| Physical maps of the ribosomal RNA gene 28S of species belonging to the genera Paratelmatobius and Scythrophrys were constructed, using five restriction endonucleases. The restriction sites for Bam HI, Bgl II, Bst EII, and Eco RI had similar positions in all species, although there were interspecific differences in the size of the restriction fragments obtained. An additional Pvu II site was found in Scythrophrys specimens from Piraquara (State of Paraná, Brazil) and from São Bento do Sul (State of Santa Catarina, Brazil), but not in the Scythrophrys specimens from Rancho Queimado (State of Santa Catarina, Brazil). This finding is in agreement with the hypothesis regarding the existence of two species in the genus Scythrophrys. On the other hand, the extra... |

| Abstract Two allopatric populations of Brazilian diploid and tetraploid Odontophrynus americanus species complex, both from São Paulo state, had their blood hemoglobin biochemically analyzed. In addition, these specimens were cytogenetically characterized. Biochemical characterization of hemoglobin expression showed a distinct banding pattern between the allopatric specimens. Besides this, two distinct phenotypes, not linked to ploidy, sex, or age, were observed in adult animals of both populations. Phenotype A exhibits dark-colored body with small papillae, ogival-shaped jaw with reduced interpupillary distance and shorter hind limbs. Phenotype B shows yellowish-colored body with larger papillae, arch-shaped jaw with broader interpupillary distance and... |

| Abstract Cytogenetic data can be useful for taxonomic and phylogenetic studies, as well as to provide information about chromosome evolution. Therefore, it may help design conservation priorities for some threatened species, such as anurans. Herein, we describe the karyotypes of Scinax constrictus and Ololygon centralis, native endemic species from the Brazilian Cerrado. Chromosome preparations for both species were stained with Giemsa for morphological analyses and then impregnated by the Ag-NOR method for localization of the nucleolar organizer region (NOR). Both species had 24 chromosomes, as confirmed by meiotic analyses, which showed 12 bivalents. Chromosome morphologies presented the same pattern for Scinax and Ololygon compared to species already... |

| Male-male and male-female interactions, reproductive habitat, and vocalizations of Hyla goiana B. Lutz, 1968 a member of H. polytaenia species group, are described. Three groups of calling males were surveyed along a small stream, at the Estação de Pesquisa e Desenvolvimento Ambiental de Galheiro, Perdizes municipality, State of Minas Gerais, Brazil. The mean distance between the nearest calling neighbors was 2.7 m, in accordance with an uniform distribution. Clutches (mean 180 eggs) were deposited in the stream, submerged and attached to plants. In two observed courtships the female moved towards a calling male that rapidly clasped her. In the male-male interaction, the males emitted advertisement and encounter calls and then engaged in physical combat.... |

| A riqueza e a diversidade de anfíbios anuros de serapilheira em áreas de floresta e de pastagem foram estudadas em Rondônia. A eficiência da utilização de armadilhas de interceptação e queda foi analisada. As armadilhas foram instaladas em três ambientes distintos: interior de floresta, distante de ambientes aquáticos permanentes; interior de floresta, a cerca de 100 metros de rio; área de pastagem, distante de ambientes aquáticos permanentes. Foram capturados 1.324 espécimes pertencentes a 27 espécies, distribuídas em nove famílias: Aromobatidae (1 espécie), Brachycephalidae (2), Bufonidae (4), Cycloramphidae (1), Dendrobatidae (1), Hylidae (5), Leiuperidae (1), Leptodactylidae (7) e Microhylidae (5). O emprego de armadilhas de interceptação e queda... |

| A diversidade biológica e os processos ecológicos do bioma Cerrado ainda são pouco conhecidos. Neste estudo são apresentadas informações acerca da estrutura da anurofauna do município de Barro Alto, estado de Goiás (Brasil Central). Cinco corpos d'água foram amostrados entre os anos de 2007 a 2010 (outubro-março), três deles associados à área florestal e dois associados à área aberta. Registraram-se 39 espécies de anuros, caracterizados como especialistas de hábitat aberto, florestal ou generalistas. A curva de acumulação de espécies apresentou a formação de uma assíntota, evidenciando que as técnicas e esforço de amostragens foram adequados para se estimar a riqueza de espécies de anuros na região. A riqueza foi influenciada pela umidade e temperatura, já... |

