A new species of Telmatobufo (Schmidt 1852) (Anura, Calyptocephalellidae) from a remnant of the Maulino Forest, central Chile
Provedor de dados: Gayana
Autores: Cuevas,César C.
A new species, Telmatobufo ignotus, from the Reserva Nacional Los Queules, Cauquenes Province, central Chile is described herein. The new taxon is hypothesized based on a new combination of adult, larval, and chromosomal characters. The new species present the more septentrional distribution on the coastal range and a very restrictive distribution area compared to its congeners; because of this, taxonomic and conservation comments are discussed and advanced.

Restriction fragment analysis of the ribosomal DNA of Paratelmatobius and Scythrophrys species (Anura, Leptodactylidae)
Provedor de dados: Genetics and Molecular Biology
Autores: Lourenço,Luciana B.; Garcia,Paulo C.A.; Recco-Pimentel,Shirlei M.
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...

Whole-genome duplication and hemoglobin differentiation traits between allopatric populations of Brazilian Odontophrynus americanus species complex (Amphibia, Anura)
Provedor de dados: Genetics and Molecular Biology
Autores: Cianciarullo,Aurora M.; Bonini-Domingos,Claudia R.; Vizotto,Luiz D.; Kobashi,Leonardo S.; Beçak,Maria-Luiza; Beçak,Willy.
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...

Autores: Targueta,Cíntia Pelegrineti; Guerra,Vinícius; Gambale,Priscilla Guedes; Bastos,Rogério Pereira; Silva,Daniela de Melo e; Telles,Mariana Pires de Campos.
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...

Hypothesis testing of genetic similarity based on RAPD data using Mantel tests and model matrices
Provedor de dados: Genetics and Molecular Biology
Autores: Rodrigues,Flávia Melo; Diniz-Filho,José Alexandre Felizola; Bataus,Luiz Artur Mendes; Bastos,Rogério Pereira.
Clustering and ordination procedures in multivariate analyses have been widely used to describe patterns of genetic distances. However, in some cases, such as when dealing with Jaccard coefficients based on RAPD data, these techniques may fail to represent genetic distances because of the high dimensionality of the genetic distances caused by stochastic variation in DNA fragments among the units analyzed (species or populations). In this note, we show how Mantel tests can be used to test hypotheses about genetic distances and avoid problems with multivariate data representation. The procedure is illustrated with RAPD data comparing 20 anuran species from the cerrado, in which Jaccard genetic distances were compared to three model matrices linking the...

B-chromosomes in two Brazilian populations of Dendropsophus nanus (Anura, Hylidae)
Provedor de dados: Genetics and Molecular Biology
Autores: Medeiros,Lilian R.; Rossa-Feres,Denise C.; Jim,Jorge; Recco-Pimentel,Shirlei M.
We report on the presence of B-chromosomes in two populations of Dendropsophus nanus (= Hyla nana Boulenger, 1889) from São Paulo State, Brazil. Such chromosomes were observed in 4 out of 43 specimens (9.3%) and in 9 out of 15 specimens (60%) from the municipalities of Nova Aliança and Botucatu, respectively. The karyotype 2n = 30 + 1B found in D. nanus was similar to that of other species with 2n = 30 chromosomes, except for the presence of an additional small telocentric chromosome. In one specimen from Botucatu, cells with one to three extra chromosomes were observed. These B-chromosomes appeared as univalent in meiosis I and did not bear a nucleolar organizer region or exhibit constitutive heterochromatin.

Autores: Menin,Marcelo; Silva,Rodrigo A.; Giaretta,Ariovaldo A.
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....

Physalaemus henselii (Peters, 1872) is a little known leiuperid frog that has not been studied since the 1960’s. 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:...

Provedor de dados: Iheringia Série Zoologia
Autores: Zieri,Rodrigo; Taboga,Sebastião R.; Oliveira,Classius de.
A maturação dos espermatozóides envolve um extenso e complexo processo que começa com a proliferação e diferenciação das espermatogônias, passa pela meiose e finaliza com a espermiogênese. Nessa fase, eventos envolvendo alterações morfológicas e bioquímicas transformam espermátides em espermatozóides. Aspectos ultra-estruturais da espermiogênese e do espermatozóide do anuro Eupemphix nattereri (Steindachner, 1863) foram analisados através de microscopia eletrônica de transmissão. A espermiogênese envolve condensação da cromatina e alongamento nuclear, com visível eliminação de citoplasma. Nesse estágio, grande quantidade de microtúbulos e glicogênio podem ser visualizados no citoplasma das células de Sertoli, rodeando cada espermátide. O espermatozóide é...

