Means (±SE) of the attributes of leaf litter chemistry (the concentrations of secondary compounds are relative, i.e. given as peak area g⁻¹ dry litter material) in the insecticide treated and control saplings and the statistical significance of the difference between the means (tested using a pairwise <i>t</i>-test).

* Inlcudes (+)-catechin, DHPPG, cinnamic acid derivatives, flavonol glycosides (myricetins, quercetins and kaempferols), flavonoid aglycones and salicylates. Means (±SE) of the attributes of leaf litter chemistry (the concentrations of secondary compounds are relative, i.e. given as peak area g−1 dry litter material) in the insecticide treated and control saplings and the statistical significance of the difference between the means (tested using a pairwise t-test).
