Table 1.
Characteristics of chestnut plots and trees sampled along the gradient of tree species richness.
Fig 1.
Relationship between total defoliation by Dryocosmus kuriphilus and tree species richness at the plot level.
Dots represent the mean percentage of total defoliation per plot. The solid line and the shaded area represent predictions from linear mixed models and corresponding confidence interval.
Table 2.
Results of model selection for the analyses of total defoliation by Dryocosmus kuriphilus on chestnut trees in forests with increasing tree species diversity.
Fig 2.
Relationship between total defoliation by Dryocosmus kuriphilus and chestnut tree apparency at the neighborhood level.
Dots represent the percentage of total tree defoliation. The solid line and shaded area represent predictions by linear mixed models and corresponding confidence intervals. Dots on the left hand side and right hand side represent chestnut trees that were on average shorter and taller than their neighbors, respectively.
