    • Carbon, Nitrogen and Sulphur isotopic fractionation in captive juvenile hooded seal (Cystophora cristata): application for diet analysis 

      Pinzone, Marianna; Acquarone, Mario; Huyghebaert, Loreen; Sturaro, Nicolas; Michel, Loïc N.; Siebert, Ursula; Das, Krishna (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-15)
      <p><i>Rationale</i>: Intrinsic biogeochemical markers, such as stable isotope ratios of carbon, nitrogen and sulphur, are increasingly used to trace the trophic ecology of marine top predators. However, insufficient knowledge of fractionation processes in tissues continues to hamper the use of these markers.</p> <p><i>Methods</i>: We performed a controlled feeding experiment with eight juvenile ...

    • A life after Research? First Release of Harp Seals (Phoca groenlandica) after Temporary Captivity for Scientific Purposes 

      Blanchet, Marie-Anne; Acquarone, Mario; Biuw, Martin; Larsen, Roger B.; Nordøy, Erling Sverre; Folkow, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-08)
      Three wild-caught female harp seals (Pagophilus groenlandicus) from the Greenland Sea stock were brought into temporary captivity in connection with a controlled validation study on energetics. The two pups and one adult were kept in two indoor and outdoor experimental facilities approved by the Norwegian Animal Research Authority. They were trained daily using operant conditioning to participate ...
    • 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 ...
    • Report of the Workshop on Age Estimation in Monodontids 

      Hohn, Aleta A.; Lockyer, Christina; Acquarone, Mario (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      The workshop was a 2-day event organised immediately before the Society for Marine Mammalogy biennial conference in Tampa. NAMMCO funding enabled participation of 4 invited experts and also supported the organization and logistics associated with the workshop. The breadth and depth of the workshop presentations made it clear that most issues concerning monodontid age estimation are not unique. Many ...
