Transcriptional regulation of lipid metabolism when salmon fry switches from endogenous to exogenous feeding
(Journal article; Peer reviewed, 2018)The onset of first feeding is a critical period for Atlantic salmon (Salmo salar). The fish goes through a dramatic transition, from using the yolk sac as an energy and nutrient resource to rely on exogenous food. However, ... -
Transcriptional regulatory networks in Arabidopsis thaliana during single and combined stresses
(Journal article; Peer reviewed, 2016)Differentially evolved responses to various stress conditions in plants are controlled by complex regulatory circuits of transcriptional activators, and repressors, such as transcription factors (TFs). To understand the ... -
Transgene-free genome editing in marine algae by bacterial conjugation - comparison with biolistic CRISPR/Cas9 transformation
(Journal article; Peer reviewed, 2018)The CRISPR/Cas9 technology has opened the possibility for targeted genome editing in various organisms including diatom model organisms. One standard method for delivery of vectors to diatom cells is by biolistic particle ... -
Transgenerational effects of short-term exposure to acidification and hypoxia on early developmental traits of the mussel Mytilus edulis
(Journal article; Peer reviewed, 2019)Transgenerational effects of multiple stressors on marine organisms are emerging environmental themes. We thus experimentally tested for transgenerational effects of seawater acidification and hypoxia on the early development ... -
Tree recruitment in the Forest-tundra Ecotone: Limitation and facilitation processes in contrasting climatic Regions
(Master thesis, 2012)Aim: The aim of this study was to analyse how abiotic and biotic constraint and facilitation agents determine tree recruitment in the alpine zone in climatically different regions as well as across species; Birch, pine and ... -
Tree thinking cannot taken for granted: challenges for teaching phylogenetics
(Journal article; Peer reviewed, 2008)Tree thinking is an integral part of modern evolutionary biology, and a necessary precondition for phylogenetics and comparative analyses. Tree thinking has during the 20th century largely replaced group thinking, de ... -
Triploid Atlantic salmon in aquaculture - Consequences for fish health and welfare under farming conditions
(VKM Report;2023:22, Research report, 2023) -
Triploid Atlantic salmon × brown trout hybrids have similar seawater growth and welfare issues as triploid Atlantic salmon, but both were heavier at harvest than their diploid counterparts
(Peer reviewed; Journal article, 2022)Interspecific hybridisation may improve the farm performance of sterile triploid salmonids via heterosis (i.e. hybrid vigour). We assessed growth over the final 293 days in seawater, and harvest quality, in diploid and ... -
Trophic control of the Daphnia longispina/galeata complex in lakes containing the invasive European whitefish (Coregonus lavaretus)
(Master thesis, 2023)Miljøtilstanden i ferskvannsøkosystemer endrer seg raskt i en negativ retning. Hovedårsaken er menneskelig aktivitet, og spesielt bekymringsverdig er den pågående nedgangen i biodiversitet. Ferskvannsarter dør ut i økende ... -
Trophy Hunting Versus Ecotourism as a Conservation Model? Assessing the Impacts on Ungulate Behaviour and Demographics in the Ruaha-Rungwa Ecosystem, Central Tanzania
(Journal article, 2018)Trophy hunting may influence wildlife populations in many ways, but these effects have received little consideration in many of Africa’s protected areas. We assessed the effects of trophy hunting on group size, behaviour, ... -
TRY plant trait database – enhanced coverage and open access
(Journal article; Peer reviewed, 2019)Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem ... -
Twilight foraging enables European shags to survive the winter across their latitudinal range
(Peer reviewed; Journal article, 2021)Species breeding at high latitudes face a significant challenge of surviving the winter. Such conditions are particularly severe for diurnal marine endotherms such as seabirds. A critical question is therefore what behavioural ... -
Two decades of increasing functional and phylogenetic richness in a mountaintop flora in central Norway
(Journal article; Peer reviewed, 2024)Questions: Analysing how multiple facets of biodiversity vary across space and time can help to predict the vulnerability of mountaintop floras to future environmental changes. Here we addressed the following questions: ... -
Two-current choice flumes for testing avoidance and preference in aquatic animals
(Journal article; Peer reviewed, 2016)1. Aquatic chemical ecology is an important and growing field of research that involves understanding how organisms perceive and respond to chemical cues in their environment. Research assessing the preference or avoidance ... -
Typification of Jungermannia pinguis L. (Marchantiophyta, Aneuraceae)
(Peer reviewed; Journal article, 2023) -
Ultrasonic imaging as a means of monitoring gonadal development in lumpfish (Cyclopterus lumpus)
(Peer reviewed; Journal article, 2023)The commercial farming of juvenile lumpfish requires monitoring of gonadal development to achieve synchronized production. Conventional methods such as gonadosomatic index (GSI), sex hormone analyses, gonadal histology, ... -
Ultrasound as a non-invasive tool for monitoring reproductive physiology in female Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2018)Aiming to explore ultrasound technology as a noninvasive method for maturation monitoring, we compared ultrasound observations and measurements in female Atlantic salmon (Salmo salar) during the last year before ovulation ... -
Ultrasound as a noninvasive tool for monitoring reproductive physiology in male Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2019)We examined the potential for ultrasound as a noninvasive tool for maturation monitoring in Atlantic salmon (Salmo salar) males. Ultrasound examination and measurements were compared to common practices for maturation ... -
Ultrastructures and cellular content of Phaeodactylum tricornutum studied by microscopy and flow cytometry
(Master thesis, 2023)Kiselalger er eukaryote fotosyntetiske mikroorganismer med økologisk betydning siden de er viktige primærprodusenter i den marine næringskjeden og fordi de bidrar til vesentlige geokjemiske sykluser. De har et unikt ... -
Uncovering the Impacts of Fencing in the Mara: An assessment of vegetation and bare soil using remote sensing and stakeholder participation
(Master thesis, 2019)Studier av arealbruk- og arealdekkeendringer benytter seg ofte av fjernregistrering via satelitter for overvåkning- og forvaltning av økosystemer, bevaringstiltak, samt kvantifisering av arealbruksendringer. Fjernregistrering ...
