    • Spatial variation in mercury concentrations in polar bear (Ursus maritimus) hair from the Norwegian and Russian Arctic 

      Lippold, Anna; Boltunov, Andrei; Aars, Jon; Andersen, Magnus; Blanchet, Marie-Anne; Dietz, Rune; Eulaers, Igor; Morshina, Tamara N.; Sevastyanov, Vyacheslav S.; Welker, Jeffrey M.; Routti, Heli Anna Irmeli (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-02)
      We examined spatial variation in total mercury (THg) concentrations in 100 hair samples collected between 2008 and 2016 from 87 polar bears (Ursus maritimus) from the Norwegian (Svalbard Archipelago, western Barents Sea) and Russian Arctic (Kara Sea, Laptev Sea, and Chukchi Sea). We used latitude and longitude of home range centroid for the Norwegian bears and capture position for the Russian bears ...

    • Stability of space use in svalbard coastal female polar bears: Intra-individual variability and influence of kinship 

      Brun, Clément; Blanchet, Marie-Anne; Ims, Rolf A.; Aars, Jon (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-28)
      Philopatry influences animal distribution and can lead to a kinship-based spatial structure, where proximity and relatedness are tightly linked. In the Barents Sea region, polar bears (Ursus maritimus) of the coastal ecotype remain year-round within the Svalbard archipelago. This coastal strategy is thought to be stable across years; however, little is known about the intra-individual variability ...
