    • Functional diversity of the Barents Sea fish community 

      Wiedmann, Magnus Aune; Aschan, Michaela; Certain, Gregoire; Dolgov, Andrey V.; Greenacre, Michael; Johannesen, Edda; Planque, Benjamin; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      This paper provides the first assessment of the functional diversity (FD) of the Barents Sea fish community. FD is recognized as an important driver of ecosystem functions and, thus, governs the adaptability of ecosystems in the face of disturbance. We integrate ecosystem survey data with an extensive trait matrix and show that fish FD displayed large spatial variation. The study period (2004 to ...

    • Increased functional diversity warns of ecological transition in the Arctic 

      Frainer, André; Primicerio, Raul; Dolgov, Andrey V.; Fossheim, Maria; Johannesen, Edda; Lind, Sigrid; Aschan, Michaela (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-07)
      As temperatures rise, motile species start to redistribute to more suitable areas, potentially affecting the persistence of several resident species and altering biodiversity and ecosystem functions. In the Barents Sea, a hotspot for global warming, marine fish from boreal regions have been increasingly found in the more exclusive Arctic region. Here, we show that this shift in species distribution ...

    • 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 ...
