  1. Sample sizes (tree/fruit) are in parenthesis. Proportions of mean seed numbers remaining in pellets relative to that in fig fruits were estimated. Species associated with a value with asterisks indicates a significantly greater value for fresh mature fruit than that of other species without asterisks under the same variable
  2. –, proportion was not estimated for F. microcapra because bats while feeding on F. microcarpa often culled multiple fruits in mouth, which resulted in pellets that might comprise remains of uncertain number of actual fig fruits
