    • A Crude Awakening: Effects of Crude Oil on Lipid Metabolism in Calanoid Copepods Terminating Diapause 

      Skottene, Elise; Tarrant, Ann; Olsen, Anders; Altin, Dag; Hansen, Bjørn Henrik; Choquet, Marvin; Olsen, Rolf Erik; Jenssen, Bjørn Munro (Journal article; Peer reviewed, 2019)
      Calanus finmarchicus and Calanus glacialis are keystone zooplankton species in North Atlantic and Arctic marine ecosystems because they form a link in the trophic transfer of nutritious lipids from phytoplankton to predators ...

    • Lipid metabolism in Calanus finmarchicus is sensitive to variations in predation risk and food availability 

      Skottene, Elise; Tarrant, Ann M.; Altin, Dag; Olsen, Rolf Erik; Choquet, Marvin; Kvile, Kristina Øie (Peer reviewed; Journal article, 2020)
      Late developmental stages of the marine copepods in the genus Calanus can spend extended periods in a dormant stage (diapause) that is preceded by the accumulation of large lipid stores. We assessed how lipid metabolism ...

    • Photoperiodism and overwintering in boreal and sub-Arctic Calanus finmarchicus populations 

      Coguiec, Estelle; Last, Kim S.; Cohen, Jonathan H.; Hobbs, Laura; Choquet, Marvin; Ershova, Elizaveta; Berge, Jørgen; Daase, Malin (Journal article, 2023)
      ABSTRACT: The copepod Calanus finmarchicus, a key species in the North Atlantic, generally spends the non-productive season by descending into deep waters and entering diapause, a physiological state characterized by reduced ...

    • The β-oxidation pathway is downregulated during diapause termination in Calanus copepods 

      Skottene, Elise; Tarrant, Ann M.; Olsen, Anders Johny; Altin, Dag; Østensen, Mari-Ann; Hansen, Bjørn Henrik; Choquet, Marvin; Jenssen, Bjørn Munro; Olsen, Rolf Erik (Journal article; Peer reviewed, 2019)
      Calanus copepods are keystone species in marine ecosystems, mainly due to their high lipid content, which is a nutritious food source for e.g. juvenile fish. Accumulated lipids are catabolized to meet energy requirements ...
