March 20, ; Revised: 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.

New records and geographic distribution map. Despite the increase in herpetofaunal inventories in the Caatinga biome, information for many areas is still lacking and new surveys are required. Estimating terrestrial biodiversity through extrapolation. The composition of amphibian families is similar to other surveys in the Caatinga core region Garda et alArzabe et alwith species distributed in families with a dominance of Hylidae and Leptodactylidae, followed by other families with herpetofaunaa, such as Bufonidae and Odontophrynidae.

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. How to cite this article. This is supported by our results, which show species accumulation curves quite asymptotic for amphibians and lizards but not for reptiles and snakes, and that species richness estimates were higher than the observed number of species, specially for reptiles and snakes.

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

We recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian. Overview of the distribution of snakes of the genus Thamnodynastes Dipsadidae in northeastern Herletofauna, with new records and remarks on their morphometry and pholidosis. Rarefaction curves and richness estimators suggest that local biodiversity is still underestimated.

With the addition of those few species, the number of species of amphibians and lizards approaches the richness projected by the estimators. The function of richness Mao Tau was calculated as the accumulation function of species throughout the number of collected individuals.

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

It is more likely to find snakes and turtles during active searches or sporadically. Check List 10 1: Points refer to locations and trails where we conducted searches. Additionally, we attempted to show the great 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. Parque Nacional do Herpetofaunaa. Results and Discussion We recorded 1, individuals pertaining to 37 species of reptiles 25 lizards, three amphisbaenians, 11 snakes, and hdrpetofauna chelonian and 21 species of amphibians Table 1Figures 3 – 8.

Faatinga reptiles; inventory; northeast Brazil. September 17, ; Accepted: Those two species have their distributions almost confined to the Caatinga biome Coelho et al. We suggest that long-term studies in the area should be conducted, attempting to describe the entire herpetofauna of the region.

The rarefaction curves Mao Tau did not reach stability Figure 9 herpstofauna 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.

Probably, new species will be added to the list, mostly those pertaining to biological groups difficult to access rapidly, such as snakes. Squamata, Gymnophtalmidae, Anotosaura vanzolinia Dixon, Amphibians and reptiles from a highly diverse area of the Caatinga domain: Additionally, we used glue traps distributed as quartets in each array of pitfall traps: The Park has an area of approximately 62, ha, and ranges from m to 1, m of altitude.

Finally, two species Amphisbaena alba and Philodryas olfersii were found killed on roads within and adjacent to the Catimbau National Park.

Herpetology Notes

Introduction The Caatinga biome is exclusive to Brazil, covering approximately Out of 21 amphibian species, we collected only five of them with pitfall traps as well as through active search Table 1. Check List 9 2: The Caatinga biome is exclusive to Brazil, covering approximately Although we used small buckets 30 liters for pitfall traps, we collected a total of 35 snake specimens with this method.

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.
