Between November and December reptiles were captured.

In total 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. There was no species recorded that were common to the environments of Cerrado and Dirty Field but two species not sympatric en found of the same genus, Tropidurus torquatus, which was coopam 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. Durante um ano as armadilhas ficaram abertas ininterruptamente e foram amostradas horas de procura limitada por tempo. Reptiles form a prominent group in almost all terrestrial assemblages, with more than 10, cpoam species worldwide Uetz The greatest threats to Brazilian herpetofauna are concentrated in these phytogeographical domains and mainly result from habitat loss and degradation.

The remnants of the Atlantic Forest in Minas Gerais have been identified as being of interest for conservation because of high anthropogenic pressure caused by urbanization and deforestation Drummond et al. Similarly, the Cerrado has suffered sharp changes due to its conversion to pasture, monocultures or nd agricultural activities Drummond et al.

Xopam expansion of reptiles inventories Cruz et al. These studies have even shown that the distribution of some species is increasing Santos et al ; Novelli et al. 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.

Among the priority areas for biodiversity conservation in Minas Gerais that have been defined Drummond et al. The Serra region includes three protected areas administered by the State Forestry Institute: Above the altitude of m, the terrain consists predominantly of high meadows. The peaks of the range and a large part of its flanks are covered by nd fields vegetation, interrupted by gallery forest and small bodies sn latosol copsm Cerrado vegetation Silva et al. We sampled four types of vegetation: South of the mountains, traps were installed in two remote areas, 2.

The other region was located at the western end of the mountain, near the Mangue trail. The Squamata reptile sampling was conducted once a week between November and November Sets of pitfall traps were installed, with interception or guiding fences AQs as proposed by Greenberg et al. Each sampling point 11 of m of fence interception 1 m high10 funnel traps and five liter buckets, in alternating funnel and bucket pairs. A total of 10 sets of traps were installed in the four different vegetation types, thus totaling 50 AQs, FTs and m of guiding fence.

In addition to these sampling methods, trap specimens were also caught and collected through a limited-time search during the diurnal period from 8: Specimens found during maintenance tasks on the farm known as Coliseum weeding, maintenance of fence posts, planting and cleaning and during other everyday jobs in the region were also registered in the present study.


The specimens that were caught or collected alive were photographed and were mostly released near the capture site. Squamata with eyelids and at least traces of legs, which obviously do not constitute a monophyletic group. The taxonomy adopted was that of Frost et al. To identify specimens, field guides, keys and descriptions in papers Peters et al.

For Rn, a co;am by Pyron et al. Representative specimens are listed in Appendix 1. Statistical analyses were performed on species diversity and similarity between habitats. The richness of species of the four vegetation types sampled was compared by means of rarefaction curves in the EstimateS 9. The curves were generated through the bootstrap method, because this uses data on all species, i.

The richness in the four vegetation types sampled was compared by means of species rarefaction copan. Overall, the sampling effort for this study lasted for 12 months, involving uninterrupted open traps and 52 field trips, totaling hours of bucket sampling and hours of time-limited hunts.

We recorded a cppam of specimens belonging to 13 families and dopam species of Squamata reptiles: Clpam first-order jackknife estimators, the richness estimated for the study area, in the four vegetation types sampled was approximately 32 species Figures 4 and 5. None of the species rarefaction curves reached the asymptote.

Among the snakes, the family Dipsadidae was the richest, with a total of nine sampled 18.

Although fields with sparse shrubs were only sampled ocpam one point, this vegetation type presented important results because of the six species recorded at the sampling site, of which four were unique to this environment.

The only way to compare all the capture sets in this study was by means of capture efficiency, i. The other similarity values are shown in Table 4. The species with fossorial and subfossorial habits such as Leposternon dnnAtractus pantostictus and Micrurus lemniscatus were recorded only through the chance encounter method, as also were Chironius quadricarinatusSibynomorphus mikanii and S.

The only specimen of S. This method proved of highly important, especially with regard to snakes, because among the 16 species recorded, six were sampled only through chance 18 Table 5. It can be seen that the composition of the communities varied according to the vegetation gradient physiognomywhich is consistent with the pattern recorded by Nogueira et al.

Although the traps used for sampling Squamata in this study are not ideal for tree-dwelling species and semi-arboreal species, the most abundant species in this study E. According to Nogueira et al. These data corroborate those found in the present study. This makes it possible both for animals copxm of forest environments and for animals typical of open areas to occupy this type of habitat.

These authors studied the richness, fauna composition and local distribution of lizards in a 6, ha fragment in the Cerrado of central Brazil.

They found that the richness values, with cpoam sympatric species belonging to seven families outweighed most of the data from previous studies in Cerrado localities.

Representatives of the Squamata fauna studied here have been registered in other areas of the Cerrado, including Bothrops neuwiediCrotalus durissusChironius flavolineatusAmeivula ocelliferaEnyalius bilineatusOxyrhopus guibei and Xenodon merremii BaileyTeixeira-Filho et al. Among the lizards caught in the present study, only Salvator merianaeEcpleopus cipam and H.

However, Novelli et al. In the study by Cruz et al. These authors considered that these two species were endemic to the Atlantic Forest biome. The genus Ecpleopus is currently considered to be monotypic, consequent to its last review by Uzzell However, recent molecular studies have indicated that it has greater taxonomic complexity. The evidence suggests that the name E. This species was considered rare until a few years ago Eisemberg et al.


Other records of reptile fauna in transition regions between the Ocpam Forest and Cerrado in Minas Gerais, near the study area, were also consulted. However, in most studies in similar areas, the species richness sn greater than that presented in this survey Silveira et al, ; Costa et al, ; Copamm et al, ; Cross et al.

None of the rarefaction curves reached the full asymptote Figure 4which highlights the need for more studies and new data analysis methods, as seen in the study by Lopez et al. Other important factors that influence the sampled data include the methods used for sample capture and collection. The methods that were used in the present study are the ones that are most used.

However, further investments in searching for arboreal species are still needed, because this group was considered to be undersampled in this study. The species of Epicrates occurring in the collection area of the present 1118 Souza, may have been E.

Among the snakes found, five have medical importance: Accidents involving these snakes can be considered serious Cardoso et al. None of the species recorded in this study present any dh of threat on the IUCN listat national level Machado et al. During this study, threats to the reptile fauna were detected at the sampling sites.

The north face of the mountain range is subject to coapm anthropic pressure, such as wood-cutting activities and the presence of tracks and garbage resulting from tourism. Next to the region chosen for evaluation on the north side of the mountain range is the entrance to the Mangue trail, which is greatly used for crossing the mountain range.

Although the environments studied in the south of the APA are little affected by tourism, mainly because they are private areas, there coapm some pressure from hunters and there have been some reports of consumption of meat from Salvator merianae. Another threat to the local fauna that was noted is fires. According to reports from residents, such occurrences are common in the Copaam.
