Collaborative Research: Life histories of species in the genus Calanus in the North Atlantic and North Pacific Oceans and responses to climate forcing

哲水蚤属的种类主要分布在北大西洋和北太平洋的中型浮游动物中。它们在海洋食物网相互作用中的关键作用已在美国和国际上的GLOBEC计划中得到认可。从实验室实验和海上测量中获得了相当多的生活史特征知识，包括生长、繁殖、死亡率、滞育行为和人口统计学。本计画回顾并综合这些知识，并利用这些知识发展出一个以个体为基础的生活史模式，适用于两个同域种对中的兄弟种，棉花棒蛾和棉花棒蛾。pacificus和C. finmarchicus和C.helgolandicus在北大西洋，这一直是GLOBEC计划和其他最近的研究项目在美国的特别重点，加拿大和欧洲。IBLC模型，然后应用到合理的气候变化情景下的环境食物和温度的强迫每个物种的生活史响应作出预测。该项目涉及培训一名研究生和两名博士后研究人员，评估和预测气候变化对海洋浮游生物种群的影响。它促进与加拿大和欧洲研究人员的国际合作，包括参加在欧洲举办的一个讲习班。推广到更广泛的渔业和管理社区是通过研讨会，信息交流会议与渔民管理人员，包括缅因州渔民？在美国国家海洋和大气管理局的论坛上，与参与缅因州鲱鱼和金枪鱼研究以及气候和渔业相互作用的同事合作开展附属项目。

Species in the genus Calanus are predominant in the mesozooplankton of the North Atlantic and North Pacific Oceans. Their key role in marine food web interactions has been recognized in GLOBEC programs, both in the U.S. and internationally. Considerable knowledge of life history characteristics, including growth, reproduction, mortality, diapause behavior and demography has been acquired from both laboratory experiments and measurements at sea. This project reviews and synthesizes this knowledge and uses it to develop an Individual Based Life Cycle model for sibling species in two sympatric species pairs, C.marshallae and C. pacificus in the North Pacific Ocean and C. finmarchicus and C.helgolandicus in the North Atlantic, that have been the particular focus of GLOBEC programs and other recent research projects in the U.S., Canada and Europe. The IBLC model is then applied to make predictions about the life history response of each species to forcing under reasonable climate change scenarios for ambient food and temperature. The project involves training of a graduate student and two postdoctoral researchers in evaluation and prediction of effects of climate change on marine plankton populations. It fosters international collaboration with Canadian and European researchers, including participation in a workshop in Europe. Outreach to the broader fishing and management community is through seminars, information exchange sessions with fishermen managers, including the Maine Fisherman?s Forum, collaboration in affiliated projects with colleagues involved in herring and tuna research in the Gulf of Maine and in climate and fisheries interactions within NOAA.
