Table 4 Best models classified according to an AICc-based selection (with the “dredge” R-function) to explain Melolontha hippocastani egg density. Chi2 and P values result from a type II ANOVA

From: Oviposition preference of the forest cockchafer (Melolontha hippocastani Fabr. 1801) at the stand scale depends on oak proportion, canopy openness and ground accessibility
