    • Differences in metabolic rate between two Atlantic cod (Gadus morhua) populations estimated with carbon isotopic composition in otoliths 

      Smolinski, Szymon; Denechaud, Come; von Leesen, Gotje; Geffen, Audrey J.; Grønkjær, Peter; Godiksen, Jane A.; Campana, Steven E. (Journal article; Peer reviewed, 2021)
      The isotopic composition of inorganic carbon in otoliths (δ13Coto) can be a useful tracer of metabolic rates and a method to study ecophysiology in wild fish. We evaluated environmental and physiological sources of δ13Coto ...

    • 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 ...
