Abstract

Herein we present data on species composition, habitat use, and calling seasons of anurans from the Restinga forest of the Estação Ecológica Juréia-Itatins, Southeastern Brazil. The study site was visited monthly (3 to 4 days) between February and December 1993, a total of 28 days of field work. Three previously selected puddles were searched for anurans between 6:00 and 10:30 PM, when the number of calling males of each species was estimated and the positions of their calling sites were recorded. Anuran fauna is composed by 20 species, the highest richness ever recorded in a Brazilian restinga habitat. According to IUCN criteria, eight of these species have populations declining mainly due to habitat loss. Eleven species showed calling males in the three pools monitored during the study period; most hylids showed some vertical segregation on the marginal vegetation used as calling sites. Scinax hayii and S. littoralis were considered continuous breeders, but the calling and breeding period of most species was associated to the rainy season. The high species richness recorded and the indication of declining populations for some species outside the area suggest the E.E. Juréia-Itatins has a high potential to preserve anuran fauna. (AU)
