Comparing the size selectivity of a novel T90 mesh codend to two conventional codends in the northern shrimp (Pandalus borealis) trawl fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-28)The size selectivity and usability of three codends were quantified and compared for the first time in the inshore Northern shrimp (<i>Pandalus borealis</i>) trawl fishery of Iceland using the covered codend method: a conventional diamond-mesh codend (T0), conventional square-mesh codend (T45), and a 90° turned mesh codend (T90) constructed of four panels and with shortened lastridge ropes. Fishers, ... -
The Atlantic Salmon Gill Transcriptome Response in a Natural Outbreak of Salmon Gill Pox Virus Infection Reveals New Biomarkers of Gill Pathology and Suppression of Mucosal Defense
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-04)The salmon gill poxvirus (SGPV) is a large DNA virus that infects gill epithelial cells in Atlantic salmon and is associated with acute high mortality disease outbreaks in aquaculture. The pathological effects of SGPV infection include gill epithelial apoptosis in the acute phase of the disease and hyperplasia of gill epithelial cells in surviving fish, causing damage to the gill respiratory surface. ... -
Weakening of Cold Halocline Layer Exposes Sea Ice to Oceanic Heat in the Eastern Arctic Ocean
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-20)A 15-yr duration record of mooring observations from the eastern (>70°E) Eurasian Basin (EB) of the Arctic Ocean is used to show and quantify the recently increased oceanic heat flux from intermediate-depth (~150–900 m) warm Atlantic Water (AW) to the surface mixed layer and sea ice. The upward release of AW heat is regulated by the stability of the overlying halocline, which we show has weakened ... -

Marine biomonitoring with eDNA: Can metabarcoding of water samples cut it as a tool for surveying benthic communities?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-24)In the marine realm, biomonitoring using environmental DNA (eDNA) of benthic communities requires destructive direct sampling or the setting‐up of settlement structures. Comparatively much less effort is required to sample the water column, which can be accessed remotely. In this study we assess the feasibility of obtaining information from the eukaryotic benthic communities by sampling the adjacent ... -
Ocular Histopathological Findings in Semi-Domesticated Eurasian Tundra Reindeer (Rangifer tarandus tarandus) with Infectious Keratoconjunctivitis after Experimental Inoculation with Cervid Herpesvirus 2
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-09)Infectious keratoconjunctivitis (IKC) is a common transmissible ocular disease in semi-domesticated Eurasian tundra reindeer (<i>Rangifer tarandus tarandus</i>). In large outbreaks, IKC may affect tens of animals in a herd, with the most severe cases often requiring euthanasia due to the destruction of the affected eyes and permanent blindness. An experimental inoculation with cervid herpesvirus 2 ... -
Microbial eukaryotes and their functional importance in the Arctic. A Svalbardian perspective
(Doctoral thesis; Doktorgradsavhandling, 2020-11-06)<p>Microbial eukaryotes, including protists and fungi, play diverse functions in virtually all ecosystems. In the High Arctic, their high biomass and diversity reflects crucial ecological importance and the performance of key ecological processes. Protists are the main primary producers in arctic seas, whereas fungi are an important group of decomposers and symbiotic partners of plants in terrestrial ... -
Foraging behaviour of humpback whales (Megaptera novaeangliae): Automatic detection of feeding lunges from two-dimensional data
(Master thesis; Mastergradsoppgave, 2020-09-10)Rorqual whales (Family Balaenopteridae) forage almost exclusively by performing so-called feeding lunges. It is difficult to study rorqual foraging behaviour through direct observation because most of the lunges are carried out deep in the water column. The introduction of high-resolution digital tags recording three-dimensional (3D) acceleration has allowed for the collection of complex movement ... -
Individual differences in functional food consumption: The role of time perspective and the Big Five personality traits
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-24)Prior research suggests inconsistent relationships between individuals’ personality traits, time perspective, and specific behavior. In a large representative sample of Norwegian consumers (<i>N</i> = 810), we investigated the relationships between the Big Five personality traits, domain-specific consideration of future consequences (CFC), and consumption of functional foods. Structural equation ... -
Life history genomic regions explain differences in Atlantic salmon marine diet specialization
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-16)1. Animals employ various foraging strategies along their ontogeny to acquire energy, and with varying degree of efficiencies, to support growth, maturation and subsequent reproduction events. Individuals that can efficiently acquire energy early are more likely to mature at an earlier age, as a result of faster energy gain which can fuel maturation and reproduction.<p><p> 2. We aimed to test the ... -
Pan-Arctic analysis of cultural ecosystem services using social media and automated content analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-02)In the Arctic, as in many parts of the world, interactions with the natural world are an important part of people's experience and are often recorded in photographs. Emerging methods for automated content analysis of social media data offers opportunities to discover information on cultural ecosystem services from photographs across large samples of people and countries. We analysed over 800 000 ... -
Space-time dynamics in monitoring neotropical fish communities using eDNA metabarcoding
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-01)The biodiverse Neotropical ecoregion remains insufficiently assessed, poorly managed, and threatened by unregulated human activities. Novel, rapid and cost-effective DNA-based approaches are valuable to improve understanding of the biological communities and for biomonitoring in remote areas. Here, we evaluate the potential of environmental DNA (eDNA) metabarcoding for assessing the structure and ... -