Reproductive modes and fecundity of an assemblage of anuran amphibians in the Atlantic rainforest, Brazil
Provedor de dados: Iheringia Série Zoologia
Autores: Hartmann,Marilia T; Hartmann,Paulo A; Haddad,Célio F. B.
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...

Resurrection of Hyla wavrini Parker (Amphibia: Anura: Hylidae), a gladiator frog from northern South America
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hoogmoed, M.S.
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 &amp; Funkhouser, 1951 as suggested by Lynch, in Frost (1985).

Autores: Vejarano, S.; Thomas, M.; Vences, M.
We describe the tadpoles of three species of Malagasy frogs, classified in the genus Spinomantis, based on specimens identified by DNA barcoding. The tadpole of Spinomantis aglavei is a typical Orton type IV larva. The oral disc is not emarginated laterally, but has two mid-ventral folds and a labial tooth row formula of 3(2- 3)/2(1). The tadpole of S. phantasticus is similar, the oral disc being laterally emarginated and having one medial fold; LTRF is 3/3(1). A third species, S. cf. fimbriatus is also similar to the other two species; the oral disc is not laterally emarginated but has three medial folds and LTRF is 3(2-3)/3(1). One shared character is a median fold or emargination in the lower part of the oral disc, although the shape of this fold is...

Natural history and distribution of Agalychnis craspedopus (Funkhouser, 1957) (Amphibia: Anura: Hylidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hoogmoed, M.S.; Cadle, J.E.
Aspects of reproductive behaviour, calls, clutch sizes, and larval morphology are described for Agalychnis craspedopus (Funkhouser, 1957). New distributional records extend the range of this species to southern Amazonian Peru. In most respects reproductive behaviour of A. craspedopus is similar to that of other phyllomedusine frogs. In southern Peru clutches were suspended above water-filled hollow cavities in logs, but in Ecuador tadpoles were found in a pool on the ground with no directlyoverhanging vegetation. Agalychnis craspedopus lays small clutches (mean = 17 eggs) with large eggs. Breeding possibly takes place throughout some years in southern Peru, but this undoubtedly varies depending on rainfall. Some aspects of reproductive biology, and tadpole...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Ascarrunz, E.; Rage , J.-C.; Legreneur, P.; Laurin, M.
Triadobatrachus massinoti is a batrachian known from a single fossil from the Early Triassic of Madagascar that presents a combination of apomorphic salientian and plesiomorphic batrachian characters. Herein we offer a revised description of the specimen based on X-ray micro-tomography data. We report previously unknown caudal vertebrae, possible mentomeckelians, and hidden parts of other structures. We also confirm the presence of a ventrolateral ledge on the opisthotic, and we rectify some previous interpretations. There are no cervical ribs and the jaw may have had an angular. The presacral region is composed of 15 vertebrae with a unique atlas-axis complex instead of 14 vertebrae with a bipartite atlas. The configuration of the pelvic girdle is not...

Rediscovery of a forgotten snake in an unexpected place and remarks on a small herpetological collection from southeastern Brazil
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hoogmoed, M.S.
A collection of snakes and frogs collected in the area of Porto Real, Rio de Janeiro State, Brazil, was bought in December 1890 and remained unidentified until now. The collection comprises 100 snakes belonging to 18 species and 152 frogs belonging to 19 species. A comparison with the herpetofauna from nearby Serra do Japi in São Paulo is made. General remarks on variation and identification are made for a number of species. Among the snakes were two specimens of Cercophis aurata (Schlegel, 1837), a species described on the basis of one specimen from Suriname, and no new specimens having been recorded until now. The new individuals cause the known area of distribution to be greatly enlarged, but such a large distribution area occurs in several other snakes...

