Time kinetics of fatty acids changes in total lipids and phospholipids of A. franciscana following enrichment and starvation, with a main focus on docosahexaenoic acid (DHA)
(Master thesis, 2013)HUFA in PL has been considered to be easily digested by marine fish larvae, which will result in better growth, survival and development (e.g., pigmentation, stress resistance and gut maturation). As one of the most commonly ... -
Time since divergence between the blue whiting sister species Micromesistius poutassou and M. australis
(Master thesis, 2010)The Micromesistius genus consists of two commercially important species, M. poutassou found in the Northern Hemisphere and M. australis in the Southern Hemisphere. Genetic variation between and within the species was ... -
Time-series of Phytoplankton Photosynthesis and Dynamics using PHYTO-PAM and Autonomous Underwater Vehicle
(Master thesis, 2011)This MSc thesis comprises PHYTO-PAM measurements of phytoplankton photosynthesis, measured as electron transfer rates in order to study photosynthetic dynamics. Time-series of photosynthesis from two phytoplankton bloom ... -
Timing is everything: Survival of Atlantic salmon Salmo salar postsmolts during events of high salmon lice densities
(Peer reviewed; Journal article, 2020)Atlantic salmon in aquaculture act as reservoir hosts and vectors of parasites like salmon lice and this parasite is shown to harm wild salmonid populations. In this study, n = 29,817 tagged Atlantic salmon were studied ... -
Timing of homing migration of anadromous brown trout, Arctic char and Atlantic salmon in two rivers in Northern Norway.
(Master thesis, 2021)Brunørret (Salmo trutta), Arktisk røye (Salvelinus alpinus) og Atlanterhavslaks (S. salar) kan begi seg ut på marine næringsmigrasjoner. Men, tiden de bruker i havet og tidspunktet for tilbakevandring til elva varierer ... -
To Adapt or Not Adapt: Assessing the Adaptive Capacity of Artisanal Fishers in the Trondheimsfjord (Norway) to Jellyfish (Periphylla periphylla) Bloom and Purse Seiners
(Journal article; Peer reviewed, 2015)Worldwide increases of jellyfish has occurred during the last several decades. A dense population of a large scyphozoan jellyfish, Periphylla periphylla, has established itself as top predator in the Trondheimsfjord in ... -
Toleranse og adferdsresponser hos skotteluslarver (Caligus elongatus) ved eksponering for ulike saliniteter
(Master thesis, 2024)Caligus elongatus, også kjent som skottelus, har blitt rapportert som et økende velferdsproblem i norsk oppdrett de siste årene. Mange oppdrettslokaliteter er lokalisert der saliniteten i det øvre vannlaget varierer, og ... -
Too Much of a Good Thing: Photoprotection in Boreal Conifers During Winter
(Master thesis, 2013)Photochemical utilization of light energy is inhibited in boreal conifers during winter and spring because the carbon fixation reactions slow down due to low temperature. Incoming light can be very strong due to reflection ... -
Topographic complexity and biotic resilience to climate change
(Master thesis, 2013)Topographically complex alpine terrains create a mosaic of diverse microclimates over short distances. This study investigated the extent of small-scale variation in temperature and soil moisture using dense arrays of ... -

Topsoil restoration of three construction sites in central Norway: Comparing restoration outcome by species composition and soil characteristics in relation to three reference communities
(Master thesis, 2023)Økologisk restaurering er et verktøy som kan brukes til å lette det uunngåelige presset som bygging av infrastruktur medfører på vårt landskap og natur. I denne studien gjennomførte jeg en analyse av artssammensetning og ... -
Torpor arousal rates in northern bats (Eptesicus nilssonii)
(Master thesis, 2022)Endoterme dyr holder ofte kroppstemperaturen sin høy og stabil i møte med mange miljøbetingelser, noe som krever mye energi. For å unngå energiutfordringene bruker mange pattedyr torpor, en prosess hvor kroppstemperatur, ... -
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 ...
