Table 2. Summary of the phylogenetic 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 a phylogenetic informed general linear model (PGLS) for seed plants and its major clades. Number in parentheses indicates the number of species included in each model. Lambda values indicate the level of phylogenetic dependence of the residuals in the linear model with 0 indicating complete independence and values close to 1 indicating stronger phylogenetic dependence. Monocots and Gymnosperms were not included due to the paucity of vein density data for these groups. waste
