    • Atlantic cod individual spatial behaviour and stable isotope associations in a no-take marine reserve 

      Monk, Christopher; Power, Michael; Freitas, Carla; Harrison, Philip M.; Heupel, Michelle; Kuparinen, Anna; Moland, Even; Simpfendorfer, Colin; Villegas-Ríos, David; Olsen, Esben Moland (Peer reviewed; Journal article, 2023)
      Foraging is a behavioural process and, therefore, individual behaviour and diet are theorized to covary. However, few comparisons of individual behaviour type and diet exist in the wild. We tested whether behaviour type ...

      Ferter, Keno; Hartmann, Klaas; Kleiven, Alf Ring; Moland, Even; Olsen, Esben Moland (Journal article; Peer reviewed, 2014-10-07)
      Studying the sublethal effects of catch-and-release (C&R) is challenging, as there are several potential sources of bias. For example, if behavioural alterations immediately after the release event are to be studied, ...

    • Cod at drift in the North Sea 

      Huserbråten, Mats Brockstedt Olsen; Moland, Even; Albretsen, Jon (Journal article; Peer reviewed, 2018)
      There has been a large-scale geographical re-distribution of the North Sea cod stock over the past century, and recent surveys indicate a north-eastern modal distribution. Here we assess the consequences of the contemporary ...

      Huserbråten, Mats Brockstedt Olsen; Moland, Even; Knutsen, Halvor; Olsen, Esben Moland; André, Carl; Stenseth, Nils Chr. (Journal article; Peer reviewed, 2013-09-06)
      To ensure that marine protected areas (MPAs) benefit conservation and fisheries, the effectiveness of MPA designs has to be evaluated in field studies. Using an interdisciplinary approach, we empirically assessed the design ...

    • Demographic responses to protection from harvesting in a long-lived marine species 

      Fernández-Chacón, Albert; Buttay, Lucie; Moland, Even; Knutsen, Halvor; Olsen, Esben Moland (Peer reviewed; Journal article, 2021)
      Marine protected areas (MPAs) are usually considered to have positive effects on the recovery of over-exploited populations. However, resolving the extent to which MPAs function according to their conservation goals requires ...

    • Depletion of coastal predatory fish sub-stocks coincided with the largest sea urchin grazing event observed in the NE Atlantic 

      Norderhaug, Kjell Magnus; Nedreaas, Kjell Harald; Huserbråten, Mats; Moland, Even (Peer reviewed; Journal article, 2020)
      In this contribution, we propose fishery driven predator release as the cause for the largest grazing event ever observed in the NE Atlantic. Based on the evolving appreciation of limits to population connectivity, published ...

    • Disentangling structural genomic and behavioral barriers in a sea of connectivity 

      Barth, Julia Maria Isis; Villegas-Ríos, David; Freitas, Carla; Moland, Even; Star, Bastiaan; André, Carl; Knutsen, Halvor; Bradbury, Ian; Dierking, Jan; Petereit, Christoph; Righton, David; Metcalfe, Julian; Jakobsen, Kjetill Sigurd; Olsen, Esben Moland; Jentoft, Sissel (Journal article; Peer reviewed, 2019)
      Genetic divergence among populations arises through natural selection or drift and is counteracted by connectivity and gene flow. In sympatric populations, isolating mechanisms are thus needed to limit the homogenizing ...
