    • 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 ...

    • From clear lakes to murky waters – tracing the functional response of high-latitude lake communities to concurrent ‘greening’ and ‘browning’ 

      Hayden, B.; Harrod, C.; Thomas, S.M.; Eloranta, Antti; Myllykangas, J.‐P.; Siwertsson, Anna; Præbel, Kim; Knudsen, Rune; Amundsen, Per-Arne; Kahilainen, Kimmo Kalevi (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-21)
      Climate change and the intensification of land use practices are causing widespread eutrophication of subarctic lakes. The implications of this rapid change for lake ecosystem function remain poorly understood. To assess how freshwater communities respond to such profound changes in their habitat and resource availability, we conducted a space‐for‐time analysis of food‐web structure in 30 lakes ...

    • Improved Environmental Status: 50 Years of Declining Fish Mercury Levels in Boreal and Subarctic Fennoscandia 

      Braaten, Hans Fredrik Veiteberg; Åkerblom, Staffan; Kahilainen, Kimmo Kalevi; Rask, Martti; Vuorenmaa, Jussi; Mannio, Jaakko; Malinen, Tommi; Lydersen, Espen; Poste, Amanda; Amundsen, Per-Arne; Kashulin, Nikolai; Kashulina, Tatiana; Terentjev, Petr; Christensen, Guttorm; de Wit, Heleen (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-14)
      Temporally (1965–2015) and spatially (55°–70°N) extensive records of total mercury (Hg) in freshwater fish showed consistent declines in boreal and subarctic Fennoscandia. The database contains 54 560 fish entries (n: pike > perch ≫ brown trout > roach ≈ Arctic charr) from 3132 lakes across Sweden, Finland, Norway, and Russian Murmansk area. 74% of the lakes did not meet the 0.5 ppm limit to protect ...

    • Resource polymorphism in European whitefish: Analysis of fatty acid profiles provides more detailed evidence than traditional methods alone 

      Thomas, Stephen M; Kainz, Martin J.; Amundsen, Per-Arne; Hayden, Brian; Taipale, Sami Johan; Kahilainen, Kimmo Kalevi (Journal article; Peer reviewed, 2019-08-20)
      Resource polymorphism—whereby ancestral generalist populations give rise to several specialised morphs along a resource gradient—is common where species colonise newly formed ecosystems. This phenomenon is particularly well documented in freshwater fish populations inhabiting postglacial lakes formed at the end of the last ice age.<br> However, knowledge on how such differential exploitation of ...

    • A way forward with eco evo devo: an extended theory of resource polymorphism with postglacial fishes as model systems 

      Skulason, Skuli; Parsons, Kevin J; Svanback, Richard; Räsänen, Katja; Ferguson, Moira M; Adams, Colin Ean; Amundsen, Per-Arne; Bartels, Pia; Bean, Colin W.; Boughman, Janette W.; Englund, Göran; Gudbrandsson, Johannes; Hooker, Oliver E.; Hudson, Alan G; Kahilainen, Kimmo Kalevi; Knudsen, Rune; Kristjánsson, Bjarni Kr.; Leblanc, Camille A-L; Jonsson, Zophonias; Ohlund, Gunnar; Smith, Carl; Snorrason, Sigurdur S (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-19)
      A major goal of evolutionary science is to understand how biological diversity is generated and altered. Despite considerable advances, we still have limited insight into how phenotypic variation arises and is sorted by natural selection. Here we argue that an integrated view, which merges ecology, evolution and developmental biology (eco evo devo) on an equal footing, is needed to understand the ...