| Physalaemus henselii (Peters, 1872) is a little known leiuperid frog that has not been studied since the 1960s. Herein, we redescribe its advertisement call, and assess the female sexual cycle and the reproductive period on the basis of the macroscopic analysis of the ovaries and field observations. The Ovarian Size Factor (OSF) was calculated. The study was made in Departamento de Rivera, northern Uruguay. The advertisement call consists of short (177 ± 21ms), multipulsed (20 ± 3 pulses/note) notes, with a note repetition rate of 1.57 ± 0.13 notes/s. Physalaemus henselii has a female sexual cycle with unimodal distribution of gravid females, which are present from February to September. The OSF and the ratio "females with mature oocytes / females without... |

| The vocalizations of H. raniceps (Cope, 1826) and their functions are described, including an analysis of the influence of temperature, weight, or SVL (snout-vent length) of males on the acoustic parameters. The vocalizations were recorded in three areas in Fazenda Lagoa Grande, Municipality of Pontalina, State of Goiás, central Brazil. Males began their vocalizations just before sunset, extending them, in some cases, to dawn of the following day. The peak of activities happened between 21h and 23h. The height of calling sites varied plenty, being the position horizontal in about 50% of them. Males defended sites in different areas during consecutive nights. Rain and strong winds interrupted the calling activities. Males emitted three vocalizations:... |

| Reproductive modes and size-fecundity relationships are described for anurans from Picinguaba, a region of Atlantic rainforest on the northern coast of the state of São Paulo, Brazil. We observed 13 reproductive modes, confirming a high diversity of modes in the Atlantic rainforest. This diversity of reproductive modes reflects the successful use of diversified and humid microhabitats by anurans in this biome. We measured the snout-vent length of 715 specimens of 40 species of anurans. The size-fecundity relationship of 12 species was analyzed. Female snout-vent lengths explained between 57% and 81% of clutch size variation. Anurans with aquatic modes laid more eggs than those with terrestrial or arboreal modes. Larger eggs were deposited by species with... |

| During field work in Venezuela and Brazil a difference in call was noticed between specimens of large hylids of the Hyla boans-group. Based on this and on morphological differences, it was concluded that Hyla wavrini Parker, 1936, up till now considered a synonym of Hyla boans (Linnaeus, 1758), should be considered a valid species, of which Hyla miranda-ribeiri Melin, 1941 is a synonym. Durante trabajo de campo en Venezuela y el Brasil se nota una diferencia en el canto de especimenes de gran Hílidos del grupo Hyla boans. Basandose en este observación y en diferencias morfológicas, se concluye que Hyla wavrini, considerado até horita como sinónimo de Hyla boans debe ser considerado como especie valido, y que Hyla miranda-ribeiri es un sinónimo de el.... |

| Dramatic global amphibian declines have recently led to an increased concern for many species of this animal class. The enigmatic Hula painted frog (Latonia nigriventer), the first amphibian to be declared extinct but unexpectedly rediscovered in 2011, has remained one of the rarest and most poorly understood amphibians worldwide. Gathering basic biological information on this species, along with an understanding of its disease-related threats remains fundamental for developing risk assessments and conservation strategies. Our surveys in recent years confirmed that L. nigriventer is a localised species with elusive habits. The species appears to follow an opportunistic breeding phenology and has a tadpole morphology similar to its well-studied sister group... |

| Study of the type specimens of B. caeruleostictus Günther, 1859 and B. chanchanensis Fowler, 1913, and of fresh material showed that B. chanchanensis is a junior subjective synonym of B. caeruleostictus. Probably it is a member of the B. guttatus group. B. caeruleocellatus Fowler, 1913 is a junior subjective synonym of B. haematiticus Cope, 1862. New material of B. hypomelas Boulenger, 1913 is reported from NW Ecuador, the species is redescribed, and it is shown that this is a valid taxon, not the juvenile of B. blombergi Myers & Funkhouser, 1951 as suggested by Lynch, in Frost (1985). It is doubted whether B. intermedius Günther originates from Ecuador. It probably is a Central American or Mexican species of the B. valliceps Wiegmann, 1833 group. A... |
