Anuran Species Composition From Chaco and Cerrado Areas in Central Brazil

“…Newly named one of the top priority conservation areas by the Brazilian Ministry of the Environment, the municipality of Porto Murtinho is greatly important for biodiversity conservation (Brasil 2016). The municipality's severe vegetation loss (Harris et al 2006) in recent years deserves greater concern and action because of the wide diversity of anuran species (Rosset et al 2009, Souza et al 2010. The municipality of Porto Murtinho is the only place in Brazil where Odontophrynus lavillai (Rosset et al 2009) and L. asper occur, the latter being recorded as "near threatened" by the IUCN (2018) in Mato Grosso do Sul State.…”

“…The municipality's severe vegetation loss (Harris et al 2006) in recent years deserves greater concern and action because of the wide diversity of anuran species (Rosset et al 2009, Souza et al 2010.

Thus, the anuran composition and the great landscape complexity of the Chaco and Cerrado environments evidence the importance of increasing studies about the ecology of communities and natural history of species, such as those that make up the municipality of Porto Murtinho, since they are necessary and important for conservation of organisms and for sensitive regions with high levels of anthropogenic threats.…”

“…,Rosset et al (2009),Souza et al (2010Souza et al ( , 2017, Amaral et al (2012), Sugai et al (2012), Sugai et al (2014a) and Pansonato et al (2011) provided additional information about registers of anuran species. Considering the opinion of experts (see Acknowledgements), we removed four species from the species list of Souza et al (2017): Boana crepitans (Wied-Neuwied 1924), Scinax similis…”

The advertisement call and geographic distribution of Odontophrynus lavillai Cei, 1985 (Anura: Odontophrynidae)

“…Later, it was recorded from several localities of Argentina, Bolivia, Paraguay, and Brazil based on chromosome count, erythrocyte size, and morphological characters (see also new records in Figure 1B). Odontophrynus lavillai is associated to the Dry and Humid Chaco Ecoregions, and marginally to the Yungas Ecoregion (Rosset et al 2006;2009 and literature cited therein).…”

“…The specimens studied here come from three localities of Argentina and they are undoubtedly assigned to O. lavillai by the diploid number of chromosomes, the skin on dorsum heavily granular and glandular, and three transversal dark brown blotches on dorsum, lacking a light middorsal stripe ( Figure 1A; Barrio & Pistol de Rubel 1972;Cei 1985;Rosset et al 2009). Males were found calling within the water (semisubmerged) in temporary ponds after heavy rains.…”
