Does vaterite otolith deformation affect post-release survival and predation susceptibility of hatchery-reared juvenile Atlantic Salmon?
(Journal article; Peer reviewed, 2021)Sagittal otoliths are calcareous structures in the inner ear of fishes involved in hearing and balance. They are usually composed of aragonite; however, aragonite can be replaced by vaterite, a deformity which is more ... -
Domesticated escapees on the run: The second-generation monitoring programme reports the numbers and proportions of farmed Atlantic salmon in >200 Norwegian rivers annually
(Peer reviewed; Journal article, 2019)Norway is the world’s largest producer of farmed Atlantic salmon and is home to ∼400 rivers containing wild salmon populations. Farmed escapees, a reoccurring challenge of all cage-based marine aquaculture, pose a threat ... -
Domestication-induced reduction in eye size revealed in multiple common garden experiments: The case of Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2021)Domestication leads to changes in traits that are under directional selection in breeding programmes, though unintentional changes in nonproduction traits can also arise. In offspring of escaping fish and any hybrid progeny, ... -
Dominating sublittoral fish species in a west Norwegian fjord and their trophic links to cod (Gadus morhua L.)
(Peer reviewed; Journal article, 1993)The fish fauna in the sublittoral habitat of Masfjorden, western Norway, has been studied in order to reveal survival and growth prospects of released juvenile cod in a large-scale stock enhancement experiment. Seasonal ... -
Downregulation of N-terminal acetylation triggers ABA-mediated drought responses in Arabidopsis
(Peer reviewed; Journal article, 2015-07-17)N-terminal acetylation (NTA) catalysed by N-terminal acetyltransferases (Nats) is among the most common protein modifications in eukaryotes, but its significance is still enigmatic. Here we characterize the plant NatA ... -

(Peer reviewed; Journal article, 2015-03-05)"Candidatus Methylacidiphilum kamchatkense" strain Kam1 is an aerobic methane-oxidizing thermoacidophilic bacterium belonging to the Verrucomicrobia phylum. It was recovered from an acidic geothermal site in Uzon Caldera, ... -
Draft Genome Sequence of Escherichia coli Strain Tj, Isolated from the Varzob River in Tajikistan
(Journal article, 2020)The 4.6-Mbp draft genome sequence of Escherichia coli strain Tj, isolated from the Varzob River in Tajikistan, is presented. This strain possesses four prophage elements related to Shigella phage SfV, E. coli O157:H7-specific ... -
Draft Genome Sequence of Thermus scotoductus Strain K1, Isolated from a Geothermal Spring in Karvachar, Nagorno Karabakh
(Peer reviewed; Journal article, 2015-11-12)The 2,379,636-bp draft genome sequence of Thermus scotoductus strain K1, isolated from geothermal spring outlet located in the Karvachar region in Nagorno Karabakh is presented. Strain K1 shares about 80% genome sequence ... -
Drivers of Megabenthic Community Structure in One of the World’s Deepest Silled-Fjords, Sognefjord (Western Norway)
(Journal article; Peer reviewed, 2020-06-09)The Sognefjord is the longest (205 km) and deepest (1308 m) fjord in Norway, and the second-longest in the world. Coast-fjord exchange in Sognefjord is limited by a seaward sill at 170 m water depth, which causes a clear ... -
Drivers of spatial variability in spring bloom onset and magnitude along a latitudinal gradient in the Nordic Seas
(Master thesis, 2018-06-21)Spring phytoplankton blooms in the Nordic Seas contribute a large proportion of global primary production, and their timing and magnitude heavily impacts higher trophic levels. Two key drivers of bloom development, ... -
Drivers of variation in the predator-prey interaction between cod and capelin in the Barents Sea
(Doctoral thesis, 2019-05-27)Cod (Gadus morhua) and capelin (Mallotus villosus) are commercially important species with key roles in the Barents Sea ecosystem. Cod is a major predator on capelin, and fluctuations in the capelin stock has influenced ... -
Driving forces in the distributions of the three most common deep-water coral species in Norway: Lophelia pertusa, Paragorgia arborea, and Primnoa resedaeformis
(Master thesis, 2017-12-20)This thesis explores a set of environmental variables may be used to predict the spatial distribution of the three most common cold-water coral (CWC) species in Norway: Lophelia pertusa, Paragorgia arborea, and Primnoa ... -
Duration of the parasitic phase determines subsequent performance in juvenile freshwater pearl mussels (Margaritifera margaritifera)
(Peer reviewed; Journal article, 2017-03)Host–parasite systems have been useful in understanding coevolutionary patterns in sympatric species. Based on the exceptional interaction of the long‐lived and highly host‐specific freshwater pearl mussel (FPM; Margaritifera ... -
Dying for change: A roadmap to refine the fish acute toxicity test after 40 years of applying a lethal endpoint
(Journal article; Peer reviewed, 2021)The fish acute toxicity test (TG203; OECD, 2019) is frequently used and highly embedded in hazard and risk assessment globally. The test estimates the concentration of a chemical that kills 50% of the fish (LC50) over a ... -
Dying from the lesser of three evils: facilitation and non-consumptive effects emerge in a model with multiple predators
(Peer reviewed; Journal article, 2019)Prey modify their behaviour to avoid predation, but dilemmas arise when predators vary in hunting style. Behaviours that successfully evade one predator sometimes facilitate exposure to another predator, forcing the prey ... -
Dynamic morphometrics of mucous cells reveal the minimal impact of therapeutic doses of peracetic acid on Atlantic salmon gill health
(Journal article; Peer reviewed, 2021)Mucous cells, the microscopic structural hallmark of mucosal surfaces, are highly responsive to environmental changes. Here we report how the gills of Atlantic salmon (Salmo salar) responded to peracetic acid (PAA), a ... -
Dynamic regulation of the transcription initiation landscape at single nucleotide resolution during vertebrate embryogenesis
