Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Under laboratory conditions, rates of oxygen consumption by hovering hummingbirds increase under reduced total pressure and under hypodense but normoxic conditions.

    “Under laboratory conditions, rates of oxygen consumption by hovering hummingbirds increases under reduced total pressure (Berger, 1974a,b) and under hypodense but normoxic conditions (Chai and Dudley, 1995).”

  • Manipulations of hovering flight in hummingbirds using hypodense helium mixtures under both normoxic and hypoxic conditions revealed that low-density air elicits a systematic increase in stroke amplitude but essentially unchanged wingbeat frequencies.

    “Manipulations of hovering flight in hummingbirds using hypodense helium mixtures under both normoxic and hypoxic conditions (Chai andDudley, 1995, 1996;Altshuler and Dudley, 2003) similarly revealed that low-density air elicits a systematic increase in stroke amplitude but essentially unchanged wingbeat frequencies.”

  • The interspecific increase in stroke amplitude of hovering hummingbirds at higher elevations, when coupled with the geometrical constraint on wing motions to amplitudes of approximately 180 on either side of the body, has important implications for aerodynamic and energetic reserves during flight.

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.
