Identification of housekeeping genes of Candidatus Branchiomonas cysticola associated with epitheliocystis in Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2022)Candidatus Branchiomonas cysticola is an intracellular, gram-negative Betaproteobacteria causing epitheliocystis in Atlantic Salmon (Salmo salar L.). The bacterium has not been genetically characterized at the intraspecific ... -
Role of Prdm genes in ectodermal and non-ectodermal neurogenesis in Nematostella vectensis
(Doctoral thesis, 2021-03-04)The origin and evolution of the nervous system is a long-standing question in biology to understand the complexity observed today. Developmentally, the nervous system arises from the outer germ layer: the ectoderm. ... -
Gaussian mixture models reveal highly diverse targeting tactics in a coastal fishing fleet
(Journal article; Peer reviewed, 2022)Fishermen make repeated choices with respect to when, where, and how to catch their target species. While these targeting tactics—and the factors shaping them—are known to fishers and some experts, knowledge about them is ... -
Multiomics in the central Arctic Ocean for benchmarking biodiversity change
(Journal article; Peer reviewed, 2022-10-17)Multiomics approaches need to be applied in the central Arctic Ocean to benchmark biodiversity change and to identify novel species and their genes. As part of MOSAiC, EcoOmics will therefore be essential for conservation ... -
Brachiopod and mollusc biomineralisation is a conserved process that was lost in the phoronid–bryozoan stem lineage
(Journal article; Peer reviewed, 2022-09-19)Background: Brachiopods and molluscs are lophotrochozoans with hard external shells which are often believed to have evolved convergently. While palaeontological data indicate that both groups are descended from biomineralising ... -
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
