Table S4. Summary of the ANOVA analysis testing the
relationship between leaf vein density, habit (herb, shrub or tree) and
mycorrhizal state (AM, EM, AMNM and NM) on fine root diameter and
specific root length. F and p-values were calculated following an
ordinary linear model (OLS) for all species and separated into major
clades. Number in parentheses indicates the number of species included
in each model. Lambda values indicate the level of phylogenetic
independence of the data with values close to 1 indicating stronger
dependence. Monocots were not included due to the paucity of vein
density data for the group
