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

海洋酸化和温度升高预计将是下个世纪全球气候变化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有机体的影响上，但对于这些变化如何影响脊椎动物却知之甚少。这项研究将集中在两种南极鱼类，雷子鱼和Pagothenia borchgrevinki。鱼卵和仔鱼将被收集在麦克默多海峡，并在不同的温度和pH条件下饲养。现代技术将被用来检查随后在短时间和长时间范围内的生理、生长、发育和基因表达的变化。这一结果将填补我们关于非钙化生物体对预计的pH和温度变化的反应的知识空白。成果将通过出版物以及在国家和国际会议上的介绍广泛传播；还将通过开放获取的网络数据库提供原始数据。该项目将支持三名研究生和三名本科生的研究和培养。此外，该项目还将促进为《生物学导论》课程开发关于气候变化和海洋酸化的两个单元。

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.
