FIGURE 4 in Specific damage recognised on land snail shells as a tool for studying predation intensity: differences related to habitat and predator types
FIGURE 4 Variation in the minimal rate of predation recorded in six samples collected in each of five habitat types. Different letters refer to significant differences (p <0.05) among habitat types, based on a generalised linear model. The central line of each box refers to the median value, box height to the interquartile range, whiskers to the non-outlier range (i.e., 1.5 times the interquartile range at each side), and small circles to outliers.
