Flower Constancy: Definition, Cause, and Measurement
Abstract
A pollinator that restricts its visits to one flower type, even when other rewarding types are accessible, can be said to exhibit flower constancy. This usage distinguishes constancy from fixed preference or labile preference for the most rewarding flower type; I discuss a quantitative constancy index that is insensitive to preference changes. Because a constant visitor avoids flowers with acceptable rewards, the behavior is inefficient unless there are constraints such as an inability to learn quickly or to remember simultaneously how to deal with many flower types. If such constraints are the basis for constancy, it should be most pronounced when flowers in a mixture differ strongly in morphology or color. I observed bees foraging in outdoor flower arrays and found that constancy always increased with increasing differences among flower types; similar results can be gleaned from one other study. The available experimental evidence thus suggests that constancy reflects behavioral constraints.

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.
