We studied the herpetofaunal community from Atlantic forest of Morro São João, in Rio de Janeiro State, Brazil, and present data on species composition, richness, relative abundance densities. combined three sampling methods: plot sampling, visual encounter surveys pit-fall traps. recorded sixteen amphibians nine reptiles. The estimated densities (based results sampling) were 4.5 ind/100 m2 for 0.8 m² lizards, overall density (amphibians lizards) was 5.3 m². For amphibians, Eleutherodactylus...

Brachycephalus didactylus, a leaf litter frog endemic to the Brazilian Atlantic rain forest, is considered world's smallest tetrapod. Currently, there little information about ecology of this species. In study, we estimated population density and analyzed diet, sexual dimorphism, some reproductive aspects two populations B. didactylus in Rio de Janeiro State, Brazil. The was 4.0 1.2 ind/100m2, suggesting that not locally rare However, collecting these frogs may be difficult because their...

The anurofauna inhabiting higher montane Atlantic forest areas in southeastern Brazil, which often attain heights of more than 2000 m, is still insufficiently known. In this study, we present data on anuran species composition and abundances two high-altitude (i.e. > 1000 m) sites within the Parque Estadual dos Três Picos (PETP), state Rio de Janeiro. Field surveys were done at altitudes between 1100 1900 m above sea level. We recorded 35 during our adding 22 records to set previously known...

The diet composition of lizards a given species may vary among different populations. feeding ecology the tropidurid lizard Tropidurus torquatus was studied in 10 coastal areas Brazil order to detect what extent varies along its geographic range. A non-metric multidimensional scaling technique revealed three groups localities according composition: one characterized by relatively high consumption Isoptera, proportion plant matter, and which there great importance Formicidae. We found weak...

We analyzed the feeding ecology of four Thoropa miliaris (Anura, Cycloramphidae) populations from Atlantic Rain Forest in Brazil. The diet was composed mostly invertebrates, especially ants, beetles, grasshoppers, caterpillars, and spiders. Plant consumption considered incidental because its low frequency. Ants were most frequent (range 70–100%) numerous 54.9–63.8%) dietary items. In terms volume, ants principal item at two localities (26.1% 47.6%), being also important items for other areas...

Data on species composition, richness, and density are presented for the leaf litter frog assemblage of an area Atlantic Rainforest at Serra dos Órgãos mountain range, in state Rio de Janeiro, southeastern Brazil. Three sampling methods were used: plot sampling, visual encounter surveys, pitfall traps. The local frogs was composed 16 species, with direct-developing Euparkerella brasiliensis (Parker, 1926), being most abundant. estimated based 17.1 ind/100 m² overall mass 684.2 g/ha. present...

Species inventories are useful tools to improve conservation strategies, especially in highly threatened biomes such as the Brazilian Atlantic Forest. Here we present a species list of amphibians and reptiles for Reserva Ecológica de Guapiaçu (REGUA), forest reserve located central portion Rio Janeiro state, Brazil. The results from an extensive sampling effort that lasted ten years. A total 73 amphibian (of which endemic state) 37 reptile was recorded area. Five presently categorized by...

Despite a recent increase of information on leaf litter frog communities from Atlantic rainforests, few studies have analyzed the relationship between environmental parameters and community structure these animals. We effects some factors at an Rainforest area in southeastern Brazil. Data collection lasted ten consecutive days January 2010, elevations ranging 300 520 m above sea level. established 50 quadrats 5 x forest floor, totaling 1,250 m² sampled area, recorded mean leaf-litter depth...

Abstract Altitudinal patterns in species richness vary among taxa and are shaped by the intrinsic traits of different organisms their response to environmental variables. We evaluated relationship between anuran elevation along local regional altitudinal gradients within Brazilian Atlantic Forest based on data from fieldwork (local dataset; 100–1900 m a.s.l.) compiled secondary information (regional 0–2300 a.s.l.). also tested whether frog distribution were consistent with predictions...

Ischnocnema (Brachycephalidae) includes many species that are important members of the leaf litter frog communities in Atlantic Rainforest Brazil. parva (Girard, 1853) is endemic to biome and restricted forests southeastern Currently, available information about ecology I. scarce. We studied diet, habitat use, reproduction density an area at Concórdia mountain range, Rio de Janeiro. Individuals were captured April 2005 using different sampling methods: time constrained search (transects),...

Insular lizards usually consume a large proportion of plant material compared to mainland ones, which is frequently attributed low prey availability on islands. In the present study, we analyze diets six populations (three insular and three continental) omnivorous lizard Tropidurus torquatus eastern Brazilian coast, assess extent continental differ in feeding habits, especially consumption material. The degree varied greatly among areas, with volumetric food ranging from 5% 67%, but there...

In this study we analyzed the diet of gymnophthalmid lizard Ecpleopus gaudichaudii Duméril & Bibron, 1839, a typical inhabitant forest-floor leaf litter, in an Atlantic Forest area state Rio de Janeiro, southeastern Brazil. The 26 individuals sampled during had mean snout-vent length (SVL) 36.2 ± 4.2 mm and jaw width (JW) 4.1 0.5 mm. We did not find differences SVL between males females, though sexes differed JW when effect body size was factored out, with females presenting higher values....

The Brazilian Atlantic Forest is one of the richest and most threatened biomes on Earth. In state Rio de Janeiro it presently reduced to less than 20% its original extension, faunal lists are needed for several areas. Here we present a species list amphibians reptiles Estação Ecológica Estadual do Paraíso (EEEP), forest reserve located in central portion state. based both primary (gathered during short-term survey by authors) secondary data (obtained from local reference collection). A total...

A new species of the rare anuran genus Holoaden is described from a montane rainforest area in Rio de Janeiro State, southeastern Brazil. The characterized by its large body size, head, moderately bulging dorsal glands, limbs long and slender, deeply dark coloration, ventral surface with light abdominal blotch variable size. expands range 200 km eastward

Brachycephalus garbeanus is an aposematic toadlet, endemic to the Atlantic Forest in mountains of state Rio de Janeiro, southeastern Brazil. Information regarding ecology species this genus scarce, with no information on most species, including B. garbeanus. We provide ecological about garbeanus, particular microhabitat use, sexual dimorphism body size, and feeding habits.

We conducted active searches (460 hours) between January 2013 December 2015. identified taxa endemic either Atlantic Forest or Janeiro state, verified...

The genus Hylodes Fitzinger, 1826 is restricted to eastern Brazil, occurring from the states of Espírito Santo Rio Grande do Sul (Lingnau et al. 2008, Frost 2010). Except for otavioi, which inhabits riparian forests in rocky fields (“campos rupestres”) habitats within Cerrado domain Minas Gerais State (Sazima & Bokermann 1982), all other species are endemic Atlantic Rainforest 2008). currently comprises 24 (Frost 2010) small medium-sized diurnal frogs that live associated lotic streams...

Toadlets of the genus Brachycephalus are endemic to Brazilian Atlantic Rainforest, where they inhabit forest floor leaf litter. These miniaturized frogs commonly known as flea-toads or pumpkin toadlets depending on their phenotypic characteristics. Herein, we describe a new species from montane forests (970–1200 m a.s.l.) in Serra dos Órgãos mountain range, state Rio de Janeiro, southeastern Brazil.
