In addition, our work reinforces the importance of the Park in conserving and maintaining Caatinga biodiversity, and new efforts to a better preservation and management of the National Park are certainly recommended. Herein, we provide the first record of several species for Chapada Diamantina, which among them are worth mentioning Chiasmocleis sp.

Rarefaction curves and richness estimators suggest that local biodiversity is still underestimated. User’s Guide and application published at: Our aims were to 1 provide a list based on an intensive effort conducted over a whole month; 2 contribute to the knowledge of the Caatinga herpetofauna, and 3 contextualize the results comparing, when possible, the richness and abundance of squamates and amphibians with other Caatinga sites.

Propostas para o Bioma Caatinga. Taken together, our results indicate that the Central Pernambuco region has the highest known herpetofaunal richness within the Caatinga and that Catimbau National Park is a key area for Caatinga biodiversity conservation Rodrigues Estimating terrestrial biodiversity through extrapolation.

Furthermore, the abundance of some species, such as the gymnophthalmids Scriptosaura catimbau and Vanzosaura rubricaudaor the tropidurid Tropidurus cocorobensiswas remarkably high.

Parque Nacional do Catimbau, Pernambuco, Brasil. While we did not extensively searched roads, this may be a great concern due to the impact on the wild fauna, primarily around protected areas. Although we used small buckets 30 liters for pitfall traps, we collected a total of 35 snake specimens with this method. We suggest that long-term studies in the area should be conducted, attempting to describe the entire herpetofauna of the region. Historically, the Caatinga herpetofauna was considered impoverished and lacking character compared to forest biomes in South America Vanzolini et al.

Thirty-five pitfall trap arrays composed caattinga 4 buckets each, coupled with glue traps, and haphazard searches were used to sample the herpetofaunal diversity. Herpetofauna of protected areas in the Caatinga III: In order TO cover the widest range of microhabitat and activity periods possible, we further searched sites with different phytophysiognomies, like dense vegetation areas, open vegetation areas with sandy soils, rock crops, and areas with water bodies.

Herpetofauna of protected areas in the Caatinga III: The Catimbau National Park, Pernambuco, Brazil

However, caaginga richness will increase considerably with more sampling effort and consequently the number of reptiles will rise. The species rarefaction and richness estimators were constructed in EstimateS 9. Usually, in rapid inventories, snakes are harder to sample than lizards and frogs because they present secretive jerpetofauna, low abundance, do not produce sound, and due to the lack of effective collecting methods Shine The glue traps were efficient for lizard survey, capturing 64 individuals from 13 species.

Additionally, we used glue traps distributed as quartets in each array of pitfall traps: Amphibians and reptiles from a highly diverse faatinga of the Caatinga domain: The rarefaction curves Mao Tau did not reach stability Figure 9 and the various species richness caatihga produced greater estimates than the observed richness for amphibians and reptiles, or also for individual estimates for lizards and snakes Table 2.

We used 37 pitfall trap arrays divided into two different trails, one in an open shrubby vegetation area with sandy soil and the other in a dense forest vegetation area. Those two species have their distributions almost confined to the Caatinga biome Coelho et al. Parque Nacional do Catimbau.

We also found a high diversity of lizards in Catimbau National Park. Abstract We provide a list of amphibians, lizards, chelonians, and snakes cawtinga during a day expedition to the northern portion of Chapada Diamantina National Park, Palmeiras municipality, Bahia State, Brazil.

All amphibians found in Catimbau National Park were anuran species distributed in seven families. The Park has an area of approximately 62, ha, and ranges from m to 1, m of altitude.

For lizards, four species were only collected through active search Table 1 and three species were only caught with pitfall traps, including two amphisbaenians and the tiny gecko Coleodactylus meridionalis. Statistical estimation of species richness and shared species from samples. Usually, snakes and turtles are not prone to be collected with specific traps. Check List 9 2: All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory.

Finally, the only turtle species found caqtinga Catimbau National Park is a common species in Caatinga areas and it has wide distribution in South America Bonin et heerpetofauna.

Seven species we collected both during active herpetofauba and in the pitfall traps.

Turtles of the world. March 20, ; Revised: Results and Discussion We recorded 1, individuals pertaining to 37 species of reptiles 25 lizards, three amphisbaenians, 11 snakes, and one chelonian and 21 species of amphibians Table 1Figures 3 – 8. We used a standardized methodology that allows results to be compared across previous and future inventories Garda et al.

Thirty-seven pitfall trap arrays composed of 4 buckets each, along with glue traps and active searches were used to sample local herpetofaunal diversity.
