    • A cold-water fish striving in a warming ocean: Insights from whole-genome sequencing of the Greenland halibut in the Northwest Atlantic 

      Ferchaud, Anne-Laure; Normandeau, Eric; Babin, Charles; Præbel, Kim; Hedeholm, Rasmus; Audet, Celine; Morgan, Joanne; Walkusz, Wojciech; Sirois, Pascal; Bernatchez, Louis (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-02)
      Characterizing the extent of genetic differentiation among individuals and its distribution across the genome is increasingly important to inform both conservation and management of exploited species. The Greenland Halibut is one of the main demersal fish species to be commercially exploited in Eastern Canada, and accurate information on geographic population structure and local adaptation is required ...

    • Genetic population structure and variation at phenology‐related loci in anadromous Arctic char (Salvelinus alpinus) 

      Madsen, Rikke; Jacobsen, Magnus W; O´Malley, Kathleen G; Nygaard, Rasmus; Præbel, Kim; Jonsson, Bjarni; Pujolar, Jose M; Fraser, Dylan J; Bernatchez, Louis; Hansen, Michael M (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-03)
      The Arctic will be especially affected by climate change, resulting in altered seasonal timing. Anadromous Arctic char (<i>Salvelinus alpinus</i>) is strongly influenced by sea surface temperature (SST) delimiting time periods available for foraging in the sea. Recent studies of salmonid species have shown variation at phenology‐related loci associated with timing of migration and spawning. We ...

    • Phenotype-environment association of the oxygen transport system in trimorphic European whitefish (Coregonus lavaretus) populations 

      Evans, Melissa; Præbel, Kim; Peruzzi, Stefano; Amundsen, Per-Arne; Bernatchez, Louis (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-05-23)

    • Polygenic selection drives the evolution of convergent transcriptomic landscapes across continents within a Nearctic sister species complex 

      Rougeux, Clement; Gagnaire, Pierre‐Alexandre; Præbel, Kim; Seehausen, Ole; Bernatchez, Louis (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-03)
      In contrast to the plethora of studies focusing on the genomic basis of adaptive phenotypic divergence, the role of gene expression during speciation has been much less investigated and consequently less understood. Yet, the convergence of differential gene expression patterns between closely related species‐pairs might reflect the role of natural selection during the process of ecological speciation. ...

    • Speciation reversal in European whitefish (Coregonus lavaretus (L.)) caused by competitor invasion 

      Bhat, Shripathi; Amundsen, Per-Arne; Knudsen, Rune; Gjelland, Karl Øystein; Fevolden, Svein-Erik; Bernatchez, Louis; Præbel, Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Invasion of exotic species has caused the loss of biodiversity and imparts evolutionary and ecological changes in the introduced systems. In northern Fennoscandia, European whitefish (Coregonus lavaretus (L.)) is a highly polymorphic species displaying adaptive radiations into partially reproductively isolated and thus genetically differentiated sympatric morphs utilizing the planktivorous and ...

    • Strong water stratification provides a refuge for rainbow smelt larvae Osmerus mordax in a sub-arctic estuary (Lake Melville, Labrador) 

      Small, Tiffany; Cyr, Frédéric; McCarthy, James; Sutton, Jordan; Bernatchez, Louis; Geoffroy, Maxime (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-02)
      Estuaries provide nurseries for early life stages of fish that rely on the interaction between fresh- and saltwater. The 250 km long Lake Melville spans 2100 km2 and is the largest estuary of Labrador (northeastern Canada). This sub-arctic fjard hosts freshwater, anadromous, and marine fishes on which depend marine mammals and seabirds, but also coastal communities. Yet, how different fish species ...
