Measured sound levels in ice-covered shallow water caused by seismic shooting on top of and below floating ice, reviewed for possible impacts on true seals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-01)Seismic surveying of the Arctic is important for several reasons, but also introduces some challenges. One is the concern that seismic data may affect the hearing of marine mammals living there, including true seals. We performed two seismic experiments on floating ice on Svalbard in the Norwegian Arctic in early March 2016 and late May 2017, just before and right after the ringed seal breeding ... -

Mechanistic model identifies increasing light availability due to sea ice reductions as cause for increasing macroalgae cover in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-04)In the Arctic, rising seawater temperatures and increasing underwater light caused by reductions in sea ice cover are expected to change the structure of arctic marine communities. Substantial, sometimes sudden, increases in macroalgal productivity and biomass have already been observed in arctic rocky bottom communities. These macroalgal responses have been attributed to increasing temperature and ... -
Med lov og skjønn skal kysten forvaltes
(Research report; Forskningsrapport, 2014)Gjennomgangen av lov- og regelverket viser at det skal ivareta mange hensyn. Lov- og regelverket er komplekst og følgelig vil også beslutningsprosessene være preget av denne kompleksiteten. De ulike lovene og forskriftene, og de bestemmelsene i hver enkelt lov og forskrift søker å ivareta både politiske, administrative og faglige hensyn. De forvaltes også på ulike politiske og administrative ... -

(Master thesis; Mastergradsoppgave, 2020-05-14)I denne oppgaven ble genuttrykket av MDA5, TLR3, TLR7, IFNa, IFNc, Mx, viperin, ISG15, STAT-1 og PKR studert hos atlantisk laks ved 488 døgngrader (rett etter klekking) og ca 848 døgngrader (omkring startfôring). Det ble undersøkt hvilke gener som utryktes mer eller mindre i forhold til hverandre, tidlig utvikling av genuttrykk (ontogeni) og effekt av lys- og temperatur på ekspresjon. Resultatene ... -
Mel av grisetang og mikroalger til bruk i fiskefôr? Kjemisk sammensetning og in vitro fordøyelse av protein.
(Master thesis; Mastergradsoppgave, 2022-05-12)Etterspørselen etter fisk og skalldyr globalt er stadig økende. Økt kjøpekraft og anbefalinger om å spise mer sjømat har bidratt betydelig til dette. De fleste villfiskbestander er allerede maksimalt utnyttet og økningen i produksjonen har i de siste 30 årene derfor utelukkende kommet fra oppdrett. I dag produseres mer fisk til humant konsum i oppdrett enn hva som høstes av villfisk. En av de største ... -

The melting snowball effect: A heuristic for sustainable Arctic governance under climate change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-08)Climate change in the Arctic is occurring at a rapid rate. In Longyearbyen, Svalbard, the world’s northernmost city, deadly avalanches and permafrost thaw-induced architectural destruction has disrupted local governance norms and responsibilities. In the North Atlantic, the warming ocean temperatures have contributed to a rapid expansion of the mackerel stock which has spurred both geo-political ... -
Mestringstro og ledelse. Hestehåndtering og mestring av lederskapsrollen hos kvinnelige ledere.
(Master thesis; Mastergradsoppgave, 2007-09-28)Tema for denne oppgaven var sammenhengen mellom opplevelsen av mestringsevne og lederatferd hos kvinnelige ledere. Videre gikk studien inn på hvilke lederegenskaper kvinnelige ledere opplevde at de fikk utviklet gjennom hestehåndtering og ridning. Bakgrunnen for at kvinnelige ledere ble valgt, er mangelen på kvinnelige ledere i Norge. Det er interessant å se på hvilke egenskaper kvinnelige ledere ... -
Metabarcoding of shrimp stomach content: harnessing a natural sampler for fish biodiversity monitoring
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-28)Given their positioning and biological productivity, estuaries have long represented key providers of ecosystem services, and consequently remain under remarkable pressure from numerous forms of anthropogenic impact. The monitoring of fish communities in space and time are one of the most widespread and established approaches to assess the ecological status of estuaries and other coastal habitats, ... -
Metabarcoding reveals high-resolution biogeographical and metaphylogeographical patterns through marine barriers
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-29)Aim: It has been predicted that there should be concordance between biogeographical and phylogeographical processes structuring multi-species regional assemblages. We hypothesise that oceanographic barriers in the marine environment affect concomitantly the distribution and the connectivity of the marine biota, thus producing congruent biogeographical and phylogeographical structures. We also ... -
Metazoan Parasites in deep-sea sharks Part I. A Review of the Parasite Fauna of sharks of the genus Etmopterus Part II. Metazoan gastrointestinal parasites of Etmopterus spinax (L., 1758) from southern Norwegian waters
(Master thesis; Mastergradsoppgave, 2019-11-15)Parasites play an important role in ecology due to their potential influence on the biodiversity and dynamics of ecosystems. The complexity of interaction between parasites and their hosts is crucial to understanding the host’s populations dynamics, behaviour as well as interconnections between food chains in an ecosystem. Parasites have wide applications as bio-indicators for example to detect and ... -

Microbial danger signals control transcriptional induction of distinct MHC class I L lineage genes in Atlantic salmon
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-11)Antigen processing and presentation by major histocompatibility complex (MHC) molecules is a cornerstone in vertebrate immunity. Like mammals, teleosts possess both classical MHC class I and multiple families of divergent MHC class I genes. However, while certain mammalian MHC class I-like molecules have proven to be integral in immune regulation against a broad array of pathogens, the biological ... -
Microbial trimethylamine-N-oxide as a disease marker: something fishy?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-19)Production of trimethylamine-N-oxide (TMAO) via the gut microbiota has recently been proposed as an important pathophysiological mechanism linking ingestion of ‘unhealthy foods’, such as beef (containing carnitine) and eggs (containing choline), and the development of atherosclerosis. Hence, TMAO has gained attention as a novel biomarker for cardiovascular disease. However, fish and seafood contain ... -
Microplastics in fish and shellfish - A threat to seafood safety?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-23)Plastic litter in the oceans is a major environmental problem, and small size plastics (microplastics) have been detected in many species of fish and shellfish consumed by humans. The purpose of this paper is to evaluate the knowledge on microplastics in fish and shellfish in relation to a possible threat to seafood safety. In fish and crustacean species, the presence of microplastics has in most ...
