1. Seasonal variation in the leaf-litter frog community (Amphibia: Anura) from an Atlantic Forest Area in the Salto Morato Natural Reserve, southern Brazil
In this study we provide the first data regarding community parameters of leaf-litter anurans inhabiting a forest floor in the state of Paraná, southern Brazil, including information on community species richness, composition, specific density and biomass. Our study was conducted at Salto Morato Natural Reserve using forty plots of 4 x 4 m for each one of t

2. Editorial
Saddleback toads (Brachycephalidae: Brachycephalus) are a remarkable group of highly endemic species from the southern Atlantic Rainforest of Brazil. They are brightly colored, diurnal, minute frogs that live in the leaf litter of high-elevation cloud forests. Little is known about the natural history of these frogs, particularly their diet. In the present s

3. Anurans from two high-elevation areas of Atlantic Forest in the state of Rio de Janeiro, Brazil
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 in two high-altitude (i.e. > 1000 m) sites within the Parque Estadual dos Três Picos (PETP), in the state of Rio de J

5. Chromosomal and sperm ultrastructure studies of brazilian species of Terrarana (Amphibia : Anura) / Analise de especies brasileiras de Terrarana (Amphibia : Anura) utilizando estudos cromossomicos e da ultra-estrutura do espermatozoide
The Terrarana is the largest taxon of the Anura order, comprising 900 species. Recently this anuran group has undergone a series of taxonomical rearrangements. At first, these species were removed from the Leptodactylidae family and transferred to the synonymy of Brachycephalidae, and lately they were placed into a new taxon named Terrarana. Currently, the T

6. Osteologia de Brachycephalus (Anura: Brachycephalidae): desenvolvimento e diversidade morfológica das placas ósseas, região auditiva e sua importância para o monofiletismodo gênero
O surgimento de novidades morfológicas e o aumento de tamanho e de complexidade são eventos evolutivos raros. Por outro lado, a redução de tamanho e a perda de estruturas e de complexidade talvez sejam os eventos mais comuns no processo evolutivo. No gênero Brachycephalus, encontramos um mosaico dessas duas tendências: simplificação e novidades morfo

8. Levantamento preliminar da mastofauna da região de Anajás-Muaná, Ilha de Marajó, Pará, Brasil
A short inventory of the mammalian fauna occurring in an area of the Marajó Island was performed during the rainy season. In addition to captures by using Sherman and Tomahawk traps, and mist-nets, indirect evidence was considered, e.g. finding of body fragments of specimens, vocalization, and testimonies from local people. A total of 57 species (22 familie

9. Diversidade e densidade de anuros de serralheria num gradiente altitudinal na mata atlantica costeira
Here I present and discuss data about the diversity and abundance ofleaf-litter frogs along an altitudinal gradient (0-1.000 m) in Ubatuba, São Paulo, (Southeastem Brazil). I sampled the area in three transects, with 64 fenced plots (8 x 8 m) in the summer and 32 in the winter. I considered 11 altitudinal strips, from the plains to the top of the hills. In
