Rescaling the trophic structure of marine food webs
Open accessAbstract
Measures of trophic position ( TP ) are critical for understanding food web interactions and human‐mediated ecosystem disturbance. Nitrogen stable isotopes (δ 15 N) provide a powerful tool to estimate TP but are limited by a pragmatic assumption that isotope discrimination is constant (change in δ 15 N between predator and prey, Δ 15 N = 3.4‰), resulting in an additive framework that omits known Δ 15 N variation. Through meta‐analysis, we determine narrowing discrimination from an empirical linear relationship between experimental Δ 15 N and δ 15 N values of prey consumed. The resulting scaled Δ 15 N framework estimated reliable TP s of zooplanktivores to tertiary piscivores congruent with known feeding relationships that radically alters the conventional structure of marine food webs. Apex predator TP estimates were markedly higher than currently assumed by whole‐ecosystem models, indicating perceived food webs have been truncated and species‐interactions over simplified. The scaled Δ 15 N framework will greatly improve the accuracy of trophic estimates widely used in ecosystem‐based management.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
