    • Life history of Leptagonus decagonus (Atlantic poacher) in Svalbard waters 

      Heggland, Kristin; Ottesen, Camilla; Berge, Jørgen (Conference object; Konferansebidrag, 2012-04)
      <p>The demersal fish species <i>Leptagonus decagonus</i> (Atlantic poacher) is a commonly encountered species on the continental shelf in the Barents Sea and around Svalbard, but little is known about the life-history and population traits of the species in Svalbard waters. It is therefore important to investigate this species to understand its importance in the ecosystem. <p>A total of 80 specimens ...

    • Pelagic food-webs in a changing Arctic: a trait-based perspective suggests a mode of resilience 

      Renaud, Paul Eric; Daase, Malin; Banas, Neil; Gabrielsen, Tove M.; Søreide, Janne; Varpe, Øystein; Cottier, Finlo Robert; Falk-Petersen, Stig; Halsband, Claudia; Vogedes, Daniel Ludwig; Heggland, Kristin; Berge, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-27)
