Reproductive behavior of the giant leaf frog Phyllomedusa bicolor (Anura: Hylidae) in the western Amazon

We present here data on the displacement behavior of males, oviposition, and spawn of Phyllomedusa bicolor

Anfíbios do Parque Ambiental Chico Mendes, Rio Branco – Acre, Brasil

http://dx.doi.org/10.5007/2175-7925.2016v29n1p85Acre’s amphibian fauna, although poorly known, is regarded as one of the most diversified. This study aimed to inventory the amphibian fauna in the Environmental Park Chico Mendes, a 57 ha forest fragment, located 7 km far from downtown Rio Branco. The study was conducted between August 2008 and July 2010, by using a visual and auditory search methodology. All tracks and temporary forest pools in the park were inventoried, where the individuals visualized or those using vocalization were registered. A total of 51 taxa were found, distributed into the orders: Anura, with 50 species, and Caudata, with 1 species. Amphibians in the park showed seasonality in reproduction, where the rainiest months were those with the highest number of species in reproductive activity.http://dx.doi.org/10.5007/2175-7925.2016v29n1p85A anfíbio fauna do Acre, apesar de pouco conhecida, é considerada como sendo uma das mais diversas.  O presente estudo teve como objetivo inventariar a fauna de anfíbios do Parque Ambiental Chico Mendes, fragmento florestal de 57 ha, localizado a sete quilômetros do centro da cidade de Rio Branco. O estudo foi realizado entre agosto de 2008 e julho de 2010, com a metodologia de busca visual e auditiva. Todas as trilhas e poças temporárias do parque foram inventariadas, onde registramos os indivíduos em atividade de vocalização ou visualmente. Foi encontrado um total de 51 táxons, distribuídos nas ordens: Anura, com 50 espécies, e Caudata, com 1 espécie. Os anfíbios do Parque mostraram uma sazonalidade quanto à reprodução, sendo os meses mais chuvosos, os com o maior número de espécies em atividade reprodutiva

Reptiles and amphibians of a poorly known region in southwest Amazonia

The Amazon is the largest tropical forest of the world and it is extremely rich in biodiversity. However, some portions of the biome are still poorly known. This work presents an inventory of the herpetofauna of Boca do Acre municipality, a still preserved region located in southwest Amazonas state. The inventory was carried out in two periods, a sampling during the middle of the rainy season and another one at the end of the rains. Diverse survey methods were employed, such as pitfall traps, diurnal and nocturnal visual searches, car searches on the BR 317 highway, and opportunistic registrations. We recorded 56 amphibians and 53 reptiles during the field work. We captured 27 species in pitfall traps, and 38 were found along the BR 317, alive or dead on the road, being snakes principally affected by road-kills. The species accumulation curves did not reach stability, indicating that the inventory was not complete. Our results show the high species richness of this region, its importance for the Amazonian biodiversity, and the urgency of its preservation

Between-year consistency of anuran assemblages in temporary ponds in a deforested area in Western Amazonia

Many studies have shown that forest fragments are depauperate in forest-dependent fauna, and that fragments are invaded by generalist or colonising species. However, rather than representing generalist species, the anurans that occur in disturbed areas around forest remnants may represent a specialist fauna with its own complex interactions rather than generalist species capable of colonising any water bodies available for reproduction. We studied anuran assemblages in 10 temporary ponds around a forest fragment in the State of Acre, Brazil, on the southern border of the Amazon forest, between October and June in 2008, 2009 and 2010. We recorded 24 species in 6 families. Assemblages in ponds were temporally stable, indicating strong deterministic control of assemblage composition. Although they contain fewer species than found in the original forest, these assemblages inhabiting novel ecosystems are highly structured and probably have complex interactions with their biotic and abiotic environments. They are worthy of further study

First record of Rhinella poeppigii (Tschudi, 1845) in Brazil (Anura, Bufonidae)

Rhinella poeppigii, member of the Rhinella marina group, which currently consists of 11 species, inhabits primarily cloud forests in the central Andes of Peru, Ecuador, and Bolivia, reaching lowlands adjacent to the Andes, at elevations of 260–1800 m. This work presents the first record of R. poeppigii in Brazil, from the municipality of Assis Brasil, in the state of Acre. This record extends the distribution of the species 242 km northeast of the nearest record in Explorer’s Inn, Madre de Dios province, Peru
