    • Circumpolar patterns of Arctic freshwater fish biodiversity: A baseline for monitoring 

      Laske, Sarah M.; Amundsen, Per-Arne; Christoffersen, Kirsten Seestern; Erkinaro, Jaakko; Guðbergsson, Guðni; Hayden, Brian; Heino, Jani; Holmgren, Kerstin; Kahilainen, Kimmo Kalevi; Lento, Jennifer; Orell, Panu; Östergren, Jan; Power, Michael; Rafikov, Ruslan; Romakkaniemi, Atso; Svenning, Martin; Swanson, Heidi; Whitman, Matthew; Zimmerman, Christian E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-01)
      Climate change, biological invasions, and anthropogenic disturbance pose a threat to the biodiversity and function of Arctic freshwater ecosystems. Understanding potential changes in fish species distribution and richness is necessary, given the great importance of fish to the function of freshwater ecosystems and as a resource to humans. However, information gaps limit large‐scale studies and our ...

    • Expected Climate Change in the High Arctic—Good or Bad for Arctic Charr? 

      Svenning, Martin; Bjørvik, Eigil T.; Godiksen, Jane Aanestad; Hammar, Johan; Kohler, Jack; Borgstrøm, Reidar; Yoccoz, Nigel Gilles (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-23)
      Lakes in the High Arctic are characterized by their low water temperature, long-term ice cover, low levels of nutrients, and low biodiversity. These conditions mean that minor climatic changes may be of great importance to Arctic freshwater organisms, including fish, by influencing vital life history parameters such as individual growth rates. In this study, Arctic charr sampled from two Svalbard ...

    • Life history genomic regions explain differences in Atlantic salmon marine diet specialization 

      Aykanat, Tutku; Rasmussen, Martin; Ozerov, Mikhail; Niemelä, Eero; Paulin, Lars; Vähä, Juha-Pekka; Hindar, Kjetil; Wennevik, Vidar; Pedersen, Torstein; Svenning, Martin; Primmer, Craig R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-16)
      1. Animals employ various foraging strategies along their ontogeny to acquire energy, and with varying degree of efficiencies, to support growth, maturation and subsequent reproduction events. Individuals that can efficiently acquire energy early are more likely to mature at an earlier age, as a result of faster energy gain which can fuel maturation and reproduction.<p><p> 2. We aimed to test the ...

    • Sjørøye – økologisk og/eller genetisk segregering? 

      Svenning, Martin; Præbel, Kim; Kanstad Hanssen, Øyvind; Falkegård, Morten (Research report; Forskningsrapport, 2013)
      Nedgang i fangstene av sjørøye har ført til behov for regulering av fisket, og i revideringen av elveforskriftene for fisket etter anadrom fisk de siste årene har det vært iverksatt innstramminger i fisket etter etter sjørøye. I slike sammenhenger er kunnskap om det genetiske forholdet mellom sjøvandrende og stasjonær røye innenfor et vassdrag en helt sentral og nødvendig kunnskapsbrikke for definering ...

    • Temporally stable population-specific differences in run timing of one-sea-winter Atlantic salmon returning to a large river system 

      Vähä, Juha-Pekka; Erkinaro, Jaakko; Niemelä, Eero; Primmer, Craig R.; Saloniemi, Irma; Johansen, Morten; Svenning, Martin; Brørs, Sturla (Journal article; Tidsskriftartikkel; Peer reviewed, 2010-12-06)
      The understanding of migration patterns can significantly contribute to conservation and management. The spawning migrations of Atlantic salmon (<i>Salmo salar</i>) cover thousands of kilometers from the feeding areas at sea to their natal rivers to reproduce. Migrating salmon are exposed to intensive harvest, but little is known of the population‐specific differences in migration behavior. In this ...
