This is supported by our results, which show species accumulation curves quite asymptotic for amphibians and lizards but not for reptiles caatinba snakes, and that species richness estimates were higher than the observed number of species, specially for reptiles and snakes.
Isabella Mayara Monteiro de Carvalho Pedrosa, e-mail: Amphibians and reptiles from a highly diverse area of the Caatinga domain: All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory. All amphibians found in Catimbau National Park were anuran species distributed in seven families.
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. Of those, eigth species were recorded in the Catimbau National Park for the first time. However, snake richness herpftofauna increase considerably with more sampling effort and consequently the number of reptiles will rise.
Herpetofauna of protected areas in the Caatinga III: 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. Probably, new species will be added to the list, mostly those pertaining to biological groups difficult to access rapidly, such as snakes.
Seven species we collected both during active searches and in the pitfall traps. Also, the region is considered to be of extreme biological importance due its richness and endemism MMA Introduction The Caatinga biome is exclusive to Brazil, covering approximately We recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian.
We recorded 15 species of lizards, 4 amphisbaenas, 23 snakes, 2 chelonians and 31 frogs. Herein, we present the results of caatingaa day inventory of the herpetofauna from the Catimbau National Park, in the semi-arid region of Pernambuco State. We also found a high diversity of lizards in Catimbau National Park. Herpetofauan we used small buckets 30 liters for pitfall traps, we collected a total of 35 snake specimens with this method.
Parque Nacional do Catimbau, Pernambuco, Brasil. 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 herpetofxuna of the area for the conservation and maintenance of the Caatinga herpetofauna biodiversity. Propostas para o Bioma Caatinga.
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 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.
Overview of the caaringa of snakes of the genus Thamnodynastes Dipsadidae in northeastern Brazil, with new records and remarks on their morphometry and pholidosis. All traps were checked daily. 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 In this study, our caatinfa goal, using the same methodology to describe and compare the herpetofauna of the protected areas in Caatinga biome has been reached see Garda et al.
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.
Herpetofauna of protected areas in the Caatinga IV: Estimating terrestrial biodiversity through extrapolation. Check List 10 1: Usually, snakes and turtles are not prone to be collected with specific traps.
Herpetofauna of protected areas in the Caatinga III: The Catimbau National Park, Pernambuco, Brazil
The species rarefaction curves were attained without replacement, using 1, randomizations. Points refer to locations and trails where we conducted searches. The function of richness Mao Tau was calculated as the accumulation function of species throughout the number of collected individuals. 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.
The Park has an area of approximately 62, ha, and ranges from m to 1, m of altitude. The lizard richness is higher than other Caatinga areas, which typically range from 14 to 21 species VittCavalcanti et al.
User’s Guide and application published at: Additionally, we attempted to show the great potential of Catimbau National Park in harboring an important herpetofaunal Caatinga diversity, characterized by the herpeotfauna herpetofauna surveyed in a core region of the biome.
Results and Discussion We recorded 1, individuals pertaining to 37 species of reptiles 25 lizards, three amphisbaenians, 11 snakes, caatonga one chelonian and 21 species of amphibians Table 1Figures 3 – 8. We collected the two specimens of the mud-turtle Kinosternon scorpioides during the active searches.
Leiuperinae from Northeastern Brazil. It is more likely to find snakes and turtles during active searches or sporadically.
Despite this increase in herpetofaunal inventories, information for many areas of the biome is still lacking and new surveys are required. Statistical estimation of species richness and shared species from samples. While we did not extensively searched roads, this may be herprtofauna great concern due to the impact on the wild fauna, primarily around protected areas. Herpetofauna of protected areas herpetofana the Caatinga II: In herpetofayna, we used species richness estimators with nonparametric incidence-based estimators: However, a rapid increase in the last decades of long-term inventories for several localities has shown a much higher amphibian and reptile species richness and endemism than previously believed Rodrigues All the other 16 species were collected exclusively by active search, xaatinga 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: Thirty-seven pitfall trap arrays composed of 4 buckets each, along with glue traps and active searches were used to sample local herpetofaunal diversity.
