“…Through expansion of reptiles inventories (Cruz et al 2014;Lucas et al 2016;Novelli et al 2012;São Pedro & Pires 2009;Silveira et al 2010), it has been found that there is high diversity of reptiles in the Cerrado biome (Brites & Baub 1988;Recoder & Nogueira 2007). These studies have even shown that the distribution of some species is increasing (Santos et al 2009;Novelli et al 2011).…”

The objective of the present study was to learn which species of Squamata reptiles occur in Protected Area São José, in Tiradentes, Minas Gerais, Brazil. Between November 2009 and December 2010 reptiles were captured. In total 157 specimens were recorded of 29 species, 16 snakes, 12 lizards and one amphisbaena. Among the snakes, Dipsadidae showed the greatest richness, with a total of nine species. The group of snakes had the highest number of species present in the community, but 79% of sampled specimens were lizards, Enyalius bilineatus being the most abundant species, with 21% of occurrence. The area with the highest richness was the Cerradão. The lower abundance was found in the Gallery Forest area (n=14), but it was the vegetation type with the highest equitability. Areas of Cerradão and Cerrado sensu strictu showed the most similarity. In these areas five species were recorded in common, Bothrops neuwiedi (n=3) being the only species of snake, and the two species of lizards most abundant in both environments were Enyalius bilineatus (n=32) and Ameivula ocellifera (n=19). Ophiodes striatus and Xenodon merremii were common to Cerradão and Dirty Field areas. There was no species recorded that were common to the environments of Cerrado and Dirty Field but two species not sympatric were found of the same genus, Tropidurus torquatus, which was found only in the Cerrado sensu strictu and Tropidurus itambere exclusively in Dirty Field. Since none of the rarefaction curves reached full asymptote, this highlights the need for further study due to the high probability of new species being recorded for the studied area.

“…However, these studies are still scarce, considering the size and the variety of habitats in the Cerrado. This shortage becomes greater with regard to transition areas between the Cerrado and other biomes (Bertolucci et al 2009;Lucas et al 2016).…”

Our study determines the reptile species richness, composition, and habitat use in three areas recovering from mining activity in addition to the adjacent pristine and anthropized areas of a priority region for biodiversity conservation of the Brazilian Cerrado. We also compared our data with published surveys on the Cerrado domain in order to identify areas with unique species composition and/or areas where the reptile composition is more homogeneous. The survey was conducted in the municipality of Niquelândia, northern Goiás state, central Brazil, and involved reptile samplings from different physiognomies and water bodies. We found 47 species, including one crocodilian, one chelonian, two amphisbaenians, 17 lizards, and 26 snakes. The list includes 37 species with large geographic distribution, occurring in other morphoclimatic domains, as well as 10 species which are endemic to the Cerrado. Some species recorded for the region are listed in the Appendices I and II of the CITES. Many reptile species were frequently associated with anthropogenic habitats, while others seem to depend on remnants of pristine habitats. Low similarity was found among the 32 sites considered across the Cerrado domain. Ten sites located in Cerrado regions in contact with the adjacent domains have unique reptile composition, whereas most sites largely located in the central area of the domain have reptile communities which are more homogeneous among them. It is important to conduct long-term studies to have patterns of reptile species composition recognized as well as population decline and/or local extinctions and effective reptile conservation actions, with focus on these sites considering their unique species.
