SAF-A/hnRNP U binds polyphosphoinositides via a lysine rich polybasic motif located in the SAP domain
(Journal article; Peer reviewed, 2023)Polyphosphoinositides (PPIn) play essential functions as lipid signalling molecules and many of their functions have been elucidated in the cytoplasm. However, PPIn are also intranuclear where they contribute to chromatin ... -
Safety and Reverence: How Roman Catholic Liturgy Can Respond to the COVID-19 Pandemic
(Journal article; Peer reviewed, 2021)The current COVID-19 pandemic is a major challenge for many religious denominations. The Roman Catholic Church strongly depends on physical communal worship and sacraments. Disagreements grow concerning the best balance ... -
Safety assessment of the functional feed additive phenylcapsaicin in a commercial broiler diet
(Journal article; Peer reviewed, 2023)Introduction: Intestinal colonisation of Salmonella is a major concern in the poultry industry, and a low dose of the high-purity synthetic capsaicin analogue phenylcapsaicin (PheCap) has the potential to be a phytobiotic ... -
Salamonid alphavirus (SAV) - genetic characterisation of a new subtype, SAV3, and implementation of a novel diagnostic method
(Doctoral thesis, 2006-12-13) -
Salmon lice as models for understanding life history evolution of parasites under intensive farming
(Doctoral thesis, 2017-06-20)Human activities are drastically changing ecological conditions for living organisms and this leads to evolutionary changes. One example is the appearance and spread of resistance against drugs and antibiotics, but we also ... -
Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
(Peer reviewed; Journal article, 2019)Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters. Currently, the parasitic salmon ... -
Salmon lice survive the straight shooter: A commercial scale sea cage trial of laser delousing
(Journal article; Peer reviewed, 2020)Ectoparasitic salmon louse (Lepeophtheirus salmonis) infestations are costly for Atlantic salmon (Salmo salar) farmers in Norway. As a result, there is a strong desire for solutions to prevent and control infestations, and ... -
The salmon louse genome: Copepod features and parasitic adaptations
(Journal article; Peer reviewed, 2021)Copepods encompass numerous ecological roles including parasites, detrivores and phytoplankton grazers. Nonetheless, copepod genome assemblies remain scarce. Lepeophtheirus salmonis is an economically and ecologically ... -
Salmon louse labial gland enzymes: implications for host settlement and immune modulation
(Journal article; Peer reviewed, 2024)Salmon louse (Lepeophtheirus salmonis) is a skin- and blood-feeding ectoparasite, infesting salmonids. While feeding, labial gland proteins from the salmon louse may be deposited on the Atlantic salmon (Salmo salar) skin. ... -
The salmon louse larval black box: evaluating fecundity and enumerating planktonic stages with an aquaculture management perspective
(Doctoral thesis, 2022-06-17)Modern salmon aquaculture began in 1970 with the innovation of at-sea fish pens which precipitated a rapid growth in production. The expansion of the industry and increased number of farmed fish concentrated within the ... -
The salmon louse Lepeophtheirus salmonis (Copepoda: Caligidae) life cycle has only two chalimus stages
(Peer reviewed; Journal article, 2013-09-12)Each year the salmon louse (Lepeophtheirus salmonis Krøyer, 1838) causes multi-million dollar commercial losses to the salmon farming industry world-wide, and strict lice control regimes have been put in place to reduce ... -
Salmonid fish: model organisms to study cardiovascular morphogenesis in conjoined twins?
(Peer reviewed; Journal article, 2016-07-16)Background: There is a gap in knowledge regarding the cardiovascular system in fish conjoined twins, and regarding the cardiovascular morphogenesis of conjoined twins in general. We examined the cardiovascular system in a ... -
Sammenligning av to varianter av infeksiøs pankreasnekrose-virus – sekvensanalyser og immunresponser
(Master thesis, 2022-06-01)Virussykdommer har vært et stort problem i oppdrettsnæringen. Kunnskap om interaksjonene mellom virus og vert er viktig for å forstå hvordan virus kan gi sykdom, og hvilke mekanismer som spiller inn. Infeksiøs pankreasne ... -
Scaling laws in phytoplankton nutrient uptake affinity
(Peer reviewed; Journal article, 2016-03-11)Nutrient uptake affinity affects the competitive ability of microbial organisms at low nutrient concentrations. From the theory of diffusion limitation it follows that uptake affinity scales linearly with the cell radius. ... -
A scavenger receptor B (CD36)-like protein is a potential mediator of intestinal heme absorption in the hematophagous ectoparasite Lepeophtheirus salmonis
(Peer reviewed; Journal article, 2019-03-12)Intestinal absorption of heme has remained enigmatic for years, even though heme provides the most bioavailable form of iron. The salmon louse, Lepeophtheirus salmonis, is a heme auxotrophic ectoparasite feeding on large ... -
The Schizosaccharomyces pombe JmjC-protein, Msc1, prevents H2A.Z localization in centromeric and subtelomeric chromatin domains
(Peer reviewed; Journal article, 2009-11-13)Eukaryotic genomes are repetitively packaged into chromatin by nucleosomes, however they are regulated by the differences between nucleosomes, which establish various chromatin states. Local chromatin cues direct the ... -
Schooling dynamics of summertime migrating Northeast Atlantic mackerel (Scomber scombrus) in the Norwegian Sea using multibeam sonar
(Master thesis, 2013-05-31)Pelagic fish in the Norwegian Sea perform seasonal migrations from overwintering, via spawning, to feeding grounds. Northeast Atlantic (NEA) mackerel (Scomber scombrus) are highly migratory, fast- swimming, and an obligate ... -
Science, the endless frontier of regulatory capture
(Journal article; Peer reviewed, 2022)In this paper we explore five recent cases of regulatory capture in Europe and zoom in on a form of corporate penetration which is based on a strategic use of the image and legitimacy of science. We examine cases in which ... -
Scientific floras can be reliable sources for some trait data in a system with poor coverage in global trait databases
(Journal article; Peer reviewed, 2021)Aim Trait-based approaches are increasingly important in ecology and biogeography, but progress is often hampered by the availability of high-quality quantitative trait data collected in the field. Alternative sources of ... -
Sea-ice loss boosts visual search: fish foraging and changing pelagic interactions in polar oceans
(Peer reviewed; Journal article, 2017)Light is a central driver of biological processes and systems. Receding sea ice changes the lightscape of high-latitude oceans and more light will penetrate into the sea. This affects bottom-up control through primary ...
