    • Pelagic vs coastal - Key drivers of pollutant levels in Barents Sea polar bears with contrasted space-use strategies 

      Blévin, Pierre; Aars, Jon; Andersen, Magnus; Blanchet, Marie-Anne; Hanssen, Linda; Herzke, Dorte; Jeffreys, Rachel M.; Nordøy, Erling Sverre; Pinzone, Marianna; de la Vega, Camille; Routti, Heli Anna Irmeli (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-11)
      In the Barents Sea, pelagic and coastal polar bears are facing various ecological challenges that may explain the difference in their pollutant levels. We measured polychlorinated biphenyls, organochlorine pesticides, polybrominated diphenyl ethers in fat, and perfluoroalkyl substances in plasma in pelagic and coastal adult female polar bears with similar body condition. We studied polar bear feeding ...

    • Space-use strategy affects energy requirements in Barents Sea polar bears 

      Blanchet, Marie-Anne; Aars, Jon; Andersen, Magnus; Routti, Heli (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-02)
      Polar bears Ursus maritimus are currently facing rapid environmental changes with loss of sea ice and shifts in their prey distribution. Two distinct ecotypes exist in the Barents Sea, where sea ice is decreasing at the highest rate in the Arctic. Coastal bears remain within the Archipelago of Svalbard year-round, whereas offshore bears follow the marginal ice zone (MIZ). We explored these 2 ecotypes’ ...
