    • Diet and metabolic state are the main factors determining concentrations of perfluoroalkyl substances in female polar bears from Svalbard 

      Tartu, Sabrina; Bourgeon, Sophie; Aars, Jon; Andersen, Magnus; Lone, Karen; Jenssen, Bjørn Munro; Polder, Anuschka; Thiemann, Gregory W.; Torget, Vidar; Welker, Jeffrey Martin; Routti, Heli Anna Irmeli (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-03)
      Perfluoroalkyl substances (PFASs) have been detected in organisms worldwide, including Polar Regions. The polar bear (Ursus maritimus), the top predator of Arctic marine ecosystems, accumulates high concentrations of PFASs, which may be harmful to their health. The aim of this study was to investigate which factors (habitat quality, season, year, diet, metabolic state [i.e. feeding/fasting], breeding ...

    • Multiple-stressor effects in an apex predator: combined influence of pollutants and sea ice decline on lipid metabolism in polar bears 

      Tartu, Sabrina; Lille-Langøy, Roger; Størseth, Trond Røvik; Bourgeon, Sophie; Brunsvik, Anders; Goksøyr, Anders; Jenssen, Bjørn Munro; Polder, Anuschka; Thiemann, Gregory W.; Torget, Vidar; Routti, Heli (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-28)
      There is growing evidence from experimental and human epidemiological studies that many pollutants can disrupt lipid metabolism. In Arctic wildlife, the occurrence of such compounds could have serious consequences for seasonal feeders. We set out to study whether organohalogenated compounds (OHCs) could cause disruption of energy metabolism in female polar bears ( Ursus maritimus ) from ...
