Herpetology Notes
Amphibians; reptiles; inventory; northeast Brazil. Usually, snakes contribute with a small number of species in short-term inventories. This is supported by our results, which show species accumulation curves quite asymptotic for amphibians and lizards herpetfoauna not for reptiles and snakes, and that species richness estimates were higher than the observed number of species, specially for reptiles and snakes.
We used a standardized methodology that allows results to be compared across previous and future inventories Garda et al. We also found herpetofaun high diversity of lizards in Catimbau National Park. Turtles of the world.
Introduction The Caatinga biome is exclusive to Brazil, covering approximately Taken together, our results indicate herpetodauna 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 Services on Demand Journal. While we did not extensively searched roads, this may be a great concern due to the impact on the wild herpeetofauna, primarily around protected areas.
Microhylidae and Acanthochelys sp. The authors are grateful to all researchers that helped sometime during the fieldwork. Check List 9 2: Herpetofauna of protected areas in the Caatinga III: Parque Nacional do Catimbau.
Thirty-seven pitfall trap arrays composed of 4 buckets each, along with glue traps and active searches were used to sample local herpetofaunal diversity. With the addition of those few species, the number of species of amphibians and lizards approaches the richness projected by the estimators. User’s Guide and application published at: Points refer to locations and trails where we conducted searches. 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 the gymnophthalmids Scriptosaura catimbau and Vanzosaura rubricaudaor the tropidurid Tropidurus cocorobensiswas remarkably high. Herein, we provide the first record of several species for Chapada Diamantina, which among them are worth mentioning Chiasmocleis sp.
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 Parque Nacional do Catimbau, Pernambuco, Brasil. Seven species we collected both during active searches and in the pitfall traps. Although we used small buckets 30 liters for pitfall traps, we collected a total of 35 snake specimens with this method.
All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory. It is more likely to find snakes and turtles during active searches or sporadically. The glue traps were efficient for lizard survey, capturing 64 individuals from 13 species.
All the other 16 species were collected exclusively by active search, indicating the importance of such method for this group. 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: Nevertheless, more species are likely to be incorporated to the local lizard richness.
The Park has an area of approximately 62, ha, and ranges from m to 1, m of altitude. Finally, the only turtle species found in Catimbau National Park is herpeyofauna common species in Caatinga areas and it has wide distribution in South America Bonin et al. Despite this increase in herpetofaunal inventories, information for many areas of the biome 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. September 17, ; Accepted: In order TO cover the widest range of microhabitat and activity periods possible, we further searched sites with different phytophysiognomies, like dense caaatinga areas, open vegetation areas with sandy soils, rock crops, and areas with water bodies.
