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 (Peer reviewed; Journal article, 2020)Reindeer (Rangifer tarandus) 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 ... -
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 (Peer reviewed; Journal article, 2023)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 ... -
The Nasal Geometry of the Reindeer Gives Energy-Efficient Respiration
Magnanelli, Elisa; Wilhelmsen, Øivind; Acquarone, Mario; Folkow, Lars; Kjelstrup, Signe (Journal article; Peer reviewed, 2016)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 ... -
Thermal modeling of the respiratory turbinates in arctic and subtropical seals
Flekkøy, Eirik Grude; Folkow, Lars; Kjelstrup, Signe; Mason, Matthew J.; Wilhelmsen, Øivind (Peer reviewed; Journal article, 2023)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 ...
