    • Isoscape Models of the Southern Ocean: Predicting Spatial and Temporal Variability in Carbon and Nitrogen Isotope Compositions of Particulate Organic Matter 

      St. John Glew, Katie; Espinasse, Boris; Hunt, Brian P. V.; Pakhomov, Evgeny A.; Bury, Sarah J.; Pinkerton, Matt; Nodder, Scott D.; Gutiérrez-Rodríguez, Andres; Safi, Karl; Brown, Julie C. S.; Graham, Laura; Dunbar, Robert; Mucciarone, David A.; Magozzi, Sarah; Somes, Chris; Trueman, Clive N. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-30)
      Polar marine ecosystems are particularly vulnerable to the effects of climate change. Warming temperatures, freshening seawater, and disruption to sea-ice formation potentially all have cascading effects on food webs. New approaches are needed to better understand spatiotemporal interactions among biogeochemical processes at the base of Southern Ocean food webs. In marine systems, isoscapes (models ...

    • 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. ...

    • Tracing basal resource use across sea-ice, pelagic, and benthic habitats in the early Arctic spring food web with essential amino acid carbon isotopes 

      Vane, Kim; Cobain, Matthew R. D.; Trueman, Clive N.; Vonnahme, Tobias R.; Rokitta, Sebastian; Polunin, Nicholas V. C.; Flores, Hauke (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-09)
      A rapidly warming Arctic Ocean and associated sea-ice decline is resulting in changing sea-ice protist communities, affecting productivity of under-ice, pelagic, and benthic fauna. Quantifying such effects is hampered by a lack of biomarkers suitable for tracing specific basal resources (primary producers and microorganisms) through food webs. We investigate the potential of δ<sup>13</sup>C values ...