Molecular phylogeny, morphology and bioacoustics reveal five additional species of arboreal microhylid frogs of the genus Anodonthyla from Madagascar
Provedor de dados: Naturalis Digital Academic Repository
Autores: Vences, M.; Glaw, F.; Köhler, J.; Wollenberg, K.C.
We provide a partial revision of the microhylid frogs of the genus Anodonthyla, endemic to Madagascar, based on comprehensive molecular, bioacoustic and morphological data sets that include newly collected specimens from multiple localities. The molecular trees provide strong evidence for the polyphyly of several nominal species as they were previously defined, especially of Anodonthyla boulengeri and A. nigrigularis. As a consequence, we here resurrect the nomen Mantella pollicaris Boettger as Anodonthyla pollicaris from the synonymy of A. boulengeri, and we describe four new species, all with strong genetic divergences to other nominal species: Anodonthyla emilei from Ranomafana National Park, a comparatively medium- sized species characterized by a...

A new genus and two new species of minute leptodactylid frogs from northern South America, with comments upon Phyzelaphryne (Amphibia: Anura: Leptodactylidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hoogmoed, M.S.; Lescure, J.
The synonymisation of Phyzelaphryne miriamae Heyer with Eleutherodactylus nigrovittatus Andersson is denied and it is shown that both species are quite distinct in numerous characters. A new genus (Adelophryne) of minute leptodactylid frogs with pointed discs on the toes and a distinctly reduced fourth finger, containing two new species (A. adiastola spec. nov. and A. gutturosa spec. nov.) is described from northern South America. A key to separate the diminutive leptodactylid frogs with pointed toetips is given. The relationships of the new genus are not clear, but possibly are with one of the species groups of Eleutherodactylus, of the subfamily Eleutherodactylinae.

New Osornophryne (Amphibia: Anura: Bufonidae) from the Atlantic Versant of the Andes in Ecuador
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hoogmoed, M.S.
Two species of the little known genus Osornophryne are described from the Atlantic (Amazonian) versant of the Andes in Ecuador. O. guacamayo spec. nov. occurs at 2100 m, has well developed cranial ridges, rather peculiar feet with toes IV and V of about equal length and much longer than the others. It is rather gaudily patterned with black and yellow. O. antisana spec. nov. occurs at 3600 m and has a pointed snout, indistinct cranial ridges and is rather drably coloured. The single available adult male has a cloacal tube that runs down the back of the thighs and opens ventrally. It is speculated that this peculiar structure is indicative of internal fertilization. It is concluded that inguinal amplexus in this genus is not a primitive, but an advanced...

Autores: Dorigo,Thiago Arnt; Vrcibradic,Davor; Rocha,Carlos Frederico Duarte.
Abstract. The amphibian fauna of the state of Rio de Janeiro, in southeatern Brazil, is characterized by high species richness and rates of endemism, and is still insufficiently known. A first list of amphibian species with occurrence in the state was published in 2004 and reported 166 taxa, but since then many new records, descriptions of new taxa, and revalidations and synonymizations of species have consistently improved the knowledge about the state’s amphibian biodiversity. Thus, a review and update of that list was deemed necessary. We herein present an updated and commented list of amphibian species occurring in the state of Rio de Janeiro based on a survey of the literature. We recorded the occurrence of a total of 201 species of amphibians (197...

Autores: MAGESKI,MARCIO MARQUES; FERREIRA,RODRIGO BARBOSA; COSTA,LARISSA CORTELETTI DA; JESUS,PAULO ROBERTO; FERREIRA,PAULO DIAS.
ABSTRACT Amphibians may use bromeliads for reproduction (i.e., bromeligenous species) or only for refuge and foraging (i.e., bromelicolous species). The partition of bromeliad resources is essential to maintain the coexistence of the associated assemblages. We sampled 913 bromeliads in a sandy coastal plain (i.e., restinga habitat) in southeastern Brazil and found 234 frogs belonging to seven species. One of the frog species was bromeligenous and the other six were facultative bromelicolous. The bromeliads of the genus Aechmea were the most frequently used by frogs. The low degree of frog occupancy of bromeliads (26%) suggests habitat segregation. Our study highlights the importance of maintenance of bromeliad species for conservation of the associated...

En 1980, Marco Antonio Serna colectó dos ejemplares de una inusual rana de cristal en el noroccidente del Departamento de Antioquia, Colombia. Dichos ejemplares exhibían algunas características sobresalientes entre las cuales llamó la atención su gran tamaño. Aparentemente solo uno de estos ejemplares (el holotipo hembra) fue enviado para su identificación a Juan A. Rivero, quien la describió bajo el nombre de Centrolenella megistra (Rivero, 1985). Sin embargo, escasa información concerniente a la especie ha sido reportada en la literatura desde la descripción original, más allá de su re-asignación genérica. En este trabajo, presentamos una redescripción de esta especie, con una adecuada delimitación de sus características, asignamos un neotipo,...

