Effect of the habitat conditions (moisture and nutrient availability), the plant size (no. of leaves) and the species traits on the proportion of damaged leaves.

Two different tests using the plant traits were performed. A) The traits were selected using a step-wise both directional procedure, and only variables included in the final model are shown. B) Traits were summarized using principal component analysis (Figure 2), and the positions of species on the first, second, third and fourth axes were used as independent variables.
