We could detect a strong relationship between lizards in open habitats and anthropic as well as a strong influence of the area to the richness and abundance of lizards, rather than habitat heterogeneity. The community was the most diverse State Park Cunhambebe. The lizards of island environments of the Sepetiba Bay showed a strong relationship between abundance and area, supporting the hypothesis of Ecological Release. The species Cycloramphus sp., Thoropa miliaris, Hylodes asper, H. phyllodes, Phasmahyla cruzi and Scinax trapicheiroi are those with lower values of tolerance of distance from this physiognomy and sometimes only occur in this environment. / Neste estudo foram investigadas as rela??es entre esp?cies de anf?bios anuros, lagartos, gradientes ambientais e insularidade. Nota-se uma forte rela??o dos lagartos com ambientes abertos e antr?picos, bem como uma forte influ?ncia da ?rea para a riqueza e abund?ncia dos lagartos, mais que a heterogeneidade de habitats. A comunidade mais diversa foi a do Parque Estadual do Cunhambebe. Os lagartos de ambientes insulares da Ba?a de Sepetiba demonstraram forte rela??o entre abund?ncia e ?rea, corroborando com a hip?tese de Libera??o ecol?gica. As esp?cies Cycloramphus sp., Thoropa miliaris, Hylodes asper, H. phyllodes, Phasmahyla cruzi e Scinax trapicheiroi s?o as que possuem menores valores de toler?ncia de dist?ncia da cachoeira e, algumas vezes, s? ocorrem neste ambiente
