Number of snails of each type per Spartina stem at low tide in the (A) presence and (B) absence of a predator in a 12-week mesocosm experiment. The number of snails per Spartina stem was equivalently low across snail types and plant communities in the presence of a predator. In contrast, more J-snails climbed on Spartina in the Spartina-only treatment than in the mixed community when predators were absent. Letters indicate significant differences at P < 0.05 based on Tukey’s post hoc tests. Bars represent means ± 1SE.
