    • Missing the marine forest for the trees 

      Wernberg, Thomas; Filbee-Dexter, Karen (Journal article; Peer reviewed, 2019)

    • New evidence for the establishment of coastal cod Gadus morhua in Svalbard fjords 

      Spotowitz, Lisa; Johansen, Torild; Hansen, Agneta; Berg, Erik; Stransky, Christoph; Fischer, Philipp (Peer reviewed; Journal article, 2022)
      The Arctic is experiencing increasing water temperatures, leading to a northward shift of Atlantic species into Arctic waters. Arctic marine ecosystems are therefore subject to substantial changes in species distributions ...
    • Origin of marine invertebrate larvae on an Arctic inflow shelf 

      Descoteaux, Raphaelle; Huserbråten, Mats Brockstedt Olsen; Jørgensen, Lis Lindal; Renaud, Paul Eric; Ingvaldsen, Randi Brunvær; Ershova, Elizaveta; Bluhm, Bodil (Peer reviewed; Journal article, 2022)
