Acoustic micronektonic distribution and density is structured by macroscale oceanographic processes across 17–48° N latitudes in the North Atlantic Ocean
(Peer reviewed; Journal article, 2023)This study investigates the large-scale distribution patterns of the acoustic scattering layers and micronekton density across the Northeast Atlantic Ocean during daylight hours. A research cruise on board R/V “Kronprins ... -
Adaptive photoperiod interpretation modulates phenological timing in Atlantic salmon
(Peer reviewed; Journal article, 2023)Photoperiod, the portion of 24-h cycle during which an organism is exposed to illumination, is an important phenological cue in many animals. However, despite its influence on critical biological processes, there remain ... -
Adipose MDM2 regulates systemic insulin sensitivity
(Peer reviewed; Journal article, 2021)The intimate association between obesity and type II diabetes urges for a deeper understanding of adipocyte function. We and others have previously delineated a role for the tumor suppressor p53 in adipocyte biology. Here, ... -
Algae associated with coral degradation affects risk assessment in coral reef fishes
(Journal article; Peer reviewed, 2017)Habitat degradation alters the chemical landscape through which information about community dynamics is transmitted. Olfactory information is crucial for risk assessment in aquatic organisms as predators release odours ... -
Atlantic salmon and sea trout display synchronised smolt migration relative to linked environmental cues
(Peer reviewed; Journal article, 2020)Anadromous salmon and sea trout smolts face challenging migrations from freshwater to the marine environment characterised by high mortality. Therefore, the timing of smolt migration is likely to be critical for survival. ... -
Autumn movements of fin whales (Balaenoptera physalus) from Svalbard, Norway, revealed by satellite tracking
(Peer reviewed; Journal article, 2020)Insight into animal movements is essential for understanding habitat use by individuals as well as population processes and species life-history strategies. In this study, we instrumented 25 fin whales with ARGOS ... -
Blood-based gene expression as non-lethal tool for inferring salinity-habitat history of European eel (Anguilla anguilla)
(Peer reviewed; Journal article, 2022)The European eel is a facultative catadromous species, meaning that it can skip the freshwater phase or move between marine and freshwater habitats during its continental life stage. Otolith microchemistry, used to determine ... -
Boat noise impacts risk assessment in a coral reef fish but effects depend on engine type
(Journal article; Peer reviewed, 2018)Human noise pollution has increased markedly since the start of industrialization and there is international concern about how this may impact wildlife. Here we determined whether real motorboat noise affected the behavior, ... -
Boreal marine fauna from the Barents sea disperse to Arctic Northeast Greenland
(Peer reviewed; Journal article, 2019)As a result of ocean warming, the species composition of the Arctic seas has begun to shift in a boreal direction. one ecosystem prone to fauna shifts is the Northeast Greenland shelf. the dispersal route taken by boreal ... -
Cascading effects of temperature alterations on trophic ecology of European grayling (Thymallus thymallus)
(Journal article; Peer reviewed, 2019)The aims of this project were to study: diet composition, food selectivity and the phenology of different prey items in grayling’s (Thymallus thymallus) diet. It was hypothesized, that alterations in mayfly emergence, ... -
Century-long cod otolith biochronology reveals individual growth plasticity in response to temperature
(Peer reviewed; Journal article, 2020)Otolith biochronologies combine growth records from individual fish to produce long-term growth sequences, which can help to disentangle individual from population-level responses to environmental variability. This study ... -
Characterization of Pseudoterranova ceticola (Nematoda: Anisakidae) larvae from meso/bathypelagic fishes off Macaronesia (NW Africa waters)
(Peer reviewed; Journal article, 2022)The genus Pseudoterranova includes parasite species of cetaceans and pinnipeds. The third stage larva (L3) of seal-infecting species occur in second intermediate or paratenic fish hosts mainly in neritic waters. This study ... -
Computer vision enables short- and long-term analysis of Lophelia pertusa polyp behaviour and colour from an underwater observatory
(Peer reviewed; Journal article, 2019)An array of sensors, including an HD camera mounted on a Fixed Underwater Observatory (FUO) were used to monitor a cold-water coral (Lophelia pertusa) reef in the Lofoten-Vesterålen area from April to November 2015. Image ... -
Contrasting effects of rising temperatures on trophic interactions in marine ecosystems
(Journal article; Peer reviewed, 2019)In high-latitude marine environments, primary producers and their consumers show seasonal peaks of abundance in response to annual light cycle, water column stability and nutrient availability. Predatory species have adapted ... -

CRISPR/Cas9-mediated ablation of elovl2 in Atlantic salmon (Salmo salar L.) inhibits elongation of polyunsaturated fatty acids and induces Srebp-1 and target genes
(Journal article; Peer reviewed, 2019)Atlantic salmon can synthesize polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (20:5n-3), arachidonic acid (20:4n-6) and docosahexaenoic acid (22:6n-3) via activities of very long chain fatty acyl elongases ... -
CRISPR/Cas9-mediated editing of Δ5 and Δ6 desaturases impairs Δ8-desaturation and docosahexaenoic acid synthesis in Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2019)The in vivo functions of Atlantic salmon fatty acyl desaturases (fads2), Δ6fads2-a, Δ6fads2-b, Δ6fads2-c and Δ5fads2 in long chain polyunsaturated fatty acid (LC-PUFA) synthesis in salmon and fish in general remains to be ... -
Cryptic introgression: evidence that selection and plasticity mask the full phenotypic potential of domesticated Atlantic salmon in the wild
(Journal article; Peer reviewed, 2018)Domesticated Atlantic salmon grow much faster than wild salmon when reared together in fish tanks under farming conditions (size ratios typically 1:2–3). In contrast, domesticated salmon only display marginally higher ... -
