The animal-plant relationships are one of the most influent ecological interactions that shape the forest dinamics. The seed dispersion is one of the most important representants of these interactions and represent a crucial step in the plants reproductive cicle. Mammals, mainly primates and ungulates of large body size consist the bulk of animal biomass in tropical forests, and as up to 90% of plant species have their seeds dispersed by zoochory and the mortality of non dispersed seeds is very high, is clear the importance of the animals in the maintenance and structuring of the tropical forests, speccially for large seeded species. These gruops are the main targets of hunters all over the world. The lack of these groups should have negative cascade effects on the plant communities, with consequences yet few known. The tapir and the woolly spider monkey are the largest terrestrial and of Brazil, respectively. They eat a high diversity and quantity of fruits and have large home ranges and daily movements, playing an important role in the forest dynamics mainly through frugivory and seed dispersal, despite This project have the objectives to describe and characterize the role of these two species on frugivory and seed dispersal in one of the most pristine remnants of Atlantic Forest of Brazil
