  1. Negative = negative control, Sand = physical control; Copper = positive control.
  2. “Cross” corresponds to the number of snails that reached the post and “Stop” corresponds to the number of snails that did not reach the post. Asterisks indicate a significant difference between two types of treatment (α = 0.05; *P < 0.05; **P < 0.01; ***P < 0.001. N.S not significant).
