Non-random distribution of microsatellite motifs and (TTAGGG)n repeats in the monkey frog Pithecopus rusticus (Anura, Phyllomedusidae) karyotype
Provedor de dados: Genetics and Molecular Biology
Autores: Ernetti,Julia R.; Gazolla,Camilla B.; Recco-Pimentel,Shirlei M.; Luca,Elaine M.; Bruschi,Daniel P.
Abstract The monkey frog, Pithecopus rusticus (Anura, Phyllomedusidae) is endemic to the grasslands of the Araucarias Plateau, southern Brazil. This species is known only from a small population found at the type locality. Here, we analyzed for the first time the chromosomal organization of the repetitive sequences, including seven microsatellite repeats and telomeric sequences (TTAGGG)n in the karyotype of the species by Fluorescence in situ Hybridization. The dinucleotide motifs had a pattern of distribution clearly distinct from those of the tri- and tetranucleotides. The dinucleotide motifs are abundant and widely distributed in the chromosomes, located primarily in the subterminal regions. The tri- and tetranucleotides, by contrast, tend to be...

Tetraploidía en Ceratophrys (Anura, Leptodactylidae), análisis del registro fósil
Provedor de dados: Iheringia Série Zoologia
Autores: Mercadal de Barrio,Isabel T.; Barrio,Alfonso.
It has been confirmed the existence of the tetraploid counterpart of the genus Ceratophrys Wied, 1824 (extint at the present time) in Argentina and Brazil since the Pliocene, and the apparition of the octaploidy in the Upper Pleistocene - Holocene. Fossil material of the diploid form, distinctive of the Chacoan District, has been reported from the horizons of the Montehermosense Formation in south-east of the province of Buenos Aires, Argentina. The coexistence of diploid-tetraploid and tetraploid-octaploid forms in the same province was documented.

The tadpole of Hypsiboas atlanticus (Anura, Hylidae) from northeastern Brazil
Provedor de dados: Iheringia Série Zoologia
Autores: Nascimento,Filipe A. C. do; Lima,Marcelo G. de; Skuk,Gabriel O; Sá,Rafael O. de.
The tadpole of Hypsiboas atlanticus (Caramaschi &amp;amp; Velosa, 1996) is described from the municipality of Maceió, State of Alagoas, Brazil. At stage 36 the larvae have an overall elliptical body in lateral and dorsal views, oral disc anteroventral, spiracular tube sinistral, and labial tooth row formula 2(1,2)/3(1). The oral disc is surrounded, almost completely (anterior medial gap present) by a single row of marginal papillae. Described tadpoles of the H. punctatus species group can be differentiated by a combined disc oral features. Additional descriptions of H. punctatus (Schneider, 1799) tadpoles from populations throughout South America may be helpful in determining the status of these populations.

Diet of the South American frog Leptodactylus ocellatus (Anura, Leptodactylidae) in Uruguay
Provedor de dados: Iheringia Série Zoologia
Autores: Maneyro,Raúl; Naya,Daniel E.; Rosa,Inés da; Canavero,Andrés; Camargo,Arley.
The diet of Leptodactylus ocellatus (L., 1758) was studied in specimens collected at Maldonado Department (Uruguay), where monthly surveys were made between August 1998 and March 2000. A total of 143 frogs were collected, measured, sexed, and dissected, to assess stomach contents. The anurans were grouped into three age classes and four categories (considering sex and capture date). The trophic amplitude for each age class and sex-season category was quantified using Shannon-Weaver Index, and the trophic niche overlap between ages and categories by using the Pianka Index. Comparisons among treatments were made by G-tests. The most important prey items were coleopterans (IRI = 2547), and significant correlations were found between predator and prey sizes....

Advertisement call and female sexual cycle in Uruguayan populations of Physalaemus henselii (Anura, Leiuperidae)
Provedor de dados: Iheringia Série Zoologia
Autores: Maneyro,Raúl; Núñez,Diego; Borteiro,Claudio; Tedros,Marcelo; Kolenc,Francisco.
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...

