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
(Peer reviewed; Journal article, 2021)Telomere length is predictive of adult health and survival across vertebrate species. However, we currently do not know whether such associations result from among-individual differences in telomere length determined ... -
Telomere dynamics and migration patterns in a long-distance migrant, the Arctic skua
(Master thesis, 2017)Telomeres are protective caps at the end of chromosomes that shorten with each cell cycle as well as by oxidative stress. In birds and mammals, telomeres shorten more slowly in long-lived species and, within species, those ... -
Temperature and salinity use of fjord migrating and estuarine resident veteran brown trout (Salmo trutta) in a fjord system in northern Norway
(Master thesis, 2021)Det er allment akseptert at temperatur og salinitet er viktige abiotiske faktorer som påvirker ulike aspekter av anadrom brunørret (Salmo trutta) sin livssyklus. Detaljert kunnskap om bruken av ulike temperaturer og ... -
Temperature synchronizes temporal variation in laying dates across European hole-nesting passerines
(Peer reviewed; Journal article, 2022)Identifying the environmental drivers of variation in fitness-related traits is a central objective in ecology and evolutionary biology. Temporal fluctuations of these environmental drivers are often synchronized at large ... -
Temporal and Spatial Variation in Correspondence between Climate Proxies and Recorded Climate Data
(Master thesis, 2015)Knowledge about effects of regional climate variation on the vegetation is important and will provide more insight into the impacts of global climate change. Tree growth and Normalized Difference Vegetation Index (NDVI) ... -
Temporal and spatial variation in juvenile roe deer body mass
(Master thesis, 2020)Kroppsvekt tidlig i livet kan være en god indikator for hvor godt et individ vil gjøre det senere i livet. Det er derfor viktig å forstå de forskjellige mekanismene som påvirker kroppsvekt. Værforhold kan ha stor effekt ... -
Temporal and spatial variation in prevalence of the parasite Syngamus trachea in a metapopulation of House Sparrows (Passer domesticus)
(Journal article, 2013)When investigating parasite–host dynamics in wild populations, a fundamental parameter to investigate is prevalence. This quantifies the percentage of individuals infected in the population. Investigating how prevalence ... -
Temporal Change and Effects of Perfluoroalkyl Substanses (PFASs) on Thyroid Hormone Levels in Mother-Cub Pairs of Polar Bear (Ursus maritimus) from Svalbard in 1998 and 2008
(Master thesis, 2011)High levels of persistent organic pollutants (POPs) have been detected in the Arctic wildlife. While many of the traditional POPs have been reported to decline the last decades, emerging contaminants such as perfluoroalkyl ... -
Temporal changes in DNA methylation and RNA expression in a small song bird: within- and between-tissue comparisons

Temporal correlations among demographic parameters are ubiquitous but highly variable across species
(Peer reviewed; Journal article, 2022)Temporal correlations among demographic parameters can strongly influence population dynamics. Our empirical knowledge, however, is very limited regarding the direction and the magnitude of these correlations and how they ... -

Temporal dynamics of carbon sequestration in coastal North Atlantic fjord system as seen through dissolved organic matter characterisation
(Peer reviewed; Journal article, 2021)Fjord systems in higher latitudes are unique coastal water ecosystems that facilitate the study of dissolved organic matter (DOM) dynamics from surface to deeper waters. The current work was undertaken in the Trondheim ... -
Temporal trends of legacy organochlorines in different white-tailed eagle (Haliaeetus albicilla) subpopulations: A retrospective investigation using archived feathers
(Peer reviewed; Journal article, 2020)Understanding the spatiotemporal patterns of legacy organochlorines (OCs) is often difficult because monitoring practices differ among studies, fragmented study periods, and unaccounted confounding by ecological variables. ...
