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)
