    • DNA and scale reading to identify repeat spawning in Atlantic salmon: Unique insights into patterns of iteroparity 

      Kaland, Håvard; Harvey, Alison C.; Skaala, Øystein; Wennevik, Vidar; Besnier, Francois; Andersen-Fjeldheim, Per Tommy; Knutar, Sofie; Andersen-Fjeldheim, Kaja Christine; Glover, Kevin Alan (Journal article; Peer reviewed, 2023)
      Iteroparity represents an important but often overlooked component of life history in anadromous Atlantic salmon. Here, we combined individual DNA profiling and scale reading to identify repeat spawners among ~8000 adult ...

    • Large-effect loci mediate rapid adaptation of salmon body size after river regulation 

      Jensen, Arne Johan; Hagen, Ingerid Julie; Czorlich, Yann; Bolstad, Geir Hysing; Bremset, Gunnbjørn; Finstad, Bengt; Hindar, Kjetil; Skaala, Øystein; Karlsson, Sten (Peer reviewed; Journal article, 2022)
      Understanding the potential of natural populations to adapt to altered environments is becoming increasingly relevant in evolutionary research. Currently, our understanding of adaptation to human alteration of the environment ...

    • Timing is everything: Survival of Atlantic salmon Salmo salar postsmolts during events of high salmon lice densities 

      Bøhn, Thomas; Gjelland, Karl Øystein; Serra Llinares, Rosa Maria; Finstad, Bengt; Primicerio, Raul; Nilsen, Rune; Karlsen, Ørjan; Sandvik, Anne Dagrun; Skilbrei, Ove Tommy; Elvik, Kristine Marit Schrøder; Skaala, Øystein; Bjørn, Pål Arne (Peer reviewed; Journal article, 2020)
      Atlantic salmon in aquaculture act as reservoir hosts and vectors of parasites like salmon lice and this parasite is shown to harm wild salmonid populations. In this study, n = 29,817 tagged Atlantic salmon were studied ...
