      Åström, Emmelie; Sen, Arunima; Carroll, Michael Leslie; Carroll, JoLynn (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-21)
      Cold-seep benthic communities in the Arctic exist at the nexus of two extreme environments; one reflecting the harsh physical extremes of the Arctic environment and another reflecting the chemical extremes and strong environmental gradients associated with seafloor seepage of methane and toxic sulfide-enriched sediments. Recent ecological investigations of cold seeps at numerous locations on the ...
    • Higher spatial than seasonal variation in floodplain soil eukaryotic microbial communities 

      Fournier, Bertrand; Samaritani, Emanuela; Frey, Beat; Seppey, Christophe Victor W.; Lara, Enrique; Heger, Thierry J.; Mitchell, Edward A.D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-10)
      Beta diversity is a key component of biodiversity with implications ranging from species dynamics to ecosystem functioning. However, β-diversity and its drivers have received little attention, especially for micro-eukaryotes which play key roles in soil functioning. We studied the diversity of soil micro-eukaryotes in a Swiss lowland floodplain using high-throughput Illumina sequencing of soil DNA. ...
    • Stretching the Rule of Law: How the Norwegian resistance movement influenced the provisional treason decrees of the exile government, 1944-1945 

      Borge, Baard Herman; Vaale, Lars-Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-16)
      This article examines the role of the Norwegian resistance movement ‘Hjemmefronten’ (the Home Front, HF) as a political interest group during the exile government’s formulation of provisional laws meant for the postwar reckoning with Norwegian collaborators and foreign war criminals. The article argues that the resistance through its judicial committee in Oslo had a decisive impact on the final ...

      Two adult specimens of the tropical to subtropical fish species <i>Diretmichthys parini</i> are reported from the North Sea and the northern Norwegian Sea, respectively. Both were accidentally caught as bycatch by commercial trawlers. Although not uncommon in Icelandic waters, it has not been documented from the Nordic Seas previously. In light of the major currents and water temperatures in the ...
    • Overexpression of T-bet, GATA-3 and TGF-ß induces IFN-γ, IL-4/13A, and IL-17A expression in Atlantic salmon 

      Slettjord, Tiril Hoffstrøm; Sekkenes, Hege J.; Chi, Heng; Bøgwald, Jarl; Swain, Trilochan; Dalmo, Roy Ambli; Swain, Jaya Kumari (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-20)
      The overexpression of <i>GATA-3, T-bet</i> and <i>TGF-ß</i> may theoretically induce <i>IL-4/A, IFN-γ</i> and <i>IL-17A</i> expression, respectively. Whether this also applies to fish is not yet known. The plasmid vectors encoding reporter gene (RFP)-tagged <i>T-bet, GATA-3</i> and <i>TGF-ß</i> were used as overexpression tools, transfected into cells or injected intramuscularly to monitor the ...

    • The Exploitation-exploration Dilemma of Fishing Vessels with Institutionally Protected Quota Shares 

      Hannevig, Hilde; Bertheussen, Bernt Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-16)
      It is an established “truth” in the literature that a company which restricts itself to utilize existing resources without exploring new business opportunities is doomed to fail in the long run. An underlying premise for the claim is that the competition arena is dynamic and organized according to free competition principles. This study, however, examines whether it is more profitable for a fishing ...
    • RNA profiling identifies novel, photoperiodhistory dependent markers associated with enhanced saltwater performance in juvenile Atlantic salmon 

      Iversen, Marianne; Mulugeta, Teshome Dagne; Blikeng, Børge Gellein; West, Alexander Christopher; Jørgensen, Even Hjalmar; Sandve, Simen Rød; Hazlerigg, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-08)
      Atlantic salmon migrate to sea following completion of a developmental process known as smolting, which establishes a seawater (SW) tolerant phenotype. Smolting is stimulated by exposure to long photoperiod or continuous light (LL) following a period of exposure to short photoperiod (SP), and this leads to major changes in gill ion exchange and osmoregulatory function. Here, we performed an RNAseq ...
    • Storm-driven across-shelf oceanic flows into coastal waters 

      Jones, Sam; Inall, Mark; Porter, Marie; Graham, Jennifer A.; Cottier, Finlo Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-02)
      The North Atlantic Ocean and northwest European shelf experience intense low-pressure systems during the winter months. The effect of strong winds on shelf circulation and water properties is poorly understood as observations during these episodes are rare, and key flow pathways have been poorly resolved by models up to now. We compare the behaviour of a cross-shelf current in a quiescent period in ...

