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 ... -
The effects of stream channelization on salmonid habitats in western Norway
(Master thesis, 2023-11-20)Amidst the Anthropocene era’s heightened human influence on the environment and escalating habitat degradation, this study delves into the impacts of channelization on salmon and sea trout habitats in small streams in ... -
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 ... -
Tilrettelegging for elever med lese- og skrivevansker under praktisk arbeid i biologi. En kvalitativ studie av læreres kunnskaper om og tilrettelegging for elever med lese- og skrivevansker under praktisk arbeid i biologi i videregående skole
(Master thesis, 2023-11-20)Biologifaget inneholder abstrakte og komplekse prosesser og teorier som kan føre til vanskeligheter med å tilegne seg kunnskapen særlig for dem som har lese- og skrivevansker. Praktisk arbeid kan være spesielt viktig fordi ... -
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 ... -
The effect of high and low particle load on smoltification of Atlantic Salmon (Salmo salar) in RAS
(Master thesis, 2023)This study explores the effect of high and low Total Suspended Solids (TSS) on smoltification, and ion regulation of Atlantic salmon (Salmo salar) reared in a Recirculating Aquaculture System (RAS). As the salmon aquaculture ... -
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
(Journal article; Peer reviewed, 2023)Underwater camera systems are commonly used for monitoring fish and fishing gear behaviours. More recently, camera systems have been applied to scientific trawl surveys for improved spatial resolution and less invasive ... -
The Fish Pathogen "Candidatus Clavichlamydia salmonicola" - A Missing Link in the Evolution of Chlamydial Pathogens of Humans
(Journal article; Peer reviewed, 2023)Chlamydiae like Chlamydia trachomatis and Chlamydia psittaci are well-known human and animal pathogens. Yet, the chlamydiae are a much larger group of evolutionary ancient obligate intracellular bacteria that includes ... -
Neurohypophysial and paracrine vasopressinergic signaling regulates aquaporin trafficking to hydrate marine teleost oocytes
(Journal article; Peer reviewed, 2023)The dual aquaporin (Aqp1ab1/Aqp1ab2)-mediated hydration of marine teleost eggs, which occurs during oocyte meiosis resumption (maturation), is considered a key adaptation underpinning their evolutionary success in the ... -
Adferd som stressmål: Atlantisk laks under fluktuerende temperaturregime.
(Master thesis, 2013-07-09)SAMMENDRAG Stressresponser hos fisk blir tradisjonelt målt med parametre som kortisolkonsentrasjon og fôrkonsum som gir mål på stress og velferd. Det man mangler er gode mål på subtile stressreaksjoner og kunnskap om hvordan ... -
Approaches to pollen taxonomic harmonisation in Quaternary palynology
