  • The effect of coloured LED light treatments on the biosynthesis of flavonoids in woodland strawberry (Fragaria vesca L.) originating from different latitudes 

    Omole, Florence Omowumi (Master thesis; Mastergradsoppgave, 2019-07-31)
    Flavonoids are a group of phenolic compounds produced in plants. They have many biological functions in plants and also beneficial bioactivities in human’s health. Light quality is one of the major environmental factors regulating the accumulation of flavonoids in plants. Understanding plants accumulation of secondary metabolites in response to light qualities is important in order to optimize plants ...
  • International law and Crimean secession from Ukraine (part 2) 

    Ørebech, Peter Th (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
    <p>Introduction. This is an article on whether Crimea’s declaration of independence is illegal or not. Is it contradictory to international law? My working hypothesis is that “people’s” right to selfdetermination and selfgovernment are part of its “residual rights”. Referendum confirms the authenticity of the popular will; declaring independence. The main topic is whether remedial secession is ...
  • Kritisk viktig, men samfunnsøkonomisk ulønnsomt … 

    Bardal, Kjersti Granås; Solvoll, Gisle; Mathisen, Terje Andreas; Østbye, Stein (Journal article; Tidsskriftartikkel, 2021-04-19)
    <p>Samferdselsprosjekter som oppleves som kritisk viktige lokalt og regionalt, vurderes ofte som samfunnsøkonomisk ulønnsomme. Med mange prosjekter som konkurrerer om begrensede offentlige midler, er det da svært viktig at beslutninger om hvilke prosjekter som skal prioriteres er velbegrunnede og gjennomtenkte. <p>Den samfunnsøkonomiske analysen skal – ved å synliggjøre tiltakenes samfunnsøkonomiske ...

    Dybwad, Christine; Assmy, Philipp; Olsen, Lasse Mork; Peeken, Ilka; Nikolopoulos, Anna; Krumpen, Thomas; Randelhoff, Achim; Tatarek, Agnieszka; Wiktor, Józef M.; Reigstad, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-21)
    Phytoplankton blooms in the Arctic Ocean's seasonal sea ice zone are expected to start earlier and occur further north with retreating and thinning sea ice cover. The current study is the first compilation of phytoplankton bloom development and fate in the seasonally variable sea ice zone north of Svalbard from winter to late summer, using short-term sediment trap deployments. Clear seasonal patterns ...
  • To denoise or to cluster, that is not the question: optimizing pipelines for COI metabarcoding and metaphylogeography 

    Antich, Adrià; Palacin, Creu; Wangensteen, Owen S.; Turon, Xavier (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-05)
    <i>Background</i> - The recent blooming of metabarcoding applications to biodiversity studies comes with some relevant methodological debates. One such issue concerns the treatment of reads by denoising or by clustering methods, which have been wrongly presented as alternatives. It has also been suggested that denoised sequence variants should replace clusters as the basic unit of metabarcoding ...

    Prentzell, Mirja Tamara; Rehbein, Ulrike; Sandoval, Marti Cadena; De Meulemeester, Ann-Sofie; Baumeister, Ralf; Brohée, Laura; Berdel, Bianca; Bockwoldt, Mathias; Carroll, Bernadette; Chowdhury, Suvagata Roy; von Deimling, Andreas; Demetriades, Constantinos; Figlia, Gianluca; de Arauj, Mariana Eca Guimaraes; Heberle, Alexander Martin; Heiland, Ines; Holzwarth, Birgit; Huber, Lukas A; Jaworski, Jacek; Kedra, Magdalena; Kern, Katharina; Kopach, Andrii; Korolchuk, Viktor I; van't Land-Kuper, Ineke; Macias, Matylda; Nellist, Mark; Palm, Wilhelm; Pusch, Stefan; Ramos Pittol, Jose Miguel; Reil, Michèle; Reintjes, Anja; Reuter, Friederike; Sampson, Julian R.; Scheldeman, Chloë; Siekierska, Aleksandra; Stefan, Eduard; Teleman, Aurelio A; Thomas, Laura E; Torres-Quesada, Omar; Trump, Saskia; West, Hannah D; de Witte, Peter; Woltering, Sandra; Yordanov, Teodor E; Zmorzynska, Justyna; Opitz, Christiane A.; Thedieck, Kathrin (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-25)
    Ras GTPase-activating protein-binding proteins 1 and 2 (G3BP1 and G3BP2, respectively) are widely recognized as core components of stress granules (SGs). We report that G3BPs reside at the cytoplasmic surface of lysosomes. They act in a non-redundant manner to anchor the tuberous sclerosis complex (TSC) protein complex to lysosomes and suppress activation of the metabolic master regulator mechanistic ...
  • Valuing High Seas Ecosystem Conservation 

    Bui, Bich Xuân; Armstrong, Claire W.; Ankamah-Yeboah, Isaac; Hynes, Stephen; Needham, Katherine (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-16)
    The high seas provide a variety of ecosystem services that benefit society. There have, however, been few attempts to quantify the human welfare impacts of changes to the delivery of these benefits. We assessed the values of several key ecosystem service benefits derived from protecting ecosystems in the high seas of the Flemish Cap through choice experiments conducted in Canada, Norway, and Scotland. ...
  • Lifelong divergence of growth patterns in Arctic charr life history strategies: implications for sustainable fisheries in a changing climate 

    Grenier, Gabrielle; Tallman, Ross (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-18)
    Arctic charr (<i>Salvelinus alpinus</i> Linnaeus, 1758) are phenotypically variable with multiple life history strategies including anadromous and freshwater resident individuals. The mechanism determining life history is believed to be set early in life. Anadromous individuals show greater seasonality in growth and feeding after the first seaward migration relative to resident conspecifics. We used ...
  • Optimization of a low flow sampler for improved assessment of gas and particle bound exposure to chlorinated paraffins 

