  • Migration in seabirds: seasonal structure in space and environment across species, populations and individuals 

    Merkel, Benjamin (Doctoral thesis; Doktorgradsavhandling, 2019-05-21)
    Identifying drivers of population trends in migratory species is difficult, as they can face many stressors while moving through different areas and environments during the annual cycle. Their population response to environmental change may in addition be affected by consistent differences in individual behaviour, which are widespread in free-living populations. An understanding of the structure of ...
  • Towards a framework to guide and facilitate interdisciplinary social-ecological system research in practice. 

    Weber, Charlotte Teresa (Doctoral thesis; Doktorgradsavhandling, 2019-06-27)
    Social-ecological systems (SES) consist of a social and an ecological system that are linked through a complex interplay of social and ecological processes. SES can be studied through SES research, which has become increasingly important because it is thought that it can potentially address and solve many societal challenges, such as climate change, resource scarcity, and habitat degradation. SES ...
  • Ecophysiological Responses of Sea Ice Algae and Phytoplankton to a Changing Arctic 

    Kvernvik, Ane Cecilie (Doctoral thesis; Doktorgradsavhandling, 2019-03-29)
    The ice-covered seas of the Arctic have two major types of primary producers; phytoplankton growing in open waters and sea ice algae growing within and on the underside of the sea ice. This thesis investigates the controlling role of light availability on Arctic pelagic and sympagic (i.e. ice-associated) algae, and how light-induced responses are modulated by NO3 and pCO2 levels. A combination of ...
  • Implementation of ecosystem-based ocean management 

    Sander, Gunnar (Doctoral thesis; Doktorgradsavhandling, 2019-03-29)
    Ecosystem-based management (EBM) is a holistic approach for nature management that aims at achieving the good health and sustainable use of ecosystems. It is a complex and challenging concept: understanding ecosystems and human impacts upon them is complicated, there are demanding needs for collaboration and harmonisation of approaches and policies, and many conflicting interests must be balanced. ...
  • Catch quality and size selectivity in the Barents Sea bottom trawl fishery: effect of codend design and trawling practice 

    Brinkhof, Jesse Vallevik (Doctoral thesis; Doktorgradsavhandling, 2019-02-15)
    This study focused on two important issues on the Barents Sea bottom trawl fishery for Northeast Arctic cod (Gadus morhua L.); catch quality (i.e., the quality of the fish caught) and size selectivity. The high abundance of cod encountered in recent years in the Barents Sea, leading to subsequent large annual quotas, has led to increased interest in improving the quality of fish caught by trawls. ...
  • Embracing stakeholder engagement in sustainability-oriented innovation: Internal capabilities and dynamics of open innovation in the Norwegian minerals industry 

    Ghassim, Babak (Doctoral thesis; Doktorgradsavhandling, 2019-02-08)
    The transition towards a sustainable minerals industry will rely on pursuing sustainability-oriented innovation (SOI), requiring continuous innovations in extraction and production processes, product offerings and the way the industry deals with its social responsibilities. Considering the breadth of SOI, mineral firms have no choice but to engage with and seek knowledge from multiple key external ...
  • Understanding researchers’ intention and habit regarding publishing in open access journals 

    Moksness, Lars (Doctoral thesis; Doktorgradsavhandling, 2018-12-13)
    Scholarly publishing is the vessel for the dissemination of research articles. Contemporary scholarly publishing is achieved by two main models, open access (OA) and non-open access (non-OA). OA refers to articles that are available at no cost to the end-user; however, authors may incur a fee for accepted manuscripts. Non-OA articles are available at a cost, either via subscriptions or via individual ...
  • Stress responses influencing fillet quality of trawled Atlantic cod and haddock 

    Svalheim, Ragnhild Aven (Doctoral thesis; Doktorgradsavhandling, 2018-12-12)
    In this thesis, an experimental swim tunnel and cod-end was used as a model to investigate how stress during various stages of trawl capture affects fillet quality in terms of residual blood, time and hardness of post-mortem muscle stiffness and muscle colour of cod and haddock. In addition, the effect of stress on importance of timing of euthanasia was also addressed. The first stage of trawl ...
  • Governance and power in the planning of Scotland's seas 

    Smith, Glen (Doctoral thesis; Doktorgradsavhandling, 2018-11-21)
    Marine spatial planning (MSP) is rapidly becoming the dominant approach to managing human interactions with marine environments. As this happens we are making more attempts to understand how it operates and how it might be improved. This study focuses on the governance of complex marine environments through MSP in Scotland. It focuses specifically on transparency and participation in MSP, and the ...
  • Live-storage of wild mature cod (Gadus morhua L.) without feed supply. Effects on biological and quality properties 

