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
(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 ... -
Approaches to pollen taxonomic harmonisation in Quaternary palynology
(Journal article; Peer reviewed, 2023)Pollen taxonomic harmonisation involves the standardisation of the nomenclature of pollen and fern spores with similar morphotypes at the determination level that is common to all grains or spores with that morphotype ... -
Secretory vesicle protein homologues in choanoflagellates
(Doctoral thesis, 2023-12-15)Regulert vesikeleksocytose, som i tilfellet med høyt spesialisert synaptisk vesikelsekresjon, styres av et sett evolusjonært konserverte proteiner. Mange av disse proteinene er eldre enn dyrene. Målet med denne avhandlingen ... -
At what cost? Attempting to quantify cost of resistance in bacterium-phage interactions
(Doctoral thesis, 2023-12-15)Biodiversiteten i mikrobielle samfunn er svært stor. Organismene som danner samfunnet må stadig gjøre avveininger mellom ulike karaktertrekk som påvirker deres muligheter for vekst, konkurranse og overlevelse. For å beskrive ... -
Localizing the United Nations Sustainable Development Goals in northern Norway: Transdisciplinary approaches for sustainable coastal development
(Doctoral thesis, 2023-12-01)I 2015 lanserte FN «2030 Agenda for Sustainable Development» med et unikt og ambisiøst rammeverk for global bærekraft som inkluderer 17 bærekraftsmål (SDG). Siden den gang har mange ledere over hele verden på lokalt, ... -
Evolutionary Origin and Developmental Relationships of Germline, Gonads, and Embryonic Mesodermal Precursors
(Doctoral thesis, 2023-11-15)Kjønnscellene, oocytter og sædceller, er essensielle celletyper for artsforplantning hos alle seksuelt reproduserende dyr. Differensiering av kjønnsceller kan skje via to ulike mekanismer: arv og induksjon. I denne oppgaven ... -
Elevated sea temperature combined with dietary methionine levels affect feed intake and appetite-related neuropeptide expression in the brains of juvenile cobia (Rachycentron canadum)
(Journal article; Peer reviewed, 2023-07-04)This study aimed to determine the impact of elevated temperature combined with different levels of dietary methionine concentrations on feed intake (FI) and brain expression of selected neuropeptides and one receptor ... -
Fine-scale spatial variation of northern shrimp and Atlantic cod across three Norwegian fjord systems and implications for management
(Journal article; Peer reviewed, 2023)The spatial complexity of coastal ecosystems represents a challenge for the management of inshore resources. Here we compared two large fjord systems in northern Norway that have been closed for all bottom trawling for 50 ... -
Organization, transformation, and activation of the melanocortin system in Atlantic salmon
(Doctoral thesis, 2023-11-03)Atlantisk laks (Salmo salar) er en nøkkelart i norsk havbruk. Det trengs imidlertid mer kunnskap og teknologi for å kontinuerlig utvikle mer bærekraftig produksjon, forbedre dyrevelferden og for å øke den økonomiske verdien ... -
Towards better lumpfish: Changes in size variation, cataract development, behaviour and sea lice grazing through selective breeding
