Identification and population genetic analysis of jellyfish blooms in Trondheimsfjord Role of polyps in jellyfish populations connectivity
(Master thesis, 2021)There is a strong need to utilize jellyfish biomass in both economic and ecological way. These two aspects rely on the capability of jellyfish to bloom in large quantities and on accurate prediction on where and when ... -
Identification of a candidate dwarfing gene in Pallas, the first commercial barley cultivar generated through mutational breeding
(Peer reviewed; Journal article, 2023)Many induced mutants are available in barley (Hordeum vulgare L.). One of the largest groups of induced mutants is the Erectoides (ert) mutants, which is characterized by a compact and upright spike and a shortened culm. ... -
Identification of different antennal-lobe neuron categories;: a morphological and physiological study of second order neurons in the primary olfactory brain centre of the moth Heliothis virescens
(Master thesis, 2014)Olfaction is the sense of smell, first mediated by specialized sensory cells in the sensilla hair covering the moth antennae, projecting to the primary olfactory centre the antennal lobe. From this first synaptic level the ... -
Identification of Marine Organisms using Chemotaxonomy and Hyperspectral Imaging
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:292, Doctoral thesis, 2013)In this study, pigment composition in marine organisms has been investigated for different purposes. The absorption spectra of pigments from a given organism give us an optical fingerprint for that particular organism when ... -
Identification of tolerance levels on the coldwater coral Desmophyllum pertusum (Lophelia pertusa) from realistic exposure conditions to suspended bentonite, barite and drill cutting particles
(Peer reviewed; Journal article, 2022)Cold-water coral (CWC) reefs are numerous and widespread along the Norwegian continental shelf where oil and gas industry operate. Uncertainties exist regarding their impacts from operational discharges to drilling. Effect ... -
Identification, mapping, and photobiology of Arctic macro- and microalgae using ROV-UHI
(Doctoral theses at NTNU;2024:237, Doctoral thesis, 2024)This thesis comprises firstly of method development, using a newly developed remotely operated vehicle carrying an underwater hyperspectral imaging camera (mini-ROV-UHI) for identification and mapping of brown, green and ... -
Identifikasjon av ukjente legemidler og misbruksstoffer ved spektersøk på GCMS ved bruk av deconvolution software
(Master thesis, 2009)Hensikt og problemstilling: Gasskromatografi-massespektrometri (GCMS) brukes ofte i laboratorier som utfører toksikologisk screening etter legemidler, giftstoffer og misbruksstoffer i biologiske prøver. Det kan imidlertid ... -
Identifying Conservative Criteria for (environmental) Assessments of Vulnerability;: Seabirds and Offshore Wind Farms as a Case Study
(Master thesis, 2013)The approach is based on four criterias; 1) elasticity of adult and juvenile survival on population growth rate, 2) redlist status and 3) local abundances and 4) flight properties. I also investigated whether the different ... -
IIb-RAD-sequencing coupled with random forest classification indicates regional population structuring and sex-specific differentiation in salmon lice (Lepeophtheirus salmonis)
(Peer reviewed; Journal article, 2022)The aquaculture industry has been dealing with salmon lice problems forming serious threats to salmonid farming. Several treatment approaches have been used to control the parasite. Treatment effectiveness must be optimized, ... -
IL-1β og TNF-α indusert genuttrykk av DKK1 og OPG involverer cPLA2-IVα i SW-982 synoviocytter
(Master thesis, 2011)I denne studien har det blitt sett nærmere på cPLA2 sin rolle i reguleringen av signalsporene RANK/RANKL/OPG signalsystemet og Wnt-signalisering ved å detektere og kvantifisere genuttrykket av reseptor aktivator av nukleær ... -
Illustrating the Potential of Ulva sp.: Development of an Explorative Model for the Multiculture of Ulva sp. and Littorina littorea in a Recirculating Aquaculture System (RAS) Waste Stream
(Master thesis, 2022)The cultivation of seaweed species in fishpond effluent, characterized by high ammonium concentrations, has shown to successful and often high removal efficiencies can be attained. However, the high nitrate concentration ... -
The imaging of guard cells of thioglucosidase (tgg) mutants of Arabidopsis further links plant chemical defence systems with physical defence barriers
(Journal article; Peer reviewed, 2021)The glucosinolate-myrosinase system is a well-known plant chemical defence system. Two functional myrosinase-encoding genes, THIOGLUCOSIDASE 1 (TGG1) and THIOGLUCOSIDASE 2 (TGG2), express in aerial tissues of Arabidopsis. ... -
Immigration counter-acts local micro-evolution of a major fitness component: migration-selection balance in free-living song sparrows
(Peer reviewed; Journal article, 2021)Ongoing adaptive evolution, and resulting “evolutionary rescue” of declining populations, requires additive genetic variation in fitness. Such variation can be increased by gene flow resulting from immigration, potentially ... -
Immobilisering og radiomerking av elg på Vega, 1992-2010 : konsekvenser for dyrevelferd, kondisjon, reproduksjon og overlevelse
(NINA rapport;658, Research report, 2011)For å kunne forstå dynamikken i bestander av jaktbare viltarter er det ofte nødvendig å merke et visst antall dyr for å innhente informasjon om individuell overlevelse, reproduksjon, kondisjon og atferd. Både merkeprosessen ... -
Immune gene expression and epigenetic potential affect the consumption of risky food by female house sparrows
(Peer reviewed; Journal article, 2024)When organisms move into new areas, they are likely to encounter novel food resources. Even if they are nutritious, these foods can also be risky, as they might be contaminated by parasites. The behavioural immune system ... -
