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

在北大西洋和北太平洋的中浮游动物中占主导地位的是Calanus属的物种。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项目中得到认可。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。本项目回顾和综合了这些知识，并利用这些知识开发了两个同域物种对兄弟物种的基于个体的生命周期模型，这两个物种对是北太平洋的C.marshallae和c.pacificus，北大西洋的c.finmarchicus和C.helgolandicus，这是GLOBEC项目和美国、加拿大和欧洲其他近期研究项目的重点。然后，应用IBLC模型预测在合理的气候变化情景下，每个物种对环境食物和温度的强迫的生活史响应。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。它促进了与加拿大和欧洲研究人员的国际合作，包括参加欧洲的一个研讨会。与更广泛的渔业和管理界的联系是通过研讨会和与渔民管理人员(包括缅因州渔民？在缅因湾从事鲱鱼和金枪鱼研究的同事，以及在美国国家海洋和大气管理局从事气候和渔业相互作用研究的同事，在附属项目上进行合作。

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.
