    • The role of gill raker number variability in adaptive radiation of coregonid fish 

      Kahilainen, Kimmo; Siwertsson, Anna; Gjelland, Karl Øystein; Knudsen, Rune; Bøhn, Thomas; Amundsen, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2010-07-27)
      Gill raker divergence is a general pattern in adaptive radiations of postglacial fish, but few studies have addressed the adaptive significance of this morphological trait in foraging and eco-evolutionary interactions among predator and prey. Here, a set of subarctic lakes along a diversifying gradient of coregonids was used as the natural setting to explore correlations between gill raker numbers ...

    • Sympatric diversification as influenced by ecological opportunity and historical contingency in a young species lineage of whitefish 

      Siwertsson, Anna; Knudsen, Rune; Kahilainen, Kimmo; Præbel, Kim; Primicerio, Raul; Amundsen, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)
      In adaptive radiations, ecological opportunity (i.e. niche availability) is considered to be an important driver to increase phenotypic variation, but diversity may also be constrained by historical factors related to colonization events. How do ecological opportunity and post-glacial colonization history affect the phenotypic diversity in a young species lineage? We quantified phenotypic diversity ...
