Figure 3


Fig. 3. Path-integration of ants in L-shaped channels. Orientation and distance travelled by ants from the 6 mx6 m condition (A–C), and 6 mx3 m condition (D–F). Orientation of (A) experimental ants (6 mx6 m: {theta}=319.52°, r=0.96, N=30) and (B) control ants (6 m: {theta}=356.82°, r=0.98, N=16) that travelled only the first leg. Orientation of (D) experimental ants (6 mx3 m: {theta}=343.71°, r=0.95, N=30) that travelled a two leg trajectory and (E) control ants (6 m: {theta}=2.0°, r=0.98, N=18) that travelled only the first leg. Home direction is shown by the arrowhead outside the semi-circle. The mean vector direction {theta} is indicated by the grey arrow. r is represented by the length of the arrow. Distance path-integrated (means ± s.e.m.) by ants from experimental and control groups of the 6 mx6 m (C) and 6 mx3 m (F) conditions are shown.
