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.
