Stress responses induced by temperature and light conditions in Brassica napus
(Master thesis, 2015)Brassica napus, also known as oilseed rape or canola, belongs to the family Brassicaceae. An important characteristic of Brassicaceae is the production of specific secondary metabolites, glucosinolates. Intact glucosinolates ... -
Stress responses to repeated captures in a wild ungulate
(Peer reviewed; Journal article, 2022)While capture-mark-recapture studies provide essential individual-level data in ecology, repeated captures and handling may impact animal welfare and cause scientific bias. Evaluating the consequences of invasive methodologies ... -
Strong migratory connectivity across meta-populations of sympatric North Atlantic seabirds
(Peer reviewed; Journal article, 2021)Identifying drivers of population trends in migratory species is difficult, as they can face many stressors while moving through different areas and environments during the annual cycle. To understand the potential of ... -
Structure of the G-matrix in relation to phenotypic contributions to fitness
(Peer reviewed; Journal article, 2021)Classical theory in population genetics includes derivation of the stationary distribution of allele frequencies under balance between selection, genetic drift, and mutation. Here we investigate the simplest generalization ... -
Structure, dynamics, and regeneration capacity at the sub-arctic forest-tundra ecotone of northern Norway and Kola Peninsula, NW Russia
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:230, Doctoral thesis, 2013) -
Strømme syndrom - Jakten på et gen
(Master thesis, 2011)I 2005 ble en ny type sekvenseringsteknologi introdusert som åpnet for uante muligheter innen genetikken. Prosjekter som tidligere ble ansett som uoverkommelige, både teknisk og økonomisk, kan nå gjennomføres. Sekvenseri ... -
Studies of Insulin and Cytokine Regulation of Fatty Acid Desaturases, FOXO3A and FOXO3A Target Genes in THP-1 Monocytes
(Master thesis, 2012)The increase of obesity that we have experienced during the last decades and its association with insulin resistance, type 2 diabetes and other metabolic diseases has resulted in an enormous interest for understanding the ... -
Studies of light responses and the development of a transformation system for the benthic diatom Seminavis robusta
(Master thesis, 2014)Diatoms are a divergent group of organisms with a complex evolutionary background, and belong to the Heterokonta group phylogenetically. Diatoms have gone through several endosymbiotic processes with both green algae and ... -
Studies on antifreeze proteins
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:98, Doctoral thesis, 2005)Antifreeze proteins (AFPs) are produced by a variety of so-called freeze-avoiding animals, ectotherms that adaptively allow their body fluids to supercool as a response to subfreezing temperatures in their environment. ... -
Studies on Echinodermata from the NE Atlantic Ocean - Spatial distribution and abundance of Asteroidea, including taxonomic and molecular studies on Crossaster and Henricia genera - Value-chain results, including test fishery, biology, market and nutritional analysis on Parastichopus tremulus (Holothuroidea) from the Norwegian coast
(Doctoral theses at NTNU;2021:254, Doctoral thesis, 2021)The phylum Echinodermata represent a large part of the marine benthic ecosystem biomass (up to 90%), and are also important in determining habitat structure for other species, and maintaining high species diversity in the ... -
Studies on genus Aneura (Marchantiophyta, Aneuraceae): typification of Riccardia fuscovirens Lindb.
(Peer reviewed; Journal article, 2022)Riccardia fuscovirens Lindb. is lectotypified and the lectotype is described. It is morphologically very similar to Aneura pinguis and provisionally regarded as synonym to it. -
Study of 293 endo cells and human islets of Langerhans in capsules of epimerized alginate
(Master thesis, 2009)Alginate is a polysaccharide found in nature as structural component in marine brown algae and as capsular polysaccharide in some soil bacteria. Alginates have the potential to work as immobilization material for cells, ... -
Study of HIPP25, HIPP26, HIPP27 gene expression and glucosinolate content in Arabidopsis thaliana and Noccaea caerulescens upon heavy metal treatments
(Master thesis, 2017)Hyperaccumulator plant species accumulate exceedingly high concentrations of metals in aerial parts and are increasingly studied because of their potential for cleaning up land contaminated with heavy metals. One such ... -
Studying attractiveness and defense responses of Brassica napus transgenic MINELESS plants to insects for pest management
(Master thesis, 2014)Glucosinolate myrosinase system is well-established defense mechanism against insect herbivores feed on plants from Brassicaceae family. This defense mechanism is also known as the mustard oil bomb which bring myrosinase ... -
Subclinical thiamine deficiency results in failed reproduction in Arctic foxes
(Peer reviewed; Journal article, 2024)Thiamine deficiency can result in life-threatening physiological and neurological complications. While a thiamine-deficient diet may result in the onset of such symptoms, the presence of thiaminase – an enzyme that breaks ... -
Subtle foodscape displacement of a native ungulate by free-ranging livestock in a forest agroecosystem
(Journal article; Peer reviewed, 2018)The prevalence of livestock grazing in wildlife area s is increasing. This transformation of ecosys- tems into agroecosystems is concerning because the intr oduction of new species may cause niche displacement of the ... -
A Successful Crowdsourcing Approach for Bird Sound Classification
(Peer reviewed; Journal article, 2023)Automated recorders are increasingly used in remote sensing of wildlife, yet automated methods of processing the audio remains challenging. Identifying animal sounds with machine learning provides a solution, but optimizing ... -
Successional dynamics in boreal forests: What is the impact of moose browsing, and which pathways are preferred by landowners?
(Master thesis, 2018)Norwegian boreal forests are usually managed for timber production, but also provide other ecosystem services, including game meat, income from hunting licenses, and recreational opportunities. Forest landowners values ... -
