      Capsule Great Skuas Stercorarius skua wintering in different areas spent different amounts of time in flight (foraging or searching for food) and so may be experiencing different feeding conditions. Aims To compare the ...

    • Anti-parasite treatment and blood biochemistry in raptor nestlings 

      Hanssen, Sveinn Are; Sonne, Christian; Bustnes, Jan Ove; Schnug, Lisbeth; Bourgeon, Sophie; Ballesteros, Manuel; Eulaers, Igor; Moum, Truls Borg; Johnsen, Trond Vidar; Kjelgaard-Hansen, Mads; Herzke, Dorte; Jaspers, Veerle; Covaci, Adrian; Eens, Marcel; Halley, Duncan John; Erikstad, Kjell Einar; Ims, Rolf Anker (Journal article; Peer reviewed, 2017)
      We investigated the effects of parasite removal on various blood clinical–chemical variables (BCCVs). BCCVs are indicators of health, reflecting, e.g., homeostasis of liver, kidney function, and bone metabolism. The study ...

    • Climate change and the increasing impact of polar bears on bird populations 

      Prop, Jouke; Aars, Jon; Bårdsen, Bård-Jørgen; Hanssen, Sveinn Are; Bech, Claus; Bourgeon, Sophie; Fouw, Jimmy de; Gabrielsen, Geir W.; Lang, Johannes; Noreen, Elin; Oudman, Thomas; Sittler, Benoit; Tombre, Ingunn; Wolters, Eva; Moe, Børge; Stempniewicz, Lech (Peer reviewed; Journal article, 2015)
      The Arctic is becoming warmer at a high rate, and contractions in the extent of sea ice are currently changing the habitats of marine top-predators dependent on ice. Polar bears (Ursus maritimus) depend on sea ice for ...

    • Don't mind if I do: Arctic humpback whales respond to winter foraging opportunities before migration 

      Kettemer, Lisa Elena; Ramm, Theresia; Broms, Fredrik Björn; Biuw, Martin; Blanchet, Marie-Anne; Bourgeon, Sophie; Dubourg, Paul; Ellendersen, Anna C.
