![]() ![]() We also compared the Itirapina snake assemblage with nine snake assemblages of Brazil, from Amazonia, Atlantic Forest, Cerrado, and other open habitats. ![]() We present data on size, general abundance, habitat and macrohabitat use, daily and seasonal activity, feeding, reproduction, and defense. We also collected additional data from museum specimens housed in scientific collections. We performed an extensive field sampling combining six sampling methods in Estação Ecológica de Itirapina and disturbed Cerrado areas in its surroundings (municipalities of Itirapina and Brotas), during 101 trips throughout 43 months, between September 1998 and March 2002, corresponding to 446 days of field sampling. ![]() Our purpose in this work was the study of natural history and composition of the Cerrado snakes of Itirapina region. The Itirapina region has one of the last well preserved remnants of open cerrado in São Paulo state. Virtually no detailed study on Cerrado snakes was carried out in this region. In southeastern Brazil, the remnant Cerrado areas have suffered intense destruction, and presently less than 2% of Cerrado natural vegetation remain in São Paulo state. The Cerrado is the second largest biome in Brazil, and was included among the 25 World's biodiversity hotspots. Neotropical snake assemblages present high species richness and complex structures. ![]()
