      Falk, Martin; Tveteraas, Sigbjørn Landazuri; Xie, Jinghua (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-13)
      The number of economics-related articles in the Scandinavian Journal of Hospitality and Tourism (SJHT) has recently increased considerably. Despite this increase, the research efforts of Nordic economists on tourism issues have lagged behind in an international comparison. The recent increase in the number of economics-related publications in SJHT is due to better access to microdata (individual and ...

    • Abscisic acid regulates anthocyanin biosynthesis and gene expression associated with cell wall modification in ripening bilberry (vaccinium myrtillus l.) fruits 

      Karppinen, Katja Hannele; Tegelberg, Pinja; Häggman, Hely; Jaakola, Laura (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-29)
      Ripening of non-climacteric bilberry (Vaccinium myrtillus L.) fruit is characterized by a high accumulation of health-beneficial anthocyanins. Plant hormone abscisic acid (ABA) and sucrose have been shown to be among the central signaling molecules coordinating non-climacteric fruit ripening and anthocyanin accumulation in some fruits such as strawberry. Our earlier studies have demonstrated an ...

      Nyrud, Thomas Christer (Master thesis; Mastergradsoppgave, 2014-05-30)
      A panel data study of sick leave behavior in the Norwegian population is conducted on a municipality level for the period from 2002 to 2011. Data on sickness insurance usage is fitted against a selection of variables describing different regional characteristics that have been linked with absenteeism in the earlier literature. A basic model for sick leave usage is constructed, and further divided ...
    • Absorptive capacity and energy efficiency in manufacturing firms – An empirical analysis in Norway 

      Solnørdal, Mette Talseth; Thyholdt, Sverre Braathen (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-02)
      Increased energy efficiency (EE) in manufacturing firms is important for confronting climate challenges. However, the information barrier is considered a major restriction on EE innovation. Building on the theory of absorptive capacity and the current EE literature, we argue that this barrier relates to firms' ability to assimilate and exploit information. Thus, this study's objective is to analyse ...

    • Acceptance of near-natural greenspace management relates to ecological and socio-cultural assigned values among European urbanites 

      Lampinen, Jussi; Tuomi, Maria; Bucharova, Anna; Cancellieri, Laura; Casado-Arzuaga, Izaskun; Deák, Balázs; Eriksson, Ove; Fernández de Manuel, Beatriz; Filibeck, Goffredo; Kowarik, Ingo; Pons, Xavier; Schröder, Roland; Sperandii, Marta Gaia; Valkó, Orsolya (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-31)
      Grasslands are widespread elements of urban greenspace providing recreational, psychological and aesthetic benefits to city residents. Two urban grassland types of contrasting management dominate urban greenspaces: frequently mown, species-poor short-cut lawns and less intensively managed, near-natural tall-grass meadows. The higher conservation value of tall-grass meadows makes management interventions ...
    • Access to fishing grounds and adaptive strategies. The case of Chorkor and Nungua Fishing Communities of Greater Accra, Ghana 

      Sobang, Nicholas Badidaamet (Master thesis; Mastergradsoppgave, 2014-05-15)
      Artisanal fisheries are increasingly been accepted as the panacea for exploiting marine resources in costal Ghana. However evidence mustered over the years indicate that the local fisher-folk who are engaged in small scale fisheries hardly get full participation in making decision governing these resources. The current study examine the factors that constrain fishers participation in decision making ...
    • Accumulated marine pollution and fishery dynamics 

      Bergland, Harald; Pedersen, Pål Andreas; Wyller, John Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-05)
      We analyze the possible impacts of pollution on a fishery by means of a dynamical systems theory approach. The proposed model presupposes that activities stimulating economic growth also cause higher emissions that remediate or accumulate in the oceans. The density of pollution is assumed to affect the fishery negatively by reducing biological growth potential and decreasing marginal willingness to ...
    • Activity of XTHs during host plant infection by the parasitic plant Cuscuta. 

