Feeding ecology of a nocturnal invasive alien lizard species, Hemidactylus mabouia Moreau de Jonnès, 1818 (Gekkonidae), living in an outcrop rocky area in southeastern Brazil.

We studied in fieldwork, the feeding ecology of a Hemidactylus mabouia population from southeastern Brazil throughout one year in a region with marked climatic seasonality. A sampling of availability of arthropods in the environment was carried out, which evidenced that the availability of food resources influenced the composition of the diet of H. mabouia. There were no seasonal differences on diet composition, which may be due to the relatively constant availability on prey throughout the year. In general, this population can be classified as generalist and opportunistic regarding diet. There was a high food niche overlap among juveniles and adults, although juvenile lizards tend to eat higher number of prey (but in lower volume) when compared to adult lizards. The ability to exploit a wide array of prey in an efficient way, maintaining a positive energetic balance, may be a factor determining the efficiency of this exotic species to occupy invaded areas.
