Constant Connectance in Community Food Webs
Abstract
The constant connectance hypothesis states that among community food webs, trophic links increase approximately as the square of the number of functionally distinct or "trophic" species. This hypothesis is corroborated by the following analysis of 175 community food webs (2-93 trophic species), which shows that the exponent of the link-species relationship is approximately two. This scaling contradicts the widely accepted link-species scaling law, which asserts that links increase linearly with the number of species and that the link-species exponent is one. My results combined with related findings regarding food chain lengths indicate that large food webs have many more links and much longer food chains than previously suggested.

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.
