    • Lack of strong seasonality in macrobenthic communities from the northern Barents Sea shelf and Nansen Basin 

      Jorda Molina, Eric; Sen, Arunima; Bluhm, Bodil Annikki Ulla Barbro; Renaud, Paul Eric; Włodarska-Kowalczuk, Maria; Legeżyńska, Joanna; Oleszczuk, Barbara; Reiss, Henning (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-12)
      The Barents Sea has been coined ‘the Arctic hotspot’ of climate change due to the rapidity with which environmental changes are taking place. This transitional domain from Atlantic to Arctic waters is home to highly productive benthic communities. This system strongly fluctuates on a seasonal basis in its sympagic-pelagicbenthic coupling interactions, with potential effects on benthic standing ...

    • Over 20% of marine fishes shifting in the North and Barents Seas, but not in the Norwegian Sea 

      Gordo Vilaseca, Francesc; Pecuchet, Laurene Anne Marie; Coll, Marta; Reiss, Henning; Jueterbock, Alexander; Costello, Mark John (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-31)
      Climate warming generally induces poleward range expansions and equatorward range contractions of species’ environmental niches on a global scale. Here, we examined the direction and magnitude of species biomass centroid geographic shifts in relation to temperature and depth for 83 fish species in 9,522 standardised research trawls from the North Sea (1998–2020) to the Norwegian (2000–2020) and ...

    • Seafloor warm water temperature anomalies impact benthic macrofauna communities of a high-Arctic cold-water fjord 

      Jorda Molina, Eric; Renaud, Paul Eric; Silberberger, Marc J.; Sen, Arunima; Bluhm, Bodil; Carroll, Michael Leslie; Ambrose, William; Cottier, Finlo Robert; Reiss, Henning (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-05)
      Amid the alarming atmospheric and oceanic warming rates taking place in the Arctic, western fjords around the Svalbard archipelago are experiencing an increased frequency of warm water intrusions in recent decades, causing ecological shifts in their ecosystems. However, hardly anything is known about their potential impacts on the until recently considered stable and colder northern fjords. We ...

    • Strong macrobenthic community differentiation among sub-Arctic deep fjords on small spatial scales 

      Kokarev, Valentin; Tachon, Mathieu; Austad, Marthe; Mcgovern, Maeve; Reiss, Henning (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-16)
      Fjords play an important role in carbon cycling and sequestration, but the burial of organic matter in sediments strongly depends on the composition of macrobenthic communities. We studied three deep, sub-Arctic fjords located in northern Norway to assess the community differentiation of neighbouring fjords and the underlying environmental drivers. The fjords have relatively deep depositional basins ...
