Study of Ecdysone receptor and Ultraspiracle in the salmon louse (Lepeophtheirus salmonis)
(Master thesis, 2015-05-31)The salmon louse (Lepeophtheirus salmonis) is a parasite living on mucus, skin and blood of salmonids fishes. L. salmonis causes lesions and infections on fish fins and skins and such physical damages often lead to other ... -
Studying the waste recycling potential of naturally occurring polychaetes on benthic trays under a Norwegian fish farm
(Master thesis, 2018-06-26)With an increasing salmon industry comes an increasing amount of waste released into the environment, impacting benthic environments in particular. This study investigated the potential of utilizing naturally occurring ... -
Sub-populations of coastal cod with different behaviour and life-history strategies
(Peer reviewed; Journal article, 2004-02-19)This study provides evidence of countergradient variations in life-history traits among coastal cod Gadus morhua off the Norwegian coast, suggesting the existence of sub-populations. One-yr-old wild-caught individuals from ... -
Substituted Two- To Five-Ring Polycyclic Aromatic Compounds Are Potent Agonists of Atlantic Cod (Gadus morhua) Aryl Hydrocarbon Receptors Ahr1a and Ahr2a
(Journal article; Peer reviewed, 2021)Polycyclic aromatic hydrocarbons (PAHs) are among the most toxic and bioavailable components found in petroleum and represent a high risk to aquatic organisms. The aryl hydrocarbon receptor (Ahr) is a ligand-activated ... -
Suicidality among children and youth in Nordic child welfare services: A systematic review
(Journal article; Peer reviewed, 2021)Existing research has established child welfare (CW) clients as a vulnerable group for developing negative life trajectories, including mental health problems, work- and education-related challenges and premature mortality. ... -
Sulfate homeostasis in Atlantic salmon is associated with differential regulation of salmonid-specific paralogs in gill and kidney
(Journal article; Peer reviewed, 2021)Sulfate (SO2−4) regulation is challenging for euryhaline species as they deal with large fluctuations of SO2−4 during migratory transitions between freshwater (FW) and seawater (SW), while maintaining a stable plasma SO2−4 ... -
SulfoSYS (Sulfolobus Systems Biology): towards a silicon cell model for the central carbohydrate metabolism of the archaeon Sulfolobus solfataricus under temperature variation
(Peer reviewed; Journal article, 2009)SulfoSYS (Sulfolobus Systems Biology) focuses on the study of the CCM (central carbohydrate metabolism) of Sulfolobus solfataricus and its regulation under temperature variation at the systems level. In Archaea, carbohydrates ... -
The summer bacterial and archaeal community composition of the northern Barents Sea
(Journal article; Peer reviewed, 2023)Climate change related alterations in the Arctic have influences on the marine ecosystems, in particular on phytoplankton bloom dynamics. Since phytoplankton blooms are the main provider of carbon sources to the microbial ... -
Summer distribution and demography of Antarctic krill Euphausia superba Dana, 1852 (Euphausiacea) at the South Orkney Islands, 2011–2015
(Peer reviewed; Journal article, 2018-11-22)We carried out a survey of Antarctic krill (Euphausia superbaDana, 1850) from 2011 to 2015 to establish a long-term, time-series dataset of distribution, abundance, and demography for this species in the South Orkney Islands ... -
Surface environment modification in Atlantic salmon sea-cages: Effects on amoebic gill disease, salmon lice, growth and welfare
(Peer reviewed; Journal article, 2018)Surface environment modification is a potential parasite control strategy in Atlantic salmon sea-cage farming. For instance, a temporary low salinity surface layer in commercial-scale snorkel sea-cages has coincided with ... -
Survival and injuries of cod, haddock and saithe that escape through codends and sorting grids in a commercial fishery

Survival of Salmonid Alphavirus in seawater under different physical conditions
(Master thesis, 2014-08-06)Pancreas disease (PD) is an infectious disease caused by Salmonid alphavirus (SAV), which infects Atlantic salmon, Salmo salar L., and rainbow trout, Oncorhynchus mykiss (Walbaum). PD causes substantial economical losses ... -
“Sustainability is not a vegan coffee shop.” Eliciting citizen attitudes and perspectives to localize the UN sustainable development goals
(Journal article; Peer reviewed, 2023)Integrating the United Nations Sustainable Development Goals (SDGs) into national legislation includes a need for their localization. The authors posit that this concept of localizing the SDGs is achieved if the goals are ... -
Sustainable fishing of inland waters
(Peer reviewed; Journal article, 2014-04-08)Sustainability in fisheries has over the past decades evolved from a single species maximization concept to covering ecosystem and biodiversity considerations. This expansion of the notion, together with increased evidence ... -
Sverdrup critical depth and the role of water clarity in Norwegian Coastal Water
(Peer reviewed; Journal article, 2015-02-25)The critical depth concept was first recognized by Gran and Braarud (1935). During summer, in the Bay of Fundy, they observed an unexpected no bloom situation. Their interpretation was that high amounts of detritus of ... -
Swimming with the fishes: validating drift diving to identify farmed Atlantic salmon escapees in the wild
(Peer reviewed; Journal article, 2019)Escaped farmed Atlantic salmon Salmo salar interbreeding with wild conspecifics represents a threat to the genetic integrity and viability of wild populations. Therefore, it is necessary to accurately quantify escapees in ... -
Switching of INCENP paralogs controls transitions in mitotic chromosomal passenger complex functions
(Peer reviewed; Journal article, 2019)A single inner centromere protein (INCENP) found throughout eukaryotes modulates Aurora B kinase activity and chromosomal passenger complex (CPC) localization, which is essential for timely mitotic progression. It has been ... -
Synechococcus in the Atlantic Gateway to the Arctic Ocean
(Peer reviewed; Journal article, 2016-10-05)Increasing temperatures, with pronounced effects at high latitudes, have raised questions about potential changes in species composition, as well as possible increased importance of small-celled phytoplankton in marine ... -
