    • 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 ...

    • Contrasting management regimes indicative of mesopredator release in temperate coastal fish assemblages 

      Synnes, Ann-Elin; Olsen, Esben Moland; Jorde, Per Erik; Knutsen, Halvor; Moland, Even (Peer reviewed; Journal article, 2023)
      The absence of functional top predators has been proposed as a mechanism acting to shape fish assemblages in temperate marine ecosystems, with cascading effects on lower trophic levels. We explore this scenario by comparing ...

      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 ...

    • Disparate movement behavior and feeding ecology in sympatric ecotypes of Atlantic cod 

      Kristensen, Martin Lykke; Olsen, Esben Moland; Moland, Even; Knutsen, Halvor; Grønkjær, Peter; Koed, Anders; Källo, Kristi; Aarestrup, Kim (Peer reviewed; Journal article, 2021)
      Coexistence of ecotypes, genetically divergent population units, is a widespread phenomenon, potentially affecting ecosystem functioning and local food web stability. In coastal Skagerrak, Atlantic cod (Gadus morhua) occur ...
