    • Changing fish distributions challenge the effective management of European fisheries. 

      Baudron, Alan; Brunel, Thomas; Blanchet, Marie-Anne; Hidalgo, Manuel; Chust, Guillem; Brown, Elliot; Kleisner, Kristin; Millar, Colin; MacKenzie, Brian; Nikolioudakis, Nikolaos; Fernandes, Jose A.; Fernandes, Paul G. (Journal article; Peer reviewed, 2020)
      Changes in fish distribution are being observed across the globe. In Europe's Common Fisheries Policy, the share of the catch of each fish stock is split among management areas using a fixed allocation key known as ‘Relative ...

    • Don't mind if I do: Arctic humpback whales respond to winter foraging opportunities before migration 

      Kettemer, Lisa Elena; Ramm, Theresia; Broms, Fredrik Björn; Biuw, Martin; Blanchet, Marie-Anne; Bourgeon, Sophie; Dubourg, Paul; Ellendersen, Anna C. J.; Horaud, Mathilde; Kershaw, Joanna; Miller, Patrick J. O.; Øien, Nils Inge; Pallin, Logan J.; Rikardsen, Audun H. (Peer reviewed; Journal article, 2023)
      Migration patterns are fundamentally linked to the spatio-temporal distributions of prey. How migrating animals can respond to changes in their prey's distribution and abundance remains largely unclear. During the last ...

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

      Mul, Evert; Blanchet, Marie-Anne; Biuw, Martin; Rikardsen, Audun H. (Journal article; Peer reviewed, 2019)
      Background 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 ...

    • Killer whales are attracted to herring fishing vessels 

      Mul, Evert; Blanchet, Marie-Anne; McClintock, Brett; Grecian, James; Biuw, Martin; Rikardsen, Audun H. (Peer reviewed; Journal article, 2020)
      ABSTRACT: 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 ...

    • Novel feeding interactions amplify the impact of species redistribution on an Arctic food web 

      Pecuchet, Laurene; Blanchet, Marie-Anne; Frainer, Andre barbosa; Husson, Bérengère; Jørgensen, Lis Lindal; Kortsch, Susanne; Primicerio, Raul (Peer reviewed; Journal article, 2020)
      Species are redistributing globally in response to climate warming, impacting ecosystem functions and services. In the Barents Sea, poleward expansion of boreal species and a decreased abundance of Arctic species are causing ...

    • Overexploitation, Recovery, and Warming of the Barents Sea Ecosystem During 1950–2013 

      Pedersen, Torstein; Mikkelsen, Nina; Lindstrøm, Ulf; Renaud, Paul Eric; Nascimento, Marcela C.; Blanchet, Marie-Anne; Ellingsen, Ingrid H.; Jørgensen, Lis L.; Blanchet, Hugues (Peer reviewed; Journal article, 2021)
      The Barents Sea (BS) is a high-latitude shelf ecosystem with important fisheries, high and historically variable harvesting pressure, and ongoing high variability in climatic conditions. To quantify carbon flow pathways ...

    • The role of marine mammals in the Barents Sea foodweb 

      Blanchet, Marie-Anne; Primicerio, Raul; Frainer, André; Kortsch, Susanne; Skern-Mauritzen, Mette; Dolgov, Andrey V.; Aschan, Michaela (Peer reviewed; Journal article, 2019)
      Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 ...

    • 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 (Others, 2022)
      In the northern hemisphere, humpback whales (Megaptera novaeangliae) typically migrate between summer/autumn feeding grounds at high latitudes, and specific winter/spring breeding grounds at low latitudes. Northeast Atlantic ...
