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
