    • Haematological and serum biochemical reference values in free-ranging red deer (Cervus elaphus atlanticus) 

      Rosef, Olav; Nystøyl, Håvard L.; Solenes, Tore; Arnemo, Jon Martin (Journal article; Peer reviewed, 2004)
      Analyses of haematological and biochemical constituents were carried out on the Norwegian subspecies of free-ranging red deer (Cervus elaphus atlanticus). All animals were captured from January to March by using a mixture ...
    • High concentrations of lead (Pb) in blood and milk of free-ranging brown bears (Ursus arctos) in Scandinavia 

      Fuchs, Boris; Thiel, Alexandra; Zedrosser, Andreas; Brown, Ludovick; Hydeskov, Helle Bernstorf; Rodushkin, Ilia; Evans, Alina; Boesen, Amanda Høyer; Græsli, Anne Randi; Kindberg, Jonas; Arnemo, Jon Martin (Peer reviewed; Journal article, 2021)
      Exposure to lead (Pb) is a global health problem for both humans and wildlife. Despite a dramatic decline in human Pb exposure following restrictions of leaded gasoline and industry and thereby an overall reduction of Pb ...
    • Insights in the regulation of trimetylamine N-oxide production using a comparative biomimetic approach suggest a metabolic switch in hibernating bears 

      Ebert, Thomas; Painer, Johanna; Bergman, Peter; Qureshi, Abdul Rashid; Giroud, Sylvain; Stalder, Gabrielle; Kublickiene, Karolina; Göritz, Frank; Vetter, Sebastian G.; Bieber, Claudia; Fröbert, Ole; Arnemo, Jon Martin; Zedrosser, Andreas; Redtenbacher, Irene; Shiels, Paul; Johnson, Richard J.; Stenvinkel, Peter (Peer reviewed; Journal article, 2020)
      Experimental studies suggest involvement of trimethylamine N-oxide (TMAO) in the aetiology of cardiometabolic diseases and chronic kidney disease (CKD), in part via metabolism of ingested food. Using a comparative biomimetic ...
    • Landscape of fear or landscape of food? Moose hunting triggers an antipredator response in brown bears 

      Brown, Ludovick; Zedrosser, Andreas; Arnemo, Jon Martin; Fuchs, Boris; Kindberg, Jonas; Pelletier, Fanie (Peer reviewed; Journal article, 2023)
      Hunters can affect the behavior of wildlife by inducing a landscape of fear, selecting individuals with specific traits, or altering resource availability across the landscape. Most research investigating the influence of ...
    • Malnutrition in farmed red deer hinds (Cervus elaphus atlanticus) in Norway 

      Rosef, Olav; Arnemo, Jon Martin (Research report, 2005)
      Malnutrition was studied in farmed red deer. Malnourished animals did not recover from winter energy loss, remained in poor condition throughout the summer, and some died of starvation. Liver analysis of one hind that died ...
    • Metabolic reprogramming involving glycolysis in the hibernating brown bear skeletal muscle 

      Chazarin, Blandine; Storey, Kenneth B.; Ziemianin, Anna; Chanon, Stéphanie; Plumel, M.; Chery, Isabelle; Durand, Christine; Evans, Alina; Arnemo, Jon Martin; Zedrosser, Andreas; Swenson, Jon; Gauquelin-Koch, Guillemette; Simon, Chantal; Blanche, Stephane; Lefai, Etienne; Bertile, Fabrice (Journal article; Peer reviewed, 2019)
      Background In mammals, the hibernating state is characterized by biochemical adjustments, which include metabolic rate depression and a shift in the primary fuel oxidized from carbohydrates to lipids. A number of studies ...
    • Proteolysis inhibition by hibernating bear serum leads to increased protein content in human muscle cells 

      Chanon, Stéphanie; Chazarin, Blandine; Toubhans, Benoit; Durand, Christine; Chery, Isabelle; Robert, Maud; Vieille-Marchiset, Aurélie; Swenson, Jon; Zedrosser, Andreas; Evans, Alina; Brunberg, Sven; Arnemo, Jon Martin; Gauquelin-Koch, Guillemette; Storey, Kenneth B.; Simon, Chantal; Blanc, Stéphane; Bertile, Fabrice; Lefai, Etienne (Journal article; Peer reviewed, 2018)
      Muscle atrophy is one of the main characteristics of human ageing and physical inactivity, with resulting adverse health outcomes. To date, there are still no efficient therapeutic strategies for its prevention and/or ...
    • Retention and loss of PIT tags and surgically implanted devices in the Eurasian beaver 

      Mayer, Martin; Lian, Marianne; Fuchs, Boris; Robstad, Christian; Evans, Alina; Perrin, Kathryn; Greunz, Eva M.; Laske, Timothy G.; Arnemo, Jon Martin; Rosell, Frank Narve (Peer reviewed; Journal article, 2022)
      Background: Passive integrated transponder devices (PIT tags) are a valuable tool for individual identification of animals. Similarly, the surgical implantation of transmitters and bio-loggers can provide useful data on ...
