Description:

Objective:

The objective of this research project is to investigate the relative significance of dispersers on the initial phase of forest organization, the seed rain. The research addresses the following questions:

• To what degree do arboreal frugivores influence the species richness and abundance of the seed rain?

• Do arboreal frugivores differentially disperse the seeds of specific life forms?

• Do unrelated taxa (frugivorous birds, monkeys, and rodents) represent similar or distinct functional dispersal groups?

Approach:

Seed rain was sampled for 12 months in the Dja Reserve, Cameroon. Traps were erected below the canopies of 90 individuals from nine focal tree species; three dispersed by monkeys, three dispersed by large birds, and three dispersed by wind. All seeds, fruits, and fruit or seed pieces were collected from traps at 10-day intervals.
