This was used to determine the potential for gibbons to disperse seeds throughout their home range.
In this study, we estimated dispersal distances and deposition sites of seeds swallowed by two gibbon groups, using gut transit times and daily ranging patterns.
Both groups visited all 0.25-ha quadrats within their home range over the study period, indicating that gibbons potentially disperse seeds throughout their home range.
All scats and gibbon feeding trees were mapped.
There are several aspects of gibbon behaviour that may influence seed deposition in both positive and negative ways.
Our aim was to determine how three aspects of gibbon behaviour (revisitation of fruiting plants, daily and monthly ranging behaviour) influenced the final location of dispersed seeds.
The location of sleeping trees, fruit trees fed on by the gibbons, collected scats, and the extent of home ranges were plotted on maps of the study site.
Minimum gut retention times were recorded for 13 seed species, for which the first recorded feeding bout was on the third day of gibbon follows.