Provedor de dados: Papéis Avulsos de Zoologia
Autores: Prado,Gustavo M.; Bilate,Marcos; Wogel,Henrique.
The extensive vocal repertoire of Leptodactylus natalensis is described. The field observations were made at three forest fragments of the Tropical Atlantic Domain, in Northeast (State of Alagoas) and Southeast (State of Espírito Santo) regions of Brazil. The vocal repertoire of L. natalensis was constituted by ten notes emitted alone or in different combinations. The several vocalizations were organized in three distinct groups according to the social context in the moment of emission. L. natalensis presents extensive diversity of acoustic signals supported by variations in duration of each note, as well as in the number and sequence of emission of different notes.

ABSTRACT The Serra do Urubu mountain range is considered a key biodiversity area. It is situated in the Pernambuco Endemism Center, one of the most threatened regions of the Brazilian Atlantic Forest. However, despite the high importance of this area little research on its herpetofauna has been performed. The present study presents an inventory of the herpetofauna of the region, through bibliographic review, searches in museum collections and field expeditions to the RPPNs Frei Caneca and Pedra D’Antas, in the municipalities of Jaqueira and Lagoa dos Gatos. The conservation status of the amphibians of the region is discussed. Five expeditions, between 2012 and 2013 were made. The methods employed were visual transect surveys, acoustic census and pitfall...

Autores: Sabagh,Leandro Talione; Mello,Renata da Silva; Rocha,Carlos Frederico Duarte.
We studied the feeding habits and similarities in the diet of two sympatric and syntopic Amazonian frog species, Anomaloglossus stepheni (Aromobatidae) and Leptodactylus andreae (Leptodactylidae) in a forested area in Central Amazonia. The breadth of the trophic niche of these species was 5.89 and 3.75, respectively, and approximately 85% of their diets were similar. Ants were main food item in the diets of both frog species. The coexistence between these frog species may be facilitated by the significant differences in the size of their mouths. This difference allows them to consume preys items of different sizes.

BACKGROUND: Biotic processes, such as predation and parasitism events, are crucial for answering questions in ecology and evolution. Here, we report predation and ectoparasitism events of invertebrates upon tadpoles in aquatic habitats of southern Brazil. FINDINGS: Four lentic water bodies were sampled twice a month (December 2012 to March 2013). Those water bodies were located in the Diamante do Norte County, State of Paraná, southern Brazil. The tadpoles, Dendropsophus aff. minutus, Hypsiboas raniceps, Scinax fuscovarius, Physalaemus cuvieri and Elachistocleis bicolor were observed being predated by six different invertebrate predators. However, Leptodactylus fuscus and Pseudis sp. were also recorded on the same water bodies and were not observed being...

Reproductive behavior of Cycloramphus dubius Miranda-Ribeiro (Amphibia, Anura, Leptodactylidae)
Provedor de dados: Zoologia
Autores: Giaretta,Ariovaldo A; Cardoso,Adão J.
Cycloramphus dubius Miranda-Ribeiro. 1920 is a frog species from the coastal Atlantic Forest in Southeastern Brazil. It uses waterfalls of forested rivulets as breeding sites. The eggs are placed outside of water, between rock crevices or roots constantly wetted by water dripping. Clutches have about 60 eggs, and the tadpoles grow attached to rocks, out of water. Males of this species exhibit parental care, biting and/or pushing away strange objects approaching the egg masses. Two types of calls were identified in the spectrograms. The "advertisement calls" consist of juxtaposed pulses lasting 200ms; the "aggressive calls", also have the short pulses structure, and last around 300ms. The aggressive calls are emitted during territorial invasion.

Provedor de dados: Zoologia
Autores: Giaretta,Ariovaldo A.; Araújo,Márcio S.; Medeiros,Hermes F. de; Facure,Katia G.
Here is described the diet of Proceratophrys boiei (Wied, 1825), a leaf litter frog of the Atlantic Forest, and test for relationships between frog size and prey size and type. The diet was determined by stomach content analysis. In 38 frogs, was found 76 prey items belonging to 23 taxa. Insects predominate in the diet and the most frequent categories were coleopterans (39.4% of total volume) and orthopterans (25.0%). There was a positive correlation between frog size and volume of prey taken. The most important ontogenetic shift in prey type was an increase in the consume of coleopterans and insect larvae with increasing frog size.

