    • Potential effects of petroleum pollution and increasing water temperature on life-history traits in polar cod (Boreogadus saida) 

      Bender, Morgan Lizabeth; Frantzen, Marianne; Geoffroy, Maxime; Meador, James P.; Nahrgang, Jasmine (Conference object; Konferansebidrag, 2017)

    • Quantifying the consequence of applying conservative assumptions in the assessment of oil spill effects on polar cod (Boreogadus saida) populations 

      de Vries, Pepjin; Tamis, Jacqueline; Nahrgang, Jasmine; Frantzen, Marianne; Jak, Robbert; Klok, Chris; van den Heuvel-Greve, Martine J; Hemerik, Lia (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-23)
      In order to assess the potential impact from oil spills and decide the optimal response actions, prediction of population level effects of key resources is crucial. These assessments are usually based on acute toxicity data combined with precautionary assumptions because chronic data are often lacking. To better understand the consequences of applying precautionary approaches, two approaches for ...

    • Seasonal and spatial variations in biomarker baseline levels within Arctic populations of mussels (Mytilus spp.) 

      Storhaug, Ekaterina; Nahrgang, Jasmine; Pedersen, Kristine Bondo; Brooks, Steven; Petes, Laura; Bakhmet, Igor N.; Frantzen, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-28)
      Climate change and pollution resulting from human activities in the Arctic require reliable monitoring systems in sentinel species. Mytilus spp. are used as sentinel species all around the world. The use of Mytilus spp. in environmental monitoring requires knowledge about natural variations in pollution biomarkers. Seasonal variations in baseline levels of biomarkers were studied over a year in the ...

    • Spawning time in adult polar cod (Boreogadus saida) altered by crude oil exposure, independent of food availability 

      Strople, Leah Catherine; Vieweg, Ireen; Yadetie, Fekadu; Odei, Derrick Kwame; Thorsen, Anders; Karlsen, Odd André; Goksøyr, Anders; Sørensen, Lisbet; Sarno, Antonio; Hansen, Bjørn Henrik; Frantzen, marianne; Hansen, Øyvind J; Puvanendran, Velmurugu; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-03)
      Fish early life stages are well known for their sensitivity to crude oil exposure. However, the effect of crude oil exposure on adults and their gametes during their spawning period is not well studied. Polar cod, a key arctic fish, may be at risk for crude oil exposure during this potentially sensitive life stage. Additionally, this species experiences lower food availability during their spawning ...

    • Susceptibility of polar cod (Boreogadus saida) to a model carcinogen 

      Lerebours, Adélaïde; Murzina, Svetlana; Song, You; Tollefsen, Knut-Erik; Benedetti, Maura; Regoli, Francesco; Rotchell, Jeanette M.; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-27)
      Studies that aim to characterise the susceptibility of the ecologically relevant and non-model fish polar cod (Boreogadus saida) to model carcinogens are required. Polar cod were exposed under laboratory conditions for six months to control, 0.03 μg BaP/g fish/week and 0.3 μg BaP/g fish/week dietary benzo(a)pyrene (BaP), a reference carcinogen. The concentrations of the 3-OH-BaP bile metabolite and ...

    • Transcriptome responses in polar cod (Boreogadus saida) liver slice culture exposed to benzo[a]pyrene and ethynylestradiol: insights into anti-estrogenic effects 

      Yadetie, Fekadu; Brun, Nadja R; Vieweg, Ireen; Nahrgang, Jasmine; Karlsen, Odd André; Goksøyr, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-17)
      Polar cod (<i>Boreogadus saida</i>) is a key species in the arctic marine ecosystem vulnerable to effects of pollution, particularly from petroleum related activities. To facilitate studying the effects of those pollutants, we adapted a precision-cut liver slice culture protocol for this species. Using this system on board a research vessel, we studied gene expression in liver slice after exposure ...

    • Transcriptomic analysis reveals dose-dependent modes of action of benzo(a)pyrene in polar cod (Boreogadus saida) 

      Song, You; Nahrgang, Jasmine; Tollefsen, Knut Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-21)
      Polar cod (<i>Boreogadus saida</i>) has been used as a model Arctic species for hazard assessment of environmental stressors such as polycyclic aromatic hydrocarbons (PAHs). However, most of the PAH studies using polar cod rely on targeted biomarker-based analysis thus may not adequately address the complexity of the toxic mechanisms of the stressors. The present study was performed to develop a ...
