Stress Responses and Gut Health of Post-Smolt Atlantic salmon (Salmo salar) Exposed to Chronic Sub-Lethal Level of Hydrogen Sulphide in a Recirculating Aquaculture System
(Master thesis, 2023-06-02)In recent years, episodes of acute Atlantic salmon mass mortalities in recirculating aquaculture systems (RAS) have been associated with the formation of hydrogen sulphide (H2S), a toxic gas known for its distinct "rotten ... -
Strong microsite control of seedling recruitment in tundra
(Peer reviewed; Journal article, 2010-12-19)The inclusion of environmental variation in studies of recruitment is a prerequisite for realistic predictions of the responses of vegetation to a changing environment. We investigated how seedling recruitment is affected ... -
Structural and functional analyses of the neutral amino acid transporter SLC7A10 in adipocytes
(Master thesis, 2021-11-22) -
Structural elements determining NAMPT activity
(Doctoral thesis, 2023-06-20)Nikotinamidadenindinukleotid (NAD) er en hydridbærer involvert i redoksreaksjoner i metabolismen. I tillegg er NAD+ et substrat av enzymer som medierer vitale NAD+-avhengige prosesser, der dinukleotidet spaltes, og frigjør ... -
Structure and functioning of four North Atlantic ecosystems - A comparative study
(Journal article; Peer reviewed, 2020)The epi- and mesopelagic ecosystems of four sub-polar ocean basins, the Labrador, Irminger, Iceland and Norwegian seas, were surveyed during two legs from Bergen, Norway, to Nuuk, Greenland, and back to Bergen. The survey ... -
Structure prediction of honey bee vitellogenin: a multi-domain protein important for insect immunity
(Journal article; Peer reviewed, 2022)Vitellogenin (Vg) has been implicated as a central protein in the immunity of egg-laying animals. Studies on a diverse set of species suggest that Vg supports health and longevity through binding to pathogens. Specific ... -
Studenters opplevelse av meningsskapende samsvar
(Master thesis, 2022-06-01)Meningsskapende samsvar er en student-sentrert modell utviklet av pedagogen John Biggs, som hevdes å forbedre kvaliteten på læring og undervisning. Med et konstruktivistisk grunnsyn tar modellen sikte på å skape et samsvar ... -
Studie av kysttorskbestander i Troms og Finnmark basert på tråldata, 1995-2004 : statistiske analyser av mengdeutvikling, geografiske sammenhenger, lengdefrekvensfordeling og feilkilder i trålmetodikk
(Master thesis, 2006)Bestanden av kysttorsken (Gadus morhua) har i følge International Council for the Explorations of the Sea (ICES) og Havforskningsinstituttet (HI) vist sammenhengende tilbakegang siden 1994. Tråldata fra HI i perioden ... -
Studies on the mitochondrial genome and rDNA genes from the salmon louse, Lepeophtheirus salmonis
(Doctoral thesis, 2006-02-24) -
Studies on the promiscuous xenobiotic receptor (PXR, NR1I2) in zebrafish: antibody characterisation and genetic variation in zebrafish embryos
(Master thesis, 2014-06-02)The promiscuous xenobiotic receptor (PXR, NR1I2, also denoted pregnane X receptor) is a nuclear receptor which regulates the transcription of genes involves in the biotransformation of endogenous and xenobiotic compounds. ... -
Study of Ecdysone receptor and Ultraspiracle in the salmon louse (Lepeophtheirus salmonis)
(Master thesis, 2015-05-31)The salmon louse (Lepeophtheirus salmonis) is a parasite living on mucus, skin and blood of salmonids fishes. L. salmonis causes lesions and infections on fish fins and skins and such physical damages often lead to other ... -
Studying the waste recycling potential of naturally occurring polychaetes on benthic trays under a Norwegian fish farm
(Master thesis, 2018-06-26)With an increasing salmon industry comes an increasing amount of waste released into the environment, impacting benthic environments in particular. This study investigated the potential of utilizing naturally occurring ... -
Sub-populations of coastal cod with different behaviour and life-history strategies
(Peer reviewed; Journal article, 2004-02-19)This study provides evidence of countergradient variations in life-history traits among coastal cod Gadus morhua off the Norwegian coast, suggesting the existence of sub-populations. One-yr-old wild-caught individuals from ... -
Substituted Two- To Five-Ring Polycyclic Aromatic Compounds Are Potent Agonists of Atlantic Cod (Gadus morhua) Aryl Hydrocarbon Receptors Ahr1a and Ahr2a
(Journal article; Peer reviewed, 2021)Polycyclic aromatic hydrocarbons (PAHs) are among the most toxic and bioavailable components found in petroleum and represent a high risk to aquatic organisms. The aryl hydrocarbon receptor (Ahr) is a ligand-activated ... -
Suicidality among children and youth in Nordic child welfare services: A systematic review
(Journal article; Peer reviewed, 2021)Existing research has established child welfare (CW) clients as a vulnerable group for developing negative life trajectories, including mental health problems, work- and education-related challenges and premature mortality. ... -
Sulfate homeostasis in Atlantic salmon is associated with differential regulation of salmonid-specific paralogs in gill and kidney
(Journal article; Peer reviewed, 2021)Sulfate (SO2−4) regulation is challenging for euryhaline species as they deal with large fluctuations of SO2−4 during migratory transitions between freshwater (FW) and seawater (SW), while maintaining a stable plasma SO2−4 ... -
