Insect frass as a fertilizer for the cultivation of protein-rich Chlorella vulgaris
(Journal article; Peer reviewed, 2024)Replacing the large amounts of chemical fertilizer with nutrients from waste or residual streams is an important factor to make microalgal production more sustainable, cost-effective, and part of a circular bioeconomy. ... -
Insect glycerol transporters evolved by functional co-option and gene replacement
(Peer reviewed; Journal article, 2015-07-17)Transmembrane glycerol transport is typically facilitated by aquaglyceroporins in Prokaryota and Eukaryota. In holometabolan insects however, aquaglyceroporins are absent, yet several species possess polyol permeable ... -
Insects reared on seaweed as novel feed ingredients for Atlantic salmon (Salmo salar) : Investigating the transfer of essential nutrients and undesirable substances along the seaweed-insect-fish food chain
(Doctoral thesis, 2020-12-09)Traditionally, major sources of protein and lipid in aquaculture fish feeds have been fish meal and fish oil. However, fish stocks used for fish meal and fish oil production are fully exploited, therefore prices of these ... -
Insights into NAD homeostasis in the compartmentalized cell
(Doctoral thesis, 2015-08-24)The compartmentalized nature of eukaryotic cells requires the distribution of enzymes, metabolites, and cofactors among the organelles. This includes nicotinamide adenine dinucleotide (NAD), an essential coenzyme, precursor, ... -
Insights into the genetic diversity, antibiotic resistance and pathogenic potential of Klebsiella pneumoniae from the Norwegian marine environment using whole-genome analysis
(Journal article; Peer reviewed, 2022)Klebsiella pneumoniae (Kp) can cause hospital- and community acquired infections. Although, Kp is widespread in the environment, very little is known about the genetic diversity and pathogenicity of Kp from the marine ... -
Inspection of a novel object by wild and laboratory Zebrafish (Danio rerio H.) in the presence and absence of alarm substance
(Master thesis, 2008)Zebrafish (Danio rerio) is a small Ostariophysian cyprinid fish with no special body armour, which makes them vulnerable to predation. They possess chemical alarm pheromones (Schreckstoff) in the epidermal club cells, ... -
Instar growth and Development of Lepeophtheirus salmonis Copepodids.
(Master thesis, 2009-05-07)Salmon louse Lepeophtheirus salmonis, (Krøyer, 1837) is a caligid parasite, responsible for major economical loss and welfare issues in Norwegian marine culture of salmonid species. Infections are mainly controlled with ... -
Instar growth and molt increments in Lepeophtheirus salmonis (Copepoda: Caligidae) chalimus larvae
(Peer reviewed; Journal article, 2015-02)The salmon louse (Lepeophtheirus salmonis) is an ectoparasitic copepod causing severe problems to the fish farming industry and to wild salmonids. Morphologically, all stages in the life cycle of L. salmonis have been ... -
Integrating human dimensions in decadal-scale prediction for marine social–ecological systems: lighting the grey zone
(Journal article; Peer reviewed, 2023)The dynamics of marine systems at decadal scales are notoriously hard to predict—hence references to this timescale as the “grey zone” for ocean prediction. Nevertheless, decadal-scale prediction is a rapidly developing ... -
Integration matters: Combining socio-cultural and biophysical methods for mapping ecosystem service bundles
(Journal article; Peer reviewed, 2023)Ecosystem services (ESs) play an important role in sustainable landscape management. People value ESs in diverse ways encompassing social and ecological domains and we need to bring these different values together. We used ... -
Integrative omics-analysis of lipid metabolism regulation by peroxisome proliferator-activated receptor a and b agonists in male Atlantic cod
(Journal article; Peer reviewed, 2023-03-22)Lipid metabolism is essential in maintaining energy homeostasis in multicellular organisms. In vertebrates, the peroxisome proliferator-activated receptors (PPARs, NR1C) regulate the expression of many genes involved in ... -
Intensive Farming: Evolutionary Implications for Parasites and Pathogens
(Peer reviewed; Journal article, 2010)An increasing number of scientists have recently raised concerns about the threat posed by human intervention on the evolution of parasites and disease agents. New parasites (including pathogens) keep emerging and parasites ... -
Inter-laboratory testing of the effect of DNA blocking reagent G2 on DNA extraction from low-biomass clay samples
(Peer reviewed; Journal article, 2018-04-09)Here we show that a commercial blocking reagent (G2) based on modified eukaryotic DNA significantly improved DNA extraction efficiency. We subjected G2 to an inter-laboratory testing, where DNA was extracted from the same ... -
Inter-specific aggression generates ant mosaics in canopies of primary tropical rainforest
(Journal article; Peer reviewed, 2021)The ant mosaic is a concept of the non-random spatial distribution of individual ant species in trees built upon the assumption of interspecific behavioural associations. However, colony identity and environmental variance ... -
Inter-viral conflicts that exploit host CRISPR immune systems of Sulfolobus
(Peer reviewed; Journal article, 2014-03)Infection of Sulfolobus islandicus REY15A with mixtures of different Sulfolobus viruses, including STSV2, did not induce spacer acquisition by the host CRISPR immune system. However, coinfection with the tailed fusiform ... -
The interaction between water currents and salmon swimming behaviour in sea cages
(Peer reviewed; Journal article, 2014-05-15)Positioning of sea cages at sites with high water current velocities expose the fish to a largely unknown environmental challenge. In this study we observed the swimming behaviour of Atlantic salmon (Salmo salar L.) at a ... -
Interaction of temperature and feed ration on male postsmolt maturation of Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2023)Early maturation of Atlantic salmon male postsmolts is undesirable in aquaculture due to its negative impact on growth, welfare and seawater adaptation, however it is an increasing problem under intensive rearing conditions. ... -
Interaction of temperature and photoperiod on male postsmolt maturation of Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2023)Maturation of Atlantic salmon male postsmolts is a concern in aquaculture due to its increasing occurrence under intensive rearing conditions and its negative impact on growth, welfare and seawater readiness. The effect ... -
Interaction patterns and specialization in a local and national Norwegian pollination network
(Master thesis, 2014-06-02)Pollination is an important ecosystem service that is threatened and not very well studied in Norway. Interaction patterns and specialization is one important aspect of pollination that needs to be studied to better ... -
Interactions between Eurasian otters (Lutra lutra) and American mink (Neovison vison) in western Norway: A camera trap study over space and time
(Master thesis, 2019-08-28)Classic ecological theory suggests that a large amount of niche overlap between two competing species will lead to the decline or exclusion of the less dominant species. However, despite competition being a major evolutionary ...
