Abstract
To study the impact of seed dispersal by
the Formosan macaques in affecting the
spatial distribution and fates of seeds, we
followed two troops of macaques at Fushan
experimental forest and recorded their
feeding behavior and locations where they
defecate or spit out seeds. The microhabitat
of the deposited seeds and feces were
evaluated, and the densities of seeds spat out
or in the feces were examined and followed
for the fates of seeds. We also conducted
manipulation experiments by setting seeds in
forest versus in open area at different
distance away from parent trees, with
different densities and with or without the
cover of macaques’ fecal material and
compared the survival, removal, and
germination rates of these seeds, and the
growth of seedlings. Preliminary results
indicated that macaques of different sexes
and ages differed in their feeding rates and
the ratio of seeds either dropped at or away
from feeding trees. Approximately 38% of
seeds were spat at feeding trees, the majority
of the rest of seeds consumed by the
macaques were dropped at the resting sites of
macaques. Seeds dropped in the forest had
significantly higher germination rates than
those in open areas. However, no significant
difference was found in the germination rates
between seeds dropped under the same or
different tree species, or between single seed
or clumped seeds.
