“…The regional lizard fauna is composed predominantly of species with wide distribution and endemic species from the Atlantic Rainforest biomes. Despite the existence of records of Heterodactylus imbricatus (Novelli et al 2011) and Urostrophus vautieri (Novelli et al 2012) in Cerrado, we still consider these species as endemic to the Atlantic Forest biome, since these records are from riparian forests in marginal areas of this biome. Considering this, there are five species endemic from Atlantic Rainforest in the Serra do Ouro Branco.…”

The present study evaluated the lizard fauna in Serra do Ouro Branco, Minas Gerais, Brazil, a transition area between the Atlantic Forest and Cerrado. Data was collected using pitfall traps, active and occasional encounters, and through information from zoological collections and the literature. Field sampling was performed in two stages over a period of 36 months: from December 2006 to December 2008, and from January to December 2010. The study area is home to 15 species belonging to eight families: Anguidae, Gekkonidae, Gymnophthalmidae, Leiosauridae, Polychrotidae, Mabuyidae, Teiidae, and Tropiduridae. Lizard species evaluated in this study represent a relevant asset for this zoological group inhabiting the transitional areas between the Atlantic Forest and Cerrado. They include strictly forest species and endemic Atlantic Forest species such as Ecpleopus gaudichaudii, Enyalius perditus and Heterodactylus imbricatus in addition to typical Cerrado taxa common to both biomes.

“…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.

Taxonomic, functional, and phylogenetic diversity of lizard assemblages across habitats and seasons in a Brazilian Cerrado area

One of the core issues in community ecology is the understanding of mechanisms that determine community structure. In this study, we examine how two structurally distinct habitats (campo sujoa grassy savanna habitat with low shrubby coverand seasonal semi-deciduous forest) and distinct hydrological seasons (dry and rainy) influence the taxonomic, functional and phylogenetic diversity of lizard assemblages in a savanna area in the Brazilian Cerrado. We used pitfall traps to sample lizards from May 2000 to February 2002. To quantify spatio-temporal changes in the lizard assemblages, we used parameters of taxonomic (species richness -SR), functional (functional diversity -SES.FD, functional redundancy -FR and functional dispersion -FDis), and phylogenetic diversity (phylogenetic species richness -PSR and phylogenetic species variability -PSV). We also estimate functional and phylogenetic structure of the assemblages in each habitat during dry and rainy seasons. We recorded 182 lizards distributed among 14 species. Species composition differed among habitat types, but did not differ seasonally within habitats. SES.FD, FDis, and FR also differed among habitat types but not among seasons, with SES.FD and FDis being greater in seasonal semi-deciduous forest, while FR was greater in campo sujo. SR, PSR, and PSV were not influenced by the factors analysed. The lizard assemblage of campo sujo was functionally clustered in the dry season and phylogenetically clustered in the rainy season. These results demonstrate that differences among habitat types and seasons are important in shaping the taxonomic, functional, phylogenetic diversity and structure of lizard assemblages in the savanna area studied. Our study also demonstrates the importance of using different measures of diversity to obtain a better understanding on the mechanisms that influence the lizard assemblages in a highly seasonal environment.
