Determination of trophic relationships within a high Arctic marine food web using δ13C and δ15N analysis
Open accessAbstract
We measured stable-carbon ( 1 3 C / 1 2 ~) and/or nitrogen (l5N/l4N) isotope ratios in 322 tissue samples (minus lipids) representing 43 species from primary producers through polar bears Ursus maritimus in the Barrow Strait-Lancaster Sound marine food web during July-August, 1988 to 1990.613C ranged from -21.6 f 0.3%0 for particulate organic matter (POM) to -15.0 f 0.7%0 for the predatory amphipod Stegocephalus inflatus.6 1 5 ~ was least enriched for POM (5.4 +.O.8%0), most enriched for polar bears (21.1 f 0.6%0), and showed a step-wise enrichment with trophic level of +3.8%0.We used this enrichment value to construct a simple isotopic food-web model to establish trophic relationships within thls marine ecosystem.This model confirms a food web consisting primanly of 5 trophic levels.b13C showed no discernible pattern of enrichment after the first 2 trophic levels, an effect that could not be attributed to differential lipid concentrations in food-web components.Although Arctic cod Boreogadus saida is a n important link between primary producers and higher trophic-level vertebrates during late summer, our isotopic model generally predicts closer links between lower trophic-level invertebrates and several species of seabirds and marine mammals than previously established.

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.
