Terrestrial mammals are good dispersers of the fruits and seeds of seasonal rainforest in the Gulf of Mexico. Their importance lies in the huge quantity of fruit and seeds they consume, and their daily and seasonal movement through natural and secondary vegetation and agricultural fields. Their importance is even more noteworthy in the face of increasing deforestation and forest fragmentation, which limits the dispersal of propagules across the landscape and affects, among other things, the potential for forest regeneration. To evaluate fruit and seed consumption and dispersal over 12 months, the droppings of rainforest mammals were analyzed for the rainforest and an abandoned pasture (8,400 m2 respectively) on the coast of central Veracruz, Mexico. In the rainforest 158 droppings were collected and 47 in the pasture from a total of eight mammal species, six of which are known dispersers. The droppings contained 150 seeds belonging to 36 species and 19 families. The deposition of different species and quantities of seeds in the forest and pasture indicates that mammals disperse more rainforest species to the pasture than vice versa.
