Results of full statistical analyses describing numbers of total, small and rare snail species and individuals between non-invaded plots and plots invaded by plant species Fallopia sachalinensis, F. japonica, F.×bohemica and Impatiens glandulifera. Difference is a change in counts between non-invaded and invaded plots, with negative values indicating a decrease in snail numbers on invaded sites. Values ± standard errors are on transformed scales, numbers in parentheses are original counts. Significant differences between invaded and non-invaded plots for the individual plant species are in bold.Results of full statistical analyses describing numbers of total, small and rare snail species and individuals between non-invaded and invaded plots.
