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

    • Bird feathers as a biomonitor for environmental pollutants: Prospects and pitfalls 

      Jaspers, Veerle; Covaci, Adrian; Herzke, Dorte; Eulaers, Igor; Eens, Marcel (Journal article; Peer reviewed, 2019)
      Due to increasing amounts of hazardous chemicals released into the environment, there is a high demand for developing easy and non-destructive biomonitoring tools. In a recent paper published in Trends in Analytical ...
    • A novel use of the leukocyte coping capacity assay to assess the immunomodulatory effects of organohalogenated contaminants in avian wildlife 

      Hansen, Elisabeth; Huber, Nikolaus; Bustnes, Jan O.; Herzke, Dorte; Bårdsen, Bård-Jørgen; Eulaers, Igor; Johnsen, Trond V.; Bourgeon, Sophie (Peer reviewed; Journal article, 2020)
      Apex predators are characterized by high levels of biomagnifying organohalogenated contaminants (OHCs) which have been found to induce detrimental health effects in wildlife, such as immune system impairment. The leukocyte ...
    • Plasma concentrations of organohalogenated contaminants in white-tailed eagle nestlings – The role of age and diet 

      Løseth, Mari Engvig; Briels, Nathalie; Eulaers, Igor; Nygård, Torgeir; Malarvannan, Govindan; Poma, Giulia; Covaci, Adrian; Herzke, Dorte; Bustnes, Jan Ove; Lepoint, Gilles; Jenssen, Bjørn Munro; Jaspers, Veerle (Journal article; Peer reviewed, 2019)
      Concentrations of organohalogenated contaminants (OHCs) can show significant temporal and spatial variation in the environment and wildlife. Most of the variation is due to changes in use and production, but environmental ...
    • A schematic sampling protocol for contaminant monitoring in raptors 

      Espín, Silvia; Andevski, Jovan; Duke, Guy; Eulaers, Igor; Gomez-Ramirez, Pilar; Hallgrimsson, Gunnar Thor; Helander, Björn; Herzke, Dorte; Jaspers, Veerle; Krone, Oliver; Lourenco, Rui; Maria-Mojica, Pedro; Martínez-López, Emma; Mateo, Rafael; Movalli, Paola; Sanchez-Virosta, Pablo; Shore, Richard F.; Sonne, Christian; van den Brink, Nico W.; van Hattum, B.; Vrezec, Al; Wernham, Chris; García-Fernández, Antonio J. (Peer reviewed; Journal article, 2020)
      Birds of prey, owls and falcons are widely used as sentinel species in raptor biomonitoring programmes. A major current challenge is to facilitate large-scale biomonitoring by coordinating contaminant monitoring activities ...
    • Tracking pan-continental trends in environmental contamination using sentinel raptors—what types of samples should we use?
