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. (Peer reviewed; Journal article, 2019)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 ... -
Contrasting patterns in trophic niche evolution of polymorphic Arctic charr populations in two subarctic Norwegian lakes
Moccetti, Paolo Maria; Siwertsson, Anna; Kjær, Runar; Amundsen, Per-Arne; Præbel, Kim; Tamayo, Ana-Maria Peris; Power, Michael; Knudsen, Rune (Peer reviewed; Journal article, 2019-05-15)Parallelism in trophic niches of polymorphic populations of Arctic charr was investigated in two similar subarctic lakes, Tårnvatn and Skøvatn, in northern Norway. Analysis of eleven microsatellite loci confirmed, respectively, ... -
Diversifying selection drives parallel evolution of gill raker number and body size along the speciation continuum of European whitefish
Häkli, Katja; Østbye, Kjartan; Kahilainen, Kimmo Kalevi; Amundsen, Per-Arne; Præbel, Kim (Peer reviewed; Journal article, 2018)Adaptive radiation is the evolution of ecological and phenotypical diversity. It arises via ecological opportunity that promotes the exploration of underutilized or novel niches mediating specialization and reproductive ... -
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 (Peer reviewed; Journal article, 2019)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 ... -
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 (Peer reviewed; Journal article, 2019)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 ... -
Using mathematical modelling to investigate the adaptive divergence of whitefish in Fennoscandia
Thibert-Plante, Xavier; Præbel, Kim; Østbye, Kjartan; Kahilainen, Kimmo Kalevi; Amundsen, Per-Arne; Gavrilets, Sergey (Peer reviewed; Journal article, 2020)Modern speciation theory has greatly benefited from a variety of simple mathematical models focusing on the conditions and patterns of speciation and diversification in the presence of gene flow. Unfortunately the application ...
