    • 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; 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 ...

    • Monitoring of the Pasvik-Inari-Pechenga brown bear (Ursus arctos) population in 2019 using hair trap 

      Beddari, Benedicte Lissner; Ogurtsov, Sergey; Magga, Sari; Kangasniemi, Jaru; Fløystad, Ida; Søvik, Inger; Randa, Rolf; Ollila, Leif E.; Lindgren, Vetle; Bakke, Beate Banken; Beddari, Vilde; Polikarpova, Natalia; Ollila, Tuomo; Hagen, Snorre; Eiken, Hans Geir (NIBIO Rapport;6(61) 2020, Research report, 2020-04)
      Siden 2005 har populasjonen av grenseoverskridene brunbjørn (Ursus arctos) i Trilateral Park Pasvik-Inari-Pechenga (Norge-Finland-Russland) blitt overvåket ved å bruke genetiske analyser av hår og ekskrement-prøver samlet ...

    • Monitoring of the Pasvik-Inari-Pechenga brown bear population in 2007 and 2011 using hair-trapping 

      Kopatz, Alexander; Eiken, Hans Geir; Aspholm, Paul Eric; Tobiassen, Camilla; Bakke, Beate Banken; Schregel, Julia; Ollila, Tuomo; Makarova, Olga; Polikarpova, Natalia; Chizhov, Vladimir; Hagen, Snorre (Bioforsk rapport;6(148) 2011, Research report, 2011-12-22)
      The trans-border brown bear population of Pasvik-Inari-Pechenga (Norway-Finland-Russia) has been monitored using genetic analyses of feces collection since 2005. In addition in 2007, hair traps were systematically placed ...

    • Monitoring of the Pasvik-Inari-Pechenga brown bear population in 2015 using hair-trapping 

      Aarnes, Siv; Kopatz, Alexander; Eiken, Hans Geir; Schregel, Julia; Aspholm, Paul Eric; Ollila, Tuomo; Makarova, Olga; Polikarpova, Natalia; Chizhov, Vladimir; Ogurtcov, Sergey; Hagen, Snorre (NIBIO Rapport;1(69), Research report, 2015)
      The trans-border brown bear population of Pasvik-Inari-Pechenga (Norway-Finland-Russia) has been monitored using genetic analyses of feces collection since 2005. In addition, in 2007 and 2011, hair traps were systematically ...

    • Studying phenological phenomena in subarctic biomes with international school pupils as citizen scientists 

      Klutsch, Cornelya; Aspholm, Paul Eric; Polikarpova, Natalia; Veisblium, Olga; Bjørn, Tor-Arne; Wikan, Anne; Gonzalez, Victoria; Hagen, Snorre B. (Peer reviewed; Journal article, 2020-12-30)
      Citizen science can facilitate in‐depth learning for pupils and students, contribute to scientific research, and permit civic participation. Here, we describe the development of the transnational school‐based citizen science ...

    • 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 (Peer reviewed; Journal article, 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 ...
