“…Two of the three frogs endemic to the SMNR are brachycephalids, which is consistent with the overall pattern in Paraná, where most of the 17 endemic species are brachycephalids of the genus Brachycephalus (Haddad et al 2013). The populations of the Brachycephalus species are typically restricted to islands of montane forest (Pombal Jr. et al 1998;Ribeiro et al 2005;Alves et al 2006) surrounded by valleys, which promote intense isolation and facilitate allopatric speciation (Pie et al 2013), as probably occurred in the case of Brachycephalus tridactylus in the SMNR and some other members of this genus in southern Brazil (Ribeiro et al 2015).…”

Abstract:We provide an updated checklist of the anurans of the Salto Morato Nature Reserve (SMNR), Paraná, southern Brazil, including information on species endemism, conservation status, habitat use, and reproductive modes. We sampled the study area between February 2013 and July 2015, using Visual Encounter Surveys, totaling 700 hours of sampling effort. We supplement our primary data with secondary data (published papers and voucher specimens), and through these, we found a total of 54 anuran species representing 23 genera and 10 families. All the frogs recorded are endemic to the Atlantic Forest. Although no species has been listed as Endangered on the Red Lists of Paraná state, Brazil, and the IUCN, five are classified as Data Deficient. Most of the species recorded were arboreal (55.5%), a third were terrestrial (33.3%), and the remainders were rheophilic (11.1%). We identified 18 different reproductive modes, with types 1 (lay eggs in lentic water where the tadpoles develop) and 23 (direct development of terrestrial eggs) being the most common. Our findings indicate that the SMNR currently has the greatest diversity of anuran species and reproductive modes of any area in southern Brazil.

“…Brachycephalus Fitzinger, 1826 is a remarkable genus of miniaturized frogs endemic to the Brazilian Atlantic Forest (Pie et al, 2013; Bornschein et al, 2016). Brachycephalus species often display an extraordinarily high level of endemism, with one or a few adjacent mountaintops representing the entire known geographical ranges of many species (e.g., Ribeiro et al, 2015; Bornschein et al, 2016).…”

“…Brachycephalus species often display an extraordinarily high level of endemism, with one or a few adjacent mountaintops representing the entire known geographical ranges of many species (e.g., Ribeiro et al, 2015; Bornschein et al, 2016). Such extreme endemism is probably due to their particular cold/humid environmental requirements found in high-elevation regions, as in the case of cloud forests (see Pie et al, 2013; Bornschein et al, 2016). Firkowski et al (2016) recently studied the process of diversification of montane Brachycephalus species using a combination of species delimitation methods and molecular divergence dating.…”

A new species of Brachycephalus (Anura: Brachycephalidae) is described from the Atlantic Forest of northeastern state of Santa Catarina, southern Brazil. Nine specimens (eight adults and a juvenile) were collected from the leaf litter of montane forests 790–835 m above sea level (a.s.l.). The new species is a member of the pernix group by its bufoniform shape and the absence of dermal co-ossification and is distinguished from all its congeners by a combination of its general coloration (dorsal region of head, dorsum, legs, arms, and flanks light, brownish green to dark, olive green, with darker region in the middle of the dorsum and a white line along the vertebral column in most specimens) and by its smooth dorsum. The geographical distribution of the new species is highly reduced (extent of occurrence estimated as 25.04 ha, or possibly 34.37 ha). In addition, its habitat has experienced some level of degradation, raising concerns about the future conservation of the species. Preliminary density estimates suggest one calling individual every 3–4 m2 at 815–835 m a.s.l. and every 100 m2 at 790 m a.s.l. Together with the recently described B. boticario and B. fuscolineatus, the new species is among the southernmost species of Brachycephalus known to date.

“…No data are available on the population trends of other brachycephalids, i.e., B. pombali and I. spanios (IUCN 2017). The populations of the Brachycephalus species are typically restricted to fragments of hill forests (Pombal et al 1998, Ribeiro et al 2005, Alves et al 2006), separated by valleys, which isolates the populations (Pie et al 2013) and makes them difficult to survey effectively. In the case of the bufonids, Dendrophryniscus stawiarskyi, for example, is known only from three specimens collected in the early 1980s, and there is currently no information on its population status, while the species of the genus Melanophryniscus, M. alipioi and M. tumifrons (Boulenger, 1905), are extremely difficult to survey, although the former species is commonly encountered during the breeding season (IUCN 2017).…”

Anuran amphibians in state of Paraná, southern Brazil

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.
