    • 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 ...
    • Absenteeism in Norway - How does the North differ from the rest? A panel data study of the period from 2002 to 2011 

      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 ...
    • 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 ...
    • 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 ...
    • 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. ...
    • 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 ...
    • Adaptive temperature regulation in the little bird in winter: predictions from a stochastic dynamic programming model 

      Brodin, Anders; Nilsson, Jan‑Åke; Nord, Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-03)
      Several species of small birds are resident in boreal forests where environmental temperatures can be −20 to −30 °C, or even lower, in winter. As winter days are short, and food is scarce, winter survival is a challenge for small endothermic animals. A bird of this size will have to gain almost 10% of its lean body mass in fat every day to sustain overnight metabolism. Birds such as parids (titmice ...
    • Adjuvant activity of fish type I interferon shown in a virus DNA vaccination model 

      Chang, Chia Jung; Sun, Baojian; Robertsen, Børre (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-09)
      There is a need for more efficient vaccines to combat viral diseases of Atlantic salmon and other farmed fish. DNA vaccines are highly effective against salmonid rhabdoviruses, but have shown less effect against other viruses. In the present work we have studied if type I IFNs might be used as adjuvants in fish DNA vaccines. For this purpose we chose a DNA vaccine model based on the hemagglutin ...
    • Adjuvant combinations with the Toll-like receptor ligand CpG - Protective immune responses in Atlantic salmon 

      Thim, Hanna Leena (Doctoral thesis; Doktorgradsavhandling, 2016-12-01)
      Aquaculture is in need of improved viral vaccines to meet the demands of a growing sustainable industry. Fish viral vaccines are often based on less immunogenic antigen (Ag) formulations that require adjuvants to elicit sufficient protection. Toll-like receptor (TLR) agonists holds high immunostimulatory properties and are in mammals well explored vaccine adjuvants. The potential of synthetic ...
    • Adjuvants and immunostimulants in fish vaccines: Current knowledge and future perspectives. 

      Tafalla, C; Bøgwald, Jarl; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Vaccination is the most adequate method to control infectious diseases that threaten the aquaculture industry worldwide. Unfortunately, vaccines are usually not able to confer protection on their own; especially those vaccines based on recombinant antigens or inactivated pathogens. Therefore, the use of adjuvants or immunostimulants is often necessary to increase the vaccine efficacy. Traditional ...
