  • Are Hooded seals (Cystophora cristata) endowed with mechanisms for non-shivering thermogenesis within the skeletal muscle? 

    Chiu, Matthew (Master thesis; Mastergradsoppgave, 2022-06-15)
    Hooded seals (Cystophora cristata) are marine mammals and are characterised as an “Arctic seal” species due to their close association to the pack ice. Their relationship with the ice and water creates challenges in maintaining an internal body temperature of ~37°C. In homeothermic animals, like the hooded seal, shivering is used for thermogenesis, however this can rapidly fatigue skeletal muscle. ...
  • Diving and feeding of adult Atlantic salmon when migrating through the coastal zone in Norway 

    Hedger, Richard David; Kjellman, Mari; Thorstad, Eva Bonsak; Strøm, John Fredrik; Rikardsen, Audun H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-23)
    Atlantic salmon post-spawners from a population in northern Norway were tagged with data storage tags (N = 773), and the depth use and diving behaviour of recaptured individuals within the coastal zone were examined, both on their outward migration to sea (N = 44) and their return to the natal river after overwintering at sea (N = 34). In addition, the stomach contents of 909 returning adults caught ...

    Blix, Arnoldus S; Ness, john; Lian, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-04-01)
    Experiences from the management of a semi-domesticated herd of muskoxen, mostly on an island outside Tromsø (~70º N; 19º E), over a period of 40 years have been collected, and data on husbandry practices, reproduction, diseases and longevity are presented and discussed.
  • Ruteark eller regneark? Kognitive utfordringer ved å løse finansoppgaver på papir og PC 

    Bertheussen, Bernt Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-02-08)
    Innebygde finansfunksjoner kan utføre avanserte beregninger i et regneark. Ved å kopiere formler i stedet for å lage dem manuelt, kan en løsning dessuten utvikles raskt. I artikkelen spør vi om det er mindre faglig krevende å løse oppgaver i et regneark enn på papir (ruteark). Vi forsøker å svare på spørsmålet ved å analysere en finansoppgave med Blooms reviderte taksonomi (BRT) for det kognitive ...

    Long-term data are critically important to science, management, and policy formation. Here we describe a number of data collections from arctic Canada that monitor vertebrate population trends of freshwater and marine fish, marine birds, marine and terrestrial mammals. These time series data cover the last ca. 30 years and capture a period from the onset of global changes affecting the Arctic up to ...
  • Is Glacial Meltwater a Secondary Source of Legacy Contaminants to Arctic Coastal Food Webs? 

    Mcgovern, Maeve; Warner, Nicholas Alexander; Borgå, Katrine; Evenset, Anita; Carlsson, Pernilla Marianne; Skogsberg, Stina Linnea Emelie; Søreide, Janne; Ruus, Anders; Christensen, Guttorm; Poste, Amanda (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-26)
    Climate change-driven increases in air and sea temperatures are rapidly thawing the Arctic cryosphere with potential for remobilization and accumulation of legacy persistent organic pollutants (POPs) in adjacent coastal food webs. Here, we present concentrations of selected POPs in zooplankton (spatially and seasonally), as well as zoobenthos and sculpin (spatially) from Isfjorden, Svalbard. ...
  • Land-cover, climate and fjord morphology drive differences in organic matter and nutrient dynamics in two contrasting northern river-fjord systems 

    Schultze, Sabrina; Andersen, Tom; Hessen, Dag Olav; Ruus, Anders; Borgå, Katrine; Poste, Amanda (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-31)
    Climate and land-use changes are leading to impacts on individual ecosystems as well as shifts in transfer dynamics between interconnected systems. At the land-ocean interface, changes in riverine inputs of organic matter (OM) and nutrients have the potential to lead to shifts in coastal carbon and nutrient cycling with consequences for ecosystem structure and function. In this study, we assess OM ...

