Abstract:The present work is a survey of the herpetofauna of Carlos Botelho State Park (CBSP), located in the region of Serra de Paranapiacaba, State of São Paulo, Brazil. Data were gathered from specimens collected in six areas within the park during a period of 76 days distributed in one year, and from three Brazilian scientific collections. We also offer photographs and information on the biology and occurrence of species within the park and among Brazilian biomes. The herpetofauna of CBSP may be considered one of the most diverse in the State of São Paulo, with 65 species of amphibians and 59 species of reptiles recorded in the present study. From the 65 species of amphibia recorded, 84% (55 spp.) are endemic from forested areas of the Atlantic forest. We also distinguished different altitudinal patterns within the amphibian assemblage, with 46% being recorded only at altitudes above 500 m, while 9% are exclusive of areas under 400 m and 45% occur in all altitudes within the park. The reptile fauna of PECB is composed of 59 species, including 10 species of lizards, 48 snakes, and one chelonian. Among the snakes collected at the CBSP, the Lancehead Bothrops jararaca was the most frequent, with 26,9% (N = 14) of the total of the collected specimens. Species that are considered difficult to sample, such as Echinanthera cephalostriata (13,5%; N = 7) and Taeniophallus affinis (7,7%; N = 4), were also numerous in PECB. Among lizards, Enyalius iheringii was the most abundant species, representing 50% (N = 16) of sampled specimens. We also performed a cluster analysis comparing 25 amphibian assemblages from different localities in the Atlantic Forest, and including the PECB, which resulted in the clustering of four main groups. The anurofauna of PECB presented high similarity with the assemblages of Jacupiranga (0,68) and Intervales (0,66) State Parks. These places are geographically close and constitute one of the largest preserved forest fragments of Atlantic rainforest in Brazil. The present work provides at the first time a list of reptiles for the CBSP, and complements the knowledge about the amphibian fauna at the CBSP. Resumo: O presente trabalho consiste em um inventário da herpetofauna do Parque Estadual Carlos Botelho (PECB), localizado na região da Serra de Paranapiacaba, Estado de São Paulo. Os dados foram obtidos por meio de coletas em seis áreas dentro do PECB durante um período de 76 dias distribuídos em um ano, e também por meio de consulta a coleções científicas para obtenção de dados secundários. São apresentados resultados sobre a biologia e ocorrência das espécies no PECB e no Brasil, além de fotografias das diferentes espécies que compõem a herpetofauna do PECB. A herpetofauna do PECB pode ser considerada uma das mais diversificadas de São Paulo, com 65 espécies de anfíbios confirmadas e 59 espécies de répteis registrados neste trabalho. Das 65 espécies de anfíbios, 84% (55 spp.) são endêmicas das formações florestais da Mata Atlântica. Devido às características do relevo do PECB, foram encontra...

“…asper by the first time by in the municipality of Guaraqueçaba may have been a mistake. Some years previously, Lingnau et al (2008) described this species from a nearby municipality in the state of Paraná, Morretes, which is less than 90 km from Guaraqueçaba, and discussed the geographic distribution of Hylodes asper (Müller, 1924). For many years, herpetologists believed that the geographic range of H. asper extends from the state of Santa Catarina to the state of Rio de Janeiro, although this species has often been confused with H. perplicatus (Miranda-Ribeiro, 1926) (Lingnau et al 2008).…”

