Phylogenetic signal and comparison of uni- and multi-variate trait means between guilds. Plots report the variation of results from a sample of 100 alternative phylogenies (considering the uncertainty in divergence time estimation and local topology). Black dots indicate the results obtained from analyses using the consensus tree (as reported in Table 2). a) |$P$|-value of phylogenetic ANOVAs and MANOVAs; the red (dashed vertical) line indicates a significance level of 0.1. b) Phylogenetic signal. c and d) |$P$|-values of pairwise comparisons for traits |$\#$| 9 and |$\#$| 14; the red (dashed vertical) line indicates a significance level of 0.1 (color version online only).
