25. Ecology of the bromeligenous frog Phyllodytes luteolus (Anura, Hylidae) from three restinga remnants across Brazil's coast
Neste estudo, analizamos a dieta, dimorfismo sexual e uso de bromélias em três populações do hilídeo Phyllodytes luteolus de habitats de restinga ao longo da costa brasileira. Encontramos 13 categorias de artrópodes em 161 estômagos. Formigas e cupins foram as presas dominantes. O nicho trófico semelhante registrado entre as populações sugere que e

26. How do males of Hypsiboas goianus (Hylidae: Anura) respond to conspecific acoustic stimuli?
ABSTRACT Acoustic communication plays an important role in the social behavior of anurans. Acoustic signals, which can be used in different contexts such as mate attraction and territory defense, may mediate social interactions among individuals. Herein, we used playback experiments to test whether males of Hypsiboas goianus (Lutz, 1968) change their vocal b

27. Seleção de sítio para nidificação de Hypsiboas faber (Anura, Hylidae) no sul do Brasil.
RESUMO Machos de espécies de Hypsiboas Wagler, 1830 constroem ninhos no substrato disponível no entorno de corpos d'água; as fêmeas depositam os ovos no interior destes ninhos durante a reprodução da espécie. Embora estes machos apresentem plasticidade na escolha de sítios para construção dos ninhos, ainda não existem avaliações de preferências

28. The island rule in the Brazilian frog Phyllodytes luteolus (Anura: Hylidae): incipient gigantism?
ABSTRACT The island rule suggests that, when mainland animals are isolated on islands, large animals tend to become smaller, while small animals tend to become larger. A small frog in eastern Brazil, Phyllodytes luteolus (Wied-Neuwied, 1824), is widely distributed in association with bromeliads. At the end of the last glaciation, parts of the mainland became

29. Advertisement and release calls of Phyllomedusa ayeaye (Anura: Hylidae) with comments on the social context of emission
ABSTRACT Male calls play different roles in anuran social organization, such as spacing, territoriality and female attraction. However, calls and associated behaviors remain poorly described for many anuran species. Here we describe the advertisement and release calls of the tree frog Phyllomedusa ayeaye (Lutz, 1966) and report on the social context of emiss

30. Anuros da região do Médio Rio Jaguaribe, estado do Ceará, Nordeste do Brasil
A Região do Médio Rio Jaguaribe é uma área pobremente amostrada no domínio das Caatingas, localizada no leste do Estado do Ceará, Nordeste do Brasil. O Ministério do Meio Ambiente considera esta região como uma área prioritária para conservação e realização de inventários. Com o objetivo de preencher esta lacuna do conhecimento sobre a biodive

31. Diversidad, distribución espacio-temporal y turnos de vocalización de anuros (Amphibia, Anura) en un área ecotonal del nordeste de Argentina
ABSTRACT Studies on diversity and natural history of anuran communities are basic to distinguish natural fluctuations from those due to human impacts (a key tool in conservation programs), to assess the role they play in ecosystems dynamics and to allow comparison of diversity gradients. With those objectives, this paper analyzes diversity, temporal and spat

32. Cytogenetic studies in six species of Scinax (Anura, Hylidae) clade Scinax ruber from northern and northeastern Brazil
Scinax species are still underrepresented in cytogenetic studies, mainly with respect to populations from northeastern and northern Brazil. In this study, we provide new chromosomal information on Scinax boesemani, S. camposseabrai, S. garbei, S. pachycrus, S. trilineatus and S. x-signatus, all belonging to clade S. ruber. They were collected at two location

33. Advertisement call of Dendropsophus microps (Anura: Hylidae) from two populations from southeastern Brazil
In anurans, acoustic communication is a major mechanism of pre-zygotic isolation, since it carries information about species recognition. Detailed descriptions of the acoustic properties of anuran advertisement calls provide important data to taxonomist and to the understanding of the evolution of the group. Herein we re-describe the advertisement call of th

34. Richness, breeding environments and calling activity of the anurofauna of the lower moa river forest, state of Acre, Brazil
In state of Acre, most anuran research has been carried out in areas of terra firme, whereas alluvial forests remain relatively unexplored. We document the richness, breeding environments and calling season of the anurans of the Lower Moa River in the Alto Juruá (state of Acre), a region considered to harbor high biodiversity. Sampling was conducted in two

Anfíbios são hospedeiros para uma grande variedade de ecto- e endoparasitos, tais como os protozoários e vermes parasitos. Naididae é uma família de Oligochaeta cujas espécies vivem em uma ampla variedade de substratos, incluindo moluscos, macrófitas aquáticas, esponjas, musgos, e algas hepáticas e filamentosas. No entanto, algumas espécies são co

36. Aspectos reproductivos de Dendropsophus sanborni (Anura, Hylidae) en el nordeste de la Argentina
Reproductive aspects of Dendropsophus sanborni (Anura, Hylidae) in northeastern Argentina. The aim of this investigation was to characterize reproductive aspects of Dendropsophus sanborni (Schmidt, 1944) (Anura, Hylidae) in the northwest of Corrientes province, in northeastern Argentina. The reproductive cycles of males and females, the existence of sexual d