Atividade reprodutiva de Physalaemus signifer (Anura, Leptodactylidae) em ambiente temporário
Provedor de dados: Iheringia Série Zoologia
Autores: Wogel,Henrique; Abrunhosa,Patrícia A.; Pombal Jr.,José P.
The breeding activity of Physalaemus signifer (Girard, 1853) was monitored from July 1999 to July 2000 in a temporary pond in Palmital, Municipality of Saquarema, State of Rio de Janeiro, Atlantic Rain Forest, Brazil. Males were sexually actives only in four nights, arriving at the pond on the early rainy season. Males in amplexus were larger and spent more nights in the reproductive aggregation than solitary ones. The number of nights was correlated with the mass of the males. Males adopted satellite behavior as alternative tactic for mate acquisition. Changes between calling and satellite tactics were observed in different nights. Calling males were not larger and heavier than satellite ones. Satellite behavior seemed to be related with the order of...

Autores: Rodrigues,Domingos de Jesus; Lopes,Frederico Santos; Uetanabaro,Masao.
The reproductive pattern of Elachistocleis bicolor (Guérin Méneville, 1838) was studied at Serra da Bodoquena, from October 2000 to September 2001. Reproduction occurred in the wet season (October to April) and was correlated to high continuous pluviometric precipitation. The species presents sexual size dimorphism, with females larger than males. The number of mature eggs per ovary was 620 ± 251 (n=39) and mature eggs measured 1.15 ± 0.30 mm (n=40). Elachistocleis bicolor presented significant relations between snout-vent length and number of mature eggs (n=39; r²=0.25; p=0.001), individual weight and number of mature eggs (n=41, r²=0.30; p=0.002), snout-vent length and ovarian weight (n=35; r²=0.47; p&lt;0.01), and individual weight and ovarian weight...

External Morphological Features of the Gills of Ichthyophis bannanicus Embryo (Amphibia, Gymnophiona)
Provedor de dados: International Journal of Morphology
Autores: Meng,Shaoquan; Bei,Yongjian; Li,Guifen; Lu,Ronghui; Qi,Baomin; Wu,Defeng.
The gills of Ichthyophis bannanicus have yet to be investigated. This paper describes the external morphological features of the gills of mature I. bannanicus embryos exhibiting three pairs of gills on their neck region. Each gill is composed of an axis and filaments. In newly released embryos, the filaments and the axis form at approximately 90° relative to each other; eventually, this angle decreases and the color of the gill fades. The filaments on the axis are arranged alternately, and their spacing varies. The mid-pair of gills is significantly longer by nearly twofold than the front and rear pairs. Likewise, the lengths of the front and rear pairs of gills are not significantly different (P &amp;gt;0.05); for the same pair of gills, the lengths of...

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...

Diversity, external morphology and ‘reverse taxonomy’ in the specialized tadpoles of Malagasy river bank frogs of the subgenus Ochthomantis (genus Mantidactylus)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Randrianiaina, R.-D.; Strauß, A.; Glos, J.; Glaw, F.; Vences, M.
We provide detailed morphological descriptions of the tadpoles of Malagasy river bank frogs of the subgenera Ochthomantis and Maitsomantis (genus Mantidactylus, family Mantellidae), and data on relative abundance and habitat preferences of Ochthomantis species from Ranomafana National Park in southeastern Madagascar. Our study includes the tadpoles of six described and four undescribed candidate species. Eight of these larvae were previously unknown. Tadpoles were identified by DNA barcoding. Due to the very rudimentary taxonomic knowledge on Ochthomantis, we followed a ‘reverse taxonomy’ approach in which adult classification was to a great part determined on the basis of larval differences. By this procedure we even identified one candidate species whose...

