“…The finding of a large number of species of the families Hylidae and Leptodactylidae was similar to the results of other studies and follows the pattern found in neotropical environments (Segalla et al 2016), including the Brazilian Amazon (Azevedo-Ramos and Galatti 2002, Neckel-Oliveira et al 2013, Ramalho et al 2016). In addition, three species of anurans (Pristimantis cf. ockendeni, Hyalinobatrachium iaspidiense and Scinax garbei ) are new records in the Amapá state (Silva e Silva and Costa-Campos 2014, Silva e Silva et al 2015, Silva e Silva and Costa-Campos 2016), evidence the incipience of knowledge in the regional context due to the lack of sampling.…”

In this study, the first survey of anuran species in the Cancão Municipal Natural Park is presented, a protected area of approximately 370 hectares of Amazonian forest located in the northwest center region of the state of Amapá, Brazil. The work was performed during the dry and rainy season, through active visual and auditory survey, totaling 216 man hours of sampling effort. Forty-nine species of anuran amphibians were recorded in the Cancão Municipal Natural Park, including three new records: Hyalinobatrachium iaspidiense, Pristimantis cf. ockendeni, and Scinax garbei. Three species, Hyalinobatrachium iaspidiense, Ameerega pulchripecta, and Anomaloglossus baeobatrachus, are listed as Data Deficient and one is listed as Vulnerable (Atelopus hoogmoedi) according red lists of IUCN. The rarefaction curve cumulative species did not reach an asymptote, indicating that site has potential for species that have not yet been recorded. Nine species were represented by only one individual and were considered rare in the studied environments, eight species were defined as common, and the 32 remaining species were classified as having intermediary abundance. Our data indicated that Cancão Municipal Natural Park contains a considerable portion of the anurans species richness of Amapá state, turn the area into a place of great importance for the conservation of the anurans of the Eastern Amazon.

“…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.

“…High heterogeneity of macrophytes is expected in lentic environments (Moura J unior et al 2015) as oxbow lakes (Mormul et al 2013). The habitat heterogeneity formed by v arzeas and macrophyte rafts maintain the biodiversity (Wittmann et al 2006, von May & Donnelly 2009, Waldez et al 2013, Upton et al 2014, Ramalho et al 2016; however, it is poorly known in terms of beta diversity.…”

Beta diversity can provide insights into the processes that regulate communities subjected to frequent disturbances, such as flood pulses, which control biodiversity in floodplains. However, little is known about which processes structure beta diversity of amphibians in floodplains. Here, we tested the influence of flood pulses on the richness, composition, and beta diversity of amphibians in Amazonian floodplain environments. We also evaluated indicator species for each environment. We established linear transects in three environments: low várzea, high várzea, and macrophyte rafts. Species richness decreased and beta diversity increased according to the susceptibility of habitats to flood pulses. Indicator species differed among environments according to forest succession promoted by the flood pulse. The decrease in species richness between high and low várzea is due to non‐random extinctions. The higher rates of species turnover between várzeas and macrophyte rafts are driven by the colonization of species adapted to open areas. Our results highlight that the maintenance of complex environments is needed to protect biodiversity in floodplains.
