“…This suggests that L. catesbeianus may not have become an invasive species in the area and is possibly confined to perianthropic environments. The status of introduced American bullfrog populations in Brazil and their actual impact on natural ecosystems are currently not well known, despite this species having been reported in the wild from numerous localities in Brazil (Giovanelli et al 2008, Both et al 2011.…”

Species inventories are useful tools to improve conservation strategies, especially in highly threatened biomes such as the Brazilian Atlantic Forest. Here we present a species list of amphibians and reptiles for the Reserva Ecoló gica de Guapiaçu (REGUA), a forest reserve located in the central portion of Rio de Janeiro state, Brazil. The list results from an extensive sampling effort that lasted ten years. A total of 73 amphibian (of which ten are endemic to the state) and 37 reptile species was recorded from the area. Five amphibian species are presently categorized by the IUCN as ''data-deficient'', two as ''near threatened'' and one as ''endangered'', whereas one reptile species is categorized as ''vulnerable''. Our results showed that REGUA harbors about one-third of the herpetofauna species presently known to occur in state of Rio de Janeiro, adding more information to previously published lists of amphibians and reptiles from localities within the Serra dos Ó rgã os region, and highlighting the importance of this area for conservation of amphibians and reptiles of the Atlantic Forest.

“…The most extensive biological invasions of the North American bullfrog into South America are in Brazil and Argentina, with feral populations identified over a large extent of their territories (24,25,16). Until now, the only other work that has looked into Bd infection of feral bullfrogs in central Argentina did not detect chytrid (25 specimens examined histologically) (17).…”

“…The anuran Lithobates catesbeianus, originally from North America, is commercially farmed as a food source. Due to negligence in their containment, they commonly end up escaping captivity and settling up populations in natural environments, where they may cause problems to the native communities (Both et al, 2011;Silva et al, 2011). The locality in which this species was collected constitutes a new register for the state of Minas Gerais.…”

ABSTRACT. Diversity analysis by partition is an approach employed in order to understand how communities spatially structure themselves and the factors that operate in the generation and maintenance of distribution patterns. We examined the spatial structure of species diversity of four taxonomic groups, with diff erent dispersal abilities, in 16 forest fragments in the southern region of the state of Minas Gerais, Brazil. Specifi cally, we tested: i) if the similarity in species composition would be negatively related to geographical distance between the 16 fragments; and ii) if the beta diversity of the diff erent groups could be negatively related to their dispersal abilities. Alpha diversity and the compositional similarity between localities were both low. Beta diversity was not correlated with distance for any of the groups. Primates, followed by birds, showed a higher tendency of forming similarity groupings, although in a manner that was independent from distance between fragments, as well as showed the lowest beta diversity relative values. Spermatophytes and amphibians did not defi ne groupings and presented the highest values of beta diversity. We interpreted such results as indications that the groups with higher dispersal ability (primates and birds) tend to reach, on average, farther localities and, therefore, to defi ne more similar groupings (low beta diversity). The groups with lower dispersal ability (spermatophytes and amphibians) showed the opposite tendency. Although most of the species were restricted to few localities, contributing to the low similarity, beta and gamma diversity values showed the extent which the localities are, respectively, diff erent and complementary to each other in terms of species composition. Such features reinforce and justify future conservation initiatives, both in local and regional levels.KEYWORDS. Complementarity, dispersal ability, vertebrates, spermatophytes, Atlantic Forest.RESUMO. Grupos taxonômicos com menor capacidade de dispersão podem apresentar maior diversidade beta. A análise da diversidade por partição é uma abordagem empregada para tentar compreender como as comunidades se estruturam espacialmente e os fatores que operam na geração e manutenção dos padrões de distribuição das espécies. Nós examinamos a estrutura espacial da diversidade de espécies referente a quatro grupos taxonômicos com diferentes capacidades de dispersão, em 16 fragmentos fl orestais localizados no sul do Estado de Minas Gerais, Brasil. Especifi camente, testamos: i) se a similaridade na composição de espécies estaria relacionada negativamente com a distância geográfi ca entre os fragmentos e ii) se a diversidade beta apresentada por cada grupo poderia ser negativamente relacionada com as respectivas capacidades de dispersão. Tanto a diversidade alfa quanto a similaridade composicional entre as localidades foram baixas. A diversidade beta não esteve correlacionada com a distância para nenhum dos grupos. Os primatas, seguidos das aves, apresentaram maior tendência em formar agr...
