“…A recent review of the taxonomy and distribution of the salamanders of the genus Bolitoglossa in Brazil enabled the recognition of five species within the genus for the Brazilian Amazon (Brcko et al 2013). Of these, Bolitoglossa caldwellae was described for the municipalities of Cruzeiro do Sul, Marechal Thaumaturgo and Porto Walter, Acre State.…”

“…Although it represents the third highest richness of anurans among the Brazilian states (Toledo & Batista 2012), this biodiversity can be considered underestimated in number and complexity when considering the political limits, given the existence of a large number of cryptic species (Funk et al 2011), several sampling gaps due to the concentration of researches in a few areas (Azevedo-Ramos & Galatti 2002) and the scarcity of studies that use appropriate methods for the record of amphibians belonging to different niches (Lynch, 2005). However , the number of recorded species has increased rapidly, with frequent descriptions of new species of anurans (e.g., Nunes et al 2012, Simões et al 2013, Peloso et al 2014, Rojas et al 2014) and amphibians of the orders Gymnophiona (Maciel & Hoogmoed 2011) and Caudata (Brcko et al 2013) for the biome.…”

Despite the historical knowledge on amphibians of the Purus River basin, basic information on assemblages is fragmented, with gaps in knowledge existing at various scales, which limits conservation strategies. This study provides information on the composition, richness and abundance of the amphibian fauna in varzea environments and floating meadows of the oxbow lakes of the Middle Purus River between the Boca do Acre and Pauiní municipalities, Amazonas, Brazil. We sampled six oxbow lakes using forty-seven 200-meter transects, distributed among the ''floating meadows,'' ''high varzea'' and ''low varzea,'' from April to January 2014. We recorded 59 species, with the family Hylidae being predominant. This amphibian fauna represents approximately 19% of the species known for the Amazon, 28% for Amazonas State and 45% of the species recorded so far in the Purus River, increasing the richness of the basin to 132 species. Eight species were considered rare, and 29 are endemic to the Amazon. This study adds to the knowledge on the amphibian species of the Amazonian lowlands, including the expansion of known distributions, as well as increases the knowledge of several species that are locally rare, endemic and/or that are data deficient regarding distribution and ecology. Keywords: Amazon, floodplain, flood pulse, diversity, conservation. Resumo: Apesar do histó rico conhecimento sobre anfíbios ao longo da bacia do rio Purus, informac¸õ es bá sicas sobre as taxocenoses encontram-se fragmentadas, formando lacunas no conhecimento do grupo em diversas escalas e restringindo estratégias de conservac¸ã o. Este estudo apresenta a composic¸ão, a riqueza e a abundâ ncia da fauna de anfíbios em ambientes de vá rzea e bancos de macró fitas de lagos de meandro do médio Rio Purus, entre os municípios de Boca do Acre e Pauiní, Amazonas, Brasil. Conduzimos amostragens em seis lagos de meandro, através de 47 transectos de 200 metros, distribuídos entre os ambientes ''banco de macró fitas'', ''vá rzea alta'' e ''vá rzea baixa'', entre abril de 2013 e janeiro de 2014. Registramos 59 espécies, com predomínio de espécies da família Hylidae. Essa fauna de anfíbios representa aproximadamente 19% das espécies conhecidas para a Amazô nia, 28% para o estado do Amazonas e 45% do registrado até o momento para o rio Purus, elevando a riqueza da bacia para 132 espécies. Oito espécies foram consideradas raras e 29 sã o endêmicas da Amazô nia. Este estudo contribui para o conhecimento das espécies de anfíbios das terras baixas na Amazô nia, incluindo a ampliac¸ão da distribuic¸ã o e aumento do conhecimento sobre diversas espécies localmente raras, endêmicas e/ou com deficiência de dados sobre distribuic¸ã o e ecologia. Palavras-chave: Amazônia, planície de inundac¸ão, pulso de inundac¸ão, diversidade, conservac¸ão.