Autores: Biju, S.D.; Garg, S.; Mahony, S.; Wijayathilaka, N.; Senevirathne, G.; Meegaskumbura, M.
A systematic revision of the genus Hylarana in the Western Ghats-Sri Lanka biodiversity hotspot is presented. Species delineation in Hylarana is complicated due to a lack of distinct colour differences or striking morphological characters, leading to potential misidentification. We conducted extensive surveys throughout the Western Ghats-Sri Lanka biodiversity hotspot and performed multiple gene (16S, COI and Cytb) barcoding using 103 samples collected from cultivated land and natural habitats. Genetic distance comparisons and Neighbor Joining trees indicated the presence of at least 14 candidate species in the region, supported by taxa groupings for all three genetic markers. Utilising a combination of molecular and morphological data, we describe seven...

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: Vences, Miguel; Glaw, Frank; Andreone, Franco; Jesu, Riccardo; Schimmenti, Giovanni.
A revision of species included in the subgenus Laurentomantis (genus Mantidactylus) yielded new information about phylogeny, taxonomy, and biogeography of the endemic mantellid frog radiation in Madagascar. Four Laurentomantis species, distinguished by morphology and advertisement calls, are recognized: Mantidactylus (Laurentomantis) horridus (Northern and North- Western biogeographic regions), M. (L.) ventrimaculatus (South- East and East); M. (L.) malagasius (East); and the new species M. (L.) striatus (North-East). M. striatus and M. malagasius are probably sister species based on bioacoustic and morphological affinities. A tibial gland, so far unknown in anurans, is described in M. malagasius and M. horridus.

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...

Notes on the herpetofauna of Surinam : VI. Resurrection of Hyla ornatissima Noble (Amphibia, Hylidae) and remarks on related species of green tree frogs from the Guiana area
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hoogmoed, M.S.
In the present paper Hyla ornatissima Noble is removed from the synonymy of Hyla granosa Boulenger, and resurrected as a separate species on the basis of morphological, ecological and acoustical differences. Another relative of this group occurring in Guiana is Hyla sibleszi Rivero. Because of its superficial resemblance with these frogs Hyla punctata (Schneider), of another species-group, is also treated. All four species are extensively described, data on life history and distribution are given. H. sibleszi, so far only known from the type material and some associated specimens, is reported from several new localities in Venezuela and Guyana. It is suggested that the function of the intricate dorsal pattern of H. ornatissima serves to protect the animal...

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...

Annotated checklist of the herpetofauna of Petit Saut, Sinnamary River, French Guiana
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hoogmoed, M.S.; Avila-Pires, T.C.S.
The Mission Radeau des Cimes to Petit Saut, French Guiana, offered the opportunity to study the herpetofauna of the canopy of the tropical rainforest, an area hardly studied sofar. Two localities at heights of 30 and 35 m could be studied, whereas data on a third site were obtained through information from other participants. The herpetological results of the research in the canopy were meagre. Only the frog Hyla leucophyllata (Beireis) and the lizard Mabuya bistriata (Spix) were observed in the canopy. Additionally the terrestrial herpetofauna was studied extensively and turned out to contain some species that had not been reported before from French Guiana. Also, for many species new distribution data within French Guiana were obtained. Le Mission Radeau...

Morphological variation in two genetically distinct groups of the golden-striped salamander, Chioglossa lusitanica (Amphibia: Urodela)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Alexandrino, J.; Ferrand, N.; Arntzen, J.W.
Morphometric and colour pattern variation in the endemic Iberian salamander Chioglossa lusitanica is concordant with the genetic differentiation of two groups of populations separated by the Mondego river in Portugal. Salamanders from the south have shorter digits than those from the north. Clinal variation with a south to north increase in limb, toe and finger length was found superimposed on this dichotomy, resulting in stepped clines for characters describing appendage size. Genetic variability was paralleled by colour pattern variability in the contact zone and in northern populations. To explain the observed parallels we invoke the neutral processes of vicariant isolation, admixture in a secondary contact zone, genetic drift in addition to selection...

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.

