In addition, we used species richness estimators with nonparametric incidence-based estimators: With the addition of those few species, the number of species of amphibians and lizards approaches the richness projected by the estimators. Also, four snake species were only found and collected through active search Table 1. We suggest that long-term studies in the area should be conducted, attempting to describe the entire herpetofauna of the region.

Herpetofauna of protected areas in the Caatinga IV: The ecology of tropical lizards in the Caatinga of northeast Brazil. Leiuperinae from Northeastern Brazil. Although we used small buckets 30 liters for pitfall traps, we collected a total of 35 snake specimens with this method. The lizard richness is higher than other Caatinga areas, which typically range from 14 to 21 species VittCavalcanti et al.

Abstract We provide a list of amphibians, lizards, chelonians, and snakes collected during a day expedition to the northern portion of Chapada Diamantina National Park, Palmeiras municipality, Bahia State, Brazil. Amphibians; reptiles; inventory; northeast Brazil. Additionally, we used glue traps distributed as quartets in each array of pitfall traps: We also found a high diversity of lizards in Catimbau National Park.

Despite this increase in herpetofaunal inventories, information for many areas of the biome is still lacking and new surveys are required.

Herpetofauna of protected areas in the Caatinga II: 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. However, snake richness will increase considerably with more sampling effort and consequently the number of reptiles will rise.


The function of richness Mao Tau was calculated as the accumulation function of species throughout the number of collected individuals. Check List 10 1: 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.

Herpetology Notes

Interpolating, extrapolating and comparing incidence-based species accumulation curves. Herpetofauna of protected areas in the Caatinga I: A new species of Pseudopaludicola Anura: We also carried random active searches for specimens, which were conducted in the morning, in the afternoon, and at night, in the following locations and trails, locally knows as: 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.


Propostas para o Bioma Caatinga. Also, the region is considered to be of extreme biological importance due its richness and endemism MMA Statistical estimation of species richness and shared species from samples. Despite these findings, our rarefaction curves suggest that local biodiversity is still underestimated, which reinforces hefpetofauna need for future inventories in this and in less studied sites along this region.

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 1Herpetodauna 3 – 8.

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

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

Out of 21 amphibian species, we collected only five of them with pitfall traps as well as through active search Table 1.

How to cite this article. 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.


Changing the course of biodiversity conservation in the Caatinga of Northeastern Brazil. User’s Guide and application published at: Microhylidae and Acanthochelys sp. All the other 16 species were collected exclusively by active search, indicating the importance of such method for this group. 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 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.

Estimating terrestrial biodiversity through extrapolation. Those two species have their distributions almost confined to the Caatinga biome Coelho et al.

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.

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. The Caatinga biome is exclusive to Brazil, covering approximately Herpetofauna of protected areas in the Caatinga III: 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. 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.
