1. Environmental parameters affecting the structure of leaf-litter frog (Amphibia: Anura) communities in tropical forests: a case study from an Atlantic Rainforest area in southeastern Brazil
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 of these animals. We analyzed the effects of some environmental factors on a leaf litter frog community at an Atlantic Rainforest area in southeastern Brazil. D

2. 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

3. 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

4. Parameters from the community of leaf-litter frogs from Estação Ecológica Estadual Paraíso, Guapimirim, Rio de Janeiro State, southeastern Brazil
Estudamos a comunidade de anuros de folhiço da EstaçãoEcológica Estadual Paraíso, em Guapimirim, estado do Rio de Janeiro, no sudeste do Brasil. Combinamos três métodosde amostragem (plots, transectos e armadilhas de queda) para apresentar dados sobre a composição de espécies, riqueza,abundância relativa e densidade. A assembleia local foi compost

5. Comunidades de anfíbios anuros em duas fitofisionomias do Parque Estadual da Serra do Tabuleiro, estado de Santa Catarina / Anuran communities in two phytofisionomies in Serra do Tabuleiro State Park, state of Santa Catarina, Brazil.
O estado de Santa Catarina possuía sua área inteiramente coberta por Mata Atlântica, um dos biomas mais ameaçados mundialmente. Mesmo com o crescente aumento de informações sobre os anfíbios no estado, ainda existe muitas lacunas de informações para este grupo e o desconhecimento é alto mesmo no interior das Unidades de Conservação. O Parque Esta

6. Ecology of Ischnocnema parva (Anura: Brachycephalidae) at the Atlantic Rainforest of Serra da Concórdia, state of Rio de Janeiro, Brazil
Ischnocnema (Brachycephalidae) includes many species that are important members of the leaf litter frog communities in the Atlantic Rainforest of Brazil. Ischnocnema parva (Girard, 1853) is endemic to the Atlantic Rainforest biome and is restricted to the forests of southeastern Brazil. Currently, the available information about the ecology of I. parva is sc

7. Density and richness of leaf litter frogs (Amphibia: Anura) of an Atlantic Rainforest area in the Serra dos Órgãos, Rio de Janeiro State, Brazil
Data on species composition, richness, and density are presented for the leaf litter frog assemblage of an area of Atlantic Rainforest at the Serra dos Órgãos mountain range, in the state of Rio de Janeiro, southeastern Brazil. Three sampling methods were used: plot sampling, visual encounter surveys, and pitfall traps. The local assemblage of leaf litter

8. 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

9. Multiple, recurring origins of aposematism and diet specialization in poison frogs
Aposematism is the association, in a prey organism, of the presence of a warning signal with unprofitability to predators. The origin of aposematism is puzzling, because of its predicted low probability of establishment in a population due to the prey's increased conspicuousness. Aposematism is a widespread trait in invertebrate taxa, but, in vertebrates, it

10. Bioactive alkaloids of frog skin: Combinatorial bioprospecting reveals that pumiliotoxins have an arthropod source
Nearly 500 alkaloids have been detected in skin extracts from frogs of the family Dendrobatidae. All seem to have been sequestered unchanged into skin glands from alkaloid-containing arthropods. Ants, beetles, and millipedes seem to be the source of decahydroquinolines, certain izidines, coccinellines, and spiropyrrolizidine oximes. But the dietary source fo
