Lipids and life strategy of Arctic Calanus
... The three Arctic Calanus species, C. finmarchicus, C. glacialis and C. hyperboreus, are the most important herbivores in Arctic seas in terms of species biomass. They play a key role in the lipid-based energy flux in the Arctic, converting low-energy carbohydrates and proteins in ice algae and phyto ...
