Figure 2


Fig. 2. The ants' first and second trips home after many food-bound runs. (A) Trajectories of ants after leaving the feeder (F). Trajectories ended after 6 min or before if the camera `lost' the ant. Trajectories are shown from when the ant has reached at least 10 cm from the feeder and end-points are marked by small black circles; large black circles indicate the landmarks. Trajectories from ants trained with the channel on the right hand side of the direct route to the food have been mirrored. (B,C,D) Circumferential positions of ants at 20 cm, 40 cm and 60 cm from the feeder. Grey lines represent the direct trajectory to the normal position of the cylinder. Arrow and range represent the mean heading and 95% confidence interval.
