US-NZ Dissertation Enhancement: Biochemical consequences of ocean acidification on larval development in a temperate sea urchin

题目：美国-新西兰论文增强：海洋酸化对温带海胆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、进化和海洋生物学系的Gretchen Hofmann博士和她的学生Paul Matson以及新西兰奥克兰大学生物科学学院的Mary Sewell博士之间的博士论文增强项目。海洋酸化（OA）被认为是全球气候变化对海洋系统最普遍的影响之一。虽然钙化生物预计将面临海洋pH值下降的最大风险，但许多其他分类群也可能面临风险，特别是在环境敏感的生活史早期阶段。该项目将研究海洋酸化对幼鱼发育过程中海洋资源生理生化的影响。在许多海洋分类群中，脂类是幼虫发育的主要能量来源。特定种类的脂质如甘油三酯（一种能量储存脂质）的丰度可以作为衡量生理状态的有用指标。这些脂质在发育过程中被利用的速率也可以提供有关幼虫代谢的有用信息。加州大学和奥克兰大学之间有足够的利益重叠，表明他们可以成功地开展拟议的活动，这种互动将使双方受益。这项研究的结果将增加我们对酸化海洋中发育幼虫的潜在成本的了解，以及在不久的将来气候变化情景下它对种群的影响。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。预计他将在整个职业生涯中与新西兰的研究人员和学生保持联系和合作

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