“…Furthermore, based on the large genetic divergences found among the Brazilian salamander samples studied by them, these authors also suggest the existence of a species complex under this taxon name, stating the need of more detailed studies. Recently, Brcko et al (2013) analyzed the external morphological characteristics of 278 Bolitoglossa specimens and confirmed the presence of a species complex in the Brazilian Amazon, suggesting an increase of species from one to five ( B. caldwellae sp. nov., B. madeira sp.…”

“…Its 124 assigned species represent around 20% of the living caudate species (Sessions, 2008; Rovito et al , 2012; Frost, 2013; Brcko et al , 2013). Widespread over the American tropics, these salamanders are found from northeastern Mexico to the South American Rainforest, and Middle America is the most species-rich region (Parra-Olea et al , 2004).…”

Cytogenetics of the Brazilian Bolitoglossa paraensis (Unterstein, 1930) salamanders (Caudata, Plethodontidae)

et al. 2014

Plethodontid salamanders of genus Bolitoglossa constitute the largest and most diverse group of salamanders, including around 20% of living caudate species. Recent studies have indicated the occurrence of five recognized species in the Brazilian Amazon Rainforest. We present here the first cytogenetic data of a Brazilian salamander, which may prove to be a useful by contribution to the cytotaxonomy of the genus. Specimens were collected near the “type” locality (Utinga, Belém, PA, Brazil). Chromosomal preparations from duodenal epithelial cells and testes were subjected to Giemsa staining, C-banding and DAPI/CMA3 fluorochrome staining. All specimens showed a karyotype with 13 bi-armed chromosome pairs (2n = 26). Nucleolar Organizer Regions, evidenced by CMA3, were located distally on the long arm of pair 7 (7q). DAPI+ heterochromatin was predominantly centromeric, with some small pericentromeric bands. Although the C-banding patterns of other Bolitoglossa species are so far unknown, cytogenetic studies conducted in other Plethodontid salamanders have demonstrated that pericentromeric heterochromatin is a useful cytological marker for identifying interspecific homeologies. Species diversification is usually accompanied by chromosomal changes. Therefore, the cytogenetic characterization of Bolitoglossa populations from the middle and western Brazilian Amazon Basin could identify differences which may lead to the identification of new species.

The region of Volta Grande do Xingu River, in the state of Pará, presents several kinds of land use ranging from extensive cattle farming to agroforestry, and deforestation. Currently, the Belo Monte Hydroelectric Power Plant affects the region. We present a checklist of amphibians and reptiles of the region and discuss information regarding the spatial distribution of the assemblies based on results of Environmental Programmes conducted in the area. We listed 109 amphibian (Anura, Caudata, and Gymnophiona) and 150 reptile (Squamata, Testudines, and Crocodylia) species. The regional species richness is still considered underestimated, considering the taxonomic uncertainty, complexity and cryptic diversity of various species, as observed in other regions of the Amazon biome. Efforts for scientific collection and studies related to integrative taxonomy are needed to elucidate uncertainties and increase levels of knowledge of the local diversity.Keywords: herpetofauna, monitoring, Amazonia, Belo Monte. Contribuições para o conhecimento de anfíbios e répteis da Volta Grande do Xingu, norte do Brasil ResumoA região da Volta Grande no Rio Xingu, localizada no estado do Pará, apresenta várias frentes de exploração que vão desde a criação animal até área de cultivo, resultando no desmatamento de fragmentos florestais. Atualmente a região está sendo impactada pela implantação da Usina Hidrelétrica de Belo Monte. A partir de dados obtidos através dos Programas de Monitoramento Ambiental realizados na área de influência da UHE Belo Monte, apresentamos uma listagem das espécies de anfíbios e répteis, com comentários sobre a distribuição espacial das assembleias. Foram catalogados 109 espécies de anfíbios (Anura, Caudata e Gymnophiona) e 150 de répteis (Squamata, Testudines e Crocodylia). Considerando as incertezas taxonômicas, a complexidade e a diversidade críptica de várias espécies, a riqueza regional ainda continua subestimada, assim como observado em outras regiões da Amazônia. Esforços direcionados ao aproveitamento científico e estudos que contemplem a taxonomia integrativa são necessários para elucidar as incertezas e aumentar o nível de conhecimento sobre a diversidade da região.Palavras-chave: herpetofauna, monitoramento, Amazônia, Belo Monte.
