    • A brain and a head for a different habitat: Size variation in four morphs of Arctic charr (Salvelinus alpinus (L.)) in a deep oligotrophic lake 

      Tamayo, Ana-Maria Peris; Devineau, Olivier; Præbel, Kim; Kahilainen, Kimmo Kalevi; Østbye, Kjartan (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-25)
      Adaptive radiation is the diversification of species to different ecological niches and has repeatedly occurred in different salmonid fish of postglacial lakes. In Lake Tinnsjøen, one of the largest and deepest lakes in Norway, the salmonid fish, Arctic charr (<i>Salvelinus alpinus</i> (L.)), has likely radiated within 9,700 years after deglaciation into ecologically and genetically segregated ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-05)
      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 isolation. The assumed precondition for rapid local adaptation is diversifying natural selection, but random genetic drift could also be a major driver of this process. We used 27 ...

    • Fishes in a changing world: learning from the past to promote sustainability of fish populations 

      Gordon, Timothy A.C.; Harding, Harry R.; Clever, Friederike K.; Davidson, Isla Keesje; Davison, William; Montgomery, Daniel W.; Weatherhead, Rebekah C.; Windsor, Fredric M.; Armstrong, John D.; Bardonnet, Agnès; Bergman, Eva; Britton, John Robert; Côté, Isabelle M.; D'agostino, Daniele; Greenberg, Larry; Harborne, Alastair R.; Kahilainen, Kimmo Kalevi; Metcalfe, Neil B.; Mills, Suzanne C.; Milner, Nigel J.; Mittermayer, Felix H.; Montorio, Lucie; Nedelec, Sophie L.; Prokkola, Jenni M.; Rutterford, Louise A.; Salvanes, Anne Gro Vea; Simpson, Stephen D.; Vainikka, Anssi; Pinnegar, John Keith; Santos, Eduarda M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-14)
      Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, energy and goods are compromising fish populations through a variety of mechanisms, including overfishing, habitat degradation and declines in water quality. The important ...

    • Simulated eutrophication and browning alters zooplankton nutritional quality and determines juvenile fish growth and survival 

      Taipale, Sami Johan; Kahilainen, Kimmo Kalevi; Holtgrieve, Gordon William; Peltomaa, Elina Talvikki (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-06)
      The first few months of life is the most vulnerable period for fish and their optimal hatching time with zooplankton prey is favored by natural selection. Traditionally, however, prey abundance (i.e., zooplankton density) has been considered important, whereas prey nutritional composition has been largely neglected in natural settings. High‐quality zooplankton, rich in both essential amino acids ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-30)
      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 of general theoretical concepts and tools to specific ecological systems remains a challenge. Here we apply modeling tools to better understand adaptive divergence of whitefish ...
