Distribution of Kudoa thyrsites (Cnidaria, Myxozoa) myoliquefactive stages in Northeast Atlantic mackerel (Scomber scombrus) inferred from qPCR and histology
(Journal article; Peer reviewed, 2022)Kudoa thyrsites is a myxosporean parasite (Cnidaria, Myxozoa) that infects the skeletal and cardiac muscle of Northeast Atlantic (NEA) mackerel (Scomber scombrus). Heavy infections are associated with post-mortem myoliquefaction ... -
High abundances of small copepods early developmental stages and nauplii strengthen the perception of a non-dormant Arctic winter
(Journal article; Peer reviewed, 2022)The traditional view is that the Arctic polar night is a quiescent period for marine life, but recent reports of high levels of feeding and reproduction in both pelagic and benthic taxa have challenged this. We examined ... -
The Nuclear Pore Complex: Birth, Life, and Death of a Cellular Behemoth
(Journal article; Peer reviewed, 2022)Nuclear pore complexes (NPCs) are the only transport channels that cross the nuclear envelope. Constructed from ~500–1000 nucleoporin proteins each, they are among the largest macromolecular assemblies in eukaryotic cells. ... -
An EvoDevo Study of Salmonid Visual Opsin Dynamics and Photopigment Spectral Sensitivity
(Journal article; Peer reviewed, 2022)Salmonids are ideal models as many species follow a distinct developmental program from demersal eggs and a large yolk sac to hatching at an advanced developmental stage. Further, these economically important teleosts ... -
Genetic diversity, gene flow and hybridization in fan-shaped sponges (Phakellia spp.) in the North-East Atlantic deep sea
(Journal article; Peer reviewed, 2022)Deep-sea North Atlantic sponge grounds are crucial components of the marine fauna providing a key role in ecosystem functioning. To properly develop effective conservation and management plans, it is crucial to understand ... -
Time series covering up to four decades reveals major changes and drivers of marine growth and proportion of repeat spawners in an Atlantic salmon population
(Journal article; Peer reviewed, 2022)Wild Atlantic salmon populations have declined in many regions and are affected by diverse natural and anthropogenic factors. To facilitate management guidelines, precise knowledge of mechanisms driving population changes ... -
Insights into the genetic diversity, antibiotic resistance and pathogenic potential of Klebsiella pneumoniae from the Norwegian marine environment using whole-genome analysis
(Journal article; Peer reviewed, 2022)Klebsiella pneumoniae (Kp) can cause hospital- and community acquired infections. Although, Kp is widespread in the environment, very little is known about the genetic diversity and pathogenicity of Kp from the marine ... -
Diversified Farming Systems: Impacts and Adaptive Responses to the COVID-19 Pandemic in the United States, Norway and China
(Journal article; Peer reviewed, 2022)The COVID-19 pandemic fully exposed the vulnerability of the global agri-food system to shocks and stresses, highlighting the need for transformation and action to make it more resilient and inclusive. This paper offers a ... -
Introgression of domesticated salmon changes life history and phenology of a wild salmon population
(Journal article; Peer reviewed, 2022)The release of domesticated conspecifics into the natural environment, whether deliberate or accidental, has the potential to alter the genetic integrity and evolutionary trajectory of wild populations. This widespread ... -
Single PFAS and PFAS mixtures affect nuclear receptor- and oxidative stress-related pathways in precision-cut liver slices of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2022)The aim of the present study was to investigate effects of per- and polyfluoroalkyl substances (PFAS), both single compounds and a mixture of these, using precision-cut liver slices (PCLS) from Atlantic cod (Gadus morhua). ... -
Studenters opplevelse av meningsskapende samsvar
(Master thesis, 2022-06-01)Meningsskapende samsvar er en student-sentrert modell utviklet av pedagogen John Biggs, som hevdes å forbedre kvaliteten på læring og undervisning. Med et konstruktivistisk grunnsyn tar modellen sikte på å skape et samsvar ... -
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 ... -
Different production protocols influence smolt physiology and growth in seawater for Atlantic salmon (Salmo salar)

Aquaculture-driven evolution of the salmon louse (Lepeophtheirus salmonis) mtDNA genome
(Master thesis, 2022-06-01)Widespread resistance towards pyrethroids, a pesticide that has been extensively used in salmonid aquaculture to control sea lice, is reported in the salmon louse (Lepeophtheirus salmonis). The resistance mechanism has ... -
Long-term investigation of the ‘soft flesh’ condition in Northeast Atlantic mackerel induced by the myxosporean parasite Kudoa thyrsites (Cnidaria, Myxozoa): Temporal trends and new molecular epidemiological observations
(Journal article; Peer reviewed, 2022)Northeast Atlantic (NEA) mackerel (Scomber scombrus, Scombridae) represents an economically important target for the Norwegian pelagic fishing industry. Despite the commercial significance of NEA mackerel, little is known ... -
Escape- and diet-history among farmed Atlantic Salmon caught in Norwegian rivers and coast in the period 2011-2021
(Master thesis, 2022-06-01)Every year thousands of farmed Atlantic salmon (Salmo salar) escape from net pens in Norway, and introgression has been documented in two-thirds of the more than 200 wild populations investigated thus far. Farmed salmon ... -
Challenge model for Pasteurella atlantica genomovar salmonicida in Atlantic salmon (Salmo salar L.)
(Master thesis, 2022-06-01)Pasteurellose i Atlantisk laks (Salmo salar L.) har blitt et problem i Norge de siste årene. I fiskehelserapporten fra 2021 karakteriserte Veterinærinstituttet (VI) for første gang pasteurellose i Atlantisk laks som en ... -
Smittemodellutvikling for Pasteurella atlantica gv. salmonicida og Pasteurella skyensis hos Atlantisk laks (Salmo salar)
(Master thesis, 2022-06-01)De siste årene har pasteurellose blitt et tiltakende problem i lakseoppdrett langs vestlandskysten av Norge. Sykdommen er i de fleste tilfellene forårsaket av bakterien med arbeidsnomenklaturen Pasteurella atlantica gv. ... -
Habitat variability and faunal zonation at the Ægir Ridge, a canyon-like structure in the deep Norwegian Sea
(Journal article; Peer reviewed, 2022)The Ægir Ridge System (ARS) is an ancient extinct spreading axis in the Nordic seas extending from the upper slope east of Iceland (∼550 m depth), as part of its Exclusive Economic Zone (EEZ), to a depth of ∼3,800 m in the ... -
Biodiversity and spatial ecology of arctic sponge grounds in the Nordic Seas
