Profiling DNA methylation patterns of zebrafish liver associated with parental high dietary arachidonic acid.
(Journal article; Peer reviewed, 2019)Diet has been shown to influence epigenetic key players, such as DNA methylation, which can regulate the gene expression potential in both parents and offspring. Diets enriched in omega-6 and deficient in omega-3 PUFAs ... -
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 ... -
Endogenous production of n-3 long-chain PUFA from first feeding and the influence of dietary linoleic acid and the α-linolenic:linoleic ratio in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2019)Atlantic salmon (Salmo salar) possess enzymes required for the endogenous biosynthesis of n-3 long-chain PUFA (LC-PUFA), EPA and DHA, from α-linolenic acid (ALA). Linoleic acid (LA) competes with ALA for LC-PUFA biosynthesis ... -
Broad-scale distribution of the winter protozooplankton community in the North Sea
(Journal article; Peer reviewed, 2018)Protozooplankton (PZP) (here size range: 12–200 μm) are rarely sampled over a broad scale, especially in ecosystem monitoring programs, despite their trophodynamic importance as grazers in the microbial loop and as prey ... -
Development of the salmon louse Lepeophtheirus salmonis parasitic stages in temperatures ranging from 3 to 24°C
(Peer reviewed; Journal article, 2019) -
Implications of tag positioning and performance on the analysis of cetacean movement
(Journal article; Peer reviewed, 2019)Background Satellite-linked animal-borne tags enable the study of free-ranging marine mammals. These tags can only transmit data while their antenna is above the surface for a sufficient amount of time. Thus, the position ... -
Tracing Mercury Pollution along the Norwegian Coast via Elemental, Speciation, and Isotopic Analysis of Liver and Muscle Tissue of Deep-Water Marine Fish (Brosme brosme)
(Journal article; Peer reviewed, 2019)Liver and muscle tissue of tusks (Brosme brosme) have been analyzed for their THg and MeHg concentrations and Hg isotopic signatures for tracing Hg pollution along the Norwegian coast. Clear differences between tissue types ... -
Effects of chitin synthesis inhibitor treatment on Lepeophtheirus salmonis (Copepoda, Caligidae) larvae
(Journal article; Peer reviewed, 2019)The salmon louse (Lepeophtheirus salmonis) is an ectoparasite infecting Atlantic salmon (Salmo salar), which causes substantial problems to the salmon aquaculture and threatens wild salmon. Chitin synthesis inhibitors ... -
Spawning energetics and otolith microchemistry provide insights into the stock structure of bonga shad Ethmalosa fimbriata
(Journal article; Peer reviewed, 2019)The gross energy content of spawning batches and the microchemistry of sagittal otoliths in individual female bonga shad Ethmalosa fimbriata were compared between contrasting sampling sites at the Senegalese southern coast ... -
The role of fish life histories in allometrically scaled food-web dynamics
(Journal article; Peer reviewed, 2019)Body size determines key ecological and evolutionary processes of organisms. Therefore, organisms undergo extensive shifts in resources, competitors, and predators as they grow in body size. While empirical and theoretical ... -
Recurrent convergent evolution at amino acid residue 261 in fish rhodopsin
(Journal article; Peer reviewed, 2019)The evolutionary process that occurs when a species colonizes a new environment provides an opportunity to explore the mechanisms underlying genetic adaptation, which is essential knowledge for understanding evolution and ... -
Currents on the northern shelf of the Yellow Sea
(Journal article; Peer reviewed, 2019)The currents of the northern shelf of the Yellow Sea are investigated using observations of current and hydrography and numerical current model results. The Regional Ocean Model System (ROMS) with a horizontal resolution ... -
Multi-decadal warming of Atlantic water and associated decline of dissolved oxygen in a deep fjord
(Journal article; Peer reviewed, 2019)Previous studies have shown decline in dissolved oxygen of the ocean basins. A hypothesis for this development is that ocean warming through increased stratification has caused reduced ventilation of the interior ocean. ... -
Effects of cholecystokinin (CCK) on gut motility in the stomachless fish ballan wrasse (Labrus bergylta)
(Journal article; Peer reviewed, 2019)Cholecystokinin (CCK) is well-known as a key hormone that inhibits stomach emptying and stimulates midgut motility in gastric species. However, the function of CCK related to gut motility in agastric fish, especially in ... -
Growth and metabolism of adult polar cod (Boreogadus saida) in response to dietary crude oil
(Journal article; Peer reviewed, 2019)The increasing human presence in the Arctic shelf seas, with the expansion of oil and gas industries and maritime shipping, poses a risk for Arctic marine organisms such as the key species polar cod (Boreogadus saida). The ... -
The β-oxidation pathway is downregulated during diapause termination in Calanus copepods
(Journal article; Peer reviewed, 2019)Calanus copepods are keystone species in marine ecosystems, mainly due to their high lipid content, which is a nutritious food source for e.g. juvenile fish. Accumulated lipids are catabolized to meet energy requirements ... -
Remineralization rate of terrestrial DOC as inferred from CO2 supersaturated coastal waters
(Journal article; Peer reviewed, 2019)Coastal seas receive large amounts of terrestrially derived organic carbon (OC). The fate of this carbon, and its impact on the marine environment, is however poorly understood. Here we combine underway CO2 partial pressure ... -
