    • Advancing research for the management of long-lived species: A case study on the Greenland Shark 

      Edwards, Jena E.; Hiltz, Elizabeth; Broell, Franziska; Bushnell, Peter G.; Campana, Steven E.; Christiansen, Jørgen Schou; Devine, Brynn M.; Gallant, Jeffrey J.; Hedges, Kevin J.; MacNeil, M. Aaron; McMeans, Bailey C.; Nielsen, Julius; Præbel, Kim; Skomal, Gregory B.; Steffensen, John Fleng; Walter, Ryan P.; Watanabe, Yuuki Y.; VanderZwaag, David L.; Hussey, Nigel E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-02)
      Long-lived species share life history traits such as slow growth, late maturity, and low fecundity, which lead to slow recovery rates and increase a population’s vulnerability to disturbance. The Greenland shark (Somniosus microcephalus) has recently been recognized as the world’s longest-lived vertebrate, but many questions regarding its biology, physiology, and ecology remain unanswered. Here we ...

    • Greenland Shark (Somniosus microcephalus) stomach contents and stable isotope values reveal an ontogenetic dietary shift 

      Nielsen, Julius; Christiansen, Jørgen Schou; Grønkjær, Peter; Bushnell, Peter G.; Steffensen, John Fleng; Kiilerich, Helene O.; Præbel, Kim; Hedeholm, Rasmus (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-04)
      Current knowledge on the feeding ecology of the Greenland shark (<i>Somniosus microcephalus</i>), a potential top predator in arctic marine ecosystems, is based on small sample sizes as well as narrow size ranges of sharks. Therefore, potential size-related feeding patterns remain poorly documented. Using stomach content data (<i>N</i> = 88) and stable isotope values of white muscle tissue (<i>N</i> ...
