  • Analysis of Bacterial Communities associated with the Tidal Zone Grass Puccinellia in Response to Diesel Spills 

    Freyer, Judith Marie (Master thesis; Mastergradsoppgave, 2024-11-15)
    Contamination from petroleum products and hydrocarbons is one of the major sources of pollution worldwide. The use of plants or microbes to reduce pollution is called bioremediation and is a cheap and environmentally friendly alternative to mechanical or chemical clean-up. A good understanding of native plants and microbes is required to implement bioremediation. In this study, the common and ...
  • Physiological impact of waterborne crude oil exposure to reproducing polar cod (Boreogadus saida) 

    Cremer, Ricarda (Master thesis; Mastergradsoppgave, 2024-11-15)
    Climate change-driven sea ice decline is increasing access to Arctic oil reserves and shipping routes, raising the risk of oil spills. Harsh polar conditions of extreme cold, darkness, and unpredictable weather will exacerbate these risks. The polar cod (Boreogadus saida), a key species in the Arctic ecosystem, may be particularly affected. With its spawning window in January and February, an oil ...
  • Studier av opptak av fiskepatogene bakterier i keratocytter fra laks og «Atlantic salmon kidney» (ASK) celler 

    Elde, Christiane Lovise (Master thesis; Mastergradsoppgave, 2023-12-01)
    Hudsår har blitt mer utbredt i norsk lakseoppdrett de senere år, hvor årsakene kan være flere og sammensatte. Vintersår regnes som en av de største helseutfordringene, der klassiske vintersår knyttes til bakterien Moritella viscosa. Hudsår hos oppdrettsfisk kan også skyldes sammensatt infeksjon med flere bakterier hvor bakteriene Vibrio anguillarum, Vibrio salmonicida og Aeromonas salmonicida, som ...

    Le, Thi Thanh Ngan; Armstrong, Claire W.; Brækkan, Eivind Hestvik; Eide, Arne Johannes (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-26)
    As recurrent disease outbreaks impart economic adversity across the global shrimp farming sector in general, and in Asia in particular, clarifying determinants of outbreak susceptibility carries significance for sustainability in economic growth and social and environmental prospects. This study employs logistic regression to assess the probability of disease occurrence in intensive white leg shrimp ...
  • The immune gene expression profile of sterile and fertile Atlantic salmon (Salmo salar L.) during smoltification and post transportation stress - A comparative overview 

    Sævareid, Katarina (Master thesis; Mastergradsoppgave, 2022-11-23)
    The escape of farmed salmon may result in unwanted interbreeding with wild salmon populations. The development of a sterile salmon can prevent the negative effect of unwanted genetic introgression as well as provide the industry with solutions to drawbacks associated with sexual maturation. A sterile fish will also improve the competitive strength of the 6 Norwegian breeding companies as the fish ...
  • Chemolithoautotrophic bacteria flourish at dark water–ice interfaces of an emerged Arctic cold seep 

    Delpech, Lisa-Marie; Tveit, Alexander Tøsdal; Hodson, Andrew; Hand, Kevin P.; Kalenitchenko, Dimitri Stanislas Desire (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-12)
    Below their ice shells, icy moons may offer a source of chemical energy that could support microbial life in the absence of light. In the Arctic, past and present glacial retreat leads to isostatic uplift of sediments through which cold and methane-saturated groundwater travels. This fluid reaches the surface and freezes as hill-shaped icings during winter, producing dark ice–water interfaces above ...
  • Genetics in the Ocean's Twilight Zone: Population Structure of the Glacier Lanternfish Across Its Distribution Range 

    Quintela, María; García-Seoane, Eva; Dahle, Geir; Klevjer, Thor A.; Melle, Webjørn Raunsgård; Lille-Langøy, Roger; Besnier, Francois; Tsagarakis, Konstantinos; Geoffroy, Maxime; Rodríguez-Ezpeleta, Naiara; Jacobsen, Eugenie; Côté, David; Knutar, Sofie; Unneland, Laila; Strand, Espen; Glover, Kevin Alan (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-06)
    The mesopelagic zone represents one of the few habitats that remains relatively untouched from anthropogenic activities. Among the many species inhabiting the north Atlantic mesopelagic zone, glacier lanternfish (Benthosema glaciale) is the most abundant and widely distributed. This species has been regarded as a potential target for a dedicated fishery despite the scarce knowledge of its population ...
  • Who skis where, when? – A method to enumerate backcountry usage 

    Boutera Toft, Håvard; Karlsen, Kristoffer; Landrø, Markus; Mannberg, Hanna Andrea; Hendrikx, Jordy; Hetland, Audun (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-22)
    Backcountry skiers, travelling in avalanche terrain, account for a large proportion of avalanche fatalities worldwide. Despite this, the exact count of the number of recreationists exposed to avalanches (also known as the background information), is poorly documented in most countries. Without detailed background information on temporal and spatial backcountry usage, making well-reasoned decisions ...

