Fig. 3. (A,D,G) Dance probability before (open bars) and after (hatched bars) the
foragers' food-unloading. (B,E,H) Dance strength, i.e. number of round
circuits, before (open bars) and after (hatched bars) the food-unloading.
(C,F,I) Maximum number of simultaneous food-receivers (grey open bars) and
total number of food-receivers (grey hatched bars) involved in the foragers'
food-unloading (see Materials and methods for details). Data correspond to
marked bees that foraged individually on the IF. Results are shown for the two
different reward conditions (Low: 3 µl min-1, High: 90 µl
min-1) offered at the GF throughout the three different
experimental series: A,B,C constant series (N1=15,
N2=17), D,E,F decreasing series (N=7), and G,H,I
increasing series (N=6). See Results for details on statistics.
Values are means ± s.e.m.; *P<0.05,
**P<0.01, ***P<0.001.
