1. Comportamento territorial, vocalização e biologia reprodutiva de Allobates olfersioides (Anura: Aromobatidae)
RESUMO Em anfíbios a territorialidade, o cortejo elaborado e outras formas de comportamento, parecem estar mais associados a espécies que exibem o padrão de reprodução prolongado. A vocalização é um importante aspecto biológico relacionado à reprodução e ao comportamento social dos anuros. Este é o primeiro estudo com comportamento e vocalizaç�

2. Anuran species in a remnant of the Atlantic rainforest in an urban area
Abstract Forest fragments in urban areas have many habitat resources that frogs use for refuge, reproduction and growth. Knowledge of an anuran assembly is the first step towards understanding the importance of these forest fragments in areas highly threatened by anthropogenic actions. We sampled anurans during the day and night from November 2012 to August

3. Species composition and reproductive modes of anurans from a transitional Amazonian forest, Brazil
The aim of the present study was to describe the species composition and reproductive modes of an anuran community from a transition area between the Amazonia and Cerrado biomes. Data were collected in habitats exhibiting different degrees of anthropogenic degradation. The community (35 species) identified during the present study presented a larger number o

4. Comportamento territorial de Hylodes nasus em um riacho na Floresta da Tijuca, Rio de Janeiro. / Territorial behavior of Hylodes nasus in a stream at Floresta da Tijuca, Rio de Janeiro
The territorial behavior is exhibited by animals that compete for resources within a specific defended area. By excluding potential competitors in this area through aggressive behavior, territorialist individuals ensure priority access to essential resources for their survival and reproduction. In anuran amphibians, territoriality has been mainly related to

5. Aspectos da ecologia de Ischnocnema Parva (Girard, 1853) (Brachycephalidae) em uma área de Mata Atlântica da Serra da Concórdia, RJ. / Ecology of Ischnocnema parva (Brachycephalidae) at the Atlantic Rainforest of Serra da Concórdia, RJ
O gênero Ischnocnema, família Brachycephalidae, inclui várias espécies que são importantes constituintes das comunidades de anuros do folhiço das florestas da Mata Atlântica do Brasil. Ischnocnema parva é endêmica do bioma Mata Atlântica e possui distribuição geográfica restrita às florestas da região sudeste. Atualmente, poucas são as inform

6. Variações em caracteres morfológicos e ecológicos em populações de Bothrops jararaca (Serpentes: Viperidae) no estado de São Paulo / Variations in morphological and ecological characters of Bothrops jararaca populations (Serpentes: Viperidae) in São Paulo State
Widely distributed snakes exposed to different conditions of temperature and precipitation throughout their distributions may present geographic variation in morphological and ecological characters (e.g. diet and reproduction). In this study, I investigate whether Bothrops jararaca populations from coastal and adjacent mid-elevation sites of the Serra do Mar

7. CONTRIBUIÇÃO AO ESTUDO DA BIOLOGIA DOS TRIPANOSSOMAS DE ANUROS NEOTROPICAIS
The present research had as its main goal, checking the infection through trypanosomes in Anuran around Mato Grosso and Rio de Janeiro States. For that purpose 20 species from Bufonidae, Microhylidae, Hylidae and Leptodactylidae families were collected during the fauna rescue activities at Guapore Power Station the border of Vale de São Domingos, Pontes Lac

8. Cerrado assemblages of reptiles and amphibians along the drainage of Rio Tocantins and the impact of hydroelectric power plants on their conservation / Assembléias de répteis e anfíbios do Cerrado ao longo da bacia do rio Tocantins e o impacto do aproveitamento hidrelétrico da região na sua conservação
The Cerrado herpetofauna was studied along the basin of the Tocantins river using three distinct and complementary approaches. First, a fast sampling scheme, covering all the studied area, was conducted in 11 sites between the Central Plateau, in the state of Goiás, and the northern portion of the Tocantins depression, at the border of the states of Tocanti

9. Ecologia reprodutiva de uma comunidade de anfibios Anuros na serra do Japi, sudeste do Brasil
An anuran community was studied at the Serra do Japi, municipality of Jundiai (ca. 23Q13 S; 46°48 W, 870 m above sea leveI), São Paulo State, southeastern Brazil. The following environments were studied: reservoir, rapid rivulets, temporary ponds, and the surrounding forest. The study was carried out between March 1988 and February 1989, and field data wer

10. Distribuição sazonal e espacial de girinos em corpos d agua na região de Botucatu, São Paulo (Amphibia, Anura)
Abstract: In the present work twenty one anuran species (tadpoles and adults) were studied from twenty different pools in the region of Botucatu ? São Paulo, from february 1984 to march 1985. The purpose of this work was to ascertain the mode of resource partitioning by tadpoles of several species, concerning: distribution of tadpoles and adults emitting vo

11. The role of nocturnal vision in mate choice: females prefer conspicuous males in the European tree frog (Hyla arborea)
Nocturnal frog species rely extensively on vocalization for reproduction. But recent studies provide evidence for an important, though long overlooked, role of visual communication. In many species, calling males exhibit a conspicuous pulsing vocal sac, a signal bearing visually important dynamic components. Here, we investigate female preference for male vo
