bernacchii and Pagothenia borchgrevinki. Fish eggs and larvae will be collected in McMurdo Sound and reared under different temperature and pH regimes. Modern techniques will be used to examine subsequent changes in physiology, growth, development and gene expression over both short and long timescales. The results will fill a missing gap in our knowledge about the response of non-calcifying organisms to projected changes in pH and temperature. Results will be widely disseminated through publications as well as through presentations at national and international meetings; raw data will also be made available through open-access, web-based databases. This project will support the research and training of three graduate and three undergraduate students. As well, this project will foster the development of two modules on climate change and ocean acidification for an Introduction to Biology course.
