Figure 1. Effect plot showing the relationship between Raup-Crick similarity values of foliar fungal endophyte communities on Euclea crispa and BC area as a proxy for age of the BCs. Light blue shading represents the 95% confidence interval for the fitted model. Only significant trends are shown.
Figure 2. a-f) Significant retained predictor variables for the GDM performed on the full dataset. Each panel (a-f) represents the fitted I-splines (partial regression fits) of each retained predictor variable associated with the compositional turnover in foliar fungal endophyte communities. The maximum height reached by each curve represents the total amount of compositional turnover explained by that variable, holding all other variables constant.
Figure 3. a-c) Significant retained predictor variables for the GDM performed on the endophyte communities within the host Euclea crispa. d & e) Significant retained predictor variables for the GDM performed on the endophyte communities within the host Canthium inerme. f) Significant retained predictor variable for the GDM performed on the endophyte communities with the host Searsia chirindensis. Each panel (a-f) represents the fitted I-splines (partial regression fits) of each retained predictor variable associated with the compositional turnover in foliar fungal endophyte communities. The maximum height reached by each curve represents the total amount of compositional turnover explained by that variable, holding all other variables constant.
Figure 4. Predictor effect plots for the best subset GLMM model for ASV richness of foliar fungi. a) ASV richness decreased with light intensity - the x-axis represents inverse light intensity measured as photosynthetic active radiation (PAR) outside a BC minus PAR inside the BC. b) Maximum temperatures experienced within the BCs had no effect on ASV richness in C. inerme and E. crispa, but decreased with maximum temperature in S. chirindensis. c) Height of the trees from which samples were taken had no effect on ASV richness in C. inerme and E. crispa, whereas ASV richness decreased with maximum temperature in S. chirindensis. Light blue shading represents the 95% confidence interval for the fitted model.
