      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 L.B.; 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 ...
    • Antiparasite treatments reduce humoral immunity and impact oxidative status in raptor nestlings 

      Hanssen, Sveinn Are; Bustnes, Jan Ove; Schnug, Lisbeth; Bourgeon, Sophie; Johnsen, Trond Vidar; Ballesteros, Manuel; Sonne, Christian; Herzke, Dorte; Eulaers, Igor; Jaspers, Veerle L.B.; Covaci, Adrian; Eens, Marcel; Halley, Duncan John; Moum, Truls Borg; Ims, Rolf Anker; Erikstad, Kjell Einar (Journal article; Peer reviewed, 2013)
      Parasites are natural stressors that may have multiple negative effects on their host as they usurp energy and nutrients and may lead to costly immune responses that may cause oxidative stress. At early stages, animals may ...
    • The relationship between daily behavior, hormones, and a color dimorphism in a seabird under natural continuous light 

      Huffeldt, Nicholas Per; Tigano, Anna; Erikstad, Kjell Einar; Goymann, Wolfgang; Jenni-Eiermann, Susanne; Moum, Truls Borg; Reiertsen, Tone Kristin (Peer reviewed; Journal article, 2021)
      The predictable oscillation between the light of day and the dark of night across the diel cycle is a powerful selective force that has resulted in anticipatory mechanisms in nearly all taxa. At polar latitude, however, ...
