 US GLOBEC Pan-Regional Synthesis
Life histories of species in the genus Calanus in the North Atlantic and North Pacific Oceans and responses to climate forcing
Recent Events:
On March 22, 2010, we held a workshop on Calanus life history modeling and data availability, as part of a RARGOM theme session and in conjunction with the ICES WGZE meeting, in Portland, ME at the Portland Regency Hotel. You can view the agenda, presentations, and a report from the workshop here. In addition we have begun to compile a list of available data sets for various aspects of Calanus biology and life history, which can be accessed here. If you know of any other data sets we should append to the current lists, please click here to access a web-based browser form.

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.
