Table 1.
Summary of methods used to assess seed dispersal effectiveness.
Fig 1.
Number of Platymitra macrocarpa trees producing ripe fruit over seven years of phenological monitoring.
A maximum of 3 trees (out of seven monitored trees) fruited in any year.
Fig 2.
Quantity of fruit eaten by different consumers of Platymitra macrocarpa.
The image of a partially consumed fruit shows the soft dry outer part eaten by terrestrial consumers, and the seeds covered by juicy soft pulp that is consumed by the arboreal consumers.
Fig 3.
Major consumers of Platymitra macrocarpa.
A. Pig-tailed macaque biting into a whole fruit; B. White-handed gibbon consuming fruit in the canopy (Photo by Kulpat Saralamba); C. Elephant placing a fruit in its mouth; D. Sambar consuming a whole fruit.
Fig 4.
Fate of Platymitra macrocarpa fruit and seeds present on the forest floor.
(A) whole fruit, (B) partly-eaten fruit, (C) seeds under source canopy and (D) seeds away from the source. Shown are the numbers of fruits or seeds that remained in-situ each month and, of those, how many were noted to be rotten or that germinated over the 6-mo sampling period. Sample sizes for each treatment differ and are shown by the May bar on the graphs.
Fig 5.
Seed dispersal effectiveness (SDE) landscape, showing the seven consumers of Platymitra macrocarpa.
The circles indicate the quantitative and qualitative components, and the isoclines show the seed dispersal effectiveness (quantity × quality) of the consumers. The error bars represent the SE values.
Fig 6.
The relationship between seed dispersal effectiveness (SDE) and body weight of the seven consumers of Platymitra macrocarpa.
The consumers are divided according to their diet group.
