Estimates of the mean value of feedback response r for each family pair (model 7), expressed as a deviation from the overall mean, as a function of the mean phylogenetic distance between the species pairs in each family pair. Estimates of mean feedback response between species in the same family are to the left of the dashed line, and estimates of mean feedback response between species in different families are to the right. Red circles identify family pairs where the mean response differed from zero as judged by 95% credible intervals. Labels above the red circles are abbreviated names for the family pairs: Ast‐Com, Asteraceae–Commelinaceae (n = 15); Ast‐Ona, Asteraceae–Onagraceae (n  =  2); Ast‐Ros, Asteraceae–Rosaceae (n  =  2); Car‐Poa, Caryophyllaceae–Poaceae (n  =  2); Com‐Fab, Commelinaceae–Fabaceae (n  =  2); Com‐Poa, Commelinaceae–Poaceae (n  =  19); Ona‐Poa, Onagraceae–Poaceae (n = 8); n, the number of feedback responses in each family pair.
