      The vast developmental opportunities offered by the world’s coasts and oceans have attracted the attention of governments, private enterprises, philanthropic organizations, and international conservation organizations. High-profile dialogue and policy decisions on the future of the ocean are informed largely by economic and ecological research. Key insights from the social sciences raise concerns ...
    • 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 ...
    • Valuing blue carbon changes in the Arctic ocean 

      Armstrong, Claire W.; Foley, Naomi; Slagstad, Dag; Chierici, Melissa; Ellingsen, Ingrid H.; Reigstad, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-25)
      The ocean capacity to store carbon is crucial, and currently absorbs about 25% CO<sub>2</sub> supply to the atmosphere. The ability to store carbon has an economic value, but such estimates are not common for ocean environments, and not yet estimated for the Arctic Ocean. With the severe climatic changes in the Arctic Ocean, impacting sea ice and potentially the vertical carbon transport mechanisms, ...

      Rozenfeld, Christoffer; García-Carpintero, Victor; Pérez, Luz; Gallego, Victor; Herranz-Jusdado, Juan Germán; Tveiten, Helge; Johnsen, Helge K.; Fontaine, Romain David; Weltzien, Finn-Arne; Cañizares, Joaquín; Asturiano, Juan F.; Penaranda, David Sanchez (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-22)
      <i>Background</i>: The impossibility of closing the life cycle of the European eel (<i>Anguilla anguilla</i>) in captivity troubles the future of this critically endangered species. In addition, the European eel is a highly valued and demanded resource, thus the successful closing of its life cycle would have a substantial economic and ecological impact. With the aim of obtaining the highest ...
    • An interdisciplinary insight into the human dimension in fisheries models. A systematic literature review in a European Union context 

      Weber, Charlotte Teresa; Borit, Melania; Aschan, Michaela (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-02)
      Fisheries are complex adaptive social-ecological systems (SES) that consist of interlinked human and ecosystems. They have mainly been studied by the natural sciences and focused on the ecosystem. However, rising concerns about sustainability and increasing complexity of societal challenges often require an understanding of fisheries in a SES context. For this purpose, the study of the human ...
    • Interdisciplinary optimism? Sentiment analysis of Twitter data 

      Weber, Charlotte Teresa; Syed, Shaheen (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-31)
      Interdisciplinary research has faced many challenges, including institutional, cultural and practical ones, while it has also been reported as a ‘career risk’ and even ‘career suicide’ for researchers pursuing such an education and approach. Yet, the propagation of challenges and risks can easily lead to a feeling of anxiety and disempowerment in researchers, which we think is counterproductive to ...

    • Trading off co-produced marine ecosystem services: Natural resource industries versus other use and non-use ecosystem service values 

      Aanesen, Margrethe; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-22)
      Ecosystem services (ESs) may be both non-market and market based. Both may provide important input to societal welfare. Using natural resources, or converting nature in the development of market based ES may impact the access to non-market or more conservationist ES, and vice versa. How does the general public trade-off between these two types of ES? We use two valuation studies in Northern Norway ...
    • Expert Assessment of Risks Posed by Climate Change and Anthropogenic Activities to Ecosystem Services in the Deep North Atlantic 

      Armstrong, Claire W.; Vondolia, Godwin Kofi; Foley, Naomi; Henry, Lea-Anne; Needham, Katherine; Ressurreição, Adriana (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-24)
      Sustainable development of the ocean is a central policy objective in Europe through the Blue Growth Strategy and globally through parties to the Convention on Biological Diversity. Achieving sustainable exploitation of deep sea resources is challenged due to the huge uncertainty around the many risks posed by human activities on these remote ecosystems and the goods and services they provide. We ...
    • Middlemen: good for resources and fishermen? 

