      Falk-Andersson, Jannike; Foley, Naomi; Armstrong, Claire W.; van den Hove, Sybille; van Rensburg, Thomas; Tinch, Rob (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-17)
      This paper explores management challenges in relation to human impacts on cold water corals (CWC) in Norway. CWC are a slow growing organism about which there is uncertainty regarding distribution and values. We discuss area closures to protect this environmental public good against destructive fishing practices. Focus groups were combined with questionnaires to inform precautionary management ...
    • The demands they are a-changin' 

      Brækkan, Eivind Hestvik; Thyholdt, Sverre Braathen; Asche, Frank; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-15)
      Smooth operators such as time trends are often applied to deal with unidentified demand shifters. However, if unknown factors affect demand irregularly, a time trend fails to capture the variation. We present an index approach for estimating irregular demand shifts, decomposing total demand shifts into predicted and unexplained effects. This allows separating demand shifts caused by known factors ...
    • Demographic and economic disparities among Arctic regions 

      Schmidt, Jennifer Irene; Aanesen, Margrethe; Klokov, Konstantin; Kruschov, Sergei; Hausner, Vera Helene (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-20)
      We use demographic and economic indicators to analyze spatial differences and temporal trends across 18 regions surrounding the Arctic Ocean. Multifactor and cluster analysis were used on 10 indicators reflecting income, employment and demography from 1995 to 2008. The main difference is between regions with high population densities, low natural growth rate, and low unemployment (Russia, Norway ...

      Nielsen, Hanne Marie; Monsen, Brage Bråten; Ødegård, Jørgen; Bijma, Piter; Damsgård, Børge; Toften, Hilde; Olesen, Ingrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
    • Disentangling the influence of knowledge on attribute non-attendance 

      Sandorf, Erlend Dancke; Campbell, Danny; Hanley, Nick (Journal article; Tidsskriftartikkel, 2016-09-22)
      We seek to disentangle the effect of knowledge about an environmental good on respondents' propensity to ignore one or more attributes on the choice cards in a discrete choice experiment eliciting people's preferences for increased protection of cold-water corals in Norway. We hypothesize that a respondent's level of knowledge influences the degree to which she ignores attributes. Respondents ...
    • Diversifying selection drives parallel evolution of gill raker number and body size along the speciation continuum of European whitefish 

      Häkli, Katja; Østbye, Kjartan; Kahilainen, Kimmo Kalevi; Amundsen, Per-Arne; Præbel, Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-05)
      Adaptive radiation is the evolution of ecological and phenotypical diversity. It arises via ecological opportunity that promotes the exploration of underutilized or novel niches mediating specialization and reproductive isolation. The assumed precondition for rapid local adaptation is diversifying natural selection, but random genetic drift could also be a major driver of this process. We used 27 ...
    • DNA metabarcoding of littoral hardbottom communities: high diversity and database gaps revealed by two molecular markers 

      Wangensteen Fuentes, Owen Simon; Palacín, Creu; Guardiola, Magdalena; Turon, Xavier (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-04)
      Biodiversity assessment of marine hard-bottom communities is hindered by the high diversity and size-ranges of the organisms present. We developed a DNA metabarcoding protocol for biodiversity characterization of structurally complex natural marine hard-bottom communities. We used two molecular markers: the “Leray fragment” of mitochondrial <i>cytochrome c oxidase</i> (COI), for which a novel primer ...
    • DNA vaccines for fish: Review and perspectives on correlates of protection 

      Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-24)
      Recently in 2016, the European Medicines Agency (EMA) recommended granting a marketing authorization in the EU for “Clynav,” a DNA vaccine against salmon pancreas disease (salmonid alphavirus‐3). Generally, DNA vaccines induce both early and late immune responses in fish that may be protective against disease. Several transcriptomic approaches have been performed to map immunome profiles following ...
    • Do national resources have to be centrally managed? Vested interests and institutional reform in Norwegian fisheries governance 

      Jentoft, Svein; Mikalsen, Knut h (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Corporatism -with its privileged access, restricted participation and centralized structures - has a long history in Norwegian fisheries governance. Co-management – understood as a decentralized, bottom-up and more inclusive form of fisheries governance - has not been considered a relevant alternative.. Why does corporatism still prevail in a context where stakeholder status in fisheries governance ...
    • Do stocking densities affect the gut microbiota of gibel carp (Carassius auratus gibelio) cultured in ponds? 

      Ringø, Einar (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      The aim of the present study was to evaluate the intestinal microbial communities of gibel carp (Carassius auratus gibelio) cultivated in two beach ponds at different stocking densities. The two ponds were both ~3.33 hm2 in acreage and ~1.5 m in depth. The stocking densities included one intensive with 2 fish m–3 while the other treated as semi-intensive with 1 fish m–3. The gut microbiota (both ...
    • Domestic cats (Felis catus) in Denmark have increased significantly in size since the Viking Age 

      Bitz-Thorsen, Julie; Gotfredsen, Anne Birgitte (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-03)
      The earliest finds of domestic cat in Denmark date back to the Roman Iron Age (c. 1–375 AD). Initially, cats occurred sparsely and only from the Viking Age (c. 850–1050 AD) did they become more frequent in numbers, though primarily in urban contexts and in connection with fur production. In medieval times, cats became beasts of pest control in rural settlements, manorial estates as well as in the ...
    • Dynamics of bacterial community exposed to hydrocarbons and oleophilic fertilizer in high-Arctic intertidal beach 

      RØberg, stian; Østerhus, Jan ivar; Landfald, Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Exposure of pristine microbial environments to hydrocarbon contamination stimulates growth of the initially small fraction of indigenous hydrocarbon-degrading bacteria. Custom-made oleophilic fertilizers have been demonstrated to promote oil bioremediation by boosting this proliferation. In the present study, the temporal dynamics of the bacterial community structure and the individual influences ...
    • The ecological and economic value of cold-water coral ecosystems 

      Foley, Naomi; Armstrong, Claire W. (Journal article; Tidsskriftartikkel, 2010)
      Despite the growing scientific literature on cold-water corals (CWC) there appears to be no studies that address the economic values or economic management of the resource. This paper presents an overview of the goods and services of CWC and their associated biodiversity. Use and non-use values associated with CWC are presented, and the methods relevant for assessing their valuation are discussed. ...
    • Ecological linkages in a Caribbean estuary bay. 

      Andrade, Hector; Santos, Jorge; Ixquiac, MJ (Journal article; Tidsskriftartikkel, 2015-08-06)
      Central America and the western Caribbean form a center of freshwater and marine biodiversity that is now receiving attention in ecological and evolutionary studies. We conducted one integrated ecological study of Amatique Bay, Guatemala, a major estuary lagoon connected to the Mesoamerican Reef System, and provide novel information for management and conservation of similar systems across the ...
    • Economic Impacts of Global Warming : The Case of the Barents Sea Fisheries 

      Eide, Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2007)
      Regional analyses of possible physical and biological effects of global warming in the Barents Sea area have been carried out recently. Based on such studies possible economic impacts of global warming on the Barents Sea fisheries have been quantified, assuming different types of management regimes. The EconSimp2000 model, consisting of the ecosystem model AggMult and the fleet model EconMult have ...