Similaridade do sítio de vocalização em uma comunidade de anfíbios anuros na região noroeste do Estado de São Paulo, Brasil
Provedor de dados: Zoologia
Autores: Rossa-Feres,Denise de C.; Jim,Jorge.
The breadth and overlap of male call site were determined for 15 anuran species from a temporary pond in Northwestern São Paulo State, Brazil. Four measurements were made at the point of capture of each calling male and the frequency of mating call was determined. There was a high overlap along each variable of call site, but less than 28% of possible species pairs presented high overlap for all variables. Taxonomically related species pairs calling from grass presented spatial and acoustic segregation, while those calling from the graund presented only acoustic segregation. The similarity of call site seems to be not only related to the taxonomic relationships but also with the body size and spatial heterageneity.

Durante estudos com morcegos em floresta de várzea na APA do Rio Curiaú, Amapá, Brasil, observamos três casos de predações oportunistas de morcegos frugívoros capturados em redes de neblina. Duas destas predações ocorreram por marsupiais e uma por anuro. Artibeus planirostris (Spix, 1823) (Chiroptera, Phyllostomidae) foi predado por Didelphis marsupialis Linnaeus, 1758 e Philander opossum (Linnaeus, 1758) (Didelphimorphia, Didelphidae). Carollia perspicillata (Linnaeus, 1758) (Chiroptera, Phyllostomidae) foi predado por Leptodactylus pentadactylus (Laurenti, 1768) (Anura, Leptodactylidae). A vocalização dos morcegos provavelmente atraiu os marsupiais para a rede, onde estes os predaram aproveitando que estavam presos. Este tipo de interação pode ocorrer...

ABSTRACT Neotropical amphibians play important roles as preys and predators in freshwater and terrestrial ecosystems. The subfamily Pseudinae includes small and medium-sized frogs within three genera representing 13 valid species. Most published records of predation on Pseudinae frogs are anecdotic and scarce. Herein, we provide five new reports of predation and presenting a detailed literature review on Pseudinae predation, with 15 studies published between 1983-2017. Pseudinae species were preyed at both day and night by a wide variety of predators, principally birds. Adults were preyed upon more frequently than juveniles and tadpoles. In the present study, most predators were diurnal, with birds accounting for most records. A variety of invertebrates...

A simplified table for staging embryos of the pipid frog  Pipa arrabali
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: ARAÚJO,OLÍVIA G.S.; HADDAD,CÉLIO F.B.; SILVA,HÉLIO R. DA; PUGENER,LOURDES A.
ABSTRACT Pipa is a Neotropical genus of frogs that dwell in freshwater environments. It includes four species that lack free-swimming larvae (P. aspera, P. arrabali, P. pipa, and P. snethlageae) and three with tadpoles (P. carvalhoi, P. myersi, and P. parva). Developmental tables such as the one proposed by Nieuwkoop and Faber might be useful for Pipa species with tadpoles. However, for the other Pipa species, to determine stages by this table or by any of the tables already prepared for frogs without tadpoles (e.g., Crinia nimbus, Eleutherodactylus coqui, and Oreobates barituensis) is impossible. By using embryonic, juvenile, and subadult specimens, we generated a staging table for P. arrabali, from the moment limb buds were first observed until birth,...

The peculiar breeding biology of the Amazonian frog Allobates subfolionidificans (Aromobatidae)
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: SOUZA,JESUS R.D.; KAEFER,IGOR L.; LIMA,ALBERTINA P.
ABSTRACT Allobates subfolionidificans is a vulnerable and endemic leaf-litter frog from the state of Acre, Brazilian Amazonia. We monitored a population of A. subfolionidificans through regular censuses and mark-recapture of 181 individuals during an entire breeding season to characterize its reproductive behavior. The space use of A. subfolionidificans individuals differed between sexes, with males using smaller and more segregated spaces. Males defended territories and were aggressive against same-sex individuals, which was not the case in females. The daily cycle of calling activity showed peaks in the morning and in the afternoon, and the occurrence of reproductive events was positively correlated with monthly rainfall. The breeding behavior comprised...

