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 ... -
Interaction between dietary lipids and zinc in Atlantic salmon (Salmo salar)
(Doctoral thesis, 2024-12-13)Sink (Zn) er et av de viktige sporstoffene for fisk. Imidlertid har den raske utviklingen av oppdrettsnæringen for atlantisk laks ført til en stor erstatning av marine ingredienser med plantebaserte ingredienser, noe som ... -
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 ... -
Interactions between marine n-3 fatty acids and methylmercury in Atlantic salmon (Salmo salar)
(Doctoral thesis, 2011-12-19)Methylmercury (MeHg) is an environmental contaminant widely distributed in the aquatic environment. MeHg toxicity is characterized by a broad range of molecular cellular effects, often, if not always, induced through the ... -
Interactions between marine nutrients and 2, 3, 7, 8 – Tetrachlorodibenzo-p-dioxin toxicity on reproduction of male wistar han rats
(Master thesis, 2020-12-23)Dioxins and dioxin-like polychlorinated biphenyls (dl-PCBs) are chemical congeners formed as by-products from incomplete thermic reactions, found in the environment because of improper disposal from industrial processes ... -
Interactions between xenoestrogens and ketoconazole on hepatic CYP1A and CYP3A, in juvenile Atlantic cod (Gadus morhua)
(Peer reviewed; Journal article, 2005-02-08)Background: Xenoestrogens and antifungal azoles probably share a common route of metabolism, through hepatic cytochrome P450 (CYP) enzymes. Chemical interactions with metabolic pathways may affect clearance of both xenobiotics ... -
Interactions of arginine and polyamines on growth and metabolism in Atlantic salmon
(Doctoral thesis, 2014-10-09)Arginine and methionine are indispensable amino acids (AA) for Atlantic salmon, meaning that salmon is unable to produce these AA endogenously and is fully dependent on dietary supply. In addition to be substrates for ... -
Interactive effects of light quality during day extension and temperature on bud set, bud burst and paftl2, pacol1-2 and pasoc1 expression in norway spruce (Picea abies (L.) karst.)
(Journal article; Peer reviewed, 2021)Light and temperature are crucial factors for the annual growth rhythm of tree seedlings of the boreal and temperate zone. Dormant, vegetative winter buds are formed under short days (SD) and altered light quality. In the ... -
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 ... -
Interannual Variabilities of Nutrients and Phytoplankton off the Changjiang Estuary in Response to Changing River Inputs
(Journal article; Peer reviewed, 2020)Coastal ecosystems are strongly influenced by terrestrial inputs of freshwater, sediments, and nutrients, particularly in a megariver estuary of the Changjiang River. A remarkable increase in nutrient loading from the ... -
The intercept is a poor estimate of a calibrated radiocarbon age
(Peer reviewed; Journal article, 2004)Intercept-based methods of generating a point estimate of a calibrated radiocarbon date are very popular, but exhibit undesirable behaviour. They are highly sensitive to the mean of the radiocarbon date and to adjustments ... -
Interdependence between Perceived Cooperative Learning, Sense of Belonging, and Generic Skills in Undergraduate STEM Education
(Journal article; Peer reviewed, 2023)The development of sense of belonging and generic skills may be considered important to succeed in higher education and in life and may be enhanced through student group work. For group work to succeed, Social Interdependence ... -
An interdisciplinary, student-active course on UN Sustainable Development Goal 14: Life below water
(Journal article; Peer reviewed, 2021)Educating student to respond to Sustainable Development Goals (SDGs) calls for teaching and learning where students are at the centre of their own learning. Sustainability questions are ‘wicked problems’, where no single, ... -
