Effects of petrogenic pollutants on North Atlantic and Arctic Calanus copepods: From molecular mechanisms to population impacts
Hansen, Bjørn Henrik; Tarrant, Ann M.; Lenz, Petra H.; Roncalli, Vittoria; Almeda, Rodrigo; Broch, Ole Jacob; Altin, Dag; Tollefsen, Knut-Erik (Peer reviewed; Journal article, 2023)Oil and gas industries in the Northern Atlantic Ocean have gradually moved closer to the Arctic areas, a process expected to be further facilitated by sea ice withdrawal caused by global warming. Copepods of the genus ... -
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 ... -
Mortality and transcriptional effects of inorganic mercury in the marine copepod Calanus finmarchicus
Tollefsen, Knut Erik; Song, You; Høgåsen, Tore; Øverjordet, Ida Beathe; Altin, Dag; Hansen, Bjørn Henrik (Journal article; Peer reviewed, 2017)Inorganic mercury (Hg) is highly toxic to organisms including crustaceans and displays multiple toxic modes of action (MoA). The main aim of this investigation was to assess the acute and sublethal toxicity mediated by ... -
