Seed dispersal effectiveness of samango monkey (Cercopithecus albogularis schwarzi)
… potential compared to the mechanical and scarification of seeds via seed-swallowing, plants may trade quality for quantity, as the SDE of samango monkeys was greater for swallowed seeds. Time budget analysis showed that intergroup variability in feeding behaviour led to differences in the …
