Figure 2 Seed set probability for conspecific and heterospecific treatments for self-compatible (SC) and self-incompatible (SI) recipient species (light blue: conspecific treatment; light green: heterospecific treatment). The estimated marginal means with their 95% confidence intervals for each group are plotted in red on top of the boxplots of the raw data. Overall, SC species have a higher seed set probability compared to SI species, independently of pollen treatment (SC/SI odds ratio= 0.02, SE= 0.04, p-Value=0.05)
Figure 3 Log-response ratio of seed number with heterospecific treatment (HP) on seed number with conspecific treatment (CP), within each pair (same pair ID) for non-zero counts in relationship with the phylogenetic distance between recipient and donor species for a) common recipient with common donor b) common recipient with rare donor c) rare recipient with rare donor d) rare recipients with common donors. The confidence intervals for the estimated trends are plotted around the estimated relationship (dark blue: common recipient; light blue: rare recipient). Log-response ratio values < 0 correspond HP seed number < CP seed number (HPI present); values equal to 0 correspond to HP seed number = CP seed number (no HPI); values > 0 correspond to HP seed number > CP seed number (HP improves seed set)
