Human disturbance increases trophic niche overlap in terrestrial carnivore communities
Open accessAbstract
Significance: Niche theory posits that species must limit overlap in the use of space, time, or resources to minimize competition. However, human disturbances are rapidly altering ecosystems with uncertain consequences for niche partitioning. Dietary niche partitioning is the primary way many species limit interspecific competition, and it is particularly important for carnivores because diet overlap can trigger interference competition and interspecific killing. We used stable isotope analyses to examine carnivore diets across the Great Lakes region in the United States and show that carnivores inhabiting disturbed ecosystems consume more human foods, leading to significant increases in both niche breadth and dietary niche overlap among competing species. These results suggest that carnivores in human-dominated landscapes experience significant interspecific competition and conflict due to the consumption of human food subsidies.

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.
