| In this study we evaluated how anuran species were distributed in riparian habitats along two large rivers. Sampling was carried out between January and March 2012 in the municipality of Cachoeiras de Macacu, state of Rio de Janeiro. We delimited 20 plots along each river, ten in portions inside the forest of the Reserva Ecológica de Guapiaçu (REGUA), and with comparatively greater amount of forest cover, and ten outside REGUA, with comparatively lesser forest cover surrounding the rivers. We recorded 70 individuals from 14 frog species in the Manoel Alexandre River and 63 individuals from 15 frog species in the Guapiaçu River. The most abundant species in both rivers was Cycloramphus brasiliensis (Steindachner, 1864), and it was more abundant in sections... |

| ABSTRACT We investigated the daily activity and thermoregulatory body orientation of Mabuya macrorhyncha (Hoge, 1947), a lizard species that occurs in the Brazilian Atlantic Forest. We conducted this investigation in a sandy coastal dune remnant (“restinga” ecosystem) in Grussaí, state of Rio de Janeiro, Brazil, during the summer. The daily activity cycle of the lizards started around 6:00 am and ended before 7:00 pm. This is longer than observed in other populations of M. macrorhyncha (approximately 7:00 am to 5:00 pm). The activity cycle of the lizards was bimodal, with the first peak between 6:00 and 11:00 am and the second from 2:00 to 7:00 pm. This contrasts with observations on other populations of this species, which revealed an unimodal pattern.... |

| A Reserva Biológica Estadual da Praia do Sul (Ilha Grande, RJ) é um importante remanescente de restinga preservada do Rio de Janeiro. A vegetação das restingas não é homogênea, distribuindo-se em zonas de vegetação, e cada uma delas é caracterizada por sua topografia, fisionomia e florística distintas. Estudamos a comunidade de Bromeliaceae, analisando variações na riqueza, abundância, densidade e freqüência de ocorrência entre quatro zonas de vegetação. Nas quatro zonas, amostramos um total de 150 parcelas de 100 m² cada, onde contabilizamos as espécies e suas abundâncias, e medidas de estrutura da vegetação (altura e DAP das árvores e densidade de árvores e de arbustos do sub-bosque). Testamos diferenças entre zonas na abundância de rosetas e na... |

| Abstract: Data on the composition of local reptile assemblages in several Brazilian ecosystems can still be considered relatively restricted in scope in most cases. In this study, we conducted surveys in the Serra das Torres Natural Monument, located in the municipalities of Atílio Vivacqua, Muqui, and Mimoso do Sul, using the Rapid Assessments method (RAP) during 30 days in the rainy season of 2018. We sampled actively for approximately 1320 hours with a 6-10 person crew, supplemented by 720 hours of passive sampling (30 bucket-days) using pitfall traps with drift fences. We recorded 34 reptile species during our sampling method (2 amphisbaenid, 11 lizards, and 21 snakes) and an occasional encounter, after the end of sampling, that added a chelonian... |

| We analyzed richness, composition and mass of snakes in two sites in the Atlantic forest of Ilha do Cardoso (25º 03' S and 47º 53' W), an island (22,500 ha), Cananéia municipality, São Paulo State, Brazil. A monthly index of arthropod availability (in mm³) was estimated in each site through capture rates in pit-fall traps. Fallen fruits were collected along trails in the study sites (mass of fruit gave an index of fruit availability) and small mammals were sampled in grids with 120 traps which covered the lowland (5.2 ha) and in the slope forests (3.6ha). The abundance and mass of small mammals were standardized for the size of each sampled area (in g.ha-1). To sample snakes we established 20 pit-fall traps in each area and performed monthly transects in... |

