Ashmole's halo: direct evidence for prey depletion by a seabird
Open accessAbstract
Fish population densities were measured at various d~stances from 2 large colonies of double-crested cormorants Phalacrocorax auritus to test the hypothesis that seabirds deplete prey close to their colonies.Fish densities were significantly lower in bays used by cormorants for feeding than in those outside their foraging range.Our findings provide direct evidence for prey depletion, and support Ashmole's (1963) hypothesis that seabird populations are limited by food supplies during the breeding season.

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.
