Experimental Wing Damage Affects Foraging Effort and Foraging Distance in Honeybees Apis mellifera

Figure 2

(a) Mean (±1 SE) lifespan of workers in the treatment groups. Bars that share the same letter did not significantly differ. (b) Hazard rate (probability of death per day) against bee age for Control (closed circles, solid line) and Light treatments (open circles, dashed line). The lines represent exponential fits of the data (0.0068 e ^0.1t, 0.0148 e ^0.0861t, respectively). Only two groups are shown for the sake of clarity and the curve for the Heavy group did not differ significantly from that for the Light group.
