Fig. 3. Data from retention experiments. Distance estimates of ants released
following a delay of 0 h (N=27, N=40, for 6 m and 12 m,
respectively), 24 h (N=42, N=38), 48 h (N=36,
N=39), 96 h (N=42, N=46), and 192 h (N=43,
N=41), trained to an outbound distance of 6 m (top) and 12 m
(bottom). Individual first turns, medians, and quartiles are shown.
