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

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