“…Some examples of doubtful identification are Pristimantis aff. conspicillatus, P. fenestratus, Leptodactylus marmoratus species group, Allobates marchesianus species group, Dendropsophus microcephalus species group, and several other species with wide distributions in Amazonia (Peloso 2010). Further considering morphological and molecular data might reveal complexes of cryptic species studies within these groups and bring new insights into their taxonomic limits.…”

The region of Carajás in the southeast of the state of Pará, Brazil, harbors five reserves, with various managing categories, distributed throughout five municipalities. A list of amphibians known to occur in this region was compiled using information on the specimens deposited in the herpetological collection of the Goeldi Museum, collected during the past four decades (1969 - 2010). According to the available metadata, the species were tabulated in three environments: ombrophylous forest (rainforest), metalophic savanna (MS) and anthropic areas (AA - secondary forest - disturbed areas), resulting in 13 families and 71 species (66 anurans and 5 Gymnophiona). Ombrophylous forest has 50 species, anthropic areas has 49 species, while metalophic savanna has 38 species of anuran.

“…The difficulty in reaching precise identifications of several taxa that probably represent complexes of multiple species is a common problem involving Amazonian species (Peloso 2010). This issue prevents us from drawing explicit comparisons between different areas and conclusions on the actual distribution of some amphibian species.…”

“…For aquatic chelonians, for example, special collection techniques, such as funnel traps and other baited aquatic traps (not used in this survey) may be required. The sampling of caecilians (Gymnophiona) is also quite complicated-they are usually found by chance, as they may exhibit partially or completely aquatic or fossorial habits (Ávila-Pires et al 2010;Peloso 2010). Localized efforts, such as baited trapping for aquatic species, and digging for fossorial species can yield large number of individuals of this taxa (unpubl.…”

“…Azevedo-Ramos and Galatti (2002) estimated that, for Amazonian amphibians, the number of undetermined taxa (those unidentified to species level) might vary from 2-39% of the total of sampled species in a given area. Undetermined taxa may be a consequence of one or several combined factors, including: presence of unnamed species in the sample, lack of sufficient taxonomic knowledge about a given group (e.g., species complexes), insufficient material collected (e.g., if only juveniles or larvae are collected) (Caldwell 1996;AzevedoRamos and Galatti 2002;Peloso 2010).…”

“…Information on the composition and structure of populations of amphibians and reptiles in Amazonia is scarce and usually concentrated close to areas of higher human occupation or with easy access by roads or rivers (e.g., Azevedo-Ramos and Galatti 2002;Vogt et al 2007). In consequence, and due to the vast territory and difficulties with access, many areas in Amazonia are still poorly known in terms of their herpetofauna (Ávila-Pires et al 2010;Peloso 2010).…”

Amphibians and reptiles from Floresta Nacional de Pau-Rosa, Amazonas, Brazil: an important protected area at the heart of Amazonia

2017

Amazonia harbors the largest and most diverse tropical forest in the world, but knowledge about the species diversity of the region is still far from ideal. Given this low level of faunal and floral knowledge, we present an annotated list of the species of amphibians and reptiles found in Floresta Nacional do Pau-Rosa (FNPR), along the Rio Paraconi, municipality of Maués, state of Amazonas, Brazil. Herpetofauna of the FNPR was sampled with pitfall traps, active search and occasional encounters from February 18 to March 28, 2009. A total of 270 specimens were collected, representing 39 species of amphibians and 24 species of reptiles. At least seven of the species collected at FNPR represented, at the time, unnamed taxa (four of which have now been named). The number of taxa collected and the high number of unnamed taxa highlight the importance of this area in terms of biodiversity and as a priority for conservation. We also discuss about the amphibian diversity in Amazonia.
