Anuran diversity (Amphibia, Anura) in a Seasonal Forest fragment in southern Brazil Biota Neotropica
Bastiani,Veluma Ialú Molinari De; Lucas,Elaine Maria.
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...

Anuran interactions with the bromeliad Bromelia balansae in the Brazilian Pantanal. Repositório Alice
MORAVEC. J.; CAMPOS, Z..
Different frog-bromeliad associations are frequently reported from various habitats of Central and South America. Here, we present the first data on the association of two hylid species (Dendropsophus nanus and Scinax nasicus) with the bromeliad Bromelia balansae in the Brazilian Pantanal. Both treefrog species use rosettes of B. balansae as a diurnal shelter and foraging ground.

Determining sexual dimorphism in frog measurement data: integration of statistical significance, measurement error, effect size and biological significance Anais da ABC (AABC)
Hayek,Lee-Ann C.; Heyer,W. Ronald.
Several analytic techniques have been used to determine sexual dimorphism in vertebrate morphological measurement data with no emergent consensus on which technique is superior. A further confounding problem for frog data is the existence of considerable measurement error. To determine dimorphism, we examine a single hypothesis (Ho = equal means) for two groups (females and males). We demonstrate that frog measurement data meet assumptions for clearly defined statistical hypothesis testing with statistical linear models rather than those of exploratory multivariate techniques such as principal components, correlation or correspondence analysis. In order to distinguish biological from statistical significance of hypotheses, we propose a new protocol that...

Feeding habits and microhabitat utilization by two syntopic Brazilian Amazonian frogs (Hyla minuta and Pseudopaludicula sp. (gr. falcipes) BJB
VAN SLUYS,M.; ROCHA,C. F. D..
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...

Feeding habits of six anuran (Amphibia: Anura) species in a rainforest fragment in Northeastern Brazil Iheringia, Sér. Zool.
Santos,Ednilza M.; Almeida,Argus V.; Vasconcelos,Simão D..
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...

First record of growth rings for 11 native subtropical anuran species of South America Anais da ABC (AABC)
BRUM,AMANDA J.C.; LOEBENS,LUIZA; SANTOS,MAURÍCIO B. DOS; CECHIN,SONIA Z..
Abstract: Skeletochronology is the most accurate method to estimate a population age structure. The methodology is based on the analysis of secondary bone tissue in order to count growth rings. This study aimed to provide initial data, allowing researchers to further work out in the age of individuals and populations, sampling evidence of the presence of growth rings in 11 native species (representing nine families) of a subtropical region of southern Brazil. Four bone samples of each specimen were used to perform the skeletochronological analysis: the penultimate phalanges of the 3rd and 4th fingers, the humerus, and the femur. The presence of growth rings was confirmed in the periosteal layer of the bones of all analyzed species. In comparison with...

Tecnologia do processamento de carne do dorso de rã desfiada em conserva. Infoteca-e
FURTADO, A. A. L.; MACHADO, R. L. P.; DUTRA, A. de S.; CRIBB, A. Y.; FREIRE JUNIOR, M..
A carne de rã se destaca pelo seu sabor suave e pela sua textura. Além disso, se apresenta como reserva proteica de elevado valor biológico e baixo teor de gorduras, uma característica diferencial desse produto que é valorizada pelos seus consumidores habituais. Os cortes explorados após o abate se resumem à coxa e ao dorso. A coxa é o corte mais valorizado no mercado, devido à sua quantidade de carne e o dorso apresenta baixo valor devido ao alto percentual de ossos e cartilagem. A atividade da cadeia produtiva da rã é na sua maioria desenvolvida por pequenos produtores que a têm como principal fonte de renda. Em um contexto econômico no qual se busca a eficiência na produção e agregação de valor, não há espaço para descarte dos dorsos que podem...

The use of singleplex and nested PCR to detect Batrachochytrium dendrobatidis in free-living frogs BJM
Coutinho,Selene Dall'Acqua; Burke,Julieta Catarina; Paula,Catia Dejuste de; Rodrigues,Miguel Trefaut; Catão-Dias,José Luiz.
Many microorganisms are able to cause diseases in amphibians, and in the past few years one of the most reported has been Batrachochytrium dendrobatidis. This fungus was first reported in Brazil in 2005; following this, other reports were made in specimens deposited in museum collections, captive and free-living frogs. The aim of this study was to compare singleplex and nested-PCR techniques to detect B. dendrobatidis in free-living and apparently healthy adult frogs from the Brazilian Atlantic Forest. The sample collection area was a protected government park, with no general entrance permitted and no management of the animals there. Swabs were taken from the skin of 107 animals without macroscopic lesions and they were maintained in ethanol p.a. Fungal...
