Spatial Stratification of Internally and Externally Non-Pollinating Fig Wasps and Their Effects on Pollinator and Seed Abundance in Ficus burkei

Table 1

Summary of the wasps found in the 28 Ficus burkei syconia dissected for the study. Each row represents the possible combinations of pollinating wasps, externally ovipositing parasitic NPFWs (Philotrypesis/Sycoscapter/Sycoryctes), and P. barbarus in a syconium (i.e. row one represents syconia that only contained E. stuckenbergi). All 28 syconia produced seeds. The mean numbers (±S.E.) of wasps when present, and seeds, are given in the five columns to the right, along with ANOVA test results. ^∗𝑃<0.05; ^∗∗𝑃<0.001. Tests presented as significant remain so after sequential Bonferroni correction for multiple, non-independent tests. Different letters indicate a significant difference between groups (Fisher’s LSD post hoc tests).
