Herpetofauna of protected areas in the Caatinga III: Finally, the only turtle species found in Catimbau National Park is a common species in Caatinga areas and it has wide distribution in South America Bonin et al. 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.

All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory. Herpetofauna of protected areas in the Caatinga II: Propostas para o Bioma Caatinga. Herein, we provide the first record of several species for Chapada Diamantina, which among them are worth mentioning Chiasmocleis sp.

Despite the increase in herpetofaunal inventories in the Caatinga biome, information for many areas is still lacking and new surveys are required. Probably, new species will be added to the list, mostly those pertaining to biological groups difficult to access rapidly, such as snakes.

The Park has an area of approximately 62, ha, and ranges from m to 1, m of altitude. Thirty-five pitfall trap arrays composed of 4 buckets each, coupled with glue traps, and haphazard searches were used to sample the herpetofaunal diversity. 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.

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 All amphibians found in Catimbau National Park were anuran species distributed in seven families.

In addition, we used species richness estimators with nonparametric incidence-based estimators: The Caatinga biome is exclusive to Brazil, covering approximately Despite these findings, our rarefaction curves suggest that local biodiversity is still underestimated, which reinforces the need for future inventories in this and in less studied sites along this region.

Finally, the number of endemic and undescribed species herpetofxuna in this study provides additional evidence of the importance of Chapada Diamantina for the maintenance and conservation of the herpetofauna within the Caatinga domain.

Additionally, we used glue traps distributed as quartets in each array of pitfall traps: Also, four snake species were only found and collected through active search Table 1. We recorded 15 species of lizards, 4 amphisbaenas, 23 snakes, 2 chelonians and 31 frogs. The function of richness Mao Tau was calculated as the accumulation function of species throughout the number of collected individuals.

A new species of Pseudopaludicola Anura: The authors are grateful to all researchers that helped sometime during the fieldwork. In this study, our principal goal, using the same methodology to describe and compare the herpetofauna of the protected areas in Caatinga biome has been reached see Garda et al.

Nevertheless, more species are likely to be incorporated to the local lizard richness. Services on Demand Journal. Additionally, we attempted to show the herpetofuna potential of Catimbau National Park in harboring an important herpetofaunal Caatinga diversity, characterized by the richest herpetofauna surveyed in a core region of the biome.

Herpetofauna of protected areas in the Caatinga I: Overview of the distribution of snakes of the genus Thamnodynastes Dipsadidae in northeastern Brazil, with new records and remarks on their morphometry and pholidosis. For lizards, four species were only collected through active search Table 1 and three species were only caught with herpetoafuna traps, dda two amphisbaenians and the tiny gecko Coleodactylus meridionalis.

We also found a high diversity of lizards in Catimbau National Park.

Herpetology Notes

Introduction The Caatinga biome is exclusive to Brazil, covering approximately We recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian. Amphibians and reptiles from a highly diverse area of the Caatinga domain: Herein, we present the results of a day inventory of the herpetofauna from the Catimbau Herptofauna Park, in the semi-arid region of Pernambuco State.

Statistical estimation of species richness and shared species from samples.

Although we used small buckets 30 liters for pitfall traps, we collected a total of 35 snake specimens with this method. With the addition of those caatinag species, the number of species of amphibians and lizards approaches the richness projected by the estimators.

The lizard richness is higher than other Caatinga areas, which typically range from 14 to 21 species VittCavalcanti et al. However, snake richness will increase considerably with more sampling effort and consequently the number of reptiles will caainga. 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.

Seven species we collected both during active searches and in the pitfall traps. All traps were checked daily. Despite this increase in herpetofaunal inventories, information for many areas of the biome is still lacking and new surveys are required.
