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 responses of Northern Elephant Seals (Mirounga angustirostris) endothelial cells to contaminants under hypoxic and high pressure conditions
(Master thesis, 2024-11-27)Northern elephant seals (Mirounga angustirostris), as apex predators in their marine ecosystem, are vital for maintaining ecological balance. These seals are expert divers, frequently reaching depths below 600 meters, where ... -
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 ... -
Indigenous Ammonia-Oxidizing Archaea in Oxic Subseafloor Oceanic Crust
(Journal article, 2020-03-10)Oceanic ridge flank systems represent one of the largest and leastexplored microbial habitats on Earth. Fundamental ecological questions regarding community activity, recruitment, and succession in this environment remain ... -
Indiscriminately Loving Sticklebacks. A test of assortative mate preferences between two morphologically diverged parapatric populations of threespine stickleback (Gasterosteus aculeatus L.) concerning pelvic reduction
(Master thesis, 2013-06-07)Two parapatric populations in western Norway in which one have completely reduced its pelvic complex are tested for assortative mating being an important mechanism in maintaining barriers keeping them from mixing in their ... -
Individual habitat transitions of Atlantic herring Clupea harengus in a human-modified coastal system
(Peer reviewed; Journal article, 2015-02-03)Pelagic marine fish often display highly dynamic migration patterns. However, such movement behaviour is usually studied at the population or school level, while less is known about individual movement characteristics and ... -
Individual variation in competitive performance in juvenile cod

Individual-based model highlights the importance of trade-offs for virus-host population dynamics and long-term coexistence
(Journal article; Peer reviewed, 2022)Viruses play diverse and important roles in ecosystems. In recent years, trade-offs between host and virus traits have gained increasing attention in viral ecology and evolution. However, microbial organism traits, and ... -
Induction of tenacibaculosis in Atlantic salmon smolts using Tenacibaculum finnmarkense and the evaluation of a whole cell inactivated vaccine
(Peer reviewed; Journal article, 2018-10)Tenacibaculosis, an ulcerative disease characterised by skin lesions, mouth erosion, frayed fins and tail rot, is a significant fish welfare issue in marine aquaculture worldwide. The disease is a concern to the Atlantic ... -
