摘      要：Background:Insect herbivory has profound impacts on ecosystem processes and *** many efforts have been made to recognize the main drivers of insect herbivory at different scales,the results are *** likely reason is that studies have insufficiently captured the spatially heterogeneous factors such as soil type and forest stratum within the stand that may significantly affect insect *** particular,there is a lack of studies that address the detailed spatial patterns of insect herbivory which are influenced by these ***:We measured the detailed spatial patterns of insect herbivory on cork oak(Quercus variabilis Bl.)in response to soil type(gravel soil and loam)and forest stratum(the upper,lower,and sapling stratum),and correlated these patterns with a set of influencing factors(litter coverage,coverage of shrubs and herbs,soil nutrients,soil moisture,and leaf traits)in a forest ***:Generally,insect herbivory was spatially heterogeneous within *** was significantly lower in gravel soil areas than in loam soil areas and the highest herbivory occurred in the lower ***,there were also 41 individual plots in which the highest herbivory occurred in the upper stratum and 29 plots in which the highest herbivory occurred in the sapling *** were significant differences in soil nutrient and water status between soil types,but no significant differences in leaf *** effects of forest stratum on leaf traits were also inconsistent with those on insect ***:Leaf traits may not be the main factors influencing insect herbivory in the *** type may have major effects on herbivory patterns by influencing litter coverage while higher coverage of shrubs and herbs may reduce herbivory in the sapling *** findings may advance our understanding of tree-herbivore interactions in real-world situations and have important implications for the sustainable managemen
