Fig. 4From: Spatial patterns of insect herbivory within a forest landscape: the role of soil type and forest stratumEffect of coverage of shrubs and herbs (CSH) on herbivory in sapling stratum (HS). (a) CSH (± SE) in plots that the highest herbivory existed in the sapling stratum was significantly lower than that in plots which had the highest herbivory in the upper or lower stratum. Capital letters above bars indicate statistical differences between different kinds of plots. (b) Correlation between HS and CSH in loam areas (R2 = 0.198, F = 19.518, P < 0.001).
