Infection success of E. aconiatum cercariae in the second experiment. Proportion of encysted metacercariae in snails maintained at different temperature treatments for three or seven days before parasite exposure (20 cercariae per snail, 11 to 20 snails per treatment group) when the snails were exposed to parasite cercariae at 20°C. Data are shown as box plot with median, 25th (lower box) and 75th (upper box) quartiles; whiskers represent the values within the 1.5 interquartile range (outliers are shown as ●).
