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.

卡拉努斯属的物种在北大西洋和北太平洋的中龙兰克顿占主导地位。无论是在美国还是国际上，它们在海洋食品网络互动中的关键作用已得到认可。已经从实验室实验和海上测量中获取了有关生活历史特征的广泛了解，包括生长，繁殖，死亡率，抑郁行为和人口统计学。该项目回顾并综合了这一知识，并使用它来开发一个基于单个的生命周期模型，该模型在两个同胞物种对中，分别是北太平洋大洋的Marshallae和C. c.marshallae和C. Pacificus，以及C. finmarchicus和C. finmarchicus和C. helgolandicus，以及北大西洋的Helgolandicus，它们是Globec计划和美国最近在美国，加拿大和加拿大和加拿大和欧洲的Globec计划和其他最新研究项目的焦点。然后，应用IBLC模型来预测每个物种对在合理的气候变化场景下对环境食物和温度的迫使迫使的寿命响应。该项目涉及对研究生和两名博士后研究人员的培训，以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，包括参加欧洲的研讨会。向更广泛的捕鱼和管理社区推广是通过研讨会，与渔民经理的信息交流会议，包括缅因州渔夫论坛，在缅因州海湾以及NOAA中涉及鲱鱼和金枪鱼研究的同事与鲱鱼和金枪鱼研究的合作。
