Proteomic Tools for Food and Feed Authentication
(Doctoral thesis, 2023-03-10)På grunn av globalt økende etterspørsel etter mat og fôr, introduseres nye proteinholdige ingredienser i matsystemene våre i økende skala. Innføring av nye ingredienser og introduksjon av sirkulære matsystemer gir nye ... -
Proteomics and lipidomics analyses reveal modulation of lipid metabolism by perfluoroalkyl substances in liver of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2020)The aim of the present study was to investigate effects of defined mixtures of polycyclic aromatic hydrocarbons (PAHs) and perfluoroalkyl substances (PFASs), at low, environmentally relevant (1× = L), or high (20× = H) ... -
Protozan ectosymbionts on Atlantic salmon (Salmo salar L.) in a Hatchery in Hordaland, Western Norway: Morphology and Epizootiology
(Master thesis, 2003)Protozoan ectosymbionts are commonly found on salmonids in Norwegian lakes and rivers. Salmon in hatcheries supplied with water from such watercourses are often infected with such organisms. Despite extensive salmon ... -
The proximate architecture for decision-making in fish
(Peer reviewed; Journal article, 2016-09)Evolution has since the very beginning resulted in organisms which can sort fitness-related information from noise, evaluate it and respond to it. In animals, the architecture for proximate control of behaviour and physiology ... -
Proximity to small-scale inland and coastal fisheries is associated with improved income and food security
(Journal article; Peer reviewed, 2022)Poverty and food insecurity persist in sub-Saharan Africa. We conducted a secondary analysis of nationally representative data from three sub-Saharan Africa countries (Malawi, Tanzania, and Uganda) to investigate how both ... -
Public health concern behind the exposure to persistent organic pollutants and the risk of metabolic diseases
(Peer reviewed; Journal article, 2012-04-20)Background: Persistent organic pollutants (POPs) are hazardous chemicals omnipresent in our food chain, which have been internationally regulated to ensure public health. Initially described for their potency to affect ... -
Pushing the limits of photoreception in twilight conditions: The rod-like cone retina of the deep-sea pearlsides
(Peer reviewed; Journal article, 2017)Most vertebrates have a duplex retina comprising two photoreceptor types, rods for dim-light (scotopic) vision and cones for bright-light (photopic) and color vision. However, deep-sea fishes are only active in dim-light ... -
Putting small fish on the table: the underutilized potential of small indigenous fish to improve food and nutrition security in East Africa
(Journal article; Peer reviewed, 2023)Sub-Saharan Africa has a high prevalence of food insecurity. Small pelagic fish such as Silver cyprinid (Rastrineobola argentea) which is indigenous to Lake Victoria, can be a nutritious animal sourced food that contributes ... -
The pyramidellidae (gastropoda, heterobranchia) of Norway and adjacent waters. A taxonomic review
(Peer reviewed; Journal article, 2014)This monograph gives a taxonomic treatment of all 54 ‘species’ of Pyramidellidae reported from Norwegian and adjacent waters. Two species, Parthenina wikanderi n.sp.and Eulimella frielei n.sp., are described as new and ... -
qPCR screening for Yersinia ruckeri clonal complex 1 against a background of putatively avirulent strains in Norwegian aquaculture
(Journal article; Peer reviewed, 2022)Although a number of genetically diverse Yersinia ruckeri strains are present in Norwegian aquaculture environments, most if not all outbreaks of yersiniosis in Atlantic salmon in Norway are associated with a single specific ... -
Quantification and localization of StAR expression in Atlantic cod ovaries
(Master thesis, 2009-06-02)Steroidogenesis is essential for the production of sex steroids, and therefore also the sexual maturation process. The rate-limiting step in steroidogenesis is the movement of cholesterol from the outer to the inner ... -
Quantification of grazing efficacy, growth and health score of different lumpfish (Cyclopterus lumpus L.) families: possible size and gender effects
(Journal article; Peer reviewed, 2021)To investigate the possible family influence on sea lice grazing of lumpfish on Atlantic salmon, ten families of lumpfish (N = 480) with a mean (± SD) weight of 54.8 ± 9.2 g were distributed among ten sea cages (5 × 5 × 5 ... -
Quantifying recent ecological changes in remote lakes of North America and Greenland using sediment diatom assemblages
(Peer reviewed; Journal article, 2010-04-02)Background Although arctic lakes have responded sensitively to 20th-century climate change, it remains uncertain how these ecological transformations compare with alpine and montane-boreal counterparts over the same interval. ... -
Quantifying the roles of seed dispersal, filtering, and climate on regional patterns of grassland biodiversity
(Journal article; Peer reviewed, 2020)Seed dispersal and local filtering interactively govern community membership and scale up to shape regional vegetation patterns, but data revealing how and why particular species are excluded from specific communities in ... -
Quantitative assessment of visual microscopy as a tool for microplastic research: Recommendations for improving methods and reporting
(Journal article; Peer reviewed, 2022)Microscopy is often the first step in microplastic analysis and is generally followed by spectroscopy to confirm material type. The value of microscopy lies in its ability to provide count, size, color, and morphological ... -
Quantitative genetics of breeding coloration in sand lizards; genic capture unlikely to maintain additive genetic variance
(Journal article; Peer reviewed, 2023)Sexual selection on fitness-determining traits should theoretically erode genetic variance and lead to low heritability. However, many sexually selected traits maintain significant phenotypic and additive genetic variance, ... -
Quantitative microbial ecology off the northern Antarctic Peninsula. Antarctic microbial ecology
(Doctoral thesis, 2010-06-22)The waters surrounding the South Shetland Islands, Antarctica, comprise a coastal/oceanic ecosystem that is iron-fertilized naturally from shelf sources of Weddell Sea origin. My thesis incorporates data from an 18-year ... -
Quantitative molecular detection of larval Atlantic herring (Clupea harengus) in stomach contents of Atlantic mackerel (Scomber scombrus) marks regions of predation pressure
(Journal article; Peer reviewed, 2021)Mortality rates in the early life-history stages of fishes are generally high yet identifying the causes remain unclear. Faltering recruitment rates of Atlantic herring (Clupea harengus) in the Norwegian Sea indicate a ... -
