Results of model selection for the analyses of total defoliation by Dryocosmus kuriphilus on chestnut trees in forests with increasing tree species diversity.

All models include plot identity as random factor. Univariate and multivariate models are shown, including their number of estimable parameters (K) and their Akaike’s weights (wi). Models within 2 AICc units (Δi) of the model with the lowest AICc are in italics. Estimated parameter values and standard deviations are indicated for these models with Δi Null = Null model; Richness = tree species richness; Shannon’s diversity index = Shannon index of tree diversity; C. sativa proportion = proportion of Castanea sativa; Taxonomic diversity = Taxonomic diversity index; Oak galls = Mean percentage of oak leaves with presence of Cynipid galls; Tree apparency = Tree apparency index.Results of model selection for the analyses of total defoliation by Dryocosmus kuriphilus on chestnut trees in forests with increasing tree species diversity.
