System responses to equal doses of photosynthetically usable radiation of blue, green, and red light in the marine diatom Phaeodactylum tricornutum
(Journal article; Peer reviewed, 2014)Due to the selective attenuation of solar light and the absorption properties of seawater and seawater constituents, free-floating photosynthetic organisms have to cope with rapid and unpredictable changes in both intensity ... -
Systematic review of toxicity removal by advanced wastewater treatment technologies via ozonation and activated carbon
(Journal article; Peer reviewed, 2019)Upgrading wastewater treatment plants (WWTPs) with advanced technologies is one key strategy to reduce micropollutant emissions. Given the complex chemical composition of wastewater, toxicity removal is an integral parameter ... -
Systematic revision of Chone Krøyer, 1856, Dialychone Claparède, 1870 and Paradialychone Tovar-Hernández, 2008 (Sabellidae: Annelida) in Norwegian waters
(Master thesis, 2018)The species of Chone, Dialychone and Paradialychone (Sabellidae: Annelida) in Norwegian waters are assessed using morphological and molecular data. The monophyly of Chone, Dialychone, Paradialychone and Euchone is tested ... -
Systematically controlled decomposition mechanism in phosphorus flame retardants by precise molecular architecture
(Journal article; Peer reviewed, 2019)Flame retardants (FR) are inevitable additives to many plastics. Halogenated organics are effective FRs but are controversially discussed due to the release of toxic gases during a fire or their persistence if landfilled. ... -
Systematics and evolutionary history of Tanytarsus van der Wulp, 1874 (Diptera: Chironomidae)
(Doctoral theses at NTNU;2017:201, Doctoral thesis, 2017)On the evolution and diversity of Tanytarsus non-biting midges / Evolusjon og mangfold hos fjærmygg i slekten Tanytarsus As species are the fundamental unit of biodiversity, accurate species identification and delimitation ... -
Systems biology graphical notation markup language (SBGNML) version 0.3
(Peer reviewed; Journal article, 2020)This document defines Version 0.3 Markup Language (ML) support for the Systems BiologyGraphical Notation (SBGN), a set of three complementary visual languages developed for biochemists, mod-elers, and computer ... -
Systems Biology Graphical Notation: Process Description language Level 1 Version 2.0
(Journal article; Peer reviewed, 2019)The Systems Biology Graphical Notation (SBGN) is an international community effort that aims to standardise the visualisation of pathways and networks for readers with diverse scientific backgrounds as well as to support ... -
Systems toxicology approach for evaluating the effects of contaminants on fish ovarian development and reproductive endocrine physiology: A combination of field-, in vivo and ex vivo studies using Atlantic cod (Gadus morhua)
(Doctoral theses at NTNU, 2021:102, Doctoral thesis, 2021)Human activities contribute a significant amount of contaminants to the natural environment. Polycyclic aromatic hydrocarbons (PAHs) and per- and polyfluoroalkyl substances (PFASs) are example of contaminants that threaten ... -
Taking a trip to the shelf: Behavioral decisions are mediated by the proximity to foraging habitats in the black-legged kittiwake
(Journal article; Peer reviewed, 2017)For marine top predators like seabirds, the oceans represent a multitude of habitats regarding oceanographic conditions and food availability. Worldwide, these marine habitats are being altered by changes in climate and ... -
Target tissue toxicity of the thyroid hormone system in two species of arctic mammals carrying high loads of organohalogen contaminants
(Doctoral thesis at NTNU;2014:330, Doctoral thesis, 2014)Background: Arctic marine top predators such as the hooded seals (Cystophora cristata) and polar bears (Ursus maritimus) are exposed to and bioaccumulate high levels of lipophilic organohalogen contaminants (OHCs) through ... -
Targeted mutagenesis of Δ5 and Δ6 fatty acyl desaturases induce dysregulation of lipid metabolism in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2020)Background With declining wild fish populations, farmed salmon has gained popularity as a source for healthy long-chain highly unsaturated fatty acids (LC-HUFA). However, the introduction of plant oil in farmed salmon ... -
Targeting Cytosolic Phospholipase A2 alpha (cPLA2α) in Hematological Cancers and Inflammation
(Doctoral theses at NTNU;2023:409, Doctoral thesis, 2023)Cytosolic phospholipase A2 alpha (cPLA2α) is an enzyme that plays a crucial role in regulating the balance between cellular growth and death by releasing the unsaturated fatty acid arachidonic acid from membrane lipids. ... -
Taxonomy and conservation status of hawk-eagles (Genus Nisaetus) in south-east Asia
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:91, Doctoral thesis, 2006)Morphological, vocal and molecular data have been used to reevaluate the taxonomy of some Asian Nisaetus taxa. This name is used instead of Spizaetus because the latter genus is polyphyletic with clades in Asia, South ... -
Teatime for termites: Understanding the impact of human land-use and climate on termite and microbial litter decomposition
(Master thesis, 2019)Nedbrytning av planter er en fundamental underliggende prosess for næringssyklus og økosystemproduktivitet. Nedbrytningshastigheten i savanneøkosystemene er avhengige av både jordmikrober og makrofauna, hvor termitter er ... -
Teatime in the Serengeti: macrodetritivores sustain recalcitrant plant litter decomposition across human-modified tropical savannahs
(Peer reviewed; Journal article, 2020)Background and aims Intensification of savannah land-use is predicted to negatively influence soil biodiversity and functioning such as litter decomposition by detritivores. Loss of macrodetritivores, particularly termites, ... -
Telomere attrition rates are associated with weather conditions and predict productive lifespan in dairy cattle