Diet and nematode infection in Proceratoprhys boiei (Anura: Cycloramphidae) from two Atlantic rainforest remnants in Southeastern Brazil
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Klaion,Thaís; Almeida-gomes,Mauricio; Tavares,Luiz E. R.; Rocha,Carlos F. D.; Sluys,Monique Van.
Proceratophrys boiei is an endemic cycloramphid anuran inhabiting the leaf litter of Atlantic rainforests in Southeastern Brazil. We analyzed the whole digestive tract of 38 individuals of Proceratophrys boiei collected in two Atlantic Rainforest areas in the state of Rio de Janeiro, Brazil, to study the diet composition and the helminth fauna associated with this species. The main food items in P. boiei's diet were Coleoptera, Orthoptera and Blattaria. Five nematode species were found: Aplectana delirae, Cosmocerca parva, Oxyascaris oxyascaris, Physaloptera sp. (larval stage only) and an unidentified nematode. Overall prevalence was 71% and mean infection intensity was 7.3 ± 5.8 neatodes per individual.

Abstract Abstract: We used skeletochronology to compare age, size, reproductive parameters and growth patterns of two related, anuran amphibians from Northern Argentina: Leptodactylus bufonius(n=69) andL. latinasus(n=56), in order to better understand their coexistence in syntopy. Previous studies showed that the two species overlap in their dietary requirements and utilize the same habitats for feeding and breeding. We found that their life-history patterns are significantly different,L. bufoniusbeing larger, and having a higher reproductive output and lifespan, compared to the smaller and shorter-livingL. latinasus. Since none of the species exhibited sexual size dimorphism, and both acquired sexual maturity after the first year of life, we suggest that...

Seasonal testicular changes in Dendropsophus minutus Peters, 1872 (Anura, Hylidae)
Provedor de dados: Biocell
Autores: Ferreira,Adelina; Mehanna,Mahmoud.
The reproductive cycle in anurans may be either continuous or discontinuous. These differences may be connected to seasonal climate changes and/or to anthropic activity. Forty adult male individuals of the Dendropsophus minutus species were collected during one year, in the municipality of Chapada dos Guimarães (Mato Grosso, Brazil). The testicles were studied under light and transmission electron microscopy. No variations were observed when the diameter of the seminiferous tubules and the thickness of the interstitial tissue were studied. However, changes in spermatogenesis were conspicuous and indicated that the reproductive cycle of D. minutus in Chapada dos Guimarães is discontinuous and seems related to variations in air temperature and rainfall.

We investigated the NOR distribution in ten populations of Physalaemus cuvieri from different regions of Brazil and Argentina. A high variability in NOR pattern was observed and provided a useful tool in grouping several populations. The specimens from the state of Tocantins, northern Brazil, could easily be distinguished from all the other analyzed populations, since its karyotype presented NORs in the chromosome pairs 1,3,4 and 10 (and sometimes also in chromosome 5), and several pericentromeric C-bands. A NOR-site in chromosome 9 characterized three populations from the northeastern region of Brazil. Interestingly, the P. cuvieri populations located in opposite extremes of the geographic distribution had, as a fixed condition, the presence of NORs in 8q...

Abstract The Cerrado is one of the most threatened biomes in Brazil. It is estimated that much of its original vegetation has been replaced by some type of human use. This is quite worrying, mainly in the northern part where the number of wildlife inventories is insufficient and creates the false impression of low diversity in the region. The Parque Estadual do Mirador-PEM, located in the south-central region of the state of Maranhão, presents vegetation typical of the Cerrado biome and corresponds to one of 46 priority areas for conservation in the state. Herein, we describe the species richness and composition of the anurofauna from the PEM and analyze the influence of different types of vegetation in its formation.

A última lista de espécies do Estado de São Paulo foi atualizada, totalizando 236 espécies de anfíbios, das quais 230 são anuros e seis são Gymnophiona. Foram removidos da lista Bokermannohyla gouveai e Sphaenorhynchus surdus por não ocorrerem no Estado de São Paulo. O número de espécies de anuros registrado representa 27% da riqueza de espécies do país e um aumento de 31% em relação ao número de espécies registradas para o Estado em 1998, demonstrando que, a despeito do Estado de São Paulo ser a região brasileira onde os anuros foram mais estudados, o número de espécies conhecidas deve aumentar nos próximos anos. Foram evidenciadas duas lacunas geográficas importantes: a região sudoeste do Estado, principalmente na bacia hidrográfica do rio Paranapanema e...

