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 ... -

(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
(Journal article; Peer reviewed, 2024)The aim of this study was to evaluate whether sea lice grazing efficiency, behaviour, size variation and cataract development can be improved through selective breeding of lumpfish. A series of studies was conducted over ... -
Resurrection of genus Phocanema Myers, 1959, as a genus independent from Pseudoterranova Mozgovoĭ, 1953, for nematode species (Anisakidae) parasitic in pinnipeds and cetaceans, respectively
(Journal article; Peer reviewed, 2023)Species of the genus Pseudoterranova, infect kogiid cetaceans and pinnipeds. However, there is mounting molecular evidence that those from cetaceans and pinnipeds are not congeneric. Here, we provide further evidence of ... -
Utilizing multi-objective decision support tools for protected area selection
(Journal article; Peer reviewed, 2023)Establishing and maintaining protected areas (PAs) is a key action in delivering post-2020 biodiversity targets. PAs often need to meet multiple objectives, ranging from biodiversity protection to ecosystem service provision ... -
Genotyping tool for salmonid gill pox virus (SGPV) obtained from farmed and wild Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2023)Poxviruses are common viruses found in vertebrate species. In 2006, the first poxvirus associated with salmon, salmonid gill poxvirus (SGPV), was identified during an outbreak of gill disease at a smolt production site in ... -
“Why is this relevant for me?”: increasing content relevance enhances student motivation and vitality
(Journal article; Peer reviewed, 2023)The notion that motivation is imperative for students’ psychological well-being and academic functioning is central to Self-Determination Theory (SDT). According to SDT, different types of motivations can co-occur to a ... -
Gender and early career status: variables of participation at an international marine science conference
(Journal article; Peer reviewed, 2023)Conference participation is an important part of academic practice and contributes to building scientific careers. Investigating demographic differences in conference participation may reveal factors contributing to the ... -
Bootstrapping outperforms community-weighted approaches for estimating the shapes of phenotypic distributions
(Journal article; Peer reviewed, 2023)1. Estimating phenotypic distributions of populations and communities is central to many questions in ecology and evolution. These distributions can be characterized by their moments (mean, variance, skewness and kurtosis) ... -
Genomic Signatures of Local Adaptation under High Gene Flow in Lumpfish—Implications for Broodstock Provenance Sourcing and Larval Production
(Journal article; Peer reviewed, 2023-09-26)Aquaculture of the lumpfish (Cyclopterus lumpus L.) has become a large, lucrative industry owing to the escalating demand for “cleaner fish” to minimise sea lice infestations in Atlantic salmon mariculture farms. We used ... -
Nutrient use by tropical ant communities varies among three extensive elevational gradients: A cross-continental comparison
(Journal article; Peer reviewed, 2023)Aim: Many studies demonstrate that climate limits invertebrates along tropical elevational gradients, but we have only a rudimentary understanding of the role of nutrient limitation and climatic seasonality. Here we examined ... -
First identification of mycobacteriosis in Atlantic mackerel (Scomber scombrus)
(Journal article; Peer reviewed, 2023)Mycobacterium infection in fish is a well-known disease problem globally, mainly in the farming of ornamental fish or fish for food. Less is known about the prevalence, distribution and the effects such infections have on ... -
Seasonal Changes in Photoperiod: Effects on Growth and Redox Signaling Patterns in Atlantic Salmon Postsmolts
(Journal article; Peer reviewed, 2023)Farmed Atlantic salmon reared under natural seasonal changes in sea-cages had an elevated consumption of antioxidants during spring. It is, however, unclear if this response was caused by the increase in day length, ... -
Atlantic salmon male post-smolt maturation can be reduced by using a 3-hour scotophase when inducing smoltification
(Journal article; Peer reviewed, 2023)Photoperiod regulates the occurrence of unwanted male post-smolt maturation during the production of large (>100 g) Atlantic salmon (Salmo salar) smolts. However, the optimal daylength for triggering smoltification, but ... -
