Fig S1. Distribution of fine root trait values as observed across different phylogenetic groups. Panels A), C) and E) represent root tissue density (RTD), specific root length (SRL) and diameter among growth habits respectively. Panels B), D) and F) represent the same traits across mycorrhizal affiliations. Circles represent mean values and the two whiskers the 10th and 90th percentiles. Statistical values represent an ANOVA test with the phylogenetic clade and the categorical classifications as the fixed factors.
