Perfluoroalkyl substances are positively correlated with triiodothyronine concentrations, but not metabolic rate in breeding arctic terns (Sterna paradisaea)
(Master thesis, 2021)Perfluorerte alkylstoffer (PFAS) er allestedsnærværende miljøgifter, hvorav mange er svært persistente. Forskning tyder på at denne kjemikaliegruppen har tyroidhormonforstyrrende egenskaper og mulige effekter på metabolismen ... -
The persistent effects of corticosterone administration during lactation on the physiology of maternal and offspring mitochondria
(Journal article; Peer reviewed, 2022) -
Persistent organic pollutants and organophosphate esters in feathers and blood plasma of adult kittiwakes (Rissa tridactyla) from Svalbard – associations with body condition and thyroid hormones
(Journal article; Peer reviewed, 2018)Polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), organochlorine pesticides (OCPs) and organophosphate esters (OPEs) were assessed in blood plasma and feathers of 19 adult black-legged kittiwakes ... -
Persistent organic pollutants, skull size and bone density of polar bears (Ursus maritimus) from East Greenland 1892-2015 and Svalbard 1964-2004.
(Journal article; Peer reviewed, 2017)We investigated skull size (condylobasal length; CBL) and bone mineral density (BMD) in polar bears (Ursus maritimus) from East Greenland (n = 307) and Svalbard (n = 173) sampled during the period 1892–2015 in East Greenland ... -
Personality and Innovation in House Sparrows - Evolutionary and Demographic Consequences of Individual Phenotypic Differences
(Master thesis, 2015)Atferdssyndromer, og kovarians mellom trekk er essensielle for forståelse av fenotypisk struktur og fenotypisk variasjon. Nyere forskning viser at atferdssyndromer ikke bare eksisterer, men at disse varierer i struktur ... -
Personality and pace-of-life behavioral syndromes in a model species, the House Sparrow (Passer domesticus)
(Master thesis, 2016)Consistent individual differences in behaviour ( animal personality ) may be favoured by natural selection because they are driven by adaptive differences in life-history and physiology traits, constituting a pace-of-life ... -
PFOS mediates immunomodulation in an avian cell line that can be mitigated via a virus infection
(Journal article; Peer reviewed, 2019)Background Per- and polyfluoroalkyl substances (PFASs) are environmentally persistent and bioaccumulative chemicals. Immunomodulation is among the most concerning of toxic effects linked with PFAS exposure in mammalian ... -
Phenanthrene Bioavailability and Toxicity to Daphnia magna in the Presence of Carbon Nanotubes with Different Physicochemical Properties
(Journal article; Peer reviewed, 2016)Studies investigating the effect of carbon nanotubes (CNTs) on the bioavailability and toxicity of hydrophobic organic compounds in aquatic environments have generated contradictory results, and the influence of different ... -
Phenotypic and genotypic divergence of plant–herbivore interactions along an urbanization gradient
(Peer reviewed; Journal article, 2022)Urban environments provide challenging conditions for species survival, including increased temperatures, drought and pollution. Species can deal with these conditions through evolution across generations or the immediate ... -
Phenylalanine Hydroxylase RNAi Knockdown Negatively Affects Larval Development, Molting and Swimming Performance of Salmon Lice
(Peer reviewed; Journal article, 2020)Phenylalanine hydroxylase (PAH) is a crucial enzyme involved in tyrosine biosynthesis, having roles in neurological and physiological processes. The purpose of PAH has received little attention in crustaceans despite ... -
Phospholipids in Atlantic cod (Gadus morhua L.) larvae rearing: Incorporation of DHA in live feed and larval phospholipids and the metabolic capabilities of larvae for de novo synthesis
(Doctoral thesis at NTNU;2015:257, Doctoral thesis, 2015) -
Phosphorus in Palmaria palmata: Uptake, storage and potential recycling in IMTA
(Master thesis, 2023)I fremtiden kommer tilgangen til fosfor å være i stadig begrenset tilgang, siden den blir hentet ut fra begrensede reserver. Fosfor er avgjørende for produksjon av kunstgjødsel for bruk i landbruk, og er derfor på sikt ... -
Phosphorus limitation in Rhodomonas baltica and the effects as food resource on Calanus finmarchicus reared at elevated temperatures
(Master thesis, 2021)Elevation in water temperature due to the climate change is considered one of the major factors to influence the microalgae and zooplankton community. The copepod genus Calanus is ecologically important as an energy bridge ... -
Photoacclimation mechanismsand light responses in marine micro- and macroalgae
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:74, Doctoral thesis, 2014)Photoacclimation mechanisms and light responses in marine micro- and macroalgae Marine diatoms play a fundamental role in marine ecosystems and on global climate, as they fix more CO2 and release more oxygen than all ... -
Photobioreactor time-series of a simulated bloom of Emiliania huxleyi
(Master thesis, 2009) -
Photoperiodism and overwintering in boreal and sub-Arctic Calanus finmarchicus populations
(Journal article, 2023)ABSTRACT: The copepod Calanus finmarchicus, a key species in the North Atlantic, generally spends the non-productive season by descending into deep waters and entering diapause, a physiological state characterized by reduced ... -
Photophysiological cycles in Arctic krill are entrained by weak midday twilight during the Polar Night
(Peer reviewed; Journal article, 2021)Light plays a fundamental role in the ecology of organisms in nearly all habitats on Earth and is central for processes such as vision and the entrainment of the circadian clock. The poles represent extreme light regimes ... -
Photophysiologically active green, red, and brown macroalgae living in the Arctic Polar Night
(Peer reviewed; Journal article, 2023)Abstract: Arctic macroalgae species have developed different growth strategies to survive extreme seasonal changes in irradiance in polar regions. We compared photophysiological parameters such as the light saturation ... -
Photosynthetic Response to increasing Temperatures - a Comparison between prostrate and erect alpine Shrubs
(Master thesis, 2015)As a response to climate change, shrub biomass has increased in alpine and arctic tundra ecosystems. Substantial shrub encroachment can lead to changes in carbon fluxes, due to a shift in community compositions and functional ...
