Multiple Aeromonas strains isolated from Atlantic salmon (Salmo salar) displaying red skin disease signs in Scandinavian rivers
(Journal article; Peer reviewed, 2023)Since 2014, Atlantic salmon (Salmo salar L.) displaying clinical signs of red skin disease (RSD), including haemorrhagic and ulcerative skin lesions, have been repeatedly observed in Swedish rivers. Although the disease ... -
Aquaculture-driven evolution of the salmon louse mtDNA genome
(Journal article; Peer reviewed, 2023)Resistance toward the antiparasitic pyrethroid, deltamethrin, is reported in the Atlantic salmon louse (Lepeophtheirus salmonis salmonis), a persistent ectoparasite of farmed and wild salmonids. The resistance mechanism ... -
The Distribution of IgT mRNA+ Cells in the Gut of the Atlantic Salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2023)The newly discovered IgT+ B cell is thought to play a dominant role in mucosal immunity, but limited studies have examined its distribution in fish species, hindering our understanding of its function. This study investigated ... -
Growth Performance, Nutrient Digestibility, and Retention in Atlantic Salmon, Salmo salar L., Fed Diets with Fermented Sugar Kelp, Saccharina latissima
(Journal article; Peer reviewed, 2023)Using low trophic marine resources such as sugar kelp (Saccharina latissimi) is of great interest to increase the circular food production in the ocean. Sugar kelp does, however, contain high levels of carbohydrates and ... -
Digestibility and functionality of black soldier fly larvae meal in Atlantic salmon feeds
(Doctoral thesis, 2024-02-09)Fordøyeligheten og funksjonaliteten til delvis avfettet mel av svarte soldatfluelarver (BSFL) er studert i fôret til atlantisk laks (Salmo salar). Insektmel er et lovende alternativ til konvensjonelle fôringredienser på ... -
Diurnal temperature range as a key predictor of plants’ elevation ranges globally
(Journal article; Peer reviewed, 2023)A prominent hypothesis in ecology is that larger species ranges are found in more variable climates because species develop broader environmental tolerances, predicting a positive range size-temperature variability ... -
Model of mesopelagic fish predation on eggs and larvae shows benefits of tuna spawning under full moon
(Journal article; Peer reviewed, 2023)Most mesopelagic fish are small planktivores that migrate up at nightfall to feed in the safety of darkness and descend to depth at dawn to escape visual predators. However, the trophic roles can reverse since mesopelagic ... -
Evolutionary responses of Atlantic cod (Gadus morhua) to concurrent fisheries and climate stressors
(Doctoral thesis, 2024-02-08)Evolutionære ændringer i fisk er efterhånden en anderkendt sandhed, især på grund af forskning i fiskeri-induceret evolution siden 1970'erne. Vi ser især disse ændringer påvirke individuelle livshistorier, resulterende i ... -
Flower morphology variation in five species of Penstemon (Plantaginaceae) displaying Hymenoptera pollination syndrome
(Journal article; Peer reviewed, 2023)Background: Geographic distance promotes phenotypic variation by facilitating environmental distance, limiting gene flow, and exposing plants to different pollen vectors. Therefore, understanding how plant morphology changes ... -
Identification and characterization of two salmon louse heme peroxidases and their potential as vaccine antigens
(Journal article; Peer reviewed, 2023)Salmon louse, Lepeophtheirus salmonis, represents major challenge for salmon farming. Current treatments impose welfare issues and are costly, whereas prophylactic measures are unavailable. Two salmon louse heme peroxidases ... -
Transcriptome-wide analyses of early immune responses in lumpfish leukocytes upon stimulation with poly(I:C)
(Journal article; Peer reviewed, 2023)Background: Both bacterial and viral diseases are a major threat to farmed fish. As the antiviral immune mechanisms in lumpfish (Cyclopterus lumpus L.) are poorly understood, lumpfish leukocytes were stimulated with ... -
Progressive Motor and Non-Motor Symptoms in Park7 Knockout Zebrafish
(Journal article; Peer reviewed, 2023)DJ-1 is a redox sensitive protein with a wide range of functions related to oxidative stress protection. Mutations in the park7 gene, which codes for DJ-1 are associated with early onset familial Parkinson’s disease and ... -
An Arctic natural oil seep investigated from space to the seafloor
(Journal article; Peer reviewed, 2023)Due to climate change, decreasing ice cover and increasing industrial activities, Arctic marine ecosystems are expected to face higher levels of anthropogenic stress. To sustain healthy and productive ocean ecosystems, it ... -
Evolutionary, comparative, and functional analyses of STATs and regulation of the JAK-STAT pathway in lumpfish upon bacterial and poly(I:C) exposure
(Journal article; Peer reviewed, 2023)Background: The Janus kinase/signal transducers and activators of transcription (JAK-STAT) system regulates several biological processes by affecting transcription of genes as a response to cytokines and growth factors. ... -
Investigating the Versatility of a Flavin-containing Monooxygenase Engineered Towards Trimethylamine Conversion in Fish Protein Hydrolysate
(Master thesis, 2023-11-20)Byproducts from the seafood industry are rich in nutrients, such as peptides, which might be utilized to a greater extent in the food market. Peptides can be extracted from fish byproducts by enzymatic hydrolysis, but the ... -
Development of the adaptive immune system in ballan wrasse (Labrus bergylta) and the impact of different start-feed diets
(Doctoral thesis, 2024-01-19)Berggylt (Labrus bergylta) spiser hovedsakelig bløtdyr, pigghuder og krepsdyr, der også ektoparasitter som plukkes fra andre fisker kan nyttes. Denne egenskapen har ført til at berggylt nå er brukt som rensefisk innen ... -
Bryophytes dominate plant regulation of soil microclimate in alpine grasslands
(Journal article; Peer reviewed, 2023)Soil temperature and moisture are important regulators of a broad range of biotic and abiotic processes in terrestrial ecosystems. Vegetation can, in turn, play a role in regulating soil microclimate, which creates potential ... -
Glacier retreat alters downstream fjord ecosystem structure and function in Greenland
(Journal article; Peer reviewed, 2023)The melting of the Greenland Ice Sheet is accelerating, with glaciers shifting from marine to land termination and potential consequences for fjord ecosystems downstream. Monthly samples in 2016 in two fjords in southwest ... -
How to obtain clear images from in-trawl cameras near the seabed? A case study from the Barents Sea demersal fishing grounds
