    Svenson, Wolf Jost Frithiof Erten-Alexa; Pietrzak, Piotr; Launer, Markus A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-16)
    To make good decisions, employees must manage their own intuitions and be able to anticipate decision-making in their work environment. How well this is accomplished has significant consequences for the workplace. A closer examination indicates that individuals utilize various types of intuition. People’s work context is frequently omitted from studies on the use of intuition, resulting in a ...
  • Carnobacteria in fish 

    Ringø, Einar (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-19)
    Carnobacterium is a genus of Gram-positive bacteria, within family Carnobacteriaceae, and they are catalase- and oxidase-negative, non-sporing bacteria with properties such as CO<sup>2</sup> and L (+)- lactic acid production from glucose, but they are not able to grow on acetate agar. They are ubiquitous lactic acid bacteria and have been isolated from both cold and temperate environments, and ...

  • Uncovering neutral and adaptive genomic differentiation among European perch with brackish water and freshwater origin in the western Baltic Sea region 

    Skovrind, Mikkel; Pacheco, George; Christensen, Emil Aputsiaq Flindt; Gopalakrishnan, Shyam; Fietz, Katharina; Holm-Hansen, Tore Hejl; Vieira, Filipe Garrett; Krag, Marcus Anders; Carl, Henrik; Gilbert, Marcus Thomas Pius; Olsen, Morten Tange; Møller, Peter Daniel Rask (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-13)
    Environmental variation across the range of wild species can lead to local adaptations. The Baltic Sea was formed when the Fenno-Scandian ice sheet retreated around 12 thousand years ago, creating a new brackish water habitat colonised by both marine and freshwater fish species. The European perch (Perca fluviatilis) is a predatory freshwater fish with a large geographical distribution across ...
  • Reducing plastic pollution caused by demersal fisheries 

    Grimaldo, Eduardo; Karl, Christian; Alvestad, Anja Helene; Persson, Anna-Maria Märta Ruth; Kubowicz, Stephan; Olafsen, Kjell; Hatlebrekke, Hanne Hjelle; Lilleng, Grethe; Brinkhof, Ilmar Leone (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-07)
    Marine microplastics generated by wear and tear of bottom trawls and demersal seines during their service life is a growing environmental concern that requires immediate attention. In Norway, these fishing gears account for more than 70 % of the landings of demersal fish species, but they are also the leading sources of microplastics generated by fisheries. Because these two fishing gears are widely ...
