Figure 1.

Frequency histograms of pollen dispersal distances determined by parentage analysis for all juveniles in terra firme (A) and occasionally inundated (B) forests. The average frequency of definite pollen donors was calculated for 50 m distance classes from the maternal trees (black bars) and plotted together with the frequency of adult trees within each distance class (white bars). Adult trees in each plot were used to calculate the frequency of potential pollen donors in each distance interval.
