We investigated frugivory of Tropidurus torquatus in a rocky outcrop in the Pampa biome, southern Brazil over the course of one year. We quantified the number of seeds consumed, seed germination potential and the distance over which the seeds were dispersed, as observed through the analysis of faeces collected. Fruits of Chomelia obtusa, Ficus luschnathiana and two species of the genus Smilax were consumed, but only the former was effectively dispersed, since passage through the digestive tract did not affect its germination and the lizard deposited the seeds away from the mother plant. We discuss the ecological role of seed dispersal by T. torquatus between rocky outcrops.
