Acoustic repertory of Hypsiboas exastis (Caramaschi and Rodgrigues, 2003) (Amphibia, Hylidae).

Advertisement, territorial, and distress calls of Hypsiboas exastis, a species of the Hypsiboas faker group, are described for the first time. Acoustic records were obtained of one specimen found at the Municipality of Urucuca, state of Bahia, Brazilian eastern cost. We compared the advertisement calls of H. exastis with those of H. lundii and H. pardalis (the closest related species) and suggested a closer similarity with H. lundii.

A new species of Hypsiboas from the Atlantic forest of southeastern Brazil (Amphibia : Anura : Hylidae)

We describe a new species of Hypsiboas of the Hypsiboas pulchellus species group from highland streams of the Atlantic Forest of southeastern Brazil. Vocalizations, egg-mass, and tadpole are also described. We compared the new species with other species of the Hypsiboas pulchellus species group. The new species is most similar to Hypsiboas semiguttatus, its sister species, and Hypsiboas curupi, from which it differs in advertisement call and larval morphology. We provide information on natural history, phylogenetic relationships, embryos, geographic distribution, and conservation.

Comparative larval morphology of eight species of Hypsiboas Wagler (Amphibia, Anura, Hylidae) from Argentina and Uruguay, with a review of the larvae of this genus

Predation on spawn and adults of Chaunus dorbignyi (Dumeril & Bibron, 1841) (Amphibia, Anura) by leeches (Hirudinea) in southern Brazil.

Two species of leeches (Hirudinea) are reported as frequently associated with amphibians in Rio Grande do Sul state, southern Brazil. We observed the predation of eggs of the bufonid Chaunus dorbignyi; remarkably, the remaining eggs of this clutch did not complete their embryologic development, probably due to a negative effect caused by the leeches. We report on additional observations of leeches feeding on other anuran species.

Amphibia, Anura, coastal zone, State of Piaui, northeastern Brazil.

Amphibians are an important component of terrestrial and aquatic freshwater communities worldwide. Especially to the Northern coastal zone of Brazil, the knowledge about amphibian communities is very scarce. We have studied amphibian assemblages along the coastal strip zone of the state of Piaui for two years, covering a distance of ca. 70 km. It was possible to prepare a list of 21 anurans from 6 families (Microhylidae, Hylidae, Leptodactylidae, Cycloramphidae, Leiuperidae, and Bufonidae). All species are common and widely distributed in Brazilian territory, mainly on the Caatinga biome. The results are important to amplify the knowledge on the biodiversity found at the coastal zone of the state of Piaui.

Amphibia, Anura, Brachycephalidae, Ischnocnema verrucosa Reinhardt and Luetken, 1862: distribution extension to northeastern Brazil.

Herein I present a new geographical record of Ischnocnema verrucosa Reinhardt and Luetken, 1862 fro northeastern Brazil and briefly discuss the new record with a previous record of similar characteristics.

Arcovomer passarellii Carvalho, 1954 (Amphibia: Anura: Microhylidae): distribution extension in São Paulo state, Brazil and geographic distribution map.

The Passarelli's Frog, Arcovomer passarellii Carvalho, 1954, was registered for the first time in the city of Santos, on the seacoast of São Paulo state, extending 160 km to southwest of the distribution previously known for this species. Here we show a distribution map for an up-to-date map for A. passarelli.

Tolerance to high temperatures in tadpoles of Leptodactylus fuscus and Hyla fuscovaria in temporary ponds (Amphibia, Leptodactylidae, Hylidae)

In temporary ponds tadpoles of the frogs Leptodactylus fuscus and Hyla fuscovaria may be exposed to temperatures up to 40-44°C. Experimental exposure to high temperature revealed survivals after 30 min at 42°C for H. fuscovaria and at 44°C for L. fuscus. -from Authors

New species of Hylodes from the Atlantic forest of Brazil (Amphibia: Leptodactylidae)

A new species of leptodactylid frog is described from Eldorado, state of Sao Paulo, southeastern Brazil. The new species is a member of the Hylodes lateristrigatus group and is characterized by its large size, slightly rugose to rugose dorsal skin texture, robust body, and high number of notes per call. Descriptions of the advertisement call and information on natural history are provided.

New species of Eleutherodactylus (Amphibia: Leptodactylidae) from Guaraquecaba, Atlantic Forest of Brazil

A new species of the leptodactylid frog genus Eleutherodactylus is described from Guaraquecaba, State of Parana, southern Brazil. The new species is characterized by its large size, slightly rugose to rugose dorsal skin texture, robust body, and low number of pulses per call. Descriptions of the advertisement calls of the new species and of E. manezinho, a close related species, are provided, as well as information on natural history.
