LOEBMANN, Daniel  e  VIEIRA, João P.. Amphibians list from Lagoa do Peixe National Park, Rio Grande do Sul, Brazil. Rev. Bras. Zool. [online]. 2005, vol.22, n.2, pp.339-341. ISSN 0101-8175.  https://doi.org/10.1590/S0101-81752005000200006.

This paper reports the first taxonomic list of amphibians from Lagoa do Peixe National Park. During the years 2001 and 2002 we sampled using Pit Fall Traps, visual searching and identification through vocalization activity. The study covered three different habitats: a) plains and swamps; b) coastal dunes and c) open beach. We observed 13 species into three families (Bufonidae, Leptodactylidae and Hylidae). All species were found along all coastal environment of Rio Grande do Sul. The number of species was different for each environment, being greater in plains and swamps, where all species were found. On the coastal dunes we found seven species of amphibians, being Physalaemus biligonigerus (Cope, 1861) and Bufo arenarum Hensel, 1867 the most abundant. Bufo arenarum was the unique specie that was found in the beach. According to literature, this species seems to be the only anuran able to support this environment which has strong influence of salinity, using it for feeding.
