    • Gene flow from domesticated escapes alters thelife history of wild Atlantic salmon 

      Bolstad, Geir Hysing; Hindar, Kjetil; Robertsen, Grethe; Jonsson, Bror; Sægrov, Harald; Diserud, Ola Håvard; Fiske, Peder; Jensen, Arne Johan; Urdal, Kurt; Næsje, Tor; Barlaup, Bjørn Torgeir; Florø-Larsen, Bjørn; Lo, Håvard; Niemela, Eero; Karlsson, Sten (Journal article, 2017)
      Interbreeding between domesticated and wild animals occurs in several species. This gene flow has long been anticipated to induce genetic changes in life-history traits of wild populations, thereby influencing population ...

    • Introgression from farmed escapees affects the full life cycle of wild Atlantic salmon 

      Bolstad, Geir Hysing; Karlsson, Sten; Hagen, Ingerid Julie; Fiske, Peder; Urdal, Kurt; Sægrov, Harald; Florø-Larsen, Bjørn; Sollien, Vegard Pedersen; Østborg, Gunnel Marie; Diserud, Ola Håvard; Jensen, Arne Johan; Hindar, Kjetil (Peer reviewed; Journal article, 2021)
      After a half a century of salmon farming, we have yet to understand how the influx of genes from farmed escapees affects the full life history of Atlantic salmon (Salmo salar L.) in the wild. Using scale samples of over ...

    • Iteroparity and its contribution to life-history variation in Atlantic salmon 

      Persson, Lo; Raunsgard, Astrid; Thorstad, Eva Bonsak; Østborg, Gunnel Marie; Urdal, Kurt; Sægrov, Harald; Ugedal, Ola; Hindar, Kjetil; Karlsson, Sten; Fiske, Peder; Bolstad, Geir Hysing (Peer reviewed; Journal article, 2023)
      Evolution of iteroparity is shaped by the trade-off between current and future reproduction.We studied variation in iteroparity among 205 050 individual Atlantic salmon caught in 179 rivers spanning 14◦ of latitude. The ...

    • Natural and anthropogenic drivers of escaped farmed salmon occurrence and introgression into wild Norwegian Atlantic salmon populations 

      Diserud, Ola Håvard; Fiske, Peder; Karlsson, Sten; Glover, Kevin Alan; Næsje, Tor; Aronsen, Tonje; Bakke, Gunnar O; Barlaup, Bjørn Torgeir; Erkinaro, J.; Florø-Larsen, Bjørn; Foldvik, Anders; Heino, Mikko Petteri; Kanstad-Hanssen, Øyvind; Lo, Håvard; Lund, Roar Asbjørn; Muladal, R.; Niemela, E.; Økland, Finn; Østborg, Gunnel Marie; Otterå, Håkon Magne; Skaala, Øystein; Skoglund, Helge; Solberg, Ingrid; Solberg, Monica Favnebøe; Sollien, Vegard Pedersen; Sægrov, Harald; Urdal, Kurt; Wennevik, Vidar; Hindar, Kjetil (Peer reviewed; Journal article, 2022)
      Marine aquaculture of Atlantic salmon (Salmo salar) is a relatively new industry where breeding programs have led to rapid genetic change in the captive populations that were built up alongside conspecific wild individuals. ...
