Vertical distribution of epibenthic megafauna of a large seamount west of Cape Verde islands (tropical North Atlantic)
(Journal article; Peer reviewed, 2024)Seamounts are thought to function as hotspots of megafauna diversity due to their topology and environmental characteristics. However, assessments of megafauna communities inhabiting seamounts, including diversity and ... -
Biotic transformation of methylmercury at the onset of the Arctic spring bloom
(Journal article; Peer reviewed, 2024)Despite the lack of local anthropogenic mercury sources, methylated mercury (MeHg) concentrations in Arctic biota are higher than in biota from lower latitudes. The main entry route occurs during the bioconcentration of ... -
Effects of time spent in pregnancy or brooding on immunocompetence
(Journal article; Peer reviewed, 2024)Sexes of a species may show different characteristics beyond the differences in their sexual organs and such sexual dimorphism often occurs in the level of immune response when exposed to pathogens (immunocompetence). In ... -
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 ... -
