Luis Amador, Fernando Ayala-Varela, Andrea E. Nárvaez, Keyko Cruz, Omar Torres-Carvajal


We report the first record of the invasive Brown Anole, Anolis sagrei Duméril & Bibron, 1837, in South America based on nine specimens from Samborondón, Guayas province, Ecuador. We also present some information related to the current distribution in Ecuador, and its possible impacts on native lizard species.
