Statistical analyses
As described below, statistical analyses were conducted to (i )
model the effects of three experimental treatments (i.e., warming,
pesticides, and distances to parent trees) on seedling mortality using
Cox proportional hazards (PH) model, and (ii ) quantify changes in
the relative abundances of plant-pathogenic and EcM fungi in response to
the experimental treatments using negative binomial generalized linear
mixed models (GLMMs).
