    • Genetic changes caused by restocking and hydroelectric dams in demographically bottlenecked brown trout in a transnational subarctic riverine system 

      Klutsch, Cornelya; Maduna, Simo; Polikarpova, Natalia; Forfang, Kristin; Aspholm, Paul Eric; Nyman, Tommi; Eiken, Hans Geir; Amundsen, Per-Arne; Hagen, Snorre (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-29)
      Habitat discontinuity, anthropogenic disturbance, and overharvesting have led to population fragmentation and decline worldwide. Preservation of remaining natural genetic diversity is crucial to avoid continued genetic erosion. Brown trout (<i>Salmo trutta</i> L.) is an ideal model species for studying anthropogenic influences on genetic integrity, as it has experienced significant genetic alterations ...

    • Temporal analysis shows relaxed genetic erosion following improved stocking practices in a subarctic transnational brown trout population 

      Klutsch, Cornelya; Maduna, Simo; Polikarpova, Natalia; Forfang, Kristin; Beddari, Benedicte Lissner; Gjelland, Karl Øystein; Aspholm, Paul Eric; Amundsen, Per-Arne; Hagen, Snorre (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-30)
      Maintaining standing genetic variation is a challenge in human-dominated landscapes. We used genetic (i.e., 16 short tandem repeats) and morphological (i.e., length and weight) measurements of 593 contemporary and historical brown trout (Salmo trutta) samples to study fine-scale and short-term impacts of different management practices. These had changed from traditional breeding practices, using the ...