      Strømseth, Cathrin Amundsen (Master thesis; Mastergradsoppgave, 2019-06-11)
      Denne masteroppgaven fokuser på begrepet organisatorisk identitet i Forsvarsbygg, og hvordan de ansatte opplever den vs den formelle uttalte identiteten til Forsvarsbygg er. Identitet dreier seg om hvem vi er og om hvordan vi grunnleggende definerer oss selv. Slik er det også ved organisasjonsidentitet, det dreier seg om oss og hvem vi er som organisasjon. Oppgaven tar utgangspunkt i Albert & ...
    • Soil chemistry changes beneath decomposing cadavers over a one-year period 

      Szelecz, Ildiko; Koenig, Isabelle; Seppey, Christophe Victor W.; Le Bayon, Renee-Claire; Mitchell, Edward A.D. (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-03-06)
      Decomposing vertebrate cadavers release large, localized inputs of nutrients. These temporally limited resource patches affect nutrient cycling and soil organisms. The impact of decomposing cadavers on soil chemistry is relevant to soil biology, as a natural disturbance, and forensic science, to estimate the postmortem interval. However, cadaver impacts on soils are rarely studied, making it difficult ...
    • First record of experimentally induced salmon gill poxvirus disease (SGPVD) in Atlantic salmon (Salmo salar L.) 

      Thoen, Even; Tartor, Haitham; Amundsen, Marit; Dale, Ole Bendik; Sveinsson, Karoline Overn; Rønning, Hans Petter; Grønneberg, Estelle; Dahle, Maria; Gjessing, Mona Cecilie (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-07)
      Salmon gill poxvirus (SGPV) infection is a common denominator in many cases of complex gill disease in the Norwegian salmon farming industry and may, as a single agent infection, result in salmon poxvirus disease (SGPVD). Experiences from the field suggest that stress may be a decisive factor for the induction of SGPVD. Here we investigated the effect of stress hormone treatment on SGPV kinetics and ...

    • Mikroalger i fôr, ny løsning for å redusere lusepåslag på laks – Faglig sluttrapport 

      Hustad, Anette; Vang, Birthe; Eilertsen, Hans Christian; Siikavuopio, Sten Ivar; Sæther, Bjørn-Steinar; Svalheim, Ragnhild Aven; Hansen, Espen Holst; Svenning, Jon Brage; Kousoulaki, Katerina; Whitaker, Ragnhild (Research report; Forskningsrapport, 2020-05)
      I dette prosjektet har vi testet ut en hypotese om at ved å erstatte vegetabilske oljer i fôr til oppdrettslaks med marine oljer, vil man kunne redusere lusepåslag hos laks. Vi har fôret laks med fire ulike fôr, der proteininnholdet er det samme, men oljen er variert. De ulike fôrene vi brukte var kontrollfôr som var standardfôr med vegetabilsk olje, og tre ulike testfôr der vegetabilsk olje ble ...
    • The economic determinants of tourism seasonality: A case study of the Norwegian tourism industry 

      Xie, Jinghua (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-26)
      Since seasonality has long been recognized as one of the most critical problems in the tourism industry, many studies have been conducted to investigate its reasons. Nevertheless, almost all the studies focus on climate and institutional reasons, ignoring the possible economic determinants. In this study, we use econometric models to estimate how economic factors such as tourist’s income, the relative ...
    • OMT: en studie om spesialistens motivasjon for en karriere i Hæren
