| Although Brazil encompasses one of the most abundant anuran faunas in the world, quantitative information on anuran ecology and diet are limited, especially in the Northeastern region. We analyzed the diet of six species: Hyla albomarginata, Hyla cf. branneri, Hyla minuta, Phyllomedusa aff. hypochondrialis (Hylidae), Leptodactylus natalensis, and Physalaemus cuvieri (Leptodactylidae) in a temporary pond in a rainforest remnant in Pernambuco, between 1999-2000. We analyzed diet composition, degree of food preference, and seasonal variations in diet. Leptodactylus natalensis and P. cuvieri showed higher diet diversity, whereas H. minuta consumed fewer food items. Insecta, Arachnida, and plants were preferential items for most species. Acari were consumed by... |

| The Atlantic Forest is the home to a diverse and threatened fauna of amphibians. However, knowledge on these species is still scarce to many of its ecosystems, such as the Seasonal Forest. This study was aimed at determining the diversity of anurans in Parque Estadual Fritz Plaumann (PEFP), located in the municipality of Concórdia, Santa Catarina, southern Brazil. The PEFP comprises 741 ha, and is the only Conservation Unit of Seasonal Forest in Santa Catarina state. From August 2010 to July 2011 we surveyed frogs fortnightly during four to ten days, from sunset until approximately midnight. Active, audio and visual searches were carried out at breeding sites and favorable areas to meet the species. The sampling effort of the survey was evaluated with... |

| We studied the feeding habits and microhabitat use of the Amazonian frogs Hyla minuta and Pseudopaludicula sp. at Serra Norte, Carajás, Brazil. Although living syntopically, the two species differed markedly in both prey types and sizes. Standardized feeding niche breadth of H. minuta (Bst = 0.572) was larger than that of Pseudopaludicula sp. (Bst = 0.149) and their feeding niche overlap was considerably low (10.5%). The two frog species also differed in microhabitat use. When active, Pseudopaludicula sp. were found partially submerged at the lake border whereas H. minuta were found predominantly on Nymphaea sp. leaves. Although we have not evaluated taxonomic effects on diet composition, differences in diet may be partially explained by differences in... |
