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 ... -
Seasonal and diel variation in greenhouse gas emissions from an urbanpond and its major drivers
(Peer reviewed; Journal article, 2019-09)Small water systems are important hotspots of greenhouse gas (GHG) emission, but estimates are poorly constrained as data are scarce. Small ponds are often constructed in urban areas, where they receive large amounts of ... -
Seasonal Changes in Photoperiod: Effects on Growth and Redox Signaling Patterns in Atlantic Salmon Postsmolts
(Journal article; Peer reviewed, 2023)Farmed Atlantic salmon reared under natural seasonal changes in sea-cages had an elevated consumption of antioxidants during spring. It is, however, unclear if this response was caused by the increase in day length, ... -
The seasonal cycle in the Atlantic transport to the Barents Sea during the years 1997–2001
(Peer reviewed; Journal article, 2004)The seasonal cycle in the Atlantic inflow to the Barents Sea is investigated by using 4-year long records from moored current meters, additional moorings of shorter duration, and hydrographic measurements. A higher transport ... -
Seasonal diversity and dynamics of haptophytes in the Skagerrak, Norway, explored by high-throughput sequencing
(Peer reviewed; Journal article, 2015-06)Microalgae in the division Haptophyta play key roles in the marine ecosystem and in global biogeochemical processes. Despite their ecological importance, knowledge on seasonal dynamics, community composition and abundance ... -
Seasonal dynamics and life histories of three sympatric species of Pseudocalanus in two Svalbard fjords
(Journal article; Peer reviewed, 2021)Small copepods are the most diverse and numerous group in high-latitude zooplankton, yet our knowledge of important species remains poor because of the difficulties involved in correct species identification. In this study, ... -
Seasonal dynamics of algae-infecting viruses and their inferred interactions with protists
(Peer reviewed; Journal article, 2019-11-09)Viruses are a highly abundant, dynamic, and diverse component of planktonic communities that have key roles in marine ecosystems. We aimed to reveal the diversity and dynamics of marine large dsDNA viruses infecting algae ... -
Seasonal dynamics of atlantic herring (Clupea harengus L.) populations spawning in the vicinity of marginal habitats
(Peer reviewed; Journal article, 2014-11-05)Gillnet sampling and analyses of otolith shape, vertebral count and growth indicated the presence of three putative Atlantic herring (Clupea harengus L.) populations mixing together over the spawning season February–June ... -
Seasonal dynamics of bacterial biofilms on the kelp Laminaria hyperborea
(Peer reviewed; Journal article, 2010-05)Seasonal variations of the cell density and bacterial community composition in biofilms growing on the surface of the kelp Laminaria hyperborea from 2 sites on the southwestern coast of Norway were investigated using total ... -
Seasonal dynamics of haptophytes and dsDNA algal viruses suggest complex virus-host relationship
(Peer reviewed; Journal article, 2017-04-20)Viruses influence the ecology and diversity of phytoplankton in the ocean. Most studies of phytoplankton host–virus interactions have focused on bloom-forming species like Emiliania huxleyi or Phaeocystis spp. The role of ... -
Seasonal dynamics of the vertical migration behaviour of mesopelagic fish
(Doctoral thesis, 2010-11-26)This thesis focuses on the behavioural dynamics of mesopelagic fish in a fjordic environment. Acoustic data recorded with a stationary echosounder was used to primarily investigate the diel vertical migration behaviour of ... -
Seasonal pollutant levels in littoral high-Arctic amphipods in relation to food sources and terrestrial run-off
(Journal article; Peer reviewed, 2022)Increasing terrestrial run-off from melting glaciers and thawing permafrost to Arctic coastal areas is expected to facilitate re-mobilization of stored legacy persistent organic pollutants (POPs) and mercury (Hg), potentially ... -