| We present data on species composition, relative abundance and estimated densities for leaf-litter anuran amphibians from an Atlantic Forest area within the Parque Estadual do Desengano, in the state of Rio de Janeiro, Brazil, based on results of a short-term survey carried out during the winter at altitudes of 1000-1500 m. Three sampling methods were used: plot sampling, visual encounter surveys (VES; performed during the day, at the twilight, and at night), and pitfall traps. We recorded 13 species, with the direct-developer Ischnocnema parva (Girard, 1853) being the most abundant. Most frogs (ca. 90% of all individuals) sampled by VES were captured during the crepuscular and nocturnal periods. The estimated density of the local leaf-litter frog... |

| ABSTRACT Different spatial and temporal factors can influence the species richness and abundance of leaf anurans that are fundamental for the ecosystem functioning, as they act as predators and integrate the trophic chain as prey of other animals. There are relatively few studies that aimed to understand the spatio-temporal variation and the influence of environmental factors on leaf litter communities. We studied parameters of the anuran community living in the forest leaf litter in the Duas Bocas Biological Reserve (DBBR), Espírito Santo, Brazil. We sought to understand the extent to which richness, abundance, biomass and density varied between two locations with different stages of preservation (primary and secondary forest). In addition, we tested the... |

| Abstract. The amphibian fauna of the state of Rio de Janeiro, in southeatern Brazil, is characterized by high species richness and rates of endemism, and is still insufficiently known. A first list of amphibian species with occurrence in the state was published in 2004 and reported 166 taxa, but since then many new records, descriptions of new taxa, and revalidations and synonymizations of species have consistently improved the knowledge about the state’s amphibian biodiversity. Thus, a review and update of that list was deemed necessary. We herein present an updated and commented list of amphibian species occurring in the state of Rio de Janeiro based on a survey of the literature. We recorded the occurrence of a total of 201 species of amphibians (197... |

| Abstract Ilha Grande is a large continental island (total area of 19,300 ha) situated at the southern coast of the state of Rio de Janeiro, in southeast Brazil, within the Atlantic Forest Biome. Here we provide an update to the previous knowledge of the fauna of amphibians and reptiles occurring in Ilha Grande, based on primary data from our own fieldwork and on secondary data (from institutional collections and from the literature). We report the occurrence at Ilha Grande of a total of 74 species, being 34 amphibians (all of them anurans) and 40 reptiles (27 snakes, 11 lizards, one amphisbaenian and one crocodylian). Our survey added 14 species to the herpetofaunal list of Ilha Grande (three of amphibians and eleven of reptiles) and removed one species... |

| Lizards may benefit from gain of heat from contact with the substrate via conduction. In this study, evidence that the lizards Mabuya agilis (Raddi, 1823) and Mabuya macrorhynclui Hoge, 1946 (Scincidae) inhabiting two restinga habitats in southeastern Brazil (Grussaf, Rio de Janeiro and Praia das Neves, Espfrito Santo), may shift microhabitat preferences along the day, and that such shifts may be related to the use of cacti surfaces as direct sources of heat is presented. For both species, body temperature (Tb) was always significantly correlated (p < 0,05) with air temperature (Ta). Tb was significantly correlated (p < 0,0.5) with substrate temperature (Ts) for M. agilis collected on cacti, but not for specimens collected on the ground. For M.... |

| Muitas espécies de bromélias armazenam água da chuva em seu interior, sendo esta característica resultado da distribuição espiralada de suas folhas, que formam pequenos tanques. O objetivo deste estudo foi avaliar e comparar o volume de água efetivamente armazenado e o volume máximo que pode ser armazenado no tanque de diferentes espécies de bromélias de 13 restingas brasileiras. Em cada restinga, em 100 plots de 100 m² cada, registramos as espécies de bromélias-tanque, os parâmetros morfométricos e o volume efetivo e máximo em 20 indivíduos de cada espécie. Encontramos 32 espécies de bromélias-tanque, para as quais medimos o volume máximo e o volume efetivo de água armazenado. Em 59.007 rosetas, estimamos o volume máximo em 44.388 litros e medimos 17.000... |