  • Towards some general ecological principles 

    Wikan, Arild (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-01-03)
    Discrete deterministic age-structured, stage-structured and difference delay equation population models are analysed and compared with respect to stability and nonstationary behaviour. All three models show that species with iteroparous life histories tend to be more stable than species with semelparous life histories which allow us to conclude that this must be a fairly general ecological ...
  • Merging indigenous and scientific knowledge links climate with the growth of a large migratory caribou population 

    Gagnon, Catherine A.; Hamel, Sandra; Russell, Don E.; Powell, Todd; Andre, James; Svoboda, Michael Y.; Berteaux, Dominique (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-08)
    1. Climate change in the Arctic is two to three times faster than anywhere else in the world. It is therefore crucial to understand the effects of weather on keystone arctic species, particularly those such as caribou (Rangifer tarandus) that sustain northern communities. Bridging long-term scientific and indigenous knowledge offers a promising path to achieve this goal, as both types of knowledge ...
  • Uncovering the secrets they keep – the role of parasites in food web ecology 

    Moore, Shannon Elizabeth (Master thesis; Mastergradsoppgave, 2022-06-01)
    Interactions involving parasites often account for large proportions of links within aquatic food webs, yet few studies integrate parasites into their food web analyses. This analysis compares three sets of highly resolved food webs that differ in taxa composition, space, and time for a subarctic lake system. Key topological food web metrics, including connectance, linkage density, and mean generality ...
  • Molecular study of digenean diversity in aquatic organisms in northern Norway, with a focus on the seasonality of Crepidostomum [Braun, 1900] 

    Slåteng, Sigurd (Master thesis; Mastergradsoppgave, 2022-06-07)
    This study aimed to elucidate cryptic trematode diversity across multiple life stages in aquatic organisms. I collected samples from first intermediate hosts (bivalves), second intermediate hosts (amphipods and insect nymphs), and definitive hosts (fish), and identified them by use of molecular methods. Phylograms based on molecular markers from 28S and COI genes were used to identify nine species ...
  • The structure of nasal conchae in Svalbard rock ptarmigan (Lagopus muta hyperborea) with comparisons to three other Galliform birds 

    Westvik, Marie Aas (Master thesis; Mastergradsoppgave, 2022-05-27)
    Birds are endothermic homeotherms that regulate internal metabolic heat production to keep a stable body core temperature. Lung ventilation, which is required to obtain oxygen for metabolism, is potentially a large source for heat and water loss. In a polar habitat with low year-round temperatures and scarcity of food in the winter, conservation of heat and water is crucial for survival of the ...
  • Validating the Tritiated Water Method in Adult Harp Seal 

    Sørli, Bernhard Jakob Salen (Master thesis; Mastergradsoppgave, 2022-05-16)
    As one of the top predators in the northeast Atlantic, and most numerous, the harp seal (Pagophilus groenlandicus), has a significant role in the higher trophic levels in the ecosystem. Their condition can be an indicator of changes in prey availability, competition with other species or even climate. It can also be a useful tool in predicting the pup production and breeding success. The ...
  • Dive behaviour and respiration rates of humpback whales (Megaptera Novaeangliae) during foraging off Northern Norway, with implications for metabolic rate estimates 

    Gunnufsen, Rikke (Master thesis; Mastergradsoppgave, 2022-05-16)
    Knowing the metabolic rate of marine mammals is often important as baseline knowledge of their biology and physiology, e.g., to allow ecosystem assessments and estimation of their resource needs and use, and prey requirements. However, our current knowledge of energetics of large cetaceans is limited compared to many smaller cetaceans. Determining the energy expenditure of large free-ranging whales ...
  • Marine growth of introduced pink salmon (Oncorhynchus gorbuscha) caught in northern and central Norway 

    Paulsen, Tora (Master thesis; Mastergradsoppgave, 2022-05-16)
    The introduction of pink salmon in the White Sea area during the second half of the 20th century has resulted in the establishment of a self-sustaining population of pink salmon in rivers draining to the Barents Sea and North Atlantic Ocean. The size and abundance of pink salmon is dependent on survival during the marine phase, where they acquire more than 95% of their body weight. Investigating ...
  • Exploring the potential of an online platform for citizen science-based ecological monitoring of plant- and wildlife on the high-Arctic Archipelago Svalbard 

    Bruholt, Linn (Master thesis; Mastergradsoppgave, 2022-05-16)
    Citizen science is increasingly used to include in ecological monitoring over the past three decades. Web-based applications or smart phones enable citizens to record observations or experiences at larger temporal and spatial scale and provide opportunities for a larger number of citizens to participate in mapping observations. Citizen science can also be used to record, or map observed and experienced ...
