    • Human impact on highly mobile cetaceans: the use of biotelemetry data to inform ocean management 

      Mul, Evert (Doctoral thesis; Doktorgradsavhandling, 2020-12-03)
      <p>The human presence in the worlds’ oceans is increasing, in response to the growing demand for marine resources. This expansion of human activities will increase pressure on marine ecosystems and demands a responsible ocean management, to ensure the sustainable use of marine resources. Highly mobile marine top predators, such as cetaceans (whales, dolphins and porpoises) are exposed to a multitude ...

    • Impact of the COVID-19 pandemic on human-nature relations in a remote nature-based tourism destination 

      Mul, Evert; Murguzur, Francisco Javier Ancin; Hausner, Vera Helene (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-29)
      Tourism and nature-based recreation has changed dramatically during the COVID-19 pandemic. Travel restrictions caused sharp declines in visitation numbers, particularly in remote areas, such as northern Norway. In addition, the pandemic may have altered human-nature relationships by changing visitor behaviour and preferences. We studied visitor numbers and behaviour in northern Norway, based on ...

    • Implications of tag positioning and performance on the analysis of cetacean movement 

      Mul, Evert; Blanchet, Marie-Anne; Biuw, Martin; Rikardsen, Audun H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-17)
      <p><i>Background - </i>Satellite-linked animal-borne tags enable the study of free-ranging marine mammals. These tags can only transmit data while their antenna is above the surface for a sufficient amount of time. Thus, the position of the tag on the animal’s body will likely influence the quality and the quantity of location estimates. We explored the effects of tag placement and tag performance ...

    • Killer whales are attracted to herring fishing vessels 

      Mul, Evert; Blanchet, Marie-Anne; McClintock, Brett; Grecian, James; Biuw, Martin; Rikardsen, Audun H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-15)
      Marine mammals and fisheries often target the same resources, which can lead to operational interactions. Potential consequences of operational interaction include entanglements and damaged or reduced catches but also enhanced foraging opportunities, which can attract marine mammals to fishing vessels. Responsible fisheries management therefore requires detailed knowledge of the impact of these ...

    • Round-trip migration and energy budget of a breeding female humpback whale in the Northeast Atlantic 

      Kettemer, Lisa Elena; Mul, Evert; Blanchet, Marie-Anne; Rikardsen, Audun; Biuw, Martin; Broms, Fredrik Björn (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-27)
      In the northern hemisphere, humpback whales (<i>Megaptera novaeangliae</i>) typically migrate between summer/autumn feeding grounds at high latitudes, and specific winter/spring breeding grounds at low latitudes. Northeast Atlantic (NEA) humpback whales for instance forage in the Barents Sea and breed either in the West Indies, or the Cape Verde Islands, undertaking the longest recorded mammalian ...