    Al Saify, Insam; Cioni, Lara; van Mourik, Louise M.; Brandsma, Sicco H.; Warner, Nicholas Alexander (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-23)
    An optimized low volume sampler was developed to determine both gas- and particle bound concentrations of short and medium-chain chlorinated paraffins (S/MCCPs). Background contamination was limited by the sampler design, providing method quantification limits (MQLs) at least two orders of magnitude lower than other studies within the gas (MQL: 500 pg (ΣSCCPs), 1.86 ng (ΣMCCPs)) and particle (MQL: ...
  • Conspecific migration and environmental setting determine parasite infracommunities of non-migratory individual fish 

    Rochat, Eloïse; Brodersen, Jakob; Costa, Isabel Blasco (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-24)
    Parasite infracommunities tend to be stochastic in nature, although environmental characteristics such as the type of water source in streams and host traits can have an effect on the biotic assemblages and by extension the parasite fauna. We examined the effect of water source and the rate of adult fish migration on the metazoan parasite infracommunities of conspecific juvenile brown trout, Salmo ...
  • Intentions to Consume Sustainably Produced Fish: The Moderator Effects of Involvement and Environmental Awareness 

    Skallerud, Kåre; Armbrecht, John; Tuu, Ho Huy (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-18)
    The purpose of this study is to apply the conceptual framework of the theory of planned behavior (TPB) to explain the consumption of sustainable produced fish in Sweden. We seek to understand the moderating role of food product involvement and environmental awareness as extensions of traditional constructs such as attitudes, social norms, and perceived behavioral control. The data were derived from ...
  • Growth and Maturation of a Subarctic Fish Community Under a Changing Climate 

    Stangeland, Atle Johannes Hætta (Master thesis; Mastergradsoppgave, 2021-06-15)
    Increasing water temperatures from novel climate change may alter freshwater fish life history strategies, especially those of fish populations in northern latitudes. Fish species life history strategies are reflected by their environments and increasing water temperature may alter the most favorable strategies considering growth and reproductive patterns. In this study, life history traits of a ...
  • Evaluation and use of a monitoring method to estimate Atlantic salmon spawning run 

    Pedersen, Sonja Lydia Kimo (Master thesis; Mastergradsoppgave, 2021-06-16)
    ARIS sonar and Timespace video cameras were used to estimate spawning run and migration pattern of Atlantic salmon in Máskejohka, a tributary belonging to the River Tana. Máskejohka has not been monitored before and needs more detailed information about the stock size and its migration pattern, after several years with declining Atlantic salmon catch. Data for the first weeks of the migration period ...
  • Distribution, reproductive ecology, and colouration of the Arctic skate Amblyraja hyperborea (Collett, 1879) in the North Atlantic Ocean 

    López Climent, Rebeca (Master thesis; Mastergradsoppgave, 2021-06-14)
    <i>Amblyraja hyperborea</i> is the cartilaginous fish with the widest distribution across the Arctic seas and shelves and yet, large parts of its biology remain unknown. In a changing climate where the ice cover in the polar regions is retreating and fisheries are expanding northward, studying poorly known species is more important than ever. To provide a more exhaustive understanding of this species, ...
  • Monitoring anthropogenic activity in the Hardangervidda wild reindeer range. Possible applications of crowdsourced Strava-data in remote settings 

    Holtmoen, Vilde Grøthe (Master thesis; Mastergradsoppgave, 2021-05-31)
    Seen in light of the increasing interest of nature-based tourism and recreational outdoor activities in Norway the last decades (Haukeland, Grue & Veisten, 2010), spatiotemporal information on human activity in remote areas and knowledge about how this activity may affect wildlife and nature is a crucial part of a knowledge-based management (Gundersen et.al., 2011, p.14; Gundersen, Strand & Punsvik, ...
  • Can spruce forest stands be adapted to climate-driven natural disturbances? The consequential effects of two key disturbance agents and their management in spruce dominated stands under climate change – A review 

    Andersson, Carl-Michael Heimo (Master thesis; Mastergradsoppgave, 2021-05-20)
    The purpose of the thesis is to support the initial stage of the Climate Smart Forestry Norway (CSFN) undertaken by a consortium between NMBU, NIBIO, LUKE (Finland), and Wageningen University & Research, which is a five-year project aimed to assess how Norway’s forests are best managed in order to adapt to climate change. As part of the CSFN project a framework for quantifying probability and effects ...
  • Temporal changes of persistent organic pollutants in Arctic foxes (Vulpes lagopus) from Svalbard 

    Méndez Collí, Gabriel Alberto (Master thesis; Mastergradsoppgave, 2021-05-18)
    Recent evidence shows that temporal changes of persistent organic pollutants (POPs) in Arctic ecosystems are not only due to emission patterns and regulations; environment-related changes in prey availability and long-range transport may also influence concentrations of these compounds in tissues of Arctic predators. Arctic foxes (Vulpes lagopus) in Svalbard, Norway, scavenge and hunt opportunistically ...
  • Effect of simulated latitudinal variation in daylength conditions on oscillations of circadian gene expression in populations of woodland strawberry (Fragaria vesca L.) from Northern Norway and Italy 

    Faehn, Corine (Master thesis; Mastergradsoppgave, 2021-05-15)
    Almost all species on Earth possess circadian rhythms that align their physiological processes with suitable times of day and year based on predictable changes in the light cycle. While it is known that natural variations exist in photoperiodic responses regulated by the circadian clock, there are currently no studies assessing the effect of latitudinal variations in daylength on the properties of ...
