    • Resource competition drives an invasion-replacement event among shrew species on an island 

      Browett, Samuel S.; Synnott, Rebecca; O'Meara, Denise B.; Antwis, Rachael E.; Browett, Stephen S.; Bown, Kevin J.; Wangensteen, Owen S.; Dawson, Deborah A.; Searle, Jeremy B.; Yearsley, Jon M.; McDevitt, Allan D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-08)
      Invasive mammals are responsible for the majority of native species extinctions on islands. While most of these extinction events will be due to novel interactions between species (e.g. exotic predators and naive prey), it is more unusual to find incidences where a newly invasive species causes the decline/extinction of a native species on an island when they normally coexist elsewhere in their ...
    • Responding to global warming: New fisheries management measures in the Arctic 

      Jørgensen, Lis Lindal; Bakke, G.; Hoel, Alf Håkon (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-01)
      The northernmost commercial fisheries in the world take place in the northern Barents Sea up to around 80° N. This is an area where global warming is particularly intense and where large, previously ice-covered areas are now more accessible to fishing vessels. This raised questions whether existing conservation and management measures are adequate. In this paper, we discuss the process of developing ...
    • Results based management in fisheries: Delegating responsibility to resource users 

      Nielsen, Kåre Nolde; Holm, Petter; Aschan, Michaela (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-10-31)
      While the notion of results based management has been devoted recent attention in the context of reforming European fisheries management, it remains unclear what it entails. A conceptual model of results based management in fisheries is proposed as a way for public authorities to delegate specific management and documentation responsibilities to resource users. The model comprises three ...
    • Rethinking capitalist transformation of fisheries in South Africa and India 

      Menon, Ajit; Sowman, Merle; Bavinck, Jan Maarten (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
      The industrialization of fisheries and the growth of a capitalist sector within fisheries have received considerable scholarly attention. For the most part, scholars have emphasized how capitalism has led to privatization of the commons, forced small-scale resource users into wage labor, and marginalized the sector. This analysis does not, however, explain the continued presence of such a vibrant ...
