Total triiodothyronine and glucocorticoid metabolite levels in faecal samples are independent of colour morph in the Arctic fox (Vulpes lagopus)
(Master thesis, 2023)Arktiske dyr har ofte fysiologiske tilpasninger som muliggjør at de kan håndtere både ekstreme og varierende miljøforhold gjennom året. Det har blitt foreslått at fenotype for pelsfarge kan være basisen for de miljøforholdene ... -
Toward adaptive robotic sampling of phytoplankton in the coastal ocean
(Journal article; Peer reviewed, 2019)Currents, wind, bathymetry, and freshwater runoff are some of the factors that make coastal waters heterogeneous, patchy, and scientifically interesting—where it is challenging to resolve the spatiotemporal variation within ... -
Towards a circular phosphorus economy in Norway - Strategies for integrating agriculture and aquaculture at multiple scales
(Research report, 2023)Phosphorus is a building block for all life and therefore plays an essential role in food production. Currently, large amounts of phosphorus enter the Norwegian food system from abroad in the form of mineral fertilizer, ... -
Towards a future without stocking: harvest and river regulation determine long-term population viability of migratory salmonids
(Peer reviewed; Journal article, 2021)Freshwater species are particularly vulnerable to emerging threats linked to climate change because they are often already heavily impacted by habitat destruction, pollution, and exploitation. For many harvested populations ... -
Towards a predictive conservation biology: the devil is in the behaviour
(Peer reviewed; Journal article, 2019)One of the most important challenges in conservation biology is to predict the viability of populations of vulnerable and threatened species. This requires that the demographic stochasticity strongly affecting the ecological ... -
Towards a unifying pan-arctic perspective: A conceptual modelling toolkit
(Peer reviewed; Journal article, 2020)The Arctic Ocean is overwhelmingly forced by its lateral boundaries, and interacts with, the global system. For the development of nested conceptual models of the Arctic Ocean ecosystem we here choose the full pan-Arctic ... -
Towards harmonisation of chemical monitoring using avian apex predators: Identification of key species for pan-European biomonitoring
(Peer reviewed; Journal article, 2020)Biomonitoring in raptors can be used to study long-term and large-scale changes in environmental pollution. In Europe, such monitoring is needed to assess environmental risks and outcomes of chemicals regulation, which is ... -
Towards logical modeling of disease mechanisms as a tool for therapy design
(Doctoral theses at NTNU;2024:191, Doctoral thesis, 2024)Precision medicine aims to tailor medical interventions to individual patient characteristics, recognizing the inherent diversity in biological responses. At the core of this approach lies the imperative to move beyond ... -
Towards rainy Arctic winters: effects of experimental icing on tundra plants and their soil conditions
(MET report;, Research report, 2019)Global warming comes with more frequent extreme climate events. In the Arctic, extreme warm spells with heavy rain-on-snow events in winter can cause dramatic changes to the snow-pack and encapsulate the vegetation in thick ... -
Towards the production of genetically modified strawberries which are acceptable to consumers
(Journal article; Peer reviewed, 2011)This manuscript discusses different aspects that are relevant to genetically modified strawberry plants with improved characteristics and ‘acceptable’ to consumers and growers of strawberry. It starts with a consumer ... -
Toxic algal bloom induced by ocean acidification disrupts the pelagic food web
(Journal article; Peer reviewed, 2018)Ocean acidification, the change in seawater carbonate chemistry due to the uptake of anthropogenic CO2, affects the physiology of marine organisms in multiple ways1. Diverse competitive and trophic interactions transform ... -
Toxic and essential elements in seafood from Mausund, Norway
(Journal article, 2017)In annual surveys conducted during the period 2012–2015, concentrations of the toxic or essential elements B, Se, Cd, Sn, Cs, Hg, Pb, Al, Cr, Mn, Fe, Ni, Cu, Zn, and As were analyzed in brown meat of edible crab (Cancer ... -
Toxic and Genotoxic Effects of Fast Pyrolysis Oils Generated from Three Different Feedstocks Evaluated in an Allium cepa Chromosome Aberration Assay
(Master thesis, 2014)Non-renewable energy sources cover the majority of today s energy demand. However, due to uncertainty of available petroleum reserves and great environmental impacts associated with the use of petroleum, renewable energy ... -

Toxic effects of a petroleum-based and a biodegradable MP on Daphnia magna
(Master thesis, 2022)Plast er vedvarende og allestedsnærværende på land og i akvatiske habitater. Mikroplast (MP; plastpartikler < 5 mm) fragmenteres vanligvis fra større plastbiter på grunn av for eksempel UV-stråling. Tidligere studier viser ... -
Toxicity and developmental effects of Arctic fuel oil types on early life stages of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2021)Due to the heavy fuel oil (HFO) ban in Arctic maritime transport and new legislations restricting the sulphur content of fuel oils, new fuel oil types are continuously developed. However, the potential impacts of these new ... -
Toxicity and Genotoxicity of five pyrolytic Bio-Oils produced from Wood, measured as Root Growth Inhibition and DNA Double-Strand Breaks in Allium cepa
(Master thesis, 2014)Pyrolytic bio-oil is considered as a potential renewable energy resource that might replace fossil fuels in the future. Chemically, bio-oils are highly complex mixtures consisting of several hundred different compounds, ... -
Toxicity of microplastics and natural particles in the freshwater dipteran Chironomus riparius: Same same but different?
(Journal article; Peer reviewed, 2019)Microplastics (MP) are contaminants of emerging concern in aquatic ecosystems. While the number of studies is rapidly increasing, a comparison of the toxicity of MP and natural particulate matter is largely missing. In ... -
Toxicogenomics of Aryl Hydrocarbon- and Estrogen Receptor Interactions in Fish: Mechanisms and Profiling of Gene Expression Patterns in Chemical Mixture Exposure Scenarios
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:264, Doctoral thesis, 2007)Almost without exception, biological processes such as overt morphological changes, development (both reproductive and growth), toxicological responses and clinical manifestation to disease, have molecular basis. From our ... -
Trace element concentrations in feathers and blood of Northern goshawk (Accipiter gentilis) nestlings from Norway and Spain
(Journal article; Peer reviewed, 2017)Information on trace element pollution in the terrestrial environment and its biota is limited compared to the marine environment. In the present study, we collected body feathers and blood of 37 Northern goshawk (Accipiter ...
