Fig. 3. The development of trajectories. Trajectories are shown grouped by run
number. Ants are only included if they survived to perform at least 10 routes.
The end of the channel and the food are at (0,0) and (50,50), respectively.
Low barriers that were used to constrain ants within the half of the arena
containing the feeder influenced the paths on initial runs. (A) Food-bound
trajectories of ants (N=14) that were carried back to the nest after
feeding without performing homeward trajectories. (B,C) The food-bound and
homeward trajectories, respectively, of ants that performed round trips
(N=12).
