Fig. 3. Comparison between the `Landmark at unit 14' and `No landmark' conditions
reveals the point at which bees were drawn towards the landmark (i.e. a beacon
effect). (A) Reproduction of first
-turn distributions. (B) Cumulative
frequencies were tested statistically, and found to be different at unit 11
(see text), meaning that bees were drawn to the landmark from this point
onwards.
