Thyroid hormone disruptive effects of environmental contaminants in free-ranging brown trout (Salmo trutta) from lake Mjøsa, Norway
(Master thesis, 2011)VBrown trout (Salmo trutta) from Lake Mjøsa, Norway, contain very high levels of polybrominated diphenyl ethers (PBDEs), in addition to elevated levels of other persistent organic pollutants (POPs) and trace metals, including ... -
Thyroid hormone status and thyroid gland histology in PFAS- and mercury contaminated glaucous gulls (Larus hyperboreus) from Svalbard
(Master thesis, 2018)The glaucous gull (Larus hyperboreus) is a scavenger and top predator in the Arctic marine food web. Due to its high trophic position, it is highly exposed to organohalogenated compounds (OHCs) and metals originating from ... -
Thyroid hormones correlate with basal metabolic rate but not field metabolic rate in a wild bird species
(Journal article; Peer reviewed, 2013)Thyroid hormones (TH) are known to stimulate in vitro oxygen consumption of tissues in mammals and birds. Hence, in many laboratory studies a positive relationship between TH concentrations and basal metabolic rate (BMR) ... -
Tilrettelegging for dyrking av butare i Trøndelag.
(Research report, 2014)Butare Alaria esculenta er en av de store tareartene som vokser langs Trøndelagskysten og som er attraktiv å begynne å dyrke med tanke på anvendelse til flere ulike produkter. Den vokser raskt, produserer mye biomasse og ... -
Tiltak for reduksjon av termisk stress og økt arbeidskomfort hos smelteverksarbeidere - Et felt- og laboratoriestudie
(Master thesis, 2017)Masteravhandlingen vil bli skrevet i forbindelse med SINTEF Teknologi og samfunn, avdeling Helse sitt prosjekt Fremtidens vernebekledning for smelteverksarbeidere og skal utvikle et kunnskapsgrunnlag for test og utvikling ... -
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 ... -
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 ... -
