Abstract in Portuguese
O município de São Paulo possui 62.356 ha e apenas 16 % de áreas verdes. Desenvolvemos um estudo sobre a composição de espécies, história natural, diversidade e distribuição das serpentes no município. Ao longo de 44 meses, registramos 38 espécies de cinco famílias. Comparamos a diversidade de espécies de três unidades climáticas: áreas Norte, Central e Sul. Houve predominância de espécies terrícolas e anurófagas. Maior abundância foi observada na estação chuvosa, e deve estar relacionada à abundância de presas e/ou reprodução. A espécie dominante foi Oxyrhopus guibei, com 24 % de dominância, seguida por Sibynomorphus mikanii (21 %) e Bothrops jararaca (16 %). A área Central apresentou maior diversidade, com espécies típicas de diferentes fisionomias vegetais, como Cerrado, Serra da Mantiqueira e Serra do Mar. Historicamente, a região do município apresentava um mosaico de diferentes formações vegetais, que apesar de encontrarem-se fragmentadas atualmente, ainda abrigam conjuntamente alta diversidade de serpentes.

Abstract in English
The municipality of São Paulo has 62,356 ha, and only 16 % of green areas. We developed a study on species composition, natural history, diversity and distribution of snakes of the municipality. In 44 months, we recorded 38 species of snakes belonging to five families. We compared the species diversity of three climatic units: Northern, Central and Southern areas. The terrestrial and anurophagous species were predominant. Greater abundance was observed in the rainy season, and should be related to prey abundance and/or reproduction. The dominant species were Oxyrhopus guibei, with 24% of dominance, followed by Sibynomorphus mikanii (21 %), and Bothrops jararaca (16 %). The Central area showed larger diversity, with typical species from different physiognomic forms as Cerrado, Serra da Mantiqueira, and Serra do Mar. Historically, the municipality region showed a mosaic of different physiognomic forms that despite of being fragmented nowadays, still enclose together a high diversity of snakes.
