    • 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 ...

    • Assessing the reproductive biology of the Greenland shark (Somniosus microcephalus) 

      Nielsen, Julius; Hedeholm, Rasmus B.; Lynghammar, Arve; McClusky, Leon Mendel; Berland, Bjørn; Steffensen, John Fleng; Christiansen, Jørgen Schou (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-07)
      The Greenland shark (<i>Somniosus microcephalus</i>, Squaliformes: Somniosidae) is a long-lived Arctic top predator, which in combination with the high historical and modern fishing pressures, has made it subject to increased scientific focus in recent years. Key aspects of reproduction are not well known as exemplified by sparse and contradictory information e.g. on birth size and number of pups ...

    • Boreal marine fauna from the Barents sea disperse to Arctic Northeast Greenland 

      Andrews, Adam; Christiansen, Jørgen Schou; Bhat, Shripathi; Lynghammar, Arve; Westgaard, Jon-Ivar; Pampoulie, Christophe; Præbel, Kim (Journal article; Peer reviewed, 2019-04-09)
      As a result of ocean warming, the species composition of the Arctic seas has begun to shift in a boreal direction. one ecosystem prone to fauna shifts is the Northeast Greenland shelf. the dispersal route taken by boreal fauna to this area is, however, not known. This knowledge is essential to predict to what extent boreal biota will colonise Arctic habitats. Using population genetics, we show that ...