    Husson, Berengere; Bluhm, Bodil Annikki Ulla Barbro; Cyr, Frédéric; Danielson, Seth L.; Eriksen, Elena; Fossheim, Maria; Geoffroy, Maxime; Hopcroft, Russell R.; Ingvaldsen, Randi Brunvær; Jørgensen, Lis Lindal; Lovejoy, Connie; Meire, Lorenz; Mueter, Franz; Primicerio, Raul; Winding, Mie (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-24)
    Climate change is rapidly modifying biodiversity across the Arctic, driving a shift from Arctic to more boreal ecosystem characteristics. This phenomenon, known as borealization, is mainly described for certain functional groups along sub-Arctic inflow shelves (Barents and Chukchi Seas). In this review, we evaluate the spatial extent of such alterations across the Arctic, as well as their effects ...
  • The Core of the Matter—Importance of Identification Method and Biological Replication for Benthic Marine Monitoring 

    Jensen, Mads Reinholdt; Agersnap, Sune; Egelyng Sigsgaard, Eva; Ávila, Marcelo De Paula; Glenner, Henrik; Wisz, Mary S; Thomsen, Philip Francis (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-14)
    Benthic macrofauna are important and widely used biological indicators of marine ecosystems as they have limited mobility and therefore integrate the effects of local environmental stressors over time. Recently, environmental DNA (eDNA) analysis has provided a potentially more resource-efficient approach for benthic biomonitoring than traditional morphology-based methods. Several studies have ...
  • Which ecological factors influence the level of intraspecific diversity within post-glacial fishes? A case study using Coregonus and Salvelinus

    1. While it is likely that ecological context is important, the factors that facilitate and maintain variable levels of intraspecific diversity in Salmonidae fishes across environments remain unclear.<p> <p>2. Using a meta-analysis of sympatric ecotype assemblages from two salmonid genera—Salvelinus and Coregonus—we evaluated the importance of ecological factors determining the number of sympatric ...
  • Lyden av Skallelv er en snekker i arbeid 

    Olsen, Kjell Ole Kjærland (Chapter; Bokkapittel, 2024-11-04)
    Stadig færre er bosatt på det stedet de vokste opp. Likevel kan slike steder være viktige for folks identitet og deres integrering i ulike fellesskap. En slik tilknytning kan analyseres som en form for slekting, der individer gjennom relasjoner og praksiser vedlikeholder og knyttes til fellesskap som for eksempel det kvenske. Materielt sett tar slike prosesser ofte utgangspunkt i en allmenn forståelse ...
  • Reproductive biology of lumpfish (Cyclopterus lumpus): a key to successful selective breeding 

    Puvanendran, Velmurugu; Burgerhout, Erik; Hansen, Øyvind J; Tveiten, Helge; Kjørsvik, Elin; Mlingi, Frank Thomas; Tomkiewic, Jonna; Mommens, Maren; Hageskal, Rikard; Iversen, Nina (Research report; Forskningsrapport, 2022)
    A detailed description of lumpfish reproductive biology has been described in terms of gonadal development using histological analysis and physiology using sex steroid development. This knowledge of basic reproductive biology of lumpfish has adopted by our industry partners in their breeding activities in their facilities. Our results demonstrated that spawning of lumpfish can be shifted using ...
  • Essential omega-3 fatty acids are depleted in sea ice and pelagic algae of the Central Arctic Ocean 

    Schmidt, Katrin; Graeve, Martin; Hoppe, Clara J. M.; Torres-Valdes, Sinhué; Welteke, Nahid; Whitmore, Laura M.; Anhaus, Philipp; Atkinson, Angus; Belt, Simon T.; Brenneis, Tina; Campbell, Robert G.; Castellani, Giulia; Copeman, Louise A.; Flores, Hauke; Fong, Allison A.; Hildebrandt, Nicole; Kohlbach, Doreen; Nielsen, Jens M.; Parrish, Christopher C.; Rad-Menéndez, Cecilia; Rokitta, Sebastian D.; Tippenhauer, Sandra; Zhuang, Yanpei (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-19)
    Microalgae are the main source of the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), essential for the healthy development of most marine and terrestrial fauna including humans. Inverse correlations of algal EPA and DHA proportions (% of total fatty acids) with temperature have led to suggestions of a warming-induced decline in the global production of these biomolecules ...
  • On the origin of bird's nest fungi: Phylogenomic analyses of fungi in the Nidulariaceae (Agaricales, Basidiomycota) 

    Kraisitudomsook, Nattapol; Ahrendt, Steven; Riley, Robert; LaButti, Kurt; Lipzen, Anna; Daum, Chris; Barry, Kerrie; Grigoriev, Igor V.; Rämä, Teppo; Martin, Francis; Smith, Matthew E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-07)
    Nidulariaceae, also known as bird’s nest fungi, is an understudied group of mushroom-forming fungi. The common name is derived from their nest-like morphology. Bird’s nest fungi are ubiquitous wood decomposers or saprobes on dung. Recent studies showed that species in the Nidulariaceae form a monophyletic group with five sub-clades. However, phylogenetic relationships among genera and placement ...
  • Exploring the Microbial Chassis-Effect: Implications Towards Greater Biodesign 

    Chan, Dennis Tin Chat (Doctoral thesis; Doktorgradsavhandling, 2024-12-11)
    As an engineering field, the goal of synthetic biology is to design, build and implement technological solutions that advance human capability. To achieve this, synthetic biologists must be open to exploring new avenues of engineering strategies and move beyond tradition. The host-chassis has historically been an overlooked design variable in the field of synthetic biology. We show in this thesis ...
