Table 1.

Reduced foraging efficiency after disturbance events. The foraging efficiency model describes the effect of treatment phase on the amount of zucchini consumed by colonies (in grams) per 45 min trial. The model estimates are relative to trial data from the pre-treatment phase, and the effect of time is relative to morning trials.
