An amphipathic helix in Brl1 is required for nuclear pore complex biogenesis in S. cerevisiae
(Journal article; Peer reviewed, 2022)The nuclear pore complex (NPC) is the central portal for macromolecular exchange between the nucleus and cytoplasm. In all eukaryotes, NPCs assemble into an intact nuclear envelope (NE) during interphase, but the process ... -
Biodiversity, environmental drivers, and sustainability of the global deep-sea sponge microbiome
(Journal article; Peer reviewed, 2022)In the deep ocean symbioses between microbes and invertebrates are emerging as key drivers of ecosystem health and services. We present a large-scale analysis of microbial diversity in deep-sea sponges (Porifera) from ... -
Neutrophils in Atlantic salmon (Salmo salar L.) are MHC class II+ and secret IL-12p40 upon bacterial exposure
(Journal article; Peer reviewed, 2022)Antigen-presentation via major histocompatibility complex (MHC) to T cells is the key event to initiate adaptive immune responses. In teleosts, as in mammals, the main types of professional antigen-presenting cells (APCs) ... -
Cooperation between subcellular NAD pools in the maintenance of NAD-dependent processes
(Doctoral thesis, 2018-10-31)Nicotinamide adenine dinucleotide (NAD) is needed as a cofactor in several processes throughout the cell, and its availability is decisive for the activity of many NAD-dependent enzymes. Owing to the membrane barriers in ... -
Koprofile discomycetar (Ascomycetes : Discomycetes operculati = Pezizales) i Noreg : med særleg vekt på innsamling i Hordaland og Sogn og Fjordane
(Master thesis, 1978)Det er tilsaman omtala 51 koprofile discomycet-arter fordelt på 15 slekter i denne oppgåva. Av desse er 3 slekter nye for Noreg: Ascodesmis, Ascozonus og Coprotus. Dessutan er fylgjande 26 arter funne nye for Noreg: Ascobolus ... -
Comparing Body Density of Lumpfish (Cyclopterus lumpus) to Different Operational Welfare Indicators
(Journal article; Peer reviewed, 2022)Farmed lumpfish (Cyclopterus lumpus) are commonly used as cleaner fish in the salmonid aquaculture industry, but a knowledge gap exists with regards to their body density. Filling this knowledge gap is of importance, as ... -
Norovirus in Pacific Oysters : Insights into Molecular Viability Assays and Mitigation Strategies to Improve Food Safety
(Doctoral thesis, 2022-11-21)Som en av de vanligste årsakene til gastroenteritt, har norovirus (NoV) vært en belastning for pasienter, helsemyndigheter og samfunnet over hele verden. Patogenet overføres gjennom inntak av infektive viruspartikler. Mange ... -
Intracellular trafficking of fatty acids in the fish intestinal epithelial cell line RTgutGC
(Journal article; Peer reviewed, 2022-09-29)The shift towards higher inclusion of vegetable oils (VOs) in aquafeeds has resulted in major changes in dietary fatty acid composition, especially increased amounts of monounsaturated fatty acids (MUFAs) and decreased ... -
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 ... -
Basic mechanisms for control of appetite and feed intake in Atlantic salmon (Salmo salar)
(Doctoral thesis, 2022-11-10)Atlantisk laks (Salmo salar L.) er en nøkkelart i norsk sjømateksport, og representerer 70 – 80 Mrd NOK i verdi. Den store økningen i produksjon kombinert med overfôring har bidratt til negative effekter på det marine ... -
Multidisciplinary perspectives on living marine resources in the Arctic
(Journal article; Peer reviewed, 2022)Many areas in the Arctic are vulnerable to the impacts of climate change. We observe large-scale effects on physical, biological, economic and social parameters, including ice cover, species distributions, economic activity ... -
Genomic evidence of recent European introgression into North American farmed and wild Atlantic salmon
(Journal article; Peer reviewed, 2022)Gene flow between wild and domestic populations has been repeatedly demonstrated across a diverse range of taxa. Ultimately, the genetic impacts of gene flow from domestic into wild populations depend both on the degree ... -
Photo-enhanced toxicity of crude oil on early developmental stages of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2022)Photo-enhanced toxicity of crude oil is produced by exposure to ultraviolet (UV) radiation. Atlantic cod (Gadus morhua) embryos were exposed to crude oil with and without UV radiation (290–400 nm) from 3 days post fertilization ... -
Tuning and Development of an Individual-Based Model of the Herring Spawning Migration
(Journal article; Peer reviewed, 2022-01-13)Norwegian spring spawning herring is a migratory pelagic fish stock that seasonally navigates between distant locations in the Norwegian Sea. The spawning migration takes place between late winter and early spring. In this ... -
Metabolic rates, feed intake, appetite control, and gut transit of clownfish Amphiprion ocellaris exposed to increased temperature and limited feed availability
(Journal article; Peer reviewed, 2022)Episodes of elevated temperature, combined with lower feed availability, are among the predicted scenarios of climate change representing a challenge for coral reef fish. We investigated the response of clownfish (Amphiprion ... -
An ecosystem-scale litter and microplastics monitoring plan under the Arctic Monitoring and Assessment Programme (AMAP)
(Journal article; Peer reviewed, 2022)Lack of knowledge on levels and trends of litter and microplastics in the Arctic, is limiting our understanding of the sources, transport, fate, and effects is hampering global activities aimed at reducing litter and ... -
The power of multi-matrix monitoring in the Pan-Arctic region: plastics in water and sediment
(Journal article; Peer reviewed, 2022)Litter and microplastic assessments are being carried out worldwide. Arctic ecosystems are no exception and plastic pollution is high on the Arctic Council's agenda. Water and sediment have been identified as two of the ... -
Understanding climate change impacts on biome and plant distributions in the Andes: Challenges and opportunities
(Journal article; Peer reviewed, 2022)Aim: Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the ... -
Acoustic Delicing of Atlantic Salmon (Salmo salar): Fish Welfare and Salmon Lice (Lepeophtheirus salmonis) Dynamics
(Journal article; Peer reviewed, 2022)Acoustic lice treatment (AcuLice) is a newly developed system, which uses a composite acoustic sound image with low-frequency sound to remove salmon lice (Lepeophtheirus salmonis) from Atlantic salmon (Salmo salar). This ... -
Increasing temperature and prey availability affect the growth and swimming kinematics of Atlantic herring (Clupea harengus) larvae
