    • Climate warming enhances polar cod recruitment, at least transiently 

      Bouchard, Caroline; Geoffroy, Maxime; LeBlanc, Mathieu; Majewski, Andrew; Gauthier, Stéphane; Walkusz, Wojciech; Reist, James D.; Fortier, Louis (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-27)
      Polar cod (Boreogadus saida) is the dominant forage fish in Arctic seas and the main prey of the ringed seal (Pusa hispida), the beluga (Delphinapterus leucas) and several seabird species. Changes in the abundance of polar cod will have cascading effects on arctic marine ecosystems. We tested the hypothesis that an earlier sea ice breakup and warmer sea surface temperatures (SST) in spring-summer ...

    • Zooplankton assemblages along the North American Arctic: Ecological connectivity shaped by ocean circulation and bathymetry from the Chukchi Sea to Labrador Sea 

      Darnis, Gérald; Geoffroy, Maxime; Dezutter, Thibaud; Aubry, Cyril; Massicotte, Philippe; Brown, Tanya; Babin, Marcel; Cote, David; Fortier, Louis (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-09)
      We defined mesozooplankton biogeography in the North American Arctic to elucidate drivers of biodiversity, community structure, and biomass of this key component of the Arctic marine ecosystem. A multivariate analysis identified four mesozooplankton assemblages: Arctic-oceanic, Arctic-shelf, Coastal-Hudson, and Labrador Sea. Bathymetry was a major driver of the distribution of these assemblages. ...