Provedor de dados: Revista Brasileira de Zoologia
Autores: Miranda,Daniele B.; Albuquerque,Saymon de; Turci,Luiz Carlos B.; Bernarde,Paulo S.
In state of Acre, most anuran research has been carried out in areas of terra firme, whereas alluvial forests remain relatively unexplored. We document the richness, breeding environments and calling season of the anurans of the Lower Moa River in the Alto Juruá (state of Acre), a region considered to harbor high biodiversity. Sampling was conducted in two main areas with different forest typologies (Terra firme forest and Alluvial forest), totaling 256 ha. The diversity of anurans was analyzed using the Shannon-Wiener index, evenness and Berger - Parker dominance. The anurans were sampled from October 2008 to September 2009, using the following sampling methods: sampling at breeding sites, pitfall traps, time constrained visual search during the day...

Environmental heterogeneity: Anuran diversity in homogeneous environments
Provedor de dados: Revista Brasileira de Zoologia
Autores: Silva,Rodrigo Augusto; Martins,Itamar Alves; Rossa-Feres,Denise de C.
The northwestern region of São Paulo was extensively deforested during the agricultural expansion in the last century and only small fragments of the original vegetation cover remained. In this study, we investigated how habitat features influence the composition, richness, and diversity of anurans in environments homogenized by agricultural activities. We sampled monthly six breeding ponds located in pasture areas during twelve months. We recorded ten environmental descriptors for each breeding pond. We found 18 anuran species. The breeding ponds were structurally similar, but species composition differed among them. The environmental descriptors influence varies for each species, as demonstrated by the different associations between species and...

Advertisement call of Dendropsophus microps (Anura: Hylidae) from two populations from southeastern Brazil
Provedor de dados: Revista Brasileira de Zoologia
Autores: Forti,Lucas Rodriguez; Márquez,Rafael; Bertoluci,Jaime.
In anurans, acoustic communication is a major mechanism of pre-zygotic isolation, since it carries information about species recognition. Detailed descriptions of the acoustic properties of anuran advertisement calls provide important data to taxonomist and to the understanding of the evolution of the group. Herein we re-describe the advertisement call of the hylid frog Dendropsophus microps (Peters, 1872) after analyzing a larger sample than that of previous descriptions. We also compare the acoustic properties of the call in two populations and discuss the effect of the presence of the sister species, Dendropsophus giesleri (Mertens, 1950), a potential competitor, in one of the populations. Additionally, we provide information on calling sites and size...

Taxonomic status and redescription of Flectonotus ulei (Anura: Hemiphractidae), with a key for the species of Fritziana
Provedor de dados: Revista Brasileira de Zoologia
Autores: Folly,Manuella; Hepp,Fabio; Carvalho-e-Silva,Sergio P.; Duellman,William E.
Based on preserved specimens from the states of São Paulo and Rio de Janeiro, Flectonotus ulei Miranda-Ribeiro, 1926 is resurrected from its synonymy with Flectonotus fissilis (Miranda-Ribeiro, 1920) and is redescribed. Analysis of osteological characters and brood pouch structure confirms that F. ulei belongs to Fritziana. The species is small for the genus (snout-vent length in males, 19.2-26.9 mm, n = 2; in females, 20.3-21 mm, n = 4) and was found in bromeliads. Flectonotus ulei is characterized by dorsal pattern consisting of interorbital pentagon or hexagon-shaped mark delimited by heavy dark line, diameter of tympanum smaller than that of disc of third digit, and a brood pouch covering the eggs dorsally except for a narrow longitudinal slit; eggs...

Autores: Wei,Jie; Li,Yan-Yan; Wei,Li; Ding,Guo-Hua; Fan,Xiao-Li; Lin,Zhi-Hua.
ABSTRACT We compared the morphology of the erythrocytes of five anurans, two toad species - Bufo gargarizans (Cantor, 1842) and Duttaphrynus melanostictus (Schneider, 1799) and three frog species - Fejervarya limnocharis (Gravenhorst, 1829), Microhyla ornata (Duméril &amp; Bibron, 1841), and Rana zhenhaiensis (Ye, Fei &amp; Matsui, 1995). We then reconstructed the ancestral state of erythrocyte size (ES) and nuclear size (NS) in amphibians based on a molecular tree. Nine morphological traits of erythrocytes were all significantly different among the five species. The results of principal component analysis showed that the first component (49.1% of variance explained) had a high positive loading for erythrocyte length, nuclear length, NS and ratio of...

