    • Discrete foraging niches promote ecological, phenotypic, and genetic divergence in sympatric whitefish (Coregonus lavaretus) 

      Siwertsson, Anna; Knudsen, Rune; Præbel, Kim; Adams, Colin Ean; Newton, Jason; Amundsen, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Natural populations often vary in their degree of ecological, morphological and genetic divergence. This variation can be arranged along an ecological speciation continuum of increasingly discrete variation, with high inter-individual variation at one end and well defined species in the other. In postglacial fishes, evolutionary divergence has commonly resulted in the co-occurrence of a pelagic and ...

    • Temporal dynamics in zooplankton δ13C and δ15N isoscapes for the North Atlantic Ocean: Decadal cycles, seasonality, and implications for predator ecology 

      Espinasse, Boris Dristan; Sturbois, Anthony; Basedow, Sünnje Linnéa; Hélaouët, Pierre; Johns, David G.; Newton, Jason; Trueman, Clive N. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-17)
      The limited amount of ecological data covering offshore parts of the ocean impedes our ability to understand and anticipate the impact of anthropogenic stressors on pelagic marine ecosystems. Isoscapes, i.e., spatial models of the distribution of stable isotope ratios, have been employed in the recent years to investigate spatio-temporal patterns in biogeochemical process and ecological responses. ...
