The microbiome of bioreactors containing mass-cultivated marine diatoms for industrial carbon capture and utilization
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-10)Marine microalgae are a promising innovation platform for carbon capture and utilization (CCU) biotechnologies to mitigate industrial greenhouse gas emissions. However, industrial-scale cultivation of algal mono-cultures is challenging and often unscalable. Non-axenic microalgae in large semi-open photobioreactors lead to the co-cultivation of diverse microbial communities. There is limited knowledge ... -
Tourism mobilities and climate crisis dilemmas: Tourists traveling towards a climate apocalypse?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-18)Framed by a multidimensional approach to dilemmas, this qualitative study focuses on Norwegians' views on tourism mobilities and climate change dilemmas, contextual aspects, coping strategies, and consequences. Despite being situated in ideological and moral landscapes where the climate crisis is largely ignored, all participants acknowledge the dilemmas. However, the unconcerned deny personal ... -
Sea ice as habitat for microalgae, bacteria, virus, fungi, meio- and macrofauna: A review of an extreme environment
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-30)The novel concept of the review is a focus on the organisms living in the sea ice and what mechanisms they have developed for their existence. The review describes the physical environment of the sea ice and the microorganisms living there as microalgae, bacteria, virus, fungi, meio- and macrofauna where they inhabit the brine channels and exposed to low temperatures as down to −25 °C and high ... -
Tanycytes from a bird’s eye view: gene expression profiling of the tanycytic region under different seasonal states in the Svalbard ptarmigan
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-20)In mammals and birds, tanycytes are known to regulate thyroid hormone conversion, and this process is central to the control of seasonal reproduction. In mammals, this cell type is also implicated in retinoic acid signalling, neurogenesis, and nutritional gatekeeping, all of which have been linked to hypothalamic regulation of energy metabolism. Less is known about these potential wider roles of ... -
Humour and comics for academic change and well-being
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-28)Considering recent calls for change towards a more liveable tourism academia, we combined critical participatory action research with duoethnography to develop The Academic Line—a humorous comic project about academic life. We used traditional theories of humour to leverage the effectiveness of comics as communicative devices and explored how and to what extent our project promoted solidarity, ... -
Clocks at a snail pace: biological rhythms in terrestrial gastropods
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-29)Biological rhythms are ubiquitous across the tree of life. Organisms must allocate their activities into moments of the day and of the season that will increase their probability of surviving and reproducing, which is done in the form of daily and annual rhythms. So far, the vast majority of studies on biological rhythms have focused on classical laboratory model species. Still, the use of ... -
Reproductive performance of lumpfish (Cyclopterus lumpus, L. 1758) females: Effects of integrated photoperiod and temperature manipulations on sexual maturation and spawning
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-15)A successful control of sexual maturation is crucial for year-round production of lumpfish juveniles destined as cleaner fish in Atlantic salmon aquaculture. This study investigated the combined effects of photoperiod and temperature manipulations on sexual maturation and spawning in lumpfish females. Lumpfish juveniles were exposed to simulated natural and nine-month compressed annual photoperiods, ... -
Rental expenses in private kindergartens: Impact of organizational structure on rental expenses in private kindergartens
(Master thesis; Mastergradsoppgave, 2024-06-03)Between 2019 and 2021, several major corporate groups within the kindergarten sector sold kindergarten properties to foreign private equity firms. As a result, affected kindergartens transitioned from property ownership to tenancy roles. This thesis aims to investigate the impact of organizational structure and ownership type on rental expenses within the private kindergarten sector in Norway. The ... -
Hvordan kan Hertz tilpasse seg og opprettholde konkurransekraft i møtet med den fremvoksende konkurransen fra bildeling?
(Master thesis; Mastergradsoppgave, 2024-06-03)I denne studien har jeg undersøkt hvordan Hertz kan tilpasse seg og opprettholde konkurransekraft i møtet med en fremvoksende konkurranse fra bildelingstjenester. Problemformuleringen undersøkes på bakgrunn av den interessante påvirkningen disruptive konsepter kan ha på den tradisjonelle bilutleiebransjen, hvor nyere bildelingsaktører som Getaround og Hyre introduserer innovative forretningsmodeller ... -
Har maskinlæringsteknikker bra prediksjonsevne på nordiske indekser?
(Master thesis; Mastergradsoppgave, 2024-06-01)Denne masteroppgaven undersøker hvorvidt maskinlæring kan utkonkurrere kjøp-og-hold-strategier i de nordiske aksjemarkedene. Arbeidet omfatter en komparativ studie av forskjellige maskinlæringsteknikker brukt til å forutsi aksjemarkedsbevegelser. Problemstillingen er: "Har maskinlæringsteknikker en god prediksjonsevne på nordiske aksjeindekser med lengre intervaller?" Random forest, kunstige nevrale ... -
Potensielle fusjoner av nettselskaper i Nord-Norge
(Master thesis; Mastergradsoppgave, 2024-06-03)Denne studien analyserer potensielle fusjoner mellom nettselskaper i Nord-Norge, for å undersøke hvordan fusjonene påvirker konkurransedyktigheten til de gitte selskapene i NVEs reguleringsmodell. For å danne fusjonspartnere blir forholdstall mellom input- og outputvariablene brukt, med mål om å finne partnere som i stor grad er ulike. Datagrunnlaget for analysen er hentet fra beregningen av ... -
Snøkrabbe på norsk sokkel i Barentshavet - Status og rådgivning for 2025
(Research report; Forskningsrapport, 2024-10-24)Basert på en MSY-tilnærming anbefaler Havforskningsinstituttet at totalfangsten av snøkrabbe på norsk sokkel i 2025 ikke bør overstige 12 724 tonn. Kvoterådet gjelder for den høstbare delen av bestanden, som er snøkrabbe over minstemålet på 95 mm skallbredde. -
Unlocking the potential of sedimentary ancient DNA
(Doctoral thesis; Doktorgradsavhandling, 2024-11-15)Past ecosystem dynamics provide valuable information to inform current and future management. Ancient DNA has rapidly become a powerful tool in uncovering these lost environments. We demonstrate the ecological inferences made possible by metabarcoding analysis on sedimentary ancient DNA by investigating the role climate and glacial activity have had on a catchment’s vegetation community. We identified ... -
Capture and Release of Minke Whales Offers New Research Opportunities, Including Measurements of Mysticete Hearing
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024)Knowledge about species-specific hearing is vital to assessing how anthropogenic noise impacts marine mammals. Unfortunately, no empirical audiogram exists for any mysticete whale. We therefore developed a catch-and-release method to assess hearing in a small mysticete, the minke whale (Balaenoptera acutorostrata). Stationary lead nets were placed to intercept migratory routes and direct the whales ... -

Joint Russian Norwegian Arctic Fisheries Working Group (JRN-AFWG) Report 2024
(Research report; Forskningsrapport, 2024-06-21)On 30th March 2022 all Russian participation in ICES was temporally suspended. Although the announcement of the suspension stressed the role of ICES as a “multilateral science organization”, this suspension applied not only to research activities, but also to the ICES work providing fisheries advice for the sustainable management of fish stocks and ecosystems. As a result of the suspension, the ICES ... -
