All the other 16 species were collected exclusively by active search, indicating the importance of such method for this group.
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 All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory.
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. Nevertheless, more species are likely to be incorporated to the local lizard richness. 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. Squamata, Gymnophtalmidae, Anotosaura vanzolinia Dixon, Also, the region is considered to be of extreme biological importance due its richness and endemism MMA All traps were checked daily.
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. 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. In addition, we used species richness estimators with nonparametric incidence-based estimators: Herein, we provide the first record of several species for Chapada Diamantina, which among them are worth mentioning Chiasmocleis sp.
Estimating terrestrial biodiversity through extrapolation. 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 herpstofauna other Caatinga sites.
The ecology of tropical lizards in the Caatinga of northeast Brazil. Herpetofauna of protected areas in the Caatinga IV: 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. Despite the increase in herpetofaunal inventories in the Caatinga biome, information for many areas is still lacking and new surveys are required.
User’s Guide and application published at: Although we used small buckets 30 liters for pitfall traps, we collected a total of 35 snake specimens with this method. Also, four snake species were only found and collected through active search Table 1.
How to cite this article. Of those, eigth species were recorded in the Catimbau National Park for the first time. However, snake richness will increase considerably with more sampling effort and consequently the number of reptiles will rise. Furthermore, the abundance of some species, such as herpdtofauna gymnophthalmids Scriptosaura catimbau and Vanzosaura rubricaudaor the tropidurid Tropidurus cocorobensiswas remarkably high.
With the addition of those few species, the number of species of amphibians and lizards approaches the richness projected by the estimators. Microhylidae and Acanthochelys sp.
Thirty-seven pitfall trap arrays composed of 4 buckets each, along with glue traps and active searches were used to sample local herpetofaunal diversity. The Park has an area of approximately 62, ha, and ranges from m to 1, m of altitude. Herpeetofauna recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian. 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 Check List 9 2: It is more likely to find snakes and turtles during active searches or sporadically.
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. Catainga species rarefaction curves were attained without replacement, using 1, randomizations. 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.
Herpetofauna of protected areas in the Caatinga III: The Catimbau National Park, Pernambuco, Brazil
Probably, new species will be added to the list, mostly those pertaining to biological groups difficult to access rapidly, such as snakes. The glue traps were efficient for lizard survey, capturing 64 individuals from 13 species. User Username Password Remember me. The herpetkfauna 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 species, 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.
Rarefaction curves and richness herpwtofauna suggest that local biodiversity is still underestimated. Changing the course of biodiversity conservation in the Caatinga of Northeastern Brazil. Check List 10 1: 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. Turtles of the world. Herpetofauna of protected areas in the Caatinga II:
