Sigrún H. Jónasdóttir, Senior Researcher at DTU Aqua, will present her research:

Everybody seems to know the copepod Calanus finmarchicus, (Rauðáta) - the dominant zooplankton species around Iceland. Here in Iceland it is the copepod with which the fish stocks rise and fall, further north - in the Arctic waters it is the invader from the south: the guy that is moving with warmer waters northward replacing its fatter and bigger cousin species and potentially causing major changes in Arctic food web as we know it. In this presentation I will give a short overview of this species in the North Atlantic. Why is it so important? I will focus on its lipid biology and introduce its lesser known importance, as an active player in the biogeochemical carbon cycle of the oceans.
