A comparative study of the alternative life history of iteroparous salmonids
(Journal article; Peer reviewed, 2024)The kelt phase of anadromous iteroparous salmonid life history remains mysterious, particularly aspects of their habitat use and factors influencing survival. Atlantic salmon and sea-run brown trout were captured in the ... -
An 18S V4 rDNA metabarcoding dataset of protist diversity in the Atlantic inflow to the Arctic Ocean, through the year and down to 1000 m depth
(Journal article, 2021)Arctic marine protist communities have been understudied due to challenging sampling conditions, in particular during winter and in deep waters. The aim of this study was to improve our knowledge on Arctic protist diversity ... -
Diversity, habitat endemicity and trophic ecology of the fauna of Loki’s Castle vent field on the Arctic Mid-Ocean Ridge
(Journal article; Peer reviewed, 2024)Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field discovered on the Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of the LCVF has not ... -
Interannual differences in sea ice regime in the north-western Barents Sea cause major changes in summer pelagic production and export mechanisms
(Journal article; Peer reviewed, 2024)The Barents Sea is a highly dynamic and productive marine ecosystem and a hotspot of global warming. Variability in sea ice extent is a common feature in the Barents Sea with substantial movements of the sea ice edge on ... -
Geodiversity and Biodiversity
(Journal article; Peer reviewed, 2023)Non-living and living nature are inherently connected. Geodiversity, which consists of the variation in geology, soils, topography, geomorphology and hydrology, is seen as the foundation and stage for biodiversity. Underlying ... -
Blue mussel (Mytilus edulis) silage, a possible low trophic marine protein source for Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2024)Blue mussel (Mytilus edulis) could be a promising marine protein source in fish feeds and is of great interest since it can be cultivated along the Norwegian coastline. However, the use of blue mussels in feeds is dependent ... -
Exploring the use of blue mussel silage and fermented sugar kelp as low trophic marine resources in the Atlantic salmon (Salmo salar L.) diet
(Doctoral thesis, 2024-09-25)Havbrukssektoren er i rask vekst og er forventa å bidra med meir mat frå havet til den globale matforsyninga. Berekraftig vekst i fiskeoppdrett er avhengig av å finne nye fôringrediensar som har potensiale for oppskalering ... -
Heterologous production, purification and substrate usage of a variant of the marine globupain protease
(Master thesis, 2024-02-01) -
Effects of different photoperiods regimes on growth and osmoregulation in Atlantic salmon
(Master thesis, 2024-03-20) -
Composition of Gelatinous Zooplankton Communities in Korsfjord and Fanafjord: seasonal dynamics and change over 20 years
(Master thesis, 2024-02-22)Marine zooplankton are vital components of pelagic ecosystems. Gelatinous zooplankton refers to a polyphyletic group of soft-bodied gelatinous organisms including the pelagic cnidarians and ctenophores. Despite being an ... -
Selenoprotein determination in tissues of Atlantic salmon (Salmo salar)
(Master thesis, 2024-06-03)Selen er et viktig mikronæringsstoff for både mennesker og dyr, inkludert fisk som Atlantisk laks (Salmo salar), og har en viktig rolle innen antioksidantforsvar og proteinsyntese. Hos fisk så er kostholdet hovedkilden for ... -
Annelid functional genomics reveal the origins of bilaterian life cycles
(Journal article; Peer reviewed, 2023)Indirect development with an intermediate larva exists in all major animal lineages1, which makes larvae central to most scenarios of animal evolution2,3,4,5,6,7,8,9,10,11. Yet how larvae evolved remains disputed. Here we ... -
Light and temperature controls of aquatic plant photosynthesis downstream of a hydropower plant and the effect of plant removal
(Journal article; Peer reviewed, 2023)Many rivers worldwide are regulated, and the altered hydrology can lead to mass development of aquatic plants. Plant invasions are often seen as a nuisance for human activities leading to costly remedial actions with ... -
Holocene changes in the position of the Southern Hemisphere Westerlies recorded by long-distance transport of pollen to the Kerguelen Islands
(Journal article; Peer reviewed, 2024)The Southern Hemisphere Westerlies (SHW) are a vital part of the Southern Hemisphere's coupled ocean-atmosphere system and play an important role in the global climate system. The SHW affect the upwelling of carbon-rich ... -
Winds of change : A multi-proxy approach to constrain Holocene climate and wind dynamics in the sub-Antarctic
(Doctoral thesis, 2024-09-05)Kunnskap om tidligere tiders naturlige klimavariasjoner er hovednøkkelen for å forstå vår nåværende klimatilstand. Det er også viktig for å kunne vurdere omfanget og retningen til fremtidige klimaendringer som forventes ... -
Metabolic pathways and physiological functions of organic and inorganic trace minerals in Atlantic Salmon
(Doctoral thesis, 2024-09-05)Mineralernæring spiller en nøkkelrolle for helse, velferd og prestasjonen til oppdrettet Atlantisk laks (Salmo salar), da den påvirker ulike fysiologiske prosesser, avgjørende for vekst, metabolisme og immunfunksjon. Blant ... -
Intermittent fasting in ongrowing Atlantic salmon (Salmo salar) reared in sea cages: Effects on feed intake, appetite control and growth
(Master thesis, 2023-11-20)Farmed Atlantic salmon are normally fed at a daily basis and fasted before operational procedures and harvest. While the biological mechanisms and effects of short and long-term fasting are largely known, there is sparse ... -
How formal initiatives to improve teaching can lead to more significant informal conversations and increased sharing practice
(Journal article; Peer reviewed, 2023)University teachers grow professionally from conversations about learning and teaching with colleagues. Significant informal conversations can be facilitated through formal activities initiated from the institutional side. ... -
Seasonality of the bacterial and archaeal community composition of the Northern Barents Sea
