    • Evolution of growth in Gulf of St Lawrence cod? 

      Heino, Mikko; Baulier, Loïc; Boukal, David S.; Dunlop, Erin S.; Eliassen, Sigrunn; Enberg, Katja; Jørgensen, Christian; Varpe, Øystein (Journal article; Peer reviewed, 2008-06-22)
      Fishing is often size selective such that the likelihood of capture increases with body size. It has therefore been postulated that fishing could favour evolution of slower growth because smaller size would reduce exposure ...
    • Evolution of reproduction periods in seasonal environments 

      Sun, Zepeng; Parvinen, Kalle; Heino, Mikko Petteri; Metz, Johan A.J.; de Roos, André M.; Dieckmann, Ulf (Peer reviewed; Journal article, 2020)

    • Evolutionary effects of fishing gear on foraging behavior and life-history traits 

      Claireaux, Marion; Jørgensen, Christian; Enberg, Katja (Journal article; Peer reviewed, 2018)
      Fishing gears are designed to exploit the natural behaviors of fish, and the concern that fishing may cause evolution of behavioral traits has been receiving increasing attention. The first intuitive expectation is that ...
    • An evolutionary explanation of female-biased sexual size dimorphism in North Sea plaice, Pleuronectes platessa L. 

      Mollet, Fabian M.; Enberg, Katja Susanna; Boukal, David; Rijnsdorp, Adriaan D.; Dieckmann, Ulf (Peer reviewed; Journal article, 2023)
      Sexual size dimorphism (SSD) is caused by differences in selection pressures and life-history trade-offs faced by males and females. Proximate causes of SSD may involve sex-specific mortality, energy acquisition, and energy ...

    • Evolutionary predictions for a parasite metapopulation: Modelling salmon louse resistance to pest controls in aquaculture 

      Coates, Andrew; Robinson, Nicholas Andrew; Dempster, Tim; Johnsen, Ingrid Askeland; Phillips, Ben L. (Peer reviewed; Journal article, 2023)
      Pests often evolve resistance to pest controls used in agriculture and aquaculture. The rate of pest adaptation is influenced by the type of control, the selective pressure it imposes, and the gene flow between farms. By ...
    • Evolutionary principles and their practical application 

      Hendry, Andrew P.; Kinnison, Michael T.; Heino, Mikko; Day, Troy; Smith, Thomas B.; Fitt, Gary; Bergstrom, Carl T.; Oakeshott, John; Jørgensen, Peter S.; Zalucki, Myron P.; Gilchrist, George; Southerton, Simon; Sih, Andrew; Strauss, Sharon; Denison, Robert F.; Carroll, Scott P. (Journal article; Peer reviewed, 2011-02-17)
      Evolutionary principles are now routinely incorporated into medicine and agriculture. Examples include the design of treatments that slow the evolution of resistance by weeds, pests, and pathogens, and the design of breeding ...
