“…Our results support other studies conducted in Cerrado areas (Brasileiro et al 2008, Oda et al 2009, Roberto et al 2013, Dal Vechio et al 2013, Santoro & Brandão 2014, Dória et al 2015, which affirm that the amphibian communities are dominanted by tolerant and generalist species. However, we recorded also typical species of forested areas, as Osteocephalus taurinus and B. boans, common species in riparian forests of the Cerrado and the Amazon biomes , Jungfer et al 2013, Matavelli et al 2013, Freitas et al 2017.…”

Similarly, acoustic differences between species of the genus Elachistocleis are almost undetectable to human ear, which prevented the identification of the species from this genus in the PEM because they were recorded only by their vocalizations and because there is the possibility that occur at least three species in region: E. piauiensis, E. carvalhoi and E. bumbameuboi (Caramaschi 2010).…”

Anurans of the Parque Estadual do Mirador, a remnant of Cerrado in the state of Maranhão, Northeastern Brazil

2017

The Cerrado is one of the most threatened biomes in Brazil. It is estimated that much of its original vegetation has been replaced by some type of human use. This is quite worrying, mainly in the northern part where the number of wildlife inventories is insufficient and creates the false impression of low diversity in the region. The Parque Estadual do Mirador-PEM, located in the south-central region of the state of Maranhão, presents vegetation typical of the Cerrado biome and corresponds to one of 46 priority areas for conservation in the state. Herein, we describe the species richness and composition of the anurofauna from the PEM and analyze the influence of different types of vegetation in its formation. Our inventory was conducted from December 2013 to February 2015, using the active search and auditory census methods on breeding sites in different water bodies of the park. We recorded 31 anuran species belonging to five families (species number in parentheses): Leptodactylidae (14), Hylidae (12), Bufonidae (3), Microhylidae (1) and Phyllomedusidae (1). The rarefaction curve and species richness estimators indicated that the sampling effort was enough to record most of the species in the region. The richness of anurans in the PEM was higher than reported by other authors for several areas of Cerrado. Most species have a wide distribution in Brazil or are strongly associated with the Caatinga or Amazon biomes. Only about 19% are endemic to the Cerrado biome. This study is the first to inventory the anurans species of the south-central region of state of Maranhão and provides important data on amphibian communities from the northern part of the Brazilian Cerrado.Keywords: inventory, Amphibia, Anura, conservation unit, species richness. Anfíbios anuros do Parque Estadual do Mirador, um remanescente de Cerrado no estado do Maranhão, nordeste do BrasilResumo: O Cerrado é um dos biomas mais ameaçados do Brasil. Estima-se que grande parte da cobertura vegetal original deste bioma tenha sido substituída por alguma forma de utilização humana. Este fato é bastante preocupante, principalmente na porção norte, onde o número de inventários faunísticos é insuficiente e gera a falsa impressão de baixa diversidade na região. O Parque Estadual do Mirador-PEM, localizado na região centro-meridional do Maranhão, apresenta vegetação típica do Cerrado e corresponde a uma das 46 áreas prioritárias para conservação no estado. Aqui, nós descrevemos a riqueza e a composição da anurofauna no PEM, analisando a influência dos diferentes tipos vegetacionais na sua formação. Inventariamos a anurofauna de dezembro de 2013 a fevereiro de 2015, utilizando métodos de procura ativa e censo auditivo em sítios reprodutivos de diferentes corpos d'água do parque.

Anuran amphibians in state of Paraná, southern Brazil

2018

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.

“…Currently, the species is known to occur in the Brazilian states of Bahia (Mercadal 1986, Zaidan andLeite 2012), Paraíba (Vieira et al 2006a), Rio Grande do Norte (Vieira et al 2006a, Jorge et al 2012, Pernambuco (Santos et al 2009), Piauí (Roberto et al 2013), Minas Gerais (Maciel et al 2013), and Sergipe (Santana et al 2014; Figure 1). Ceratophrys joazeirensis is poorly known because of its ecology, cryptic coloration, relatively rarity in nature, and activity that is limited to the rainy season.…”

On the natural history of the Caatinga Horned Frog, Ceratophrys joazeirensis (Anura: Ceratrophryidae), a poorly known species of northeastern Brazil. Data on reproduction, sexual dimorphism, and the diet of Ceratophrys joazeirensis, the only species of the genus that occurs in the Brazilian semiarid Caatinga Biome, are presented. Anurans were observed and collected in Santa Maria Municipality, state of Rio Grande do Norte in northeastern Brazil. Fieldwork was conducted at night either after or during rains throughout the rainy season in 2010-2013. Searches were conducted near places where males were calling, usually around the perimeters of bodies of water. Reproduction is explosive in the of 2011-2013. However, in 2010, neither calling males nor active females were found, even after rainy days. Although males call in temporary and permanent ponds, most males call in the marginal vegetation of temporary ponds. Females C. joazeirensis larger than males. The average clutch size is 2555.0 ± 1551.1 eggs; clutch size is not important prey categories in the diet of C. joazeirensis are anurans, followed by coleopterans and plant material. The apparent importance of anurans in the diet probably is related to the number of anuran species that co-occur with C. joazeirensis and the voracious feeding behavior of ceratophryids.