Feeding overlap in two sympatric species of Rhinella (Anura: Bufonidae) of the Atlantic Rain Forest
Provedor de dados: Zoologia
Autores: Sabagh,Leandro T.; Carvalho-e-Silva,Ana M. P. T.
A clear understanding of the relationships between overlapping, similarity, and competition is necessary to understand many of the questions about the structure and operation of a community. Rhinella icterica (Spix, 1824) and Rhinella crucifer (Wied Neuwied, 1821) are sympatric species of toads occurring in the National Park of Serra dos Órgãos in southeastern Brazil. The aim of the present study was to assess the dietary overlap of these two species. Ninety-four stomachs were analyzed, and 2245 prey items were found. Common prey were Hymenoptera, Coleoptera, Diptera, Lepidoptera larvae, Blattaria, Orthoptera, Hemiptera, Opiliones, and Aranaea. Ants were the most important prey in both diets, followed by beetles and cockroaches. The niche breadth of R....

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: Moreira,Glória; Barreto,Larissa.
The feeding ecology and the sazonal variation in capture frequencies of anurans in two localities of Central Brazil was studied. The anuran capture frequencies were analysed counting specimen numbers collected in pitfall traps during the dry and rainy seasons. Anurans were caught more frequently during the rainy season. The diet of adults Proceratophrys sp., Eleutherodactylus sp., Bufo paracnemis Lutz, 1925, and Physalaemus cuvieri Fitzinger, 1826 were studied through the analysis of individual stomach contents. Results showed that the type of diet varied among the species studied.

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.

ABSTRACT Herein, we report a new record of the milk frog Trachycephalus coriaceus for the Brazilian southern Amazonia and provide an updated geographic distribution map. We collected one specimen of T. coriaceus on 8 november 2016, during a nocturnal survey inside a dense ombrophilous forest in the right bank of the Teles Pires River, municipality ofJacareacanga, southern of Pará State. The record of T. coriaceus to Jacareacanga is the first to the State. The disjoint geographic distribution of this species along de Amazonia may just reflect the paucity of amphibian knowledge throughout this biome and the difficulty to detect this species in the field, given its explosive reproductive behavior.

A partially preserved lower jaw constitutes the holotype of Bageherpeton longignathus n. g., n. sp., a probable archegosaurid amphibian, which is here assigned to the Platyoposaurinae. The material was collected in the beds of the Rio do Rasto Formation outcropping in Rio Grande do Sul State, southern Brazil. This is the second archegosaurid described for the Permian of Brazil. Prionosuchus plummeri Price 1948, from the Pedra do Fogo Formation in the Parnaiba Basin (northeastern Brazil), is the first. The new taxon differs from other platyoposaurs by the presence of an extremely elongated precoronoid that participates in the mandibular symphysis.

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,...

Diversity and associations between coastal habitats and anurans in southernmost Brazil
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: OLIVEIRA,MAURO C.L.M.; SANTOS,MAURICIO B. DOS; LOEBMANN,DANIEL; HARTMAN,ALEXANDRE; TOZETTI,ALEXANDRO M.
This study aimed to verify the relationship between habitat and the composition of anuran species in dune and restinga habitats in southernmost Brazil. The habitats were sampled between April 2009 and March 2010 using pitfalls with drift fence. We have captured 13,508 individuals of 12 anuran species. Species richness was lower in the dunes and dominance was higher in the resting. Apparently the less complex plant cover, water availability, and wide daily thermal variation in dunes act as an environmental filter for frogs. This hypothesis is reinforced by the fact that the most abundant species (Physalaemus biligonigerus and Odonthoprynus maisuma) bury themselves in the sand, minimizing these environmental stresses. Despite being in the Pampa biome, the...

