Herpetofauna of protected areas in the Caatinga IV: Chapada Diamantina National Park, Bahia, Brazil. Felipe de Medeiros Magalhães, Daniel Orsi Laranjeiras. 9 jan. Herpetofauna em unidades de conservação da Caatinga III: Parque Nacional do Catimbau, Pernambuco, Brasil. Isabella Mayara Monteiro de. Oliveira Mesquita2, David Lucas Röhr1, Willianilson Pessoa da Silva1, Gustavo the Caatinga herpetofauna, especially for the region of.
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, Herpetoffauna phalerataBursera leptophloeos, as well as cacti and bromeliads Figueiredo 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.
The ecology of tropical lizards in the Caatinga of northeast Brazil. September 17, ; Accepted: In addition, we used species richness estimators with nonparametric incidence-based estimators: 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 and the limbless lizard Scriptosaura catimbauunderscoring the importance of the area for the conservation and maintenance of the Caatinga herpetofauna biodiversity.
Parque Nacional do Catimbau, Pernambuco, Brasil. 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: 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. The Park has an area of approximately 62, ha, and ranges from m to 1, m of altitude.
Also, four snake species were only found and collected through active search Table 1.
Points refer to locations and trails where we conducted searches. Also, the region is considered to be of extreme biological importance due its richness and endemism MMA Usually, in herpetofakna inventories, snakes are harder to sample than lizards and frogs because they present secretive habits, cawtinga abundance, do not produce sound, and due to the lack of effective collecting methods Shine 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.
Acknowledgements The authors are grateful to all researchers that helped sometime during the fieldwork. 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, herpetofuna as Bufonidae and Odontophrynidae.
Despite this increase in herpetofaunal inventories, information for many areas of the biome is still lacking and new surveys are required. We used 37 pitfall trap arrays divided into sa different trails, one in an open shrubby sa area with sandy soil and the other in a dense forest vegetation area.
We collected the two specimens of the mud-turtle Kinosternon scorpioides during the active searches.
We used a standardized methodology that allows results to be compared across previous and future inventories Garda et al. Seven species we collected both during active searches and in the pitfall traps. Amphibians; reptiles; inventory; northeast Brazil. Services on Demand Journal. However, snake richness will increase considerably with more sampling effort and consequently the number of reptiles heretofauna rise.
Those two species have their distributions almost confined to the Caatinga biome Coelho et al.
All traps were checked daily. The glue traps were efficient for lizard survey, capturing 64 individuals from 13 species.

All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory. Amphibians and reptiles from a highly diverse area of the Caatinga domain: The Caatinga biome is exclusive yerpetofauna Brazil, covering approximately Historically, the Caatinga herpetofauna was considered impoverished and lacking character compared to forest biomes in South America Vanzolini et al. Herpetofaunq the other 16 species were collected exclusively by active search, indicating the importance of such method for this group.

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. User’s Guide and application published at: We recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian. d
We also found a high diversity of lizards in Catimbau National Park. Turtles of the world.
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. Squamata, Gymnophtalmidae, Anotosaura vanzolinia Dixon, Usually, snakes contribute with a small number of species in short-term inventories. 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.
