    • Evidence of temperature control on mesopelagic fish and zooplankton communities at high latitudes 

      Chawarski, Julek; Klevjer, Thor A.; Coté, David; Geoffroy, Maxime (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-06)
      Across temperate and equatorial oceans, a diverse community of fish and zooplankton occupies the mesopelagic zone, where they are detectable as sound-scattering layers. At high latitudes, extreme day-night light cycles may limit the range of some species, while at lower latitudes communities are structured by dynamic ocean processes, such as temperature. Using acoustic and oceanographic ...

    • Resource partitioning may limit interspecific competition among Arctic fish species during early life 

      Bouchard, Caroline; Chawarski, Julek; Geoffroy, Maxime; Klasmeier, Apasiri; Møller, Eva Friis; Mohn, Christian; Agersted, Mette Dalgaard (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-28)
      Arctic cod (Boreogadus saida) strongly dominates the ichthyoplankton assemblages of High Arctic seas, hence competition with other native species seldom has been studied. Yet, interspecific competition could negatively impact the survival of early life stages of fishes in Arctic areas where higher diversity prevails. We surveyed the ichthyoplankton community of the Greenland Sea, in August–September ...
