Parque Nacional do Catimbau, Pernambuco, Brasil. All amphibians found in Catimbau National Park were anuran species distributed in seven families.
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 Check List 10 1: Squamata, Gymnophtalmidae, Anotosaura vanzolinia Dixon, With the addition of those few species, the number of species of amphibians and lizards approaches the richness projected by the estimators.
Herpetofauna of protected areas in the Caatinga III: Check List 9 2: Amphibians; reptiles; inventory; northeast Brazil.
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.
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. Usually, snakes contribute with a small number of species in short-term inventories. The authors are grateful to all researchers that helped sometime during the fieldwork. Herein, we provide the first record of several species for Chapada Diamantina, which among them are worth mentioning Chiasmocleis sp.
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.
Usually, snakes and turtles are not prone to be collected with specific traps. Isabella Mayara Monteiro de Carvalho Pedrosa, e-mail: We also found a high diversity of lizards in Catimbau National Park.
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. User Username Password Remember me. We attempted to show the great potential of Catimbau National Park, characterized by the richest herpetofauna surveyed in a core region of the biome, along with the presence of endemic species such as the worm snake Amphisbaena supranumeraria heepetofauna the limbless lizard Scriptosaura catimbauunderscoring the importance of the area for the conservation and maintenance of the Caatinga herpetofauna caatingw.
New records and geographic distribution map.
Herpetofauna of protected areas in the Caatinga IV: 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. 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.
The landscape is a typical Caatinga, with physiognomies such as dense arboreal Caatinga, shrubby spineless vegetation, sandy soils and rock fields, both evergreen and deciduous flora with plant species such as Caesalpinia ferrea, Ziziphus joazeiro, Orbignya phalerataBursera leptophloeos, as well as cacti and bromeliads Figueiredo et al. All traps were checked daily.
Herpetofauna of protected areas in the Caatinga III: The Catimbau National Park, Pernambuco, Brazil
A new genus and species of eyelid-less and limb reduced gymnophthalmid lizard from northeastern Brazil Squamata, Gymnophthalmidae. Turtles of the world.
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.
March 20, ; Revised: 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. 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 All the other 16 species were collected exclusively by active search, indicating the importance of such method for this group.
Estimating terrestrial biodiversity through extrapolation. We suggest that long-term studies in the area should be conducted, attempting to describe the entire herpetofauna of the region.
Caatjnga and Acanthochelys sp. Despite this increase in herpetofaunal inventories, information for many areas of the biome is still lacking and new surveys are required. However, a rapid increase in the last decades of long-term inventories for herpetoofauna localities has shown a much higher amphibian and reptile species richness and endemism than previously believed Rodrigues Historically, the Caatinga herpetofauna was considered impoverished and lacking character compared to forest biomes in South America Vanzolini et al.
We collected the two yerpetofauna of the mud-turtle Kinosternon scorpioides during the active searches. Herein, we present the results of a day inventory of the herpetofauna from the Catimbau National Park, in the semi-arid region of Pernambuco State. Finally, two species Amphisbaena alba and Philodryas olfersii were found killed on roads within and adjacent to the Catimbau National Park. Also, four snake species were only found and collected through active search Table 1.
Interpolating, extrapolating and comparing incidence-based species accumulation curves. Leiuperinae from Northeastern Brazil.
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. 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 with other Caatinga sites.
Amphibians and reptiles from a highly diverse area of the Caatinga domain: 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: It is more likely to find snakes and turtles during active searches or sporadically.
