The important role of sponges in carbon and nitrogen cycling in a deep-sea biological hotspot
(Journal article; Peer reviewed, 2022)Deep-sea sponge grounds are hotspots of biodiversity, harbouring thriving ecosystems in the otherwise barren deep sea. It remains unknown how these sponge grounds survive in this food-limited environment. Here, we unravel ... -
Improbable but true: the invasive inbreeding ambrosia beetle Xylosandrus morigerus has generalist genotypes
(Peer reviewed; Journal article, 2012-01)The wide distribution and dominance of invasive inbreeding species in many forest ecosystems seems paradoxical in face of their limited genetic variation. Successful establishment of invasive species in new areas is ... -
Improved density measurements of mesopelagic fish and the presence of physonect siphonophores in sound scattering layers, measured with multifrequency acoustics and a stereo camera mounted on a lowered probe
(Master thesis, 2018-12-11)The mesopelagic layer is a massive layer of biomass which stretches from 200-1000 meters depth in almost all locations of the world oceans. These layers are inhabited by many groups of animals, from small zooplankton to ... -
Improving Salmonid Monitoring by Nocturnal Counting in Rivers
(Journal article; Peer reviewed, 2022)Accurate abundance estimates are crucial for evidence-based fisheries management. In rivers, drift dive counting and electrofishing are commonly used for quantifying fish abundance. However, the likelihood that fish are ... -
Improving size selection in the Norwegian red king crab (Paralithodes camtschaticus) fishery through modification to pot design and soak time
(Journal article; Peer reviewed, 2023)Red king crab (Paralithodes camtschaticus) represent a valuable inshore fisheries resource for communities in northern Norway. The fishery is regulated east of the 26th meridian by vessel quotas and a minimum landing size ... -
In lumpfish We Trust? The Efficacy of Lumpfish Cyclopterus lumpus to Control Lepeophtheirus salmonis Infestations on Farmed Atlantic Salmon: A Review
(Journal article; Peer reviewed, 2022)In this review, we have systematized current knowledge about the effect of stocking lumpfish (Cyclopterus lumpus) as cleaner fish to control Lepeophtheirus salmonis infestations on farmed Atlantic salmon (Salmo salar L.). ... -
In situ hybridisering for deteksjon av cytokrom P450 1A i presisjonskuttede leverskiver (PCLS) fra atlanterhavstorsk (Gadus morhua)
(Master thesis, 2016-06-01)Marine arter og økosystemer blir utsatt for menneskeskapte stoffer fra en rekke ulike kilder. Siden de biologiske effektene for mange av disse stoffene ikke er godt karakterisert er det derfor behov for gode og effektive ... -
In the dark: a review of ecosystem processes during the Arctic polar night
(Peer reviewed; Journal article, 2015-08-28)Several recent lines of evidence indicate that the polar night is key to understanding Arctic marine ecosystems. First, the polar night is not a period void of biological activity even though primary production is close ... -
In vitro assessment of protein digestibility and mineral solubility of black soldier fly larvae meals for monogastric animals
(Journal article; Peer reviewed, 2022)Animal farming is a fast-growing sector which demands a large supply of feed materials and the search for novel feed ingredients with a smaller impact on the global environment has been intensified. However, before the ... -
In vitro bacterial and viral response in head kidney leukocytes of Atlantic salmon (Salmo salar) fed dietary insects meal.
(Master thesis, 2018-06-07)With the fast growth of today’s aquaculture industry, the demand for aqua-feeds is expanding dramatically. Insects, which are part of the natural diet of salmonids, could represent a sustainable ingredient for aquaculture ... -
In vitro digestion method to evaluate solubility of dietary zinc, selenium and manganese in salmonid diets
(Journal article; Peer reviewed, 2020)Background The determination of dietary mineral solubility is one of the main steps in the evaluation of their availability for a given species. Methods This study proposed an in vitro digestion method (acidic and ... -
In vitro responses of fin whale (Balaenoptera physalus) fibroblasts to plasticizers and their metabolites
(Master thesis, 2024)Phthalates, plasticizers that maintain plastic’s durability and flexibility, are chemicals that leach from plastics into the environment. As endocrine disruptors, they can bind to nuclear receptors regulating metabolism ... -
In-vitro characterization of pancreatic functional units from Cel-MODY mice
(Master thesis, 2021-06-01)The digestive enzyme carboxyl-ester lipase (CEL) is secreted by pancreatic acinar cells into the duodenum where it hydrolyzes dietary fat, cholesteryl esters, and fat-soluble vitamins. To date, two single-base mutations ... -
Increased Thermal Challenges Differentially Modulate Neural Plasticity and Stress Responses in Post-Smolt Atlantic Salmon (Salmo salar)
(Journal article; Peer reviewed, 2022)The successful transfer of farmed post-smolt Atlantic salmon (Salmo salar) depends on proper stress responses and cognitive functions during the early seawater (SW) phase. However, with increasing summer oceanic temperatures, ... -
Increasing plant species richness by seeding has marginal effects on ecosystem functioning in agricultural grasslands
(Journal article; Peer reviewed, 2023)Experimental evidence shows that grassland plant diversity enhances ecosystem functioning. Yet, the transfer of results from controlled biodiversity experiments to naturally assembled ‘real world’ ecosystems remains ... -
Increasing temperature and prey availability affect the growth and swimming kinematics of Atlantic herring (Clupea harengus) larvae
(Journal article; Peer reviewed, 2022)Climate change will increase the magnitude and duration of warming events and the variability in the phenology and abundance of available prey to the early life stages of fish. These factors influence physiological, ... -
Increasing the levels of the essential trace elements Se, Zn, Cu and Mn in rotifers (Brachionus plicatilis) used as live feed
(Peer reviewed; Journal article, 2013-03-04)Rotifers are a common first feeding diet for rearing marine fish larvae. However, the levels of Mn, Cu, Zn, Se and iodine found in rotifers are low and may be insufficient to meet larval fish requirements. This study ... -
Independent losses of a xenobiotic receptor across teleost evolution
(Peer reviewed; Journal article, 2018-07-10)Sensitivity to environmental stressors largely depend on the genetic complement of the organism. Recent sequencing and assembly of teleost fish genomes enable us to trace the evolution of defense genes in the largest and ... -
