Cleopatra II - project summary

Cleopatra2 logo

A warmer climate with less extensive ice cover will lead to higher total primary production in the Arctic, which has the potential to increase the overall secondary production. However, altered climate conditions will affect timing, quantity and quality of ice algal and phytoplankton food sources with implications for the grazers. Depending on the grazers’ ability to adapt to these new conditions, some organisms will be favored more than others, resulting in ecological winners and losers.

In CLEOPATRA II we study Arctic zooplankton and their capability to adapt their current life history strategies and physiology to a changing Arctic. We focus on Calanus glacialis, the key herbivore in Arctic shelf seas. A central element of our approach is to move towards individual-based zooplankton ecology where states, such as lipid reserves, are measured at the level of individuals. We aim at a tight linkage between data collection through field and experimental studies and the modeling work where models deliver predictions for field and laboratory work, securing target-aimed field investigations and well-defined hypotheses. In turn, findings from field and experimental work do not only test model predictions, but also deliver a better basis for improved parameterization and design of models. Long-term data-series acquired through previous projects will be continued and will allow us to include inter-annual variability and different ice-cover scenarios in our investigations. This project includes several national institutions and international collaborators, with strong participation by early career scientists.
