    • Body mass is associated with hibernation length, body temperature, and heart rate in free-ranging brown bears 

      Evans, Alina; Fuchs, Boris; Singh, Navinder; Thiel, Alexandra; Giroud, Sylvain; Blanc, Stephane; Laske, Timothy G.; Frobert, Ole; Friebe, Andrea; Swenson, Jon; Arnemo, Jon Martin (Peer reviewed; Journal article, 2023)
      Background Despite centuries of research, debate remains on the scaling of metabolic rate to mass especially for intraspecific cases. The high variation of body mass within brown bears presents a unique opportunity to ...

    • The cost of research: Lasting effects of capture, surgery and muscle biopsy on brown bear (Ursus arctos) movement and physiology 

      Thiel, Alexandra; Hertel, Anne Gabriela; Giroud, Sylvain; Friebe, Andrea; Fuchs, Boris; Kindberg, Jonas; Græsli, Anne Randi; Arnemo, Jon Martin; Evans, Alina (Peer reviewed; Journal article, 2023)
      Animal models are a key component of translational medicine, helping transfer scientific findings into practical applications for human health. A fundamental principle of research ethics involves weighing the benefits of ...

    • Extrinsic and intrinsic factors drive the timing of gestation and reproductive success of Scandinavian brown bears 

      Lemière, Lucie; Thiel, Alexandra; Fuchs, Boris; Gilot-Fromont, Emmanuelle; Hertel, Anne G.; Friebe, Andrea; Kindberg, Jonas; Støen, Ole-Gunnar; Arnemo, Jon Martin; Evans, Alina L. (Peer reviewed; Journal article, 2022)
      Climate change is altering the reproductive phenology of many organisms, but the factors that influence the timing of gestation in ursids are still poorly understood. Higher temperatures in spring are already causing an ...

    • Factors affecting date of implantation, parturition, and den entry estimated from activity and body temperature in free-ranging brown bears 

      Friebe, Andrea; Evans, Alina L.; Arnemo, Jon Martin; Blanc, Stephane; Brunberg, Sven; Fleissner, Günther; Swenson, Jon E.; Zedrosser, Andreas (Journal article; Peer reviewed, 2014)
      Knowledge of factors influencing the timing of reproduction is important for animal conservation and management. Brown bears (Ursus arctos) are able to vary the birth date of their cubs in response to their fat stores, but ...

    • Physiological reactions to capture in hibernating brown bears 

      Evans, Alina L.; Singh, Navinder J.; Fuchs, Boris; Blanc, Stephane; Friebe, Andrea; Laske, Timothy G.; Frobert, Ole; Swenson, Jon E.; Arnemo, Jon Martin (Journal article; Peer reviewed, 2016)
      Human disturbance can affect animal life history and even population dynamics. However, the consequences of these disturbances are difficult to measure. This is especially true for hibernating animals, which are highly ...

    • Physiological reactions to capture in hibernating brown bears 

      Evans, Alina L.; Singh, Navinder J.; Fuchs, Boris; Blanc, Stéphane; Friebe, Andrea; Laske, Timothy; Fröbert, Ole; Swenson, Jon; Arnemo, Jon Martin (Peer reviewed; Journal article, 2016)

    • Seasonality in Biological Rhythms in Scandinavian brown Bears 

      Thiel, Alexandra; Giroud, Sylvain; Hertel, Anne Gabriela; Friebe, Andrea; Devineau, Olivier; Fuchs, Boris; Blanc, Stephane; Støen, Ole-Gunnar; Laske, Timothy G.; Arnemo, Jon Martin; Evans, Alina (Peer reviewed; Journal article, 2022)
      Biological rhythms, such as rhythms in activity and body temperature, are usually highly synchronized and entrained by environmental conditions, such as photoperiod. However, how the expression of these rhythms changes ...
