Abstract
A study of removal of fruits of the wild tomato, Solanum granulosoleprosum Dunal (N = 5 plants), by vertebrates was carried out in an urban environment of southern Brazil from January to May 1997 and February 1998. To verify diurnal and nocturnal removals, fruits were counted in several fruit bunches, being classified by size and color. Diurnal observations were made on plants to verify bird removal. A mist net was placed among the plants from the evening to 23:00 h to verify bat consumption. Live traps baited with S. granulosoleprosum fruits were placed on the ground among plants to verify terrestrial removers. On average it was found two ripe fruits available per bunch/day, but unripe, small, fruits were dominant (70%). Nocturnal mammals and birds-diurnal mammals partitioned fruits similarly. Bats removing fruits were Artibeus lituratus (Olfers, 1818), Pygoderma bilabiatum (Wagner, 1843) and Sturnira lilium (E. Geoffroy, 1810). Birds were Saltator similis Lafresnaye & d'Orbigny, 1837 and Thraupis sayaca (Linnaeus, 1766). Terrestrial mammals were a marsupial and three rodent species. Except for rodents, these vertebrates must be promoting the seed dispersal of S. granulosoleprosum seeds in disturbed mixed forests of southern Brazil.
