(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-04)
      Environmental change and increasing levels of human activity are threats to marine mam- mals in the Arctic. Identifying marine mammal hot - spots and areas of high species richness are essential to help guide management and conservation efforts. Herein, space use based on biotelemetric tracking devices deployed on 13 species (ringed seal <i>Pusa hispida</i>, bearded seal <i>Erignathus ...

      There has been a considerable number of reports on Hg concentrations in Arctic mammals since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to mercury (Hg) in Arctic biota in 2010 and 2018. Here, we provide an update on the state of the knowledge of health risk associated with Hg concentrations in Arctic marine and terrestrial mammal ...

    • 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 ...
