“…Although this study was conducted strictly in varzea environments and floating meadows, i.e., lowlands, the species richness reported is high compared to most of the studies conducted in the western Amazon (Azevedo-Ramos & Galatti 2002, Souza et al 2008, Franc¸a & Venâncio 2010, Ilha & Dixo 2010, Pantoja & Fraga 2012, Bernarde et al 2013, Prudente et al 2013, corroborating the existence of a diversity gradient where the western plains of the Amazon biome have greater amphibian diversity as a possible effect of the proximity of the highlands of western Amazon and its high patterns of endemism and richness (Heyer 1976, Duellman 1978, 1982, 1988, Azevedo-Ramos & Galatti 2002. This high diversity has also been associated with the occurrence areas of endemism (Silva et al 2005, Waldez et al 2013.…”

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.

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.

“…Todas possuem ampla distribuição no bioma Amazônia, são facilmente encontradas em diversos tipos de hábitats primários e secundários e tendem a ser abundantes nos locais onde ocorrem (Souza et al, 2008;Bernarde et al, 2011;Miranda et al, 2014;Ramalho et al, 2016). Os répteis considerados abundantes neste estudo são representantes da subordem Sauria e mostraram-se associados a bordas de mata e clareiras na vegetação formadas por eventos naturais ou pelo corte seletivo da madeira.…”

ABSTRACT. Local diversity and infl uence of seasonality on amphibians and reptiles assemblages in the Reserva Extrativista Chico Mendes, Acre, Brazil. Despite the high richness of amphibians and reptiles known for the southwestern portion of the Brazilian Amazon, the knowledge of these is punctual and few studies have evaluated the temporal variations in the occurrence and abundance of species. The goals of this study were to present the amphibians and reptiles assemblages in a locality of the Chico Mendes Extractive Reserve, verify which climate variables infl uence the temporal fl uctuations in richness and abundance, and identify the main species of the amphibians and reptiles infl uenced by them. The study area is located in the Seringal Etelvi region, southwestern portion of the Reserve, municipality of Brasiléia, state of Acre. Data collection took place between October 2011 and September 2012, for 48 sampling days, using the methods of searches limited by time and pitfall traps. There were recorded 978 specimens of 31 amphibians and 54 reptiles. Higher richness and abundance of amphibians occurred during the rainy season, with the monthly abundance positively associated with the mean temperature. Only the abundance of reptiles was higher during the rainy period. However, both richness and abundance were positively associated with mean temperature. Four amphibians, Allobates gr. marchesianus, Hamptophryne boliviana (Parker, 1927), Boana geographica (Spix, 1824) and Rhinella marina (Linnaeus, 1758), and two reptiles, Kentropyx pelviceps Cope, 1868 and Norops fuscoauratus (D'Orbigny, 1837), had their monthly abundances positively associated with the mean temperature. The lizard Dactyloa punctata (Daudin, 1802) had the monthly abundance associated with precipitation. It was possible to verify the increase of richness and abundance of amphibians and reptiles during periods when the availability of resources is favorable for many species. Species can react diff erently to climatic variations, whereas others are sensitive to fl uctuations, others seem answer easily or not reduce their abundances in periods theoretically unfavorable.KEYWORDS. Richness, abundance, Southwestern Amazonia, seasonality, temporal variation.RESUMO. Apesar da elevada riqueza de anfíbios e répteis conhecida para a porção Sul-Ocidental da Amazônia brasileira, o conhecimento sobre estes é pontual e poucos estudos avaliaram as variações temporais na ocorrência e abundância das espécies.
