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 ... -
The impacts of urbanization on pollinator communities in Bergen, Norway
(Master thesis, 2023-11-27)This study was conducted in Bergen, Norway in 2022, whereas I investigated the underlying factors of pollinator abundance and the abundance and richness of Bombus (bumblebees). I explored pollinator communities across ... -
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 ... -
Virulence factors of Pasteurella atlantica genomovar salmonicida and effect on salmon leucocytes
(Master thesis, 2023-11-20) -
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. ... -
Exploring the Condition of Fish Welfare and Microbial Dynamics in Egget® – a Novel Closed Aquaculture System at Sea
(Master thesis, 2023-10-02)The Norwegian Atlantic salmon (Salmo salar) aquaculture industry faces significant challenges, prompting the need for innovative approaches to enhance sustainability. One such innovation is the prototype Egget®, a novel ... -
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 ... -
Vgll3 knockout as a means to delay male maturity during large smolt production of Atlantic salmon (Salmo salar L.)
(Master thesis, 2023-12-01)With a 100 billion NOK export value, Atlantic salmon (Salmo salar L.) has become one of the most important export products for Norway. A highly intensified production in recirculating aquaculture systems (RAS) has pushed ... -
