Apomixis occurs frequently along the entire American Cordillera
(Journal article; Peer reviewed, 2024)Apomictic plants mostly occur at higher latitudes and higher elevations, where they tend to occupy deglaciated areas. By analysing samples of the alpine floras of different latitudinal zones of the Americas (Argentina, ... -
Bubbling trouble: Effects of supersaturated water on benthic macroinvertebrates
(Journal article; Peer reviewed, 2024)The saturation of total dissolved gases (TDG) in water remains around 100%. Certain circumstances can lead to TDG values exceeding 100%, resulting in TDG supersaturation (TDGS). TDGS above about 110% can be toxic to animals ... -
Reading tea leaves worldwide: Decoupled drivers of initial litter decomposition mass-loss rate and stabilization
(Journal article; Peer reviewed, 2024)The breakdown of plant material fuels soil functioning and biodiversity. Currently, process understanding of global decomposition patterns and the drivers of such patterns are hampered by the lack of coherent large-scale ... -
Negative association of sea lice from fish farms on recreational fishing catches of Atlantic salmon
(Journal article; Peer reviewed, 2024)The question of whether and to what extent sea-louse (Lepeophtheirus salmonis) infestations from salmon farms influence wild Atlantic salmon survival has been subject to sustained scientific debate and political controversy. ... -
Validity of winter sampling for estimation of salmonid abundance by electrofishing
(Journal article; Peer reviewed, 2024)Electrofishing removal sampling is a common method for abundance estimation of juvenile salmonids in streams and is usually performed during autumn. European guidelines specify that sampling should be conducted at water ... -
Environmental drivers of increased ecosystem respiration in a warming tundra
(Journal article; Peer reviewed, 2024)Arctic and alpine tundra ecosystems are large reservoirs of organic carbon1,2. Climate warming may stimulate ecosystem respiration and release carbon into the atmosphere3,4. The magnitude and persistency of this stimulation ... -
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 ... -

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 ... -
