    • Can a key boreal Calanus copepod species now complete its life-cycle in the Arctic? Evidence and implications for Arctic food-webs 

      Tarling, Geraint A.; Freer, Jennifer J.; Banas, Neil S.; Belcher, Anna; Blackwell, Mayleen; Castellani, Claudia; Cook, Kathryn B.; Cottier, Finlo Robert; Daase, Malin; Johnson, Magnus L.; Last, Kim S.; Lindeque, Penelope K.; Mayor, Daniel J.; Mitchell, Elaine; Parry, Helen E.; Speirs, Douglas C.; Stowasser, Gabriele; Wootton, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-29)
      The changing Arctic environment is affecting zooplankton that support its abundant wildlife. We examined how these changes are influencing a key zooplankton species, Calanus finmarchicus, principally found in the North Atlantic but expatriated to the Arctic. Close to the ice-edge in the Fram Strait, we identified areas that, since the 1980s, are increasingly favourable to C. finmarchicus. Field-sampling ...

    • Carbon and Lipid Contents of the Copepod Calanus finmarchicus Entering Diapause in the Fram Strait and Their Contribution to the Boreal and Arctic Lipid Pump 

      Tarling, Geraint A.; Belcher, Anna; Blackwell, Mayleen; Castellani, Claudia; Cook, Kathryn Barbara; Cottier, Finlo Robert; Dewar-Fowler, Victoria; Freer, Jennifer J.; Gerrish, Laura; Johnson, Magnus L.; Last, Kim S.; Lindeque, Penelope Kate; Mayor, Daniel J.; Parry, Helen E.; Stowasser, Gabriele; Wootton, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-28)
      The boreal copepod Calanus finmarchicus sequesters substantial amounts of carbon (C) in the deep layers of the North Atlantic Ocean through their contribution to the “lipid pump.” This pump is driven by these zooplankton descending from the surface layers to spend prolonged periods at depth during which time they metabolise substantial lipid reserves and a fraction suffer mortality. C. finmarchicus ...
