source leaves, stems, principal and lateral roots: biomass (dry weight), carbon allocation (13C excess) and nitrogen allocation (15N excess). Treatments comprise (a) control treatment, (b) EMF and mycorrhiza helper (beneficials), (c) root pathogen and mildew (pathogens), and with additional EMF (d), (e) root parasite, springtail and leaf herbivore (consumers), and with additional EMF (f). Springtail (Protaphorura armata) and Springtail-EMF data were obtained from Graf et al. (2019) and leaf herbivore (Lymantria dispar) and leaf herbivore-EMF data from Bacht et al. (2019). Each symbol represents the total distribution of biomass or resource allocation in an oak individual. Data points for each group are enclosed with a line, and red colour marks RF and blue colour marks SF. Based on a permutational multivariate analysis of variance, R-squared (R2) represents the proportion of the variance that's explained by growth stage, and asterisks indicate significant differences between the growth stages at the significance levels ***(P < 0.001); **(P < 0.01); *(P < 0.05); ns (not significant).
