Abstract

The Fabaceae family holds great ecological and economic importance. Some species contribute to increased nitrogen levels in the soil (association with mycorrhizae), benefiting the natural regeneration process. Other species have high therapeutic value, while another can be used for ornamentation and urbanization. This study reports the presence of seeds from a tree species in the Fabaceae family, Dimorphandra jorgei M.F.Silva, in the fecal sample of South American tapir, Tapirus terrestris (Linnaeus, 1758), in a remnant of the Atlantic Forest in Southeastern Brazil. The fecal sample was found on an unpaved road, between the forest edge and an area undergoing reforestation with native species. Our record corroborates that D. jorgei can be an important supplementary food item in the tapir’s diet in the region, with its consumption linked to dry periods. The fruits of D. jorgei are not morphologically attractive to vertebrate fauna in general, highlighting the importance of tapirs in the dispersal of this and other species with similar fruits. It is also emphasized that seed dispersal contributes to the maintenance and regeneration of vegetation, serving as an Ecosystem Service of Support.
