    • The influence of prey distribution on marine top predator movements 

      Vogel, Emma (Doctoral thesis; Doktorgradsavhandling, 2023-12-08)
      Predation is an ecological process that relies on spatial and temporal co-occurrence of predators and their prey. In marine ecosystems, killer and humpback whales are considered sentinels of ecosystem health, given their critical roles as top predators in shaping marine food webs and their responsiveness to ecosystem changes. As they are seldom influenced by natural threats, they are model species ...

      Sirnes, Espen (Doctoral thesis; Doktorgradsavhandling, 2008-06-06)
      The literature on financial markets is vast and it is probably safe to say that all tools in the economists’ tool case have been applied to this field. In this dissertation I will present three papers that are very diverse in their approach to the subject of finance, but have an important common theme; asymmetric information and efficiency in financial markets.
    • Interactions between small rodents and their food plants in tundra habitats 

      Soininen, Eeva Marjatta (Doctoral thesis; Doktorgradsavhandling, 2012-10-19)
      Small rodents are key herbivores of arctic ecosystems, where their cyclic population dynamics have important implications for vegetation dynamics. The role of vegetation for shaping small rodent population dynamics remains, however, unclear. Evaluation of this interaction has been greatly hampered by the rather fragmentary knowledge of small rodents feeding ecology, which in turn is due to methodological ...

      Rijal, Dilli Prasad (Doctoral thesis; Doktorgradsavhandling, 2016-01-15)
      Exotic invasive giant hogweeds are infamous in Europe for their ecological and economic damage; however, the magnitude of their impact on plant diversity has not yet been fully explored. In addition, uncertainties in their source and route of introduction impede management interventions. In such cases, molecular markers may bridge gaps between invasion history and management by providing insight ...
    • The invasive red king crab (Paralithodes camtschaticus): Mortality, individual growth and dispersal in Norwegian waters 

      Windsland, Kristin (Doctoral thesis; Doktorgradsavhandling, 2014-10-01)
      To improve local economy, the red king crab (Paralithodes camtschaticus) was introduced to the Barents Sea by Soviet scientists in the 1960s. Adapting well to the new environment, the growing population gradually invaded new areas along the coast of northern Norway. The red king crab has become a valuable marine resource but as an introduced species, it is also a potential threat to the ecosystem. ...
