1026358HofmannTitle: U.S.-New Zealand Dissertation Enhancement: Biochemical Consequences of Ocean Acidification on Larval Development in a Temperate Sea Urchin.This award supports a doctoral dissertation enhancement project between Dr. Gretchen Hofmann and her student Paul Matson in the Department of Ecology, Evolution and Marine Biology at the University of California, Santa Barbara and Dr. Mary Sewell in the School of Biological Sciences at the University of Auckland in New Zealand. Ocean acidification (OA) is expected to be one of the most pervasive impacts of global climate change on marine systems. While calcifying organisms are predicted to be at greatest risk from decreased ocean pH, many other taxa may be at risk, particularly during environmentally sensitive early life-history stages. The project will investigate the impacts of ocean acidification on the physiology and biochemistry of larval sea resources during larval development. Lipids represent the primary energy source fueling larval development in a large number of marine taxa. The abundance of particular classes of lipids such as triglyceride, an energy storage lipid, can be a useful metric of physiological state. The rate at which these lipids are utilized during development may also provide useful information regarding larval metabolism. There is sufficient overlap of interests between the University of California and the University of Auckland to indicate that they can successfully pursue the activities proposed and that the interaction will benefit both sides. Results from this research will increase our knowledge regarding the potential costs of developing larvae in an acidified ocean, and what impacts it may have on populations in near-future climate change scenarios. It will also provide useful insights into changes in metabolism. This research will provide the US graduate student an excellent opportunity to receive a global research experience. It is anticipated that he will maintain contacts and collaborations with the New Zealand researchers and students throughout his career

1026358HofmannTitle：美国-新西兰学位论文增强：海洋酸化对温带海洋城市幼虫发育的生化后果。该奖项支持加州大学圣巴巴拉分校生态、进化和海洋生物系的Gretchen Hofmann博士和她的学生Paul Matson博士与新西兰奥克兰大学生物科学学院的Mary Sewell博士的博士论文增强项目。海洋酸化预计将是全球气候变化对海洋系统最普遍的影响之一。尽管据预测，钙化生物因海洋pH值下降而面临的风险最大，但许多其他分类群也可能面临风险，特别是在对环境敏感的早期生活史阶段。该项目将调查海洋酸化对幼虫发育期间海洋幼虫资源的生理和生化的影响。在大量海洋类群中，脂类是幼虫发育的主要能量来源。甘油三酯是一种储存能量的脂类，它的丰富程度可以作为生理状态的一个有用的衡量标准。这些脂肪在发育过程中的利用速度也可能提供有关幼虫新陈代谢的有用信息。加州大学和奥克兰大学之间的利益有足够的重叠，这表明他们可以成功地开展拟议的活动，这种互动将对双方都有利。这项研究的结果将增加我们关于在酸化的海洋中培育幼虫的潜在成本以及在不久的将来气候变化情景下可能对种群产生什么影响的知识。它还将为新陈代谢的变化提供有用的见解。这项研究将为美国研究生提供一个获得全球研究经验的绝佳机会。预计他在整个职业生涯中将与新西兰的研究人员和学生保持联系和合作
