Ant visual route navigation: How the fine details of behaviour promote successful route performance and convergence
Fig 2
Divergence pattern and means across strategies as lateral displacement increases.
(A-C) Absolute initial displacements vs mean test route displacements for a 20m learning route, across 75 environment seeds with 45 starting positions (up to ± 5.5m), evaluated with respect to the entire learning route for strategies involving (A) View Based Orientation - VBO, (B) Familiarity Based Modulation - FBM and (C) Cast and Surge - CS. (D-F) Similar analysis to the preceding figures, however now evaluated against the last 5% of the learning route (i.e. for destination reaching). (G-H) Mean Test Route Displacements averaged across all initial displacements, again with respect to the entire learning route and last 5% of the learning route respectively. Bars which share a letter indicate groupings which are not statistically significant, as according to a pairwise Games-Howell comparison with α = 0.05. In all cases error bars present standard error on the mean.
