• Fitness in male black grouse (Tetrao tetrix) : effects of life histories and sexual selection on male lifetime mating success 

  Kervinen, Matti (University of Jyväskylä, 2013)

• Variation in parasite resistance of Arctic charr, Salvelinus alpinus, between and within sympatric morphs 

  Karvonen, Anssi; Beck, Samantha V.; Skúlason, Skúli; Kristjánsson, Bjarni K.; Leblanc, Camille A. (Wiley-Blackwell, 2021)

  Genetic variation in resistance against parasite infections is a predominant feature in host–parasite systems. However, mechanisms maintaining genetic polymorphism in resistance in natural host populations are generally ...

• The maintenance of sexually antagonistic variation in reproductive success by negative frequency-dependence in the bank vole (Myodes glareolus) 

  Martiskainen, Henna (2011)

  Natural selection theory predicts low variance in traits closely related to reproductive success, since the most fit trait value should replace all the others. However, a considerable amount of variation is found in ...

• Trophic niche of arctic charr (Salvelinus alpinus) coexisting with lake trout (Salvelinus namaycush) and european whitefish (Coregonus lavaretus) in two divergent subarctic lakes 

  Nieminen, Petri (2012)

• Resource Partitioning in Food, Space and Time between Arctic Charr (Salvelinus alpinus), Brown Trout (Salmo trutta) and European Whitefish (Coregonus lavaretus) at the Southern Edge of Their Continuous Coexistence 

  Jensen, Hallvard; Kiljunen, Mikko; Knudsen, Rune; Amundsen, Per-Arne (Public Library of Science, 2017)

  Arctic charr and European whitefish are considered to be strong competitors in lakes, with the latter usually being the superior species. However, high niche plasticity and lake morphometry may suggestively facilitate ...