Abstract: We provide an inventory checklist of the amphibians from Parque Nacional da Restinga de Jurubatiba (PNRJ), a sandy coastal environment in southeastern Brazil. As a result of three years of surveys, from August 2013 to June 2016, a total of 36 amphibians species were recorded - one Gymnophiona (Typhlonectidae) and 35 species of five anuran families: Bufonidae (2 species), Craugastoridae (1), Hylidae (21), Leptodactylidae (8), and Microhylidae (3). One specie is reported for the first time for the restinga ecosystem (Chthonerpeton braestrupi) and 24 species were recorded for the first time to the PNRJ. This result reinforces the importance of long-term studies for accurate knowledge of the biodiversity. Considering that the biodiversity of the...

Herpetofauna da área do Igarapé Esperança na Reserva Extrativista Riozinho da Liberdade, Acre - Brasil
Provedor de dados: Biota Neotropica
Autores: Bernarde,Paulo Sérgio; Machado,Reginaldo Assêncio; Turci,Luiz Carlos Batista.
A região do Alto Juruá localiza-se no estado do Acre (oeste da Amazônia brasileira) e é uma região conhecida por apresentar uma alta diversidade e também considerada prioritária para inventariamento e conservação da herpetofauna. Este trabalho foi realizado entre agosto de 2006 a junho de 2008 e apresenta a lista de espécies de anfíbios e répteis da área do Igarapé Esperança na Reserva Extrativista Riozinho da Liberdade, Acre. Quatro métodos amostrais foram empregados para inventariar a herpetofauna: procura limitada por tempo, armadilhas de interceptação e queda, registros auditivos e encontros ocasionais. Foram registradas 162 espécies, sendo 83 de anfíbios (80 anuros, dois gimnofionos e uma salamandra) e 79 de répteis (29 lagartos, 42 serpentes, um...

Anuran amphibians' diversity in a northwestern area of the Brazilian Pantanal
Provedor de dados: Biota Neotropica
Autores: Pansonato,André; Mott,Tamí; Strüssmann,Christine.
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...

Composição, riqueza e abundância de anuros em um remanescente de Cerrado e Mata Atlântica no estado de São Paulo
Provedor de dados: Biota Neotropica
Autores: Araujo,Cybele de Oliveira; Almeida-Santos,Selma Maria de.
Apesar da fauna de anuros no estado de São Paulo ser considerada a mais conhecida no país, ainda existem consideráveis lacunas amostrais no estado, sobretudo em remanescentes de vegetação natural das bacias hidrográficas do rio Paranapanema. Neste contexto, o objetivo deste estudo foi gerar informações sobre a composição, riqueza e abundância de anuros na Estação Ecológica de Angatuba, um remanescente de Cerrado e Mata Atlântica presente na bacia hidrográfica do Alto Paranapanema. O levantamento das espécies foi realizado em duas etapas de campo: março e novembro de 2007 e outubro de 2008 a março de 2009, totalizando 38 dias de inventário. A amostragem foi realizada por meio de armadilhas de interceptação e queda, encontro ocasional, procura auditiva e...

Vertebrados consumidos por Brycon opalinus (Pisces, Characidae) em rios do Parque Estadual da Serra do Mar, SP
Provedor de dados: Biota Neotropica
Autores: Gomiero,Leandro Muller; Briani,Denis Cristiano; Giasson,Luís Olímpio Menta.
A análise da alimentação da pirapitinga do sul (Brycon opalinus), peixe ameaçado de extinção de rios da Mata Atlântica da Serra do Mar na região Sudeste, revelou a ocorrência de itens alimentares incomuns. As espécies deste gênero são onívoras oportunistas e alimentam-se de itens vegetais e animais, tais como: flores, folhas, frutos e sementes e grande variedade de insetos. Em três rios do Parque Estadual da Serra do Mar - Núcleo Santa Virgínia foram encontrados exemplares de B. opalinus que consumiram três itens animais incomuns, os anfíbios Hypsiboas aff. pardalis (Anura, Hylidae) e Eleutherodactylus guentheri (Anura, Leptodactylidae) e o mamífero Oligoryzomys cf. nigripes (Rodentia, Sigmodontinae). O registro do consumo destas espécies de vertebrados...
