| Abstract | Occidental region of Sao Paulo state shelters the largest continuous remnant of Mesophytic Semideciduous Forest (Atlantic domain). Most of this region is legally protected by the Morro do Diabo State Park (MDSP), considered insufficient known but with probable biological importance concerning amphibians and reptiles. The present study aimed to study the spatio-temporal patterns of anuran distribution at MDSP, as well as to verify how environmental heterogeneity of breeding ponds influences on richness and anuran species composition. In general, recorded species (either calling males or tadpoles) occurred differentially among the studied breeding habitats, which was mainly related to the water flow and hidroperiod of breeding habitats. Thus, lotic, lentic permanent/semipermanent, and lentic temporary breeding habitats presented different anuran species composition. Temporal distribution of individuals was restricted to the moist and hot months (with exception to one species that occurred during the dry and cold months), resulting in a high temporal overlap of calling males and tadpoles distribution. Groups of species distributed differentially through the hot and moist months, where typical species of beginning, middle, and end of the rainy season could be identified. A macro-spatial analysis of anuran distribution evidenced low similarity among different sampled phytophysiognomies. Actually, the low faunistic similarity is rather a consequence of the low efficiency of capture by pitfall traps with drift fences, resulting in low species richness in the phytophysiognomies studied. However, a high similarity on species composition was found only among the most preserved areas of MDSP, due to the presence of Rhinella ornata. This species was indicative of the most preserved area of the MDSP, while two other species from the Leiuperidae family (Eupemphix nattereri and Physalaemus cuvieri), which are considered generalists in terms of habitat occupation, were indicative of the forest in advanced regeneration stage. Three out of the five environmental descriptors of the |
