• Demographic measures of an individual's "pace of life": fecundity rate, lifespan, generation time, or a composite variable? 

      Araya-Ajoy, Yimen; Bolstad, Geir Hysing; Brommer, Jon; Careau, Vincent; Dingemanse, Niels J.; Wright, Jonathan (Journal article; Peer reviewed, 2018)
      Comparative analyses have demonstrated the existence of a ^pace-of-life^ (POL) continuum of life-history strategies, from fastreproducing short-lived species to slow-reproducing long-lived species. This idea has been ...
    • Does lack of evolvability constrain adaptation? If so, on what time scales? 

      Voje, Kjetil L.; Grabowski, Mark; Holstad, Agnes; Porto, Arthur; Tsuboi, Masahito; Bolstad, Geir Hysing (Chapter, 2023)
      The relevance of genetic constraints for evolutionary change beyond microevolutionary timescales is debated. The high evolvability of natural populations predicts rapid adaptation, but evolvability is often found to correlate ...
    • Gene flow from domesticated escapes alters thelife history of wild Atlantic salmon 

      Bolstad, Geir Hysing; Hindar, Kjetil; Robertsen, Grethe; Jonsson, Bror; Sægrov, Harald; Diserud, Ola Håvard; Fiske, Peder; Jensen, Arne Johan; Urdal, Kurt; Næsje, Tor; Barlaup, Bjørn Torgeir; Florø-Larsen, Bjørn; Lo, Håvard; Niemela, Eero; Karlsson, Sten (Journal article, 2017)
      Interbreeding between domesticated and wild animals occurs in several species. This gene flow has long been anticipated to induce genetic changes in life-history traits of wild populations, thereby influencing population ...
    • Intersexual conflict over seed size is stronger in more outcrossed populations of a mixed-mating plant 

      Raunsgard, Astrid; Opedal, Øystein Hjorthol; Ekrem, Runa K; Wright, Jonathan; Bolstad, Geir Hysing; Armbruster, William Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2018)
      Intersexual conflict over maternal resource allocation to offspring can lead to the evolution of imprinted genes with parentof- origin–specific expression. However, the precise mechanism involved in the evolution of ...
    • Introgression from farmed escapees affects the full life cycle of wild Atlantic salmon 

      Bolstad, Geir Hysing; Karlsson, Sten; Hagen, Ingerid Julie; Fiske, Peder; Urdal, Kurt; Sægrov, Harald; Florø-Larsen, Bjørn; Sollien, Vegard Pedersen; Østborg, Gunnel Marie; Diserud, Ola Håvard; Jensen, Arne Johan; Hindar, Kjetil (Peer reviewed; Journal article, 2021)
      After a half a century of salmon farming, we have yet to understand how the influx of genes from farmed escapees affects the full life history of Atlantic salmon (Salmo salar L.) in the wild. Using scale samples of over ...
    • Iteroparity and its contribution to life-history variation in Atlantic salmon 

      Persson, Lo; Raunsgard, Astrid; Thorstad, Eva Bonsak; Østborg, Gunnel Marie; Urdal, Kurt; Sægrov, Harald; Ugedal, Ola; Hindar, Kjetil; Karlsson, Sten; Fiske, Peder; Bolstad, Geir Hysing (Peer reviewed; Journal article, 2023)
      Evolution of iteroparity is shaped by the trade-off between current and future reproduction.We studied variation in iteroparity among 205 050 individual Atlantic salmon caught in 179 rivers spanning 14◦ of latitude. The ...
    • Life-history evolution under fluctuating density-dependent selection and the adaptive alignment of pace-of-life syndromes 

      Wright, Jonathan; Bolstad, Geir Hysing; Araya-Ajoy, Yimen; Dingemanse, Niels J. (Journal article; Peer reviewed, 2018)
      We present a novel perspective on life-history evolution that combines recent theoretical advances in fluctuating density-dependent selection with the notion of pace-of-life syndromes (POLSs) in behavioural ecology. These ...
    • Mutation predicts 40 million years of fly wing evolution 

      Houle, David; Bolstad, Geir Hysing; van der Linde, Kim; Hansen, Thomas F (Journal article; Peer reviewed, 2017)
      Mutation enables evolution, but the idea that adaptation is also shaped by mutational variation is controversial1–4. Simple evolutionary hypotheses predict such a relationship if the supply of mutations constrains evolution5,6, ...
    • Novel microsatellite markers for Dalechampia scandens (Euphorbiaceae) and closely related taxa:application to studying a species complex 

      Falahati-Anbaran, Mohsen; Stenøien, Hans K.; Bolstad, Geir Hysing; Hansen, Thomas F; Pérez‐Barrales, Rocio; Armbruster, William Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2016)
    • Supplementary stocking selects for domesticated genotypes 

      Hagen, Ingerid Julie; Jensen, Arne Johan; Bolstad, Geir Hysing; Diserud, Ola Håvard; Hindar, Kjetil; Lo, Håvard; Karlsson, Sten (Journal article; Peer reviewed, 2019)
      Stocking of hatchery produced fish is common practise to mitigate declines in natural populations and may have unwanted genetic consequences. Here we describe a novel phenomenon arising where broodstock used for stocking ...
    • Vurdering av Langvatn kraftverk som et potensielt vandringshinder for laks og sjøaure i Ranaelva 

      Bolstad, Geir Hysing; Ugedal, Ola (NINA Rapport;1180, Research report, 2015)
      Langvatn kraftverk har utløp i munningsområdet til Ranaelva. Vannføringen gjennom dette kraft-verket er ofte større enn i Ranaelva i perioden når anadrome laksefisk vandrer opp i elva. Kraft-verket er derfor et potensielt ...
