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 ... -
Mercury and amino acid content relations in northern pike (Esox lucius) in subarctic lakes along a climate-productivity gradient
Kozak, Natalia; Kahilainen, Kimmo Kalevi; Pakkanen, Hannu K.; Hayden, Brian; Østbye, Kjartan; Taipale, Sami J. (Peer reviewed; Journal article, 2023)Mercury is a highly toxic element for consumers, but its relation to amino acids and physiology of wild fish is not well known. The main aim of this study was to evaluate how total mercury content (THg) of northern pike ... -
Multitrophic biodiversity patterns and environmental descriptors of sub-Arctic lakes in northern Europe
Lau, Danny C.P.; Christoffersen, Kirsten S.; Erkinaro, Jaakko; Hayden, Brian; Heino, Jani; Hellsten, Seppo; Holmgren, Kerstin; Kahilainen, Kimmo Kalevi; Kahlert, Maria; Karjalainen, Satu Maaria; Karlsson, Jan; Forsström, Laura; Lento, Jennifer; Mjelde, Marit; Ruuhijärvi, Jukka; Sandøy, Steinar; Schartau, Ann Kristin; Svenning, Martin; Vrede, Tobias; Goedkoop, Willem (Peer reviewed; Journal article, 2020)1. Arctic and sub-Arctic lakes in northern Europe are increasingly threatened by climate change, which can affect their biodiversity directly by shifting thermal and hydrological regimes, and indirectly by altering landscape ... -

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 ... -
