Abstract
The present study was conducted in a remnant of semi-deciduous forest, Mata São José (MSJ), and in its adjacent areas in the municipality of Rio Claro, state of São Paulo, Brazil. Information about anuran species richness and their spatial and temporal distribution were collected from August 2002 to July 2003. Most of the 24 registered species called and breed in open areas around the remnant. Only three species, Hypsiboas  lundii , Hypsiboas  prasinus , and Proceratophrys  boiei , used environments inside the fragment as reproductive sites and only Hypsiboas  prasinus  used also environments around the remnant. The majority of the species were found during the rainy season and the temporary environments were the most used for reproduction. The species composition of MSJ was compared with 10 other localities with the following vegetation composition: a preserved tropical rain forest, ecotone of tropical rain forest and semi-deciduous altered forest, preserved Cerrado, and disturbed areas (used as agriculture and pasture for cattle). The anuran composition of the MSJ and that from other semi-deciduous forest were more similar to the anuran composition of more perturbed areas and to the anuran composition of Cerrado then to the anuran composition of the rain forest habitats. There was no significant correlation between the distance of the areas and the similarity ratio of them. Proceratophrys  boiei  and Hypsiboas  lundii  appear to be the species more affected by fragmentation of the habitats in the state of São Paulo due to their reproductive ecology and dependence of forest habitats.
