All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory. Seven species we collected both during active searches and in the pitfall traps. Probably, new species will be added to the list, mostly those pertaining to biological groups difficult to access rapidly, such as snakes.
Thirty-seven pitfall trap arrays composed of 4 buckets each, along with glue traps and active searches were used to sample local herpetofaunal diversity.
Estimating terrestrial biodiversity through extrapolation. Parque Nacional do Catimbau, Pernambuco, Brasil.
Usually, in rapid inventories, snakes are harder to sample than lizards and frogs because they present secretive habits, low abundance, do not produce sound, and due to the lack of effective collecting methods Shine September 17, ; Accepted: Statistical estimation of species richness and shared species from herpetofaunw. Acknowledgements The authors are grateful to all researchers that helped sometime during the fieldwork. Historically, the Caatinga herpetofauna was considered impoverished and lacking character compared to forest biomes in South America Vanzolini et hetpetofauna.
With the addition of those few species, the number of species of herpetofxuna and lizards approaches the richness projected by the estimators. We recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian. 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.
Herpetofauna of protected areas in the Caatinga III: The Catimbau National Park, Pernambuco, Brazil
Also, the region is considered to be of extreme biological importance due its richness and endemism MMA The Park is included in the sedimentary deposits of Tacaratu formation, from the Paleozoic era, with the topography mainly uneven, due to strong intemperism Ferreira New records and geographic distribution map. Usually, snakes contribute with a small number of species in short-term inventories.
A new species of Pseudopaludicola Anura: March 20, ; Revised: However, a rapid increase in the last decades of long-term inventories for several localities has shown a much higher amphibian and reptile species richness and endemism than previously believed Rodrigues 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.
The lizard richness is higher than other Caatinga areas, which typically range from 14 to 21 species VittCavalcanti et al.
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. Furthermore, the abundance of some species, such as the gymnophthalmids Scriptosaura catimbau and Vanzosaura rubricaudaor the tropidurid Tropidurus cocorobensiswas herpetofaunw high. Thirty-five pitfall trap arrays composed of 4 buckets each, coupled with glue traps, and haphazard searches were used to sample the herpetofaunal diversity. ehrpetofauna
Herpetofauna of protected areas in the Caatinga II: The landscape is a typical Caatinga, with physiognomies such as dense arboreal Caatinga, shrubby spineless vegetation, sandy soils and rock fields, both evergreen and deciduous flora with plant species such as Caesalpinia ferrea, Ziziphus joazeiro, Orbignya phalerataBursera leptophloeos, as well as cacti and bromeliads Figueiredo et al. Herpetofauna of protected areas in the Caatinga III: Isabella Mayara Monteiro de Carvalho Pedrosa, e-mail: Squamata, Gymnophtalmidae, Anotosaura vanzolinia Dixon, Overview of the distribution of snakes of the genus Thamnodynastes Dipsadidae in northeastern Brazil, with new records and remarks on their morphometry and pholidosis.
We used a standardized methodology that allows results to be compared across previous and future inventories Garda et al.

We collected the two specimens of the mud-turtle Kinosternon scorpioides during the active searches. Check List 10 1: Despite the increase in herpetofaunal inventories in the Caatinga biome, information for many areas is still lacking and new surveys are required. Rarefaction curves and richness estimators suggest that local biodiversity is still underestimated.
The function of richness Mao Tau was calculated as the accumulation function of species throughout the number of collected individuals.
We suggest that long-term studies in the area should be conducted, attempting to describe the entire herpetofauna of the region. 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. All the other 16 species were collected exclusively by active search, indicating the importance of such method for this group.
Amphibians and reptiles from a highly diverse area of the Caatinga domain: However, snake richness will increase considerably with more sampling effort and consequently the number of reptiles will rise. All traps were checked daily.
Leiuperinae from Northeastern Brazil. The rarefaction curves Mao Tau did not reach stability Figure 9 and the various species richness estimators produced greater estimates than the observed richness for amphibians and reptiles, or also for individual estimates for lizards and snakes Table 2.
