      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 ...

    • 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 ...
