    • Benthic transition zones in the Atlantic gateway to a changing Arctic ocean 

      Jørgensen, Lis Lindal; Pecuchet, Laurene; Ingvaldsen, Randi Brunvær; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-06)
      The biogeographic transition from boreal to Arctic marine communities entails a strong taxonomic and functional turnover. Communities living in these areas are being strongly affected by climate warming with rapid reorganizations and change in ecosystem functioning. We assess the megabenthic species composition and functional character in a transition zone around Svalbard. The relationships between ...

    • Large-scale patterns in community structure of benthos and fish in the Barents Sea 

      Johannesen, Edda; Jørgensen, Lis Lindal; Fossheim, Maria; Primicerio, Raul; Greenacre, Michael; Ljubin, Pavel A.; Dolgov, Andrey V.; Ingvaldsen, Randi; Anisimova, Natalya A.; Manushin, Igor E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-04-23)
      Biogeographical patterns have an ecological basis, but few empirical studies possess the necessary scale and resolution relevant for investigation. The Barents Sea shelf provides an ideal study area, as it is a transition area between Atlantic and Arctic regions, and is sampled by a comprehensive survey of all major functional groups. We studied spatial variation in species composition of demersal ...

    • Novel feeding interactions amplify the impact of species redistribution on an Arctic food web 

      Pecuchet, Laurene; Blanchet, Marie-Anne; Frainer, Andre barbosa; Husson, Bérengère; Jørgensen, Lis Lindal; Kortsch, Susanne; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-01)
      Species are redistributing globally in response to climate warming, impacting ecosystem functions and services. In the Barents Sea, poleward expansion of boreal species and a decreased abundance of Arctic species are causing a rapid borealization of the Arctic communities. This borealization might have profound consequences on the Arctic food web by creating novel feeding interactions between ...

    • Responding to global warming: New fisheries management measures in the Arctic 

      Jørgensen, Lis Lindal; Bakke, G.; Hoel, Alf Håkon (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-01)
      The northernmost commercial fisheries in the world take place in the northern Barents Sea up to around 80° N. This is an area where global warming is particularly intense and where large, previously ice-covered areas are now more accessible to fishing vessels. This raised questions whether existing conservation and management measures are adequate. In this paper, we discuss the process of developing ...

    • Spatio-temporal turnover and drivers of bentho-demersal community and food web structure in a high-latitude marine ecosystem 

      Pecuchet, Laurene; Jørgensen, Lis Lindal; Dolgov, Andreyv V.; Eriksen, Elena; Husson, Berengere; Skern-Mauritzen, Mette; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-14)
      Aim: Assess the spatial and temporal turnover of bentho-demersal marine fauna by integrating ecological metrics at the community and food web levels and evaluate their main environmental and anthropogenic drivers.<p> <p>Location: Barents Sea. <p>Method: We analysed data of benthic and bentho-pelagic fish and megabenthic invertebrates caught in the Barents Sea ecosystem survey in August–Septem ...
