    • Genetic population structure and variation at phenology‐related loci in anadromous Arctic char (Salvelinus alpinus) 

      Madsen, Rikke; Jacobsen, Magnus W; O´Malley, Kathleen G; Nygaard, Rasmus; Præbel, Kim; Jonsson, Bjarni; Pujolar, Jose M; Fraser, Dylan J; Bernatchez, Louis; Hansen, Michael M (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-03)
      The Arctic will be especially affected by climate change, resulting in altered seasonal timing. Anadromous Arctic char (<i>Salvelinus alpinus</i>) is strongly influenced by sea surface temperature (SST) delimiting time periods available for foraging in the sea. Recent studies of salmonid species have shown variation at phenology‐related loci associated with timing of migration and spawning. We ...

    • Migration patterns of Greenland halibut in the North Atlantic revealed by a compiled mark-recapture dataset 

      Vihtakari, Mikko; Elvarsson, Bjarki Pór; Treble, Margaret; Nogueira, Adriana; Hedges, Kevin; Hussey, Nigel E.; Wheeland, Laura; Roy, Denis; Ofstad, Lise Helen; Hallfredsson, Elvar Halldor; Barkley, Amanda; Estevez-Barcia, Daniel; Nygaard, Rasmus; Healey, Brian; Steingrund, Petur; Johansen, Torild; Albert, Ole Thomas; Boje, Jesper (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-18)
      Marine fisheries are often allocated to stocks that reflect pragmatic considerations and may not represent the species’ spatial population structure, increasing the risk of mismanagement and unsustainable harvesting. Here we compile mark–recapture data collected across the North Atlantic to gain insight into the spatial population structure of Greenland halibut (Reinhardtius hippoglossoides), an ...
