“…A diversidade de espécies encontrada está dentro do esperado para localidades do Cerrado, onde a riqueza de anfíbios anuros e de répteis é heterogênea, com valores variando entre 23 e 71 espécies de anfíbios (Diniz-Filho et al, 2006) e entre 15 a mais de 70 espécies de répteis Squamata (Costa et al, 2007). Apesar de superar a riqueza de 25 espécies de anfíbios obtida por Kopp et al (2010) para o Parque Nacional das Emas, o número de espécies de anfíbios encontrados neste estudo é inferior ao conhecido para outras localidades do bioma (Vaz-Silva et al, 2007;Oda et al, 2009;Valdujo et al, 2009b;Morais et al, 2012;Nomura et al, 2012;Melo et al, 2013). Assim como verificado para anfíbios, a riqueza de 33 espécies de répteis também é inferior ao registrado em alguns estudos (Costa et al, 2007;Vaz-Silva et al, 2007;Nogueira et al, 2009;Silva Jr. et al, 2009;Nogueira et al, 2011) e superior a outros (Souza et al, 2010;Santos et al, 2011;Morais et al, 2012).…”

ResumoGrande parte da biodiversidade de anfíbios e répteis conhecida para o Brasil está representada nas regiões sob domínio do Cerrado, que tem sofrido intensa ação antrópica, causando elevada perda de espécies. Estratégias para conservar a diversidade biológica necessitam de estudos com ênfase em sua quantificação e distribuição em pequena e larga escala. Neste trabalho, caracteriza-se a herpetofauna da porção média do rio Aporé, localizada nos Estados de Goiás e Mato Grosso do Sul, Brasil, através de um inventário realizado entre outubro de 2009 e julho de 2011. Registramos 28 espécies de anfíbios, distribuídas em seis famílias, e 33 espécies de répteis, distribuídas em 14 famílias. A herpetofauna na região do médio rio Aporé apresentou riqueza correspondente a 13,4% das espécies de anfíbios e 14% das espécies de répteis conhecidas para o Cerrado, sendo endêmicas duas espécies de anfíbios e cinco espécies de répteis. A distribuição da riqueza e abundância de anfíbios e répteis não foi homogênea entre os ambientes amostrados e o elevado grau de heterogeneidade espacial provavelmente influenciou as diferenças de diversidade entre os ambientes. Similarmente a outras áreas de Cerrado, a herpetofauna do médio rio Aporé possui diversas espécies endêmicas, especialistas de hábitat e com poucos registros em outros biomas.Palavras-chave: Cerrado, hotspot, inventário, herpetofauna, diversidade. AbstractMuch of the biodiversity of amphibians and reptiles known to Brazil is represented in the regions under the domain of the Cerrado, which has suffered intense anthropogenic activities and, thus, threatened by loss of species. Strategies for conserving biological diversity require studies with emphasis on its quantification and distribution both in small and in large scale. In this paper, we characterize the herpetofauna along the middle portion of the Aporé river, localized in the States of Goiás and Mato Grosso do Sul, Brazil, through an inventory carried out between October 2008 and July 2011. We recorded 28 species of amphibians, represented by six families and 33 species of reptiles, distributed in 14 families. The herpetofauna sampled in the mid river Aporé has a richness corresponding to 13.4% of amphibians and 14% of reptile species known to biome, being endemics two species of amphibians and five reptiles. The distribution of richness and abundance of amphibians and reptiles was not homogenous among the sampled sites and the high degree of spatial heterogeneity probably influenced the difference in diversity between environments. Similarly to other areas in Cerrado, the herpetofauna along the mid river Aporé has many endemic species, habitat specialists and with few records in other biomes.

“…On the other hand, increasing the sampled areas the number of species tends to increase, as observed by Brasileiro et al (2008) and Melo et al (2013), which recorded 33 and 36 species, respectively, in studies carried out in various sampling sites in the states of Maranhão and Goiás. Santos et al (2014) registered 40 species of amphibians in 17 municipalities of the Piracanjuba and Peixe rivers basins in the southeast of Goiás.…”

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

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. Registramos 31 espécies de anuros, pertencentes a cinco famílias (números de espécies entre parênteses): Leptodactylidae (14), Hylidae (12), Bufonidae (3), Microhylidae (1)

Local niche-based processes and dispersal are important determinants of assemblage composition and species diversity. However, there is no consensus about the relative importance of niche and spatial processes to explain the distribution of anuran species in tropical systems. In our study, we analyzed the niche and neutral effects on anuran assemblages and found that biotic interactions were a predictor of assemblage structure. The Eltonian concept of niche was the best predictor for the structure of aquatic-breeding anuran assemblages, as species tended to co-occur more often than would be expected by chance. We suggest that the lack of environmental effect could be explained by differences in the pattern of movement between arboreal and non-arboreal anurans. Once there is a reduction in the number of arboreal anurans in open areas, the importance of habitat heterogeneity to explain assemblage composition should decrease. The lack of correlation between the spatial component in our model and species composition is evidence that spatial processes, such as migration, did not play a major role in structuring local assemblages. Anurans are generally assumed as having poor dispersal ability, yet this assumption is not true for all anuran species. We suggest that future studies should include key behavioral traits, such as site fidelity and homing behavior, as these traits can represent the dispersal abilities of anurans and dispersal ability seems to be important when we try to predict patterns of anuran distribution.
