Interaction Effects of Ocean Acidification and Warming on the Marine Copepod Calanus finmarchicus
(Master thesis, 2014)Ocean acidification and concurring warming of the oceans poses an ongoing threat to marine organisms, but little is known about their combined effects. The boreal calanoid copepod Calanus finmarchicus is a key stone species ... -
Interaction of neural stem cells and glial cells with 2D and 3D Matrices
(Master thesis, 2013)Repair of spinal cord or brain injury is a challenge in today?s world as well as the center of attention of neuroscientists. Cell transplantation and in situ tissue engineering are promising approaches for central nervous ... -
Interaction of soyasaponins with plant ingredients in diets for Atlantic salmon, Salmo salar L
(Journal article; Peer reviewed, 2012)The effects of combining soyasaponins with plant ingredients on intestinal function and fish health were investigated in an 80 d study with Atlantic salmon (270 g) distributed thirty each into twenty-four tanks with seawater. ... -
Interactions between demography and environmental effects are important determinants of population dynamics
(Journal article; Peer reviewed, 2017)Climate change will affect the population dynamics of many species, yet the consequences for the long-term persistence of populations are poorly understood. A major reason for this is that density-dependent feedback effects ... -

Interactions between local population density and limited habitat resources determine movements of juvenile Atlantic salmon
(Journal article; Peer reviewed, 2017)Competition for limited resources and the resulting density-dependent processes are key factors in driving stream salmonid population dynamics. Here we test for the combined effects of density and shelter availability on ... -
Interactions between marine osmo- and phagotrophs in different physicochemical environments
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:124, Doctoral thesis, 2005)The interaction between the marine phototrophic dinoflagellate Prorocentrum minimum and associated bacteria was studied in different physico-chemical environments in batch cultures. In stagnant cultures the dinoflagellates ... -
Interactions between Pollutant Exposure and the Physiology in Adult Kittiwakes (Rissa tridactyla) at Svalbard
(Master thesis, 2015)This study investigated the use of feathers as a useful non-destructive biomonitoring tool for novel organic pollutants in black-legged kittiwakes (Rissa tridactyla), and evaluated the interaction of both novel and legacy ... -
Interactions Between Sea trout and Farmed Salmonids: Risk of pathogen exchange with special emphasis on Piscine orthoreovirus (PRV)
(Master thesis, 2019)Forståelse av patogenutveksling mellom oppdrettet og ville laksefisker er viktig for å stadfeste økologiske påvirkninger fra akvakultur på ville populasjoner. En risikovurdering av patogenutveksling ble derfor utført ved ... -
Interactions between woody plants, elephants and other browsers in the Chobe Riverfront, Botswana
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:214, Doctoral thesis, 2005)This thesis examines the interaction between woody plants, elephants and other browsers in a semi-arid savanna in northern Botswana, southern Africa. Particularly I studied how woody plants respond to herbivory, how browsers ... -
Interactive Effects of Inorganic Mercury and Temperature on Production of Resting Eggs and Population Dynamics in Daphnia magna
(Master thesis, 2018)Freshwater ecosystems are particularly vulnerable to the effects of climate change. In addition to the predicted increase in global surface temperatures, expected change in patterns of precipitation and wind can significantly ... -
Interaksjoner mellom osmoregulering og syre/base-regulering hos Calanus finmarchicus (Gunnerus)
(Master thesis, 2012)Calanus finmarchicus er en nøkkelart i transporten av energi mellom primærprodusentene og høyere trofiske nivåer i Nord-Atlanteren. Økende atmosfærisk CO2 vil føre til forsuring av verdenshavene. Det er begrenset kunnskap ... -
Interhemispheric connections between olfactory bulbs improve odor detection
(Peer reviewed; Journal article, 2020)Interhemispheric connections enable interaction and integration of sensory information in bilaterian nervous systems and are thought to optimize sensory computations. However, the cellular and spatial organization of ... -
Intersexual conflict over seed size is stronger in more outcrossed populations of a mixed-mating plant
(Journal article; Peer reviewed, 2018)In polyandrous species, fathers benefit from attracting greater maternal investment toward their offspring at the expense of the offspring of other males, while mothers should usually allocate resources equally among ... -
Interspecific analysis of vehicle avoidance behaviour in birds
(Journal article, 2014)Among the most widespread forms of anthropogenic modification of the natural landscape is road construction, with vehicle mortality a major issue affecting amphibians, reptiles, mammals, and birds. Why some species are ... -
Intestinal Cetobacterium and acetate modify glucose homeostasis via parasympathetic activation in zebrafish
(Peer reviewed; Journal article, 2021)The capability of carbohydrate utilization in fish is limited compared to mammals. It has scientific and practical significance to improve the ability of fish to use carbohydrates. The efficiency of dietary carbohydrate ... -
Intestinal health in Atlantic salmon post-smolt (Salmo salar) when fed low- and high HUFA diets
(Peer reviewed; Journal article, 2022)It is well established that farmed Atlantic salmon (Salmo salar) need n3-highly unsaturated fatty acids (HUFA) in their diet to thrive and grow. However, the biological functions to the individual HUFAs may differ, implying ... -
Intestinal uptake of polystyrene (PS) and polyethylene terephthalate (PET) nanoplastic particles in the Atlantic salmon (Salmo salar) parr and post-smolt, and translocation of PET nanoplastic particles to the circulatory system and liver in parr.
(Master thesis, 2019)Mikro- (20 µm – 5 mm) og nano- (< 20 µm) plast utgjør i dag en stor miljøbekymring gjennom akkumulering i marine miljø. Nyere studier viser også at marine vertebrater og invertebrater inntar plastpartikler og at disse ... -
