ABSTRACT: We investigated the species composition and reproduction of an anuran community in a Restinga habitat in Ceará State of north-eastern Brazil. Twenty species of four families were observed and most of these reproduced in temporary ponds, whereas Boana raniceps and Scinax x-signatus were observed in a larger number of reproductive sites and micro-habitats. Vocalisation was seasonal, with the majority of the species showing reproductive activity only during the rainy season. Only three species also vocalised during the dry season. Increases in the number of vocalising species were associated with increases in rainfall and humidity but appeared to fall with rising temperatures. For most species, there was spatial overlap of vocalisation sites and strong temporal overlapping. The anuran community in the area was composed of a mix of species that can also be found in the Caatinga and Cerrado domains but not those of the Atlantic Forest.
