      Plant litter represents a major basal resource in streams, where its decomposition is partly regulated by litter traits. Litter-trait variation may determine the latitudinal gradient in decomposition in streams, which is mainly microbial in the tropics and detritivore-mediated at high latitudes. However, this hypothesis remains untested, as we lack information on large-scale trait variation for ...
    • The rise and decline of fishing industry support – with a translation from Norwegian of Bjørn S. Brochmann's 1981 article ‘long-term effects of government support to the fisheries’ 

      Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-21)
      Input and output measures, including the use of (Pigou) taxes, have been recommended to bridge the gap between average and marginal revenues in fisheries. Several countries have improved management, but few have followed the fiscal recommendations. On the contrary, subsidies that can expand capacity and effort have been and still are used. For decades, international organizations such as the WTO, ...

      Blanchet, Marie-Anne; Primicerio, Paul; Frainer, Andrè; Kortsch, Susanne; Skern-Mauritzen, Mette; Dolgov, Andrey V.; Aschan, Michaela (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-26)
      Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 marine mammals. As a group, they directly connect to the most central species (i.e cod and haddock) in the Barents Sea (i.e. cod and haddock) and consume over half of the available ...
    • Roles for advisory science in the International Council for the Exploration of the Sea (ICES) 

      Linke, Sebastian; Nielsen, Kåre Nolde; Ramirez-Monsalve, Paulina (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-12)
      What role should science take when providing advice in support of policy and politics? Should a provider of science-based advice have its own position on the issues it provides advise on? Or should it be as impartial as possible from the value and policy context of the advice? This theme, long debated, gained new attention in fisheries and marine governance. Starting from theoretical concepts and ...
    • Røde blodceller - er de sensorer for laksens helsetilstand? 

      Dahle, Maria; Gjessing, Mona Cecilie; Tsoulia, Thomais (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-11)
      Det er ikke tvil om at røde blodceller er livsviktige, siden de forsyner kroppen med oksygen, og laksens blodceller frakter oksygen kanskje enda mer effektivt enn våre blodceller gjør. Men det er ikke det eneste de røde blodcellene i laksen kan. De har en cellekjerne som kan uttrykke en mengde gener - de har sensorer for virus og stresshormoner og mye mer - og får signaler fra ...
