| Behavioral studies of birds have reported several functions for active anting. Maintenance of plumage and prevention from ectoparasites are some examples. In this context, anting by males may be of particular importance in a classical lek mating system, where male-male competition is common and individuals with higher fitness may be more successful at attracting of females. In the present note, I describe the anting behavior of White-bearded Manakin (Manacus manacus) and I relate it to lek breeding and feeding (frugivory) habits of the species. Males used up to seven Solenopsis sp. ants. They rubbed each small ant from 4 to 31 times on undertail feathers until the ants were degraded; ants were not eaten. Males then searched for a new ant in the court.... |

| The genus Indigofera (Fabaceae) is used in folk medicine to treat gastrointestinal pain. In this study, we investigated the antiulcerogenic properties of Indigofera truxillensis Kunth. Oral administration of MeOH extract did not produce any signals of acute toxicity. The antiulcerogenic activity was assessed in different models of acute gastric ulcers (100% ethanol, piroxicam 30 mg.kg-1, hypothermic restraint stress and pylorus ligature) in mice and rats. The animals were treated with the drugs lanzoprazole (30 mg.kg-1) or cimetidine (100 mg.kg-1) as positive controls depending on the performed model. In another experiment with ethanol-induced ulcers in rats, N-ethylmaleimide (NEM), a sulfhydryl group blocker, was also used. The MeOH extract, at doses of... |

| In the Pantanal, the largest continuous floodplain in the world, the diversity and distribution of anuran amphibians vary in and across distinct subregions and distinct habitats occurring along inundation gradients. Permanent and natural aquatic habitats are relatively scarce in the Pantanal, and occurrence of temporary aquatic habitats varies seasonally, depending on rains. We here present results of evaluations of anuran's species richness and abundance in a seasonally flooded area in the northwestern section of the Pantanal (Fazenda Baía de Pedra, Cáceres municipality, state of Mato Grosso, Brazil), comparing values obtained in 10 plots systematically distributed over 5 km² with those obtained in additional aquatic plots in the study area. Data were... |

| Abstract: The state of Paraná, located in southern Brazil, was originally covered almost entirely by the Atlantic Forest biome, with some areas of Cerrado savanna. In the present day, little of this natural vegetation remains, mostly remnants of Atlantic Forest located in the coastal zone. While some data are available on the anurans of the state of Paraná, no complete list has yet been published, which may hamper the understanding of its potential anuran diversity and limit the development of adequate conservation measures. To rectify this situation, we elaborated a list of the anuran species that occur in state of Paraná, based on records obtained from published sources. We recorded a total of 137 anuran species, distributed in 13 families. Nineteen of... |

| 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... |

| Abstract: We provide information on the diversity and natural history of anurans from preserved and disturbed habitats in the region of Etá Farm, municipality of Sete Barras, state of São Paulo, Brazil. The region is covered by rainforest and plantations of banana and peach palm. From April, 2013 to March, 2014 we sampled amphibians mainly with pitfall traps with drift fences and visual and auditory surveys. A total of 9813 individuals of 36 species of anurans from nine families were recorded in this study. A larger number of species was found in forests (29 species), followed by peach palm plantations (21 species), and banana plantations (17 species). The areas of peach palm plantation and forests showed the greatest similarity in species composition. The... |

| The Middle Jaguaribe River region is a poorly sampled area in the Caatingas domain, located in the eastern Ceará State, northeastern Brazil. The Brazilian government agencies considered this region as a priority area for conservation and inventories. In order to fill this biodiversity knowledge gap, we conducted a ten-day rapid inventory of the anuran fauna from April 11 to 20, 2014, surveying different physiognomies of the region. We recorded 19 anuran species belonging to five families: Bufonidae (2), Hylidae (5), Leptodactylidae (9), Microhylidae (2) and Odontophrynidae (1). Most inventories of Caatinga amphibians published to date have been conducted inside protected areas and/or of high altitude (mesic areas known as "brejos de altitude"). The list we... |

| The Upper Paraguay River Basin is located in the center of South America and harbors one of the largest wetland in the world, known as Pantanal. This floodplain is surrounded by uplands, which presently have most of their area converted into pastures or monocultures, besides being poorly known scientifically. Also, most of these upland areas are considered conservation priorities. Here we present a list of anuran species from a savanna-like area (municipality of Camapuã, state of Mato Grosso do Sul, Brazil) inserted in the uplands surrounding the Pantanal floodplain, in the Upper Taquari River sub-basin, and evaluate the effectiveness of the sampling effort. Data were obtained through active searches in 22 plots in aquatic habitats, during the rainy season... |

| We studied the richness and distribution of anuran species on different breeding sites at the Reserva Ecológica da Michelin (13° 50' S and 39° 10' W, approximately 90-400 m above sea level), Municipality of Igrapiúna, Bahia State, Brazil. The reserve includes fragments of Atlantic Rain Forest varying from 140 to 650 ha. Five types of environments were sampled: leaf litter inside forest fragments, streams inside forest fragments, dam on the edge of forest fragment, temporary pond inside forest, and temporary ponds inside banana and rubber groves along the eastern boundary of the reserve. We used active and passive sampling methods for surveys of amphibians, between March 2007 and December 2008. We captured 48 species distributed in 10 families (number of... |

| Insular habitats are considered ideal for biogeographic studies, as they represent almost closed habitats with known formation timelines. Although São Paulo state in Brazil has a large number of continental and oceanic islands, few studies have examined the composition of the fauna in each locality. These studies are crucial to determine the community structure and to make biogeographic and phylogenetic inferences. From February 2007 to January 2009, we surveyed the anuran community of sandy coastal plains in four municipalities of the Lagamar Paulista: Cananéia, Ilha Comprida, Iguape and Pariquera-Açu, in the state of São Paulo, Brazil. This region is located in the Cananéia-Iguape estuary complex, comprising three continental islands: Ilha de Cananéia,... |

| O Parque Estadual da Ilha do Cardoso é uma área de grande importância para a conservação, pois abriga diferentes ecossistemas costeiros, como manguezais, dunas, restingas e mata atlântica de encosta, que, historicamente, estiveram sob forte pressão antrópica. A identificação duvidosa e a descoberta de novas espécies da anurofauna em ambientes costeiros, evidencia a escassez de estudos nessas regiões. Inventariamos a anurofauna da floresta de restinga do Parque Estadual da Ilha do Cardoso entre outubro de 2005 e outubro de 2007, por meio de 25 viagens mensais de dois dias de duração. Foram utilizados dois métodos: procura visual ativa em uma parcela permanente de 10 ha e procura visual e auditiva em nove sítios de reprodução. A anurofauna da área de estudo... |

| O município de São José do Barreiro (SP), localizado no domínio da Floresta Atlântica, em altitudes que oscilam entre 480 e 2088 m, apresenta grande complexidade topográfica e climática, que resulta na presença de inúmeras fitofisionomias, como os Campos de altitude, Floresta Estacional Semidecidual e Florestas Ombrófilas Densa e Mista. O objetivo deste estudo foi verificar a riqueza de espécies de anuros em duas áreas deste município: uma de Floresta Estacional Semidecidual e outra de Floresta Ombrófila Densa. Foram realizadas buscas ativas diurnas e noturnas, entre abril de 2004 e dezembro de 2006. O inventário resultou no registro de 35 espécies de anuros de nove famílias. A riqueza de espécies observada na área de estudo é similar a de outras... |
