• A century of fish growth in relation to climate change, population dynamics and exploitation 

      Denechaud, Come; Smolinski, Szymon; Geffen, Audrey J.; Godiksen, Jane Aanestad; Campana, Steven E. (Journal article; Peer reviewed, 2020)
      Marine ecosystems, particularly in high‐latitude regions such as the Arctic, have been significantly affected by human activities and contributions to climate change. Evaluating how fish populations responded to past changes ...
    • Century-long cod otolith biochronology reveals individual growth plasticity in response to temperature 

      Smolinski, Szymon; Deplanque-Lasserre, Julie; Hjörleifsson, Einar; Geffen, Audrey J.; Godiksen, Jane Aanestad; Campana, Steven E. (Journal article; Peer reviewed, 2020)
      Otolith biochronologies combine growth records from individual fish to produce long-term growth sequences, which can help to disentangle individual from population-level responses to environmental variability. This study ...
    • Early life growth is affecting timing of spawning in the semelparous Barents Sea capelin (Mallotus villosus) 

      Berg, Florian; Shirajee, Samina; Folkvord, Arild; Godiksen, Jane Aanestad; Skaret, Georg; Slotte, Aril (Journal article; Peer reviewed, 2021)
      Capelin (Mallotus villosus) is a forage fish and a key species in the Barents Sea (BS). The BS capelin are semelparous and hence only spawn once along the north coasts of Norway and Russia before they die. The age at ...
    • Effects of temperature on tissue-diet isotopic spacing of nitrogen and carbon in otolith organic matter 

      Godiksen, Jane Aanestad; Chung, Ming-Tsung; Folkvord, Arild; Grønkjær, Peter (Peer reviewed; Journal article, 2019)
      Reconstruction of the trophic position of a fish can be performed by analysing stable nitrogen and carbon isotopes in otolith protein. However, ambient temperature may affect the tissue–diet isotopic spacing of stable ...
    • Growth portfolios buffer climate-linked environmental change in marine systems 

      Campana, Steven E.; Smolinski, Szymon; Black, Bryan A.; Morrongiello, John R.; Alexandroff, Stella J.; Andersson, Carin; Bogstad, Bjarte; Butler, Paul G.; Denechaud, Côme; Frank, David C.; Geffen, Audrey J.; Godiksen, Jane Aanestad; Grønkjær, Peter; Hjörleifsson, Einar; Jónsdóttir, Ingibjörg G.; Meekan, Mark; Mette, Madelyn; Tanner, Susanne E.; van der Sleen, Peter; von Leesen, Gotje (Journal article; Peer reviewed, 2022)
      Large-scale, climate-induced synchrony in the productivity of fish populations is becoming more pronounced in the world's oceans. As synchrony increases, a population's “portfolio” of responses can be diminished, in turn ...
    • Ontogenetic movements of cod in Arctic fjords and the Barents Sea as revealed by otolith microchemistry 

      Andrade Rodriguez, Hector Antonio; van der Sleen, Peter; Black, Bryan A.; Godiksen, Jane Aanestad; Locke V, William L.; Carroll, Michael Leslie; Ambrose, William G. Jr.; Geffen, Audrey J. (Journal article; Peer reviewed, 2020-04-06)
      The distribution of Atlantic cod (Gadus morhua) in northern Norwegian waters is expanding eastward and northward in the Barents Sea and along western Svalbard. In the Arctic fjords of Svalbard, cod has become abundant, but ...
    • Otolith “spawning zones” across multiple Atlantic cod populations: Do they accurately record maturity and spawning? 

      Denechaud, Côme; Geffen, Audrey J.; Smolinski, Szymon; Godiksen, Jane Aanestad (Journal article; Peer reviewed, 2021)
      Specific changes identified in the otolith macrostructure of Northeast Arctic cod as “spawning zones” are presumed to represent spawning events, but recent experimental studies have challenged this relationship. Because ...
