    • Energy efficiency of respiration in mature and newborn reindeer 

      Solberg, Simon Birger Byremo; Kjelstrup, Signe; Magnanelli, Elisa; Kizilova, Nataliya; Barroso, Iratxe Lorea Casado; Acquarone, Mario; Folkow, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-25)
      Reindeer (<i>Rangifer tarandus</i>) have evolved elaborate nasal turbinate structures that are perfused via a complex vascular network. These are subject to thermoregulatory control, shifting between heat conservation and dissipation, according to the animal’s needs. The three-dimensional design of the turbinate structures is essential in the sense that they determine the efficiency with which heat ...

    • The Nasal Geometry of the Reindeer Gives Energy-Efficient Respiration 

      Magnanelli, Elisa; Wilhelmsen, Øivind; Acquarone, Mario; Folkow, Lars; Kjelstrup, Signe (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-14)
      Reindeer in the arctic region live under very harsh conditions and may face temperatures below 233 K. Therefore, efficient conservation of body heat and water is important for their survival. Alongside their insulating fur, the reindeer nasal mechanism for heat and mass exchange during respiration plays a fundamental role. We present a dynamic model to describe the heat and mass transport that takes ...