      Pham, Thi Thanh Thuy; Flaaten, Ola; Skonhoft, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-16)
      This paper studies the role of middlemen in open-access fisheries and how the organization of the supply chains affects resource exploitation and the level and distribution of economic rent. Imperfect competition among middlemen can help ensure that fish stocks are not depleted, which is typically the case in open-access fisheries with competitive markets. Middlemen with market power can also induce ...
    • Resilience to exogenous shocks in environmental management regimes in the Arctic – lessons learned from survivors 

      Tiller, Rachel; Nyman, Elizabeth; Dankel, Dorothy Jane; Liu, Yajie (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-13)
      A changing climate will impact not only the environment but all levels of governance thereof, including the context of the close to 400 multilateral environmental management agreements signed since the year 2000. For the Ocean, researchers project that the increasing sea surface temperatures will facilitate large changes in the marine food web, including large shifts in distribution patterns of ...
    • Interbreeding between local and translocated populations of a cleaner fish in an experimental mesocosm predicts risk of disrupted local adaptation 

      Blanco Gonzalez, Enrique; Espeland, Sigurd Heiberg; Jentoft, Sissel; Hansen, Michael Møller; Robalo, Joana I.; Stenseth, Nils Christian; Jorde, Per Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-09)
      Translocation of organisms within or outside its native range carries the risk of modifying the community of the recipient ecosystems and induces gene flow between locally adapted populations or closely related species. In this study, we evaluated the genetic consequences of large‐scale translocation of cleaner wrasses that has become a common practice within the salmon aquaculture industry in ...
    • A participatory scenario method to explore the future of marine social‐ecological systems 

      Planque, Benjamin; Mullon, Christian; Arneberg, Per; Eide, Arne; Fromentin, Jean-Marc; Heymans, Johanna J; Hoel, Alf Håkon; Niiranen, Susa; Ottersen, Geir; Sandø, Anne Britt; Sommerkorn, Martin; Thébaud, Olivier; Thorvik, Thorbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-01)
      Anticipating future changes in marine social‐ecological systems (MSES) several decades into the future is essential in the context of accelerating global change. This is challenging in situations where actors do not share common understandings, practices, or visions about the future. We introduce a dedicated scenario method for the development of MSES scenarios in a participatory context. The objective ...
    • Can a large-mesh sieve panel replace or supplement the Nordmøre grid for bycatch mitigation in the northeast Atlantic deep-water shrimp fishery? 

      Jacques, Nadine; Herrmann, Bent; Larsen, Roger B.; Sistiaga, Manu Berrondo; Brčić, Jure; Gökçe, Gökhan; Brinkhof, Jesse (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-26)
      The Nordmøre grid is the principle bycatch mitigation device in many shrimp trawl fisheries. However, in several of these fisheries, bycatch is a problem because small sized fish can pass through the grid and enter the codend together with the targeted shrimp. One such fishery is the Northeast Atlantic deep-water shrimp (<i>Pandalus borealis</i>) fishery, where the use of a Nordmøre grid is mandatory. ...

      Liu, Yajie; Bailey, Jennifer L.; Davidsen, Jan Grimsrud (Journal article; Peer reviewed, 2019-04-24)
      This paper explores the ecosystem services provided by anadromous brown trout (often termed sea trout) populations in Norway. Sea trout is an important species in both freshwater and marine ecosystems and provides important demand-driven ecological provisioning and socio-cultural services. While the sea trout once provided an important provisioning service through a professional fishery and subsistence ...
    • Boreal marine fauna from the Barents sea disperse to Arctic Northeast Greenland 

      Andrews, Adam; Christiansen, Jørgen Schou; Bhat, Shripathi; Lynghammar, Arve; Westgaard, Jon-Ivar; Pampoulie, Christophe; Præbel, Kim (Journal article; Peer reviewed, 2019-04-09)
      As a result of ocean warming, the species composition of the Arctic seas has begun to shift in a boreal direction. one ecosystem prone to fauna shifts is the Northeast Greenland shelf. the dispersal route taken by boreal fauna to this area is, however, not known. This knowledge is essential to predict to what extent boreal biota will colonise Arctic habitats. Using population genetics, we show that ...
    • Industry-led fishing gear development: Can it facilitate the process? 

      Veiga-Malta, Tiago; Feekings, Jordan; Herrmann, Bent; Krag, Ludvig A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-16)
      In the reformed technical measures regulation, the European Union proposed a greater involvement of the fishing industry in the different managerial aspects of fisheries. However, having the industry as a main actor in gear development presents a new suite of challenges. The industry, while addressing an issue in the fishery, can modify several aspects of a fishing gear simultaneously, without ...
