Extended Data Fig. 3: Phylogenetic diagram of foliar S concentration.
From: Empirical support for the biogeochemical niche hypothesis in forest trees
Phylogenetic diagrams of the foliar S concentration (25 112 datapoints) along the phylogeny tree obtained by using function phylosig of the package phytools in R (Revell59) representing the value structure used to estimate phylogenetic signal in the different variables. The function contmap estimates the ancestral characters at internal nodes using maximum likelihood and assuming Brownian motion as a model for trait evolution (Felsenstein63), and then interpolates ancestral condition along the branches of the tree (Revell64).
