      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 ...
    • 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; Covaci, Adrian; Eens, Marcel; Halley, Duncan John; Moum, Truls Borg; Ims, Rolf Anker; Erikstad, Kjell E (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 ...
    • Per- and polyfluoroalkyl substances in plasma and feathers of nestling birds of prey from northern Norway 

      Gómez-Ramírez, P.; Bustnes, Jan Ove; Eulaers, I; Herzke, Dorte; Johnsen, Trond Vidar; Lepoint, G; Perez-Garcia, JM; García-Fernández, A.J.; Jaspers, Veerle (Journal article; Peer reviewed, 2017)
      Plasma samples from nestlings of two top predators, White‐tailed eagle (Haliaeetus albicilla) and Northern goshawk (Accipiter gentilis) from northern Norway were analysed for a wide range of PFASs. Body feathers from the ...
    • Trace element concentrations in feathers and blood of Northern goshawk (Accipiter gentilis) nestlings from Norway and Spain 

      Dolan, Kevin J.; Ciesielski, Tomasz Maciej; Lierhagen, Syverin; Eulaers, Igor; Nygård, Torgeir; Johnsen, Trond Vidar; Gómez-Ramírez, Pilar; García-Fernández, Antonio J.; Bustnes, Jan Ove; Ortiz-Santaliestra, Manuel E.; Jaspers, Veerle (Journal article; Peer reviewed, 2017)
      Information on trace element pollution in the terrestrial environment and its biota is limited compared to the marine environment. In the present study, we collected body feathers and blood of 37 Northern goshawk (Accipiter ...
