The phylogenetic structure of plant–pollinator interactions. a The prevailing pollinator group mapped, as a categorical variable, within the phylogeny of the plants. NA: ≥2 groups with the highest visitation rate. b The histogram of the null model of evolutionary transitions according to the algorithm ‘phylo.signal.disc’ for discrete traits. The arrow shows the number of observed transitions of the trait, which is significantly lower than the randomized median (**P = 0.008). c The two clades showing the lowest residuals (highest phylogenetic congruence) in the Procrustean cophylogenetic analysis.
