Stochastic model of mating decision control in yeast through the scaffold protein Ste5
(Master thesis, 2013)High throughput technologies in genetics laid the foundations for systems and synthetic biology. Systems and synthetic biology became an important topic in biology research. It was used in research to investigate the ... -
Stochastic modeling of finite populations with individual heterogeneity in vital parameters
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:204, Doctoral thesis, 2010)Natural populations show large variation among individuals in patterns of survival and reproduction over time, that can often be associated with differences in state variables such as age, size or spatial location. Some ... -
Stochastic Modeling of Mating Systems and their Effect on Population Dynamics and Genetics
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:94, Doctoral thesis, 2011) -
Stochastic rain events increase NDVI through moss water content: a High-Arctic field experiment
(Master thesis, 2019)Målinger av ”Normalized Difference Vegetation Index” (NDVI) gjennom fjernmålinger blir brukt til å indikere produktiviteten til vegetasjonen i Høyarktis, og hvordan den påvirkes av klimaendringer. Tolkningen av observerte ... -
Stochastic variation in gut bacterial community affects reproductive rates in the water flea Daphnia magna
(Peer reviewed; Journal article, 2022)It is well-documented that perturbation of the gut bacterial community can influence the reproductive rates of the host. Less is known about how natural ecological processes can change the bacterial composition in the gut ... -
Strategies to Enhance Logic Modeling-Based Cell Line-Specific Drug Synergy Prediction
(Journal article; Peer reviewed, 2020)Discrete dynamical modeling shows promise in prioritizing drug combinations for screening efforts by reducing the experimental workload inherent to the vast numbers of possible drug combinations. We have investigated ... -
Stress gives less?: Cortisol effects on E2 induced vitellogenin expression in salmon hepatocytes
(Master thesis, 2010)The Atlantic salmon (Salmo salar) is an important species in the fish farming industry in several countries. As high production volume is wanted, a corresponding survival rate of the fry is required. To ensure the development ... -
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. -
