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 ... -
Interaksjoner mellom marine næringsstoffer og dioksiner hos mus med human AhR
(Master thesis, 2021-11-22)Dioksiner og dioksinlignende PCB er en gruppe kjemiske forbindelser dannet via industrielle prosesser, som grunnet høy persistens vil akkumulere i fettvev hos mennesker og dyr. Fet fisk regnes som den største kilden til ... -
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, ... -
Intergeneric relationships within the subfamily Rosoideae (Rosaceae) with emphasis on Rubus L.
(Master thesis, 2018-06-29)The genus Rubus belongs to the Rose family, and is currently placed in the supertribe Rosodae, of the subfamily Rosoideae. Further systematic placement of Rubus has not yet been clarified, although several hypotheses have ... -
Interleukin-1 ligands and receptors in lumpfish (Cyclopterus lumpus L.): molecular characterization, phylogeny, gene expression and transcriptome analyses
(Journal article; Peer reviewed, 2020-04-02)The interleukin (IL)-1 family play a fundamental role as immune system modulators. Our previous transcriptome-analyses of leukocytes from lumpfish (Cyclopterus lumpus L.) showed that IL-1β was among the most highly upregulated ... -
Interpreting the polychromatic variation of the European nudibranch Polycera quadrilineata (O. F. Müller, 1776), with the description of a new species
(Master thesis, 2019-11)The polychromatic variability exhibited by the dorid nudibranch species Polycera quadrilineata (O. F. Müller, 1776) (Family Polyceridae) has long fascinated marine scientists. The species was originally described from the ... -
Interspecific differences in root foraging precision cannot be directly inferred from species' mycorrhizal status or fine root economics
(Journal article; Peer reviewed, 2023)Nutrient acquisition in plants can be represented by a suite of intercorrelated root traits such as root diameter, nitrogen content, root tissue density and specific root length. However, it is unclear how a plant's ability ... -
