O girino de Chiasmocleis alagoanus Cruz, Caramaschi & Freire, 1999 (Anura: Microhylidae)

Abstract

Tadpoles of Chiasmocleis alagoanus were collected from a temporary pond in a remnant of Atlantic Forest, municipal district of Maceió, Alagoas, Brazil. The tadpole presents lentic and nektonic habit. Body triangular in lateral view and oval in dorsal view; snout truncate in lateral, dorsal and ventral view. Eyes lateral and nostrils absent. Spiracle medial with wide opening. Anal tube ventral and short, with central opening, without free margin. Oral opening terminal, with marginal papillae and jaw sheaths absent, with the superior semicircular labial flaps suspended on the extremities of the mouth. Tooth rows absent. Tail length representing 59.1% of total length. In preservative the body is brown light and the viscera is partially visible. Notes on the environment and comparison with other tadpoles of the genera are provided.

The herpetofauna of the Serra do Urubu mountain range: a key biodiversity area for conservation in the brazilian atlantic forest

“…It's an explosive breeder species, reproducing in ephemeral ponds inside the forest (Nascimento & Skuk, 2006). At the Serra do Urubu mountain range only one individual was recorded, despite previous attempts to find the species in the region (Santos & Carnaval, 2002; showing the rarity of this species in the region.…”

Phylogeny, Taxonomic Revision, and Character Evolution of the GeneraChiasmocleisandSyncope(Anura, Microhylidae) in Amazonia, with Descriptions of Three New Species

“…In the later case, the following sources were consulted: Nelson, 1975;Duellman and Menselson III, 1995;Krü gel and Richter, 1995;Cruz et al, 1997;Cruz et al, 1999;Nascimento and Skuk, 2006;Moravec and Kö hler, 2007;Funk and Cannatella, 2009 A compilation of data on natural history, both from the literature and novel data (based on field notes and photographs), is given at the end of the manuscript, as is a brief comment on conservation. For these final sections, information on all species is compiled together.…”

Longevity and survival curves of Rhinella icterica (Anura, Bufonidae) under laboratory conditions

“…Environmental shifts potentially affect species, especially in life cycle stages most susceptible to ambient changing conditions. In this sense, the use of larval characters is very common among herpetologists -both for the diagnosis of species and for determination of intra-and intergeneric systematic relationships (Carneiro et al, 2004;Nascimento and Skuk, 2006;Casal and Juncá, 2008;Vieira and Arzabe, 2008).…”
