In addition, we used species richness estimators with nonparametric incidence-based estimators: 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 catinga snakes.
Taken together, our results indicate that caatijga 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 Microhylidae and Acanthochelys sp. Squamata, Gymnophtalmidae, Anotosaura vanzolinia Dixon, Herpetofauna of protected areas in the Caatinga II: Probably, new species will be added to the list, mostly those pertaining to biological groups difficult to access rapidly, such as snakes.
Herpetofauna of protected areas in the Caatinga I: The inventory was conducted from March 13th to April 14th, We also carried random active searches for specimens, which were conducted in the morning, in the afternoon, and at night, in the following herpdtofauna and trails, locally knows as: We recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian.
All the other 16 species were collected exclusively by active search, indicating the importance of such method for this group. However, snake richness will increase considerably with more sampling effort and consequently the number of reptiles will rise.
The species rarefaction curves were attained without replacement, using 1, randomizations. Although we used small buckets 30 liters for pitfall traps, we collected a total of 35 snake specimens with this method.
Currently, there are more than squamate and amphibian species known for the Caatinga, many of which are endemic RodriguesDelfimand new endemic species are continuously being described Cruz et al. Additionally, we used glue traps distributed as quartets in each array of pitfall traps: 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.
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. Seven species we collected both during active searches and in the pitfall traps. Introduction The Caatinga biome is exclusive to Brazil, covering approximately 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 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 Services on Demand Journal.
Points refer to locations and trails where we conducted searches. Estimating terrestrial biodiversity through extrapolation. Amphibians and reptiles from a highly diverse area of the Caaitnga domain: It is more likely to find snakes and turtles during active searches or sporadically. Usually, snakes and turtles are not prone to be collected with specific traps. The glue traps were efficient for lizard survey, capturing 64 individuals from 13 species.
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. 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.
Herpetofauna of protected areas in the Caatinga III: The Catimbau National Park, Pernambuco, Brazil
A new genus and species of eyelid-less and limb herpetoofauna gymnophthalmid lizard from northeastern Brazil Squamata, Gymnophthalmidae. The ecology of tropical lizards in the Caatinga of northeast Brazil. The function of richness Mao Tau was calculated as the accumulation function of species throughout the number of collected individuals. Acknowledgements The authors are grateful to all researchers that helped sometime during the fieldwork.
Rarefaction curves and richness estimators suggest that local biodiversity is still underestimated. Finally, two species Amphisbaena alba and Philodryas olfersii were found killed on roads within and adjacent to the Catimbau National Park.
Parque Nacional do Catimbau. 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 species, such as Bufonidae and Odontophrynidae. Turtles of the world. March 20, ; Revised: Thirty-five pitfall trap arrays composed of 4 buckets each, coupled with glue traps, and haphazard searches were used to sample the herpetofaunal diversity.
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 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. All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory. The species rarefaction and richness estimators were constructed in EstimateS 9.
Herein, we provide the first record of several species for Chapada Diamantina, which among them are worth mentioning Chiasmocleis sp.
