    • Climate and juvenile recruitment as drivers of Arctic cod (Boreogadus saida) dynamics in two Canadian Arctic seas 

      Herbig, Jennifer; Fisher, Jonathan; Bouchard, Caroline; Niemi, Andrea; LeBlanc, Mathieu; Majewski, Andrew; Gauthier, Stéphane; Geoffroy, Maxime (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-22)
      Arctic cod (Boreogadus saida) is the most abundant forage fish species in Arctic seas and plays a pivotal role in the transfer of energy between zooplankton and top predators. The dominance of Arctic cod and the Arctic’s relatively low biodiversity interact such that changing population dynamics of Arctic cod have cascading effects on whole Arctic marine ecosystems. Over the last decades, warming ...

    • 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 ...
