    • Structure and function of respiratory turbinates in phocid seals 

      Mason, Matthew J.; Wenger, Lea M.D.; Hammer, Øyvind; Blix, Arnoldus S (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-13)
      In terrestrial mammals, the respiratory turbinate bones within the nasal cavity are employed to conserve heat and water. In order to investigate whether environmental temperature affects respiratory turbinate structure in phocids, we used micro-computed tomography to compare maxilloturbinate bone morphology in polar seals, grey seals and monk seals. The maxilloturbinates of polar seals have much ...

    • Structure-function relationships in the nasal cavity of Arctic and subtropical seals 

      Cheon, Hyejeong; Kjelstrup, Signe; Kizilova, Nataliya; Flekkøy, Eirik Grude; Mason, Matthew J.; Folkow, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-14)
      The heating and moistening of inhaled air, and the cooling and moisture removal from exhaled air, are crucial for the survival of animals under severe environmental conditions. Arctic mammals have evolved specific adaptive mechanisms to retain warmth and water and restrict heat loss during breathing. Here, the role of the porous turbinates of the nasal cavities of Arctic and subtropical seals is ...

    • Thermal modeling of the respiratory turbinates in arctic and subtropical seals 

      Flekkøy, Eirik Grude; Folkow, Lars; Kjelstrup, Signe; Mason, Matthew J.; Wilhelmsen, Øivind (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-06)
      Mammals possess complex structures in their nasal cavities known as respiratory turbinate bones, which help the animal to conserve body heat and water during respiratory gas exchange. We considered the function of the maxilloturbinates of two species of seals, one arctic (<i>Erignathus barbatus</i>), one subtropical (<i>Monachus monachus</i>). By means of a thermo-hydrodynamic model that describes ...