      Sarfowaa, Adwoa (Master thesis; Mastergradsoppgave, 2019-05-15)
      Parasitic plants including Cuscuta develop specialized structures called haustoria during infection. These specialized organs give the parasite the capacity of host attachment, invasion, vasculature connection and material transfer between the host and the parasite. Successful invasion allows organic substances, nutrients and water to flow into the parasite through the host phloem and xylem cells. ...
    • Activity of xyloglucan endotransglucosylases/hydrolases suggests a role during host invasion by the parasitic plant Cuscuta reflexa 

      Olsen, Stian; Krause, Kirsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-27)
      The parasitic vines of the genus Cuscuta form haustoria that grow into other plants and connect with their vascular system, thus allowing the parasite to feed on its host. A major obstacle that meets the infection organ as it penetrates the host tissue is the rigid plant cell wall. In the present study, we examined the activity of xyloglucan endotransglucosylases/hydrolases (XTHs) during the ...
    • Activity patterns in mammals: Circadian dominance challenged 

      Hazlerigg, David; Tyler, Nicholas J. C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-15)
      The evidence that diel patterns of physiology and behaviour in mammals are governed by circadian ‘clocks’ is based almost entirely on studies of nocturnal rodents. The emergent circadian paradigm, however, neglects the roles of energy metabolism and alimentary function (feeding and digestion) as determinants of activity pattern. The temporal control of activity varies widely across taxa, and ungulates, ...
    • Acute and long-term effects from petroleum discharges on temperate and Arctic Calanus species 

      Jensen, Louise Kiel (Doctoral thesis; Doktorgradsavhandling, 2011-11-11)
      Summary Petroleum exploitation is emerging in the Arctic. In the Norwegian Arctic the southern Barents Sea is opened for development of oil and gas fields. This same area holds some of the world's largest and well managed commercial fish stocks such as Herring (Clupea harengus), Capelin (Mallotus villosus), Haddock (Melanogrammus aeglefinus), Atlantic Cod (Gadus morhua). For the interest of the ...
    • Adaptive flexibility in the feeding behaviour of brown trout: optimal prey size 

      Sanchez-Hernandez, Javier; Cobo, Fernando (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-18)
      Background Brown trout, Salmo trutta Linnaeus, 1758, is a species of significant conservation and socio-economic importance. A consequence of this importance is the enormous amount of literature that has been published on the species in the last few decades. In general terms, brown trout has been considered as a size-selective predator, even though it is able to feed on a wide range of prey sizes. ...

      Chiffard, Jules; Marciau, Coline; Yoccoz, Nigel; Mouillot, Florent; Duchateau, Stéphane; Nadeau, Iris; Fontanilles, Philippe; Besnard, Aurélien (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-27)
      <ol> <li>Sampling efficiency is crucial to overcome the data crisis in biodiversity and to understand what drives the distribution of rare species.</li <li>Adaptive niche‐based sampling (ANBS) is an iterative sampling strategy that relies on the predictions of species distribution models (SDMs). By predicting highly suitable areas to guide prospection, ANBS could improve the efficiency of sampling ...
    • Adaptive radiation of the European whitefish Coregonus lavaretus (L.) in the Pasvik watercourse: the genetic description of a new morph 

      Couton, Marjorie (Master thesis; Mastergradsoppgave, 2012-11-26)
      Sympatric occurring fish morphs in postglacial lakes usually exhibit differences in morphology and physiology driven by adaptations to differential trophic niches. The European whitefish (Coregonus lavaretus (L.)) is a highly variable fish species, with more than 200 intraspecific forms described in Europe. The morphs usually differ in their number of gill-rakers, therefore this trait has been ...
    • The adaptive significance of chromatophores in the Arctic under-ice amphipod Apherusa glacialis 

      Fuhrmann, Mona Maria; Nygård, Henrik Andreas; Krapp, Rupert; Berge, Jørgen; Werner, Iris (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Solar radiation is a crucial factor governing biological processes in polar habitats. Containing harmful ultraviolet radiation (UVR), it can pose a threat for organisms inhabiting surface waters of polar oceans. The present study investigated the physiological color change in the obligate sympagic amphipod Apherusa glacialis mediated by red-brown chromatophores, which cover the body and internal ...
