The lateral displacements (Fig. 3C-D) were followed by bimodal heading distributions (Rao's test, P ), but the cumulative distribution of headings after lateral displacements differs statistically from that obtained after upwards ( == 0-65; P < ) and downwards ( == ; P < ) releases. The number of snails which returned to their original cluster site differs between the various release sites (Fig. 4). Homing performance was significantly higher following downward rather than upward (x2 =; P<) or horizontal displacement (x2 = ; P ). up. B.