    Ageeva, Tatiana N. (Doctoral thesis; Doktorgradsavhandling, 2018-09-28)
    The overall aim of this work was to obtain better understanding of how live-storage without feeding affects wild mature Atlantic cod (Gadus morhua L.) and quality of products obtained from such cod. Atlantic cod were live-stored without feeding for 82 days. First, gender-specific weight changes in both whole and gutted fish, as well as certain organs were studied (Paper I). Next, the effects of feed ...
  • Ocean migration of Atlantic salmon 

    Strøm, John Fredrik (Doctoral thesis; Doktorgradsavhandling, 2018-09-14)
    Atlantic salmon is experiencing population declines throughout most parts of its distribution range, with changes in the marine environment considered important contributors to the overall decline. Most of the current knowledge about Atlantic salmon’s ocean distribution originates from mark-recapture and genetic studies associated with high-sea fisheries and sampling surveys, and therefore, little ...
  • Anti-inflammatory, antioxidative and anti-atherogenic bioactivity in marine sources ascribed to nonlipid constituents 

    Walquist, Mari Johannessen (Doctoral thesis; Doktorgradsavhandling, 2018-08-31)
    Cardiovascular disease (CVD) has been, and continues to be, one of the main causes of global deaths. For decades, fish consumption has been acknowledged to reduce the risk of CVD, especially omega-3 fatty acids are known to have anti-inflammatory properties. Still, there are indications that beneficial effects are not limited to fatty acids alone. In this study, the bioactivity in marine sources ...
  • Feeding and fasting in Arctic charr (Salvelinus alpinus (Linnaeus, 1758)): Central regulation of food intake in a highly seasonal fish species 

    Striberny, Anja (Doctoral thesis; Doktorgradsavhandling, 2018-05-22)
    Central control mechanisms of food intake vary between different fish species. Few studies have investigated the role of central appetite regulators in fish species that show natural seasonal variations in food intake. Yet, seasonal fishes are particularly interesting because their potential seasonally sliding set-points in appetite and energy homeostasis may reveal new information about the ...
  • Niche construction across climate gradients: the case of Empetrum nigrum in tundra plant communities 

    Tevendale, Victoria González (Doctoral thesis; Doktorgradsavhandling, 2018-06-08)
    Here we studied at relevant spatial and temporal scales, how the evergreen dwarf shrub Empetrum nigrum, through its niche constructor ability, affects tundra plant communities along climatic gradients. Empetrum is a common dwarf shrub which is particularly abundant in many tundra ecosystems. As a niche constructor is has strong influence on many ecosystem processes and its direct effects can last ...
  • Local support for biodiversity conservation in community-based protected area governance 

    Engen, Sigrid (Doctoral thesis; Doktorgradsavhandling, 2018-06-13)
    Worldwide there have been many attempts to implement community-based conservation to gain a more inclusive protection of biological diversity. Reducing human pressures on ecosystems is necessary for favorable ecological outcomes of protected areas, but conservation initiatives that rely on strict enforcement without local support are vulnerable to rule-violations, public protests and a reduced ...
  • Indulging in Premium versus Luxury products: Seeking justification to avoid regrets 

    Lyons, Sarah Joy (Doctoral thesis; Doktorgradsavhandling, 2018-05-22)
    The demand for premium products is expanding across saturated markets, such as food and beverages. Premium products stand out on the store shelf because they signal higher quality and exclusivity with their fine product packaging, higher prices, and selective distribution. Despite the growing consumer demand for these products, and acknowledgments in the literature that the lines between luxury and ...
  • Exploring social influences on children’s food attitudes and consumption 

    Alm, Siril (Doctoral thesis; Doktorgradsavhandling, 2015-06-27)
    Purpose: In light of the increasing numbers of overweight children observed today who follow inadequate diets, this dissertation mainly explored how children are socialised as food consumers. An additional purpose was to explore the advantages of using participatory photo interviews while researching children’s attitudes and behavioural patterns with respect to two food contexts, namely, lunch in ...

  • Just Like Putting Scissors to a Market - Investigating Supply and Demand Relations of Farmed Atlantic Salmon 

    Thyholdt, Sverre Braathen (Doctoral thesis; Doktorgradsavhandling, 2015-06-17)
    Price and quantity numbers, which we are observing in a market place, occur because of an interaction between supply and demand. An understanding of what drives supply and demand is therefore important in order to understand the market in itself. This dissertation focuses on determining the impact of exogenous factors on salmon biomass growth and how producers respond to price changes. Furthermore, ...
  • Antibacterial and anti-biofilm activity of novel marine natural product mimics 

    Mishchenko, Ekaterina (Doctoral thesis; Doktorgradsavhandling, 2017-01-20)
    Infectious diseases represent an urgent public health problem globally. Particularly healthcare-associated infections are often complicated by antibiotic resistance and presence of recalcitrant microbial biofilms. On the hunt for effective antibiotics with novel mechanisms of action (MOA), researchers look into largely unexplored natural environments with high biodiversity like the oceans, rich in ...