The Sunk Cost Fallacy and Risk-Taking Behaviour. Evidence from a computer game experiment
(Master thesis; Mastergradsoppgave, 2020-05-31)We examine whether behavioural sunk costs are related to an increased willingness to make risky decisions. Rational agents’ decisions should not be contingent on sunk costs; however, foregoing research suggests that individuals in fact do react to such costs. Few studies have examined behavioural sunk costs and risk-taking with “real stakes”, which is an important topic of research as many ... -
Strategisk kompetanseledelse i Nord-Norge. En kvalitativ studie av to småbedrifter
(Master thesis; Mastergradsoppgave, 2020-05-29)Sammendrag De menneskelige ressursene blir sett på som viktige i bedriftene, og i mange tilfeller vil de også være de ressursene som er avgjørende for lønnsomhet og vekst. Små bedrifter skiller seg ikke fra store i den sammenheng, men små bedrifter kan ha både muligheter og utfordringer som kan gjøre seg gjeldende i større grad enn de vil gjøre i store organisasjoner. I småbedrifter er gjerne leder ... -
Vil man effektivisere videoannonser i holdningskampanjer om de skreddersys mot mottakerens personlighet?
(Master thesis; Mastergradsoppgave, 2020-05-28)Regulatory focus theory er en teori som omhandler hvordan vi mennesker motiveres ulikt som følge av at noen av oss er avvergingsfokuserte og andre er avansefokuserte. Avvergingsfokuserte mennesker motiveres til handle slik de må for å unngå en uønsket endesituasjon. Avansefokuserte mennesker er motivert til å handle for å nå en ønsket endesituasjon. Tidligere har det blitt observert at om man ... -

Especially does the illness affect individuals with weaker immune systems. Treating sepsis presents some challenges as it requires rapidly detection and correct treatment. Virtual Reality (VR), which is defined as three-dimensional computer science, presents potential ... -
Use and non-use values in an applied bioeconomic model of fisheries and habitat connections
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-25)In addition to indirect support to fisheries, marine habitats also provide non-use benefits often overlooked in most bioeconomic models. We expand a dynamic bioeconomic fisheries model where presence of natural habitats reduces fishing cost via aggregation effects and provides non-use benefits. The theoretical model is illustrated with an application to cold-water corals in Norway where two fishing ... -
The Impact of Methane on Microbial Communities at Marine Arctic Gas Hydrate Bearing Sediment
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-24)Cold seeps are characterized by high biomass, which is supported by the microbial oxidation of the available methane by capable microorganisms. The carbon is subsequently transferred to higher trophic levels. South of Svalbard, five geological mounds shaped by the formation of methane gas hydrates, have been recently located. Methane gas seeping activity has been observed on four of them, ...