Anuran amphibians in state of Paraná, southern Brazil

2018

View full text Add to dashboard Cite

The state of Paraná, located in southern Brazil, was originally covered almost entirely by the Atlantic Forest biome, with some areas of Cerrado savanna. In the present day, little of this natural vegetation remains, mostly remnants of Atlantic Forest located in the coastal zone. While some data are available on the anurans of the state of Paraná, no complete list has yet been published, which may hamper the understanding of its potential anuran diversity and limit the development of adequate conservation measures. To rectify this situation, we elaborated a list of the anuran species that occur in state of Paraná, based on records obtained from published sources. We recorded a total of 137 anuran species, distributed in 13 families. Nineteen of these species are endemic to the state of Paraná and five are included in the red lists of the state of Paraná, Brazil and/or the IUCN. Two anuran species were categorized as Near Threatened by the IUCN and 27 species were listed as Data Deficient in one or more lists. According to IUCN 49.6% of the anuran species recorded had their population trends stable, 19% in declined, only 1.4% is increased and 20.4% had your population trends unknown. We also recorded the occurrence in Paraná of the exotic invader anuran Lithobates catesbeianus. We consider our list of species to be a relatively reliable estimate of the anuran diversity of the Brazilian state of Paraná, although new species records are expected, mainly because there are many regions that have not yet been sampled. Keywords: Atlantic Forest, checklist, Cerrado, inventory, species richness. Anfíbios anuros do estado do Paraná, sul do BrasilResumo: O estado do Paraná, localizado no sul do Brasil, originalmente possuía praticamente toda sua área coberta pelo bioma Mata Atlântica com algumas porções do bioma Cerrado. Atualmente, pouco resta das formações destes biomas, sendo a maior parte remanescentes florestais de Mata Atlântica, localizados na região costeira do Estado. Apesar de haver estudos sobre anuros no estado do Paraná, até então nenhum deles proveu uma lista dos anuros com ocorrência no Estado, o que pode dificultar o conhecimento sobre a potencial diversidade de anuros e restringir medidas de conservação. A partir dessa lacuna, elaboramos uma lista das espécies de anuros com registro para o Paraná, a partir de dados de estudos publicados. Registramos um total de 137 espécies de anuros, pertencentes a 13 famílias. Dentre estas, 19 espécies de anuros são endêmicas do estado do Paraná e cinco encontram-se relacionadas sob algum grau de ameaça de extinção na lista vermelha do estado do Paraná, do Brasil e/ou da lista global da IUCN. Duas espécies de anuros foram categorizadas como Quase Ameaçada pela IUCN e 27 espécies foram listadas como Dados Insuficientes nestas listas. De acordo com a IUCN, 49,6% das espécies de anuros registradas apresentaram tendências populacionais estáveis, 19% diminuíram, apenas 1,4% aumentaram e 20,4% apresentaram tendências de sua populações desconhecidas.

“…The new species is distinguished from all other species in the genus by the following combination of characters: (1) thumbs without nuptial excrescences; (2) oblique lateral fold continuously extending from supratympanic fold to groin; tubercles absent ventrally to the oblique lateral fold; (3) light oblique lateral stripes usually evident from shoulder to groin, which become gradually more apparent as they approach the posterior part of the body; (4) venter mainly light with anastomosed or small dark spots weakly defined (Fig. 2B); (5) small size (SVL of males 5 22.9-25.8 mm, and SVL of females 5 26.4-28.0 mm; variation reported in Table 3); (6) paired lateral vocal sacs, which widely expand externally in adult males; (7) advertisement call with the following parameters: call duration 5 1.36-3.83 s; intercall duration5 5.91-19.42 s; Pavan et al 2001;Lingnau et al 2008; personal observations), a continuous oblique lateral fold, an evident light oblique lateral stripe, and absent tubercles ventral to the oblique lateral fold (species within the H. nasus group exhibit light tubercles scattered in the oblique lateral region and lack an oblique lateral fold and light oblique lateral stripe; Pavan et al 2001;Lingnau et al 2008;personal observations Table 4). The call notes of H. amnicola are emitted at a higher rate (18.1/s) and in shorter duration (0.015-0.034 s; Pombal et al 2002).…”

“…Hylodes species are rheophilic with reproductive biology strongly associated with fast streams (Nascimento et al 2001;Pombal et al 2002;Lingnau et al 2008). Few Hylodes species have been observed in courtship and spawning, but past studies have already revealed that their reproductive mode involves aquatic unpigmented eggs and early larval stages in an underwater constructed chamber and exotrophic tadpoles in lotic water (e.g., Haddad and Giaretta 1999;Haddad and Prado 2005;Narvaes and Rodrigues 2005).…”