We studied the leaf-litter frog community of Estação Ecológica Estadual Paraíso, in Guapimirim, Rio de Janeiro State, southeastern Brazil. Herein we combined three sampling methods (large plots, visual encounter surveys and pit-fall traps) to present data on species composition, richness, relative abundance and densities. The local assemblage of frogs associated to the leaf-litter was composed by 14 species, belonging to nine families. Haddadus binotatus, a direct-developing frog, was the most abundant species in the community. The estimated density of the local leaf-litter frog assemblage based on plot sampling was 4.3 frogs/100 m². Haddadus binotatus had the highest density (1.1 ind/100 m²). Frogs were predominantly found at night. Thoropa miliaris had...

Morphologic and morphometric analysis of testis of Pseudis limellum (Cope, 1862) (Anura, Hylidae) during the reproductive cycle in the Pantanal, Brazil
Provedor de dados: Biocell
Autores: Ferreira,Adelina; Mehanna,Mahmoud; Prado,Cynthia P. A.
The spermatogenesis of Pseudis limellum, from the Southern Pantanal, Brazil, was studied from July 1995 to May 1996, through histological sections of the testis. The cells could be differentiated as: primary spermatogonia, large cells, generally with bilobed nucleus; secondary spermatogonia, smaller cells, with darker cytoplasm, chromatin of radial form; primary and secondary spermatocytes, differentiated according to the different stages of the nucleus during the successive cells divisions. Furthermore, we observed cells in process of morphologic differentiation: rounded spermatids much smaller, with nucleus containing chromatin in compacting process and cytoplasm reduction; elongated spermatids, generally parallel organized in well defined bundles, with...

Structure of the kidney of Bufo arenarum: Intermediate segment, distal tubule and collecting tubule
Provedor de dados: Biocell
Autores: Farías,Alejandro; Hermida,Gladys Noemí; Fiorito,Luisa Eleonora.
The ultrastructure of the intermediate segment (IS), distal tubule and collecting tubule (CT) of the south american toad Bufo arenarum, was studied by light and transmission electron microscopy. The IS is composed of cubical ciliated cells which propel the urine along the renal tubule. The distal tubule is divided into two portions: the early distal tubule (EDT) and the late distal tubule (LDT). The EDT is characterized by only one type of cells with well developed basolateral interdigitations and numerous elongated mitochondria, which are oriented normal to the basal surface. The "macula densa - like" is a specialized zone of the EDT in contact with the vascular pole, where cells are more tightly packed than in the rest of the tubule. The LDT shows two...

Autores: Laufer,Gabriel; Piñeiro-Guerra,Juan Manuel; Pereira-Garbero,Ramiro; Barreneche,Juan Manuel; Ferrero,Rosana.
Scinax aromothyella is a recently described hylid frog. Its distribution is not well known. There are records for Misiones, Argentina and for southeastern Uruguay. Here we report a new record of S. aromothyella from Aceguá, Cerro Largo Department, Uruguay (31° 53' 39" S and 54° 9' 17" W), based in tadpoles collected on the 15 of August, 2007. This new record extends the distribution of S. aromothyella in approximately 100 km north from previous reports in Uruguay. The samples were collected in a site located 2 km away from the border line with Brazil, reinforcing the idea that S. aromothyella might occur in Rio Grande do Sul.

Anurans of a riparian forest in Sao Carlos, state of Sao Paulo, Brazil
Provedor de dados: Biota Neotropica
Autores: Sabbag,Ariadne Fares; Zina,Juliana.
We surveyed anuran amphibians in a riparian forest fragment of the Córrego do Espraiado, located at the Universidade Federal de São Carlos, Municipality of São Carlos, state of São Paulo, southeastern Brazil. During March 2009 and February 2010 we did weekly surveys in which we recorded 13 anuran species. The species showed a seasonal reproductive activity. In addition, we found a positive correlation between the number of reproductively active species and photoperiod. We also found that the studied community was more similar to those of transitional areas between the Atlantic Forest and Cerrado than those of the nearby Cerrado fragments.

Anurans of the Parque Estadual do Mirador, a remnant of Cerrado in the state of Maranhão, Northeastern Brazil
Provedor de dados: Biota Neotropica
Autores: Andrade,Etielle Barroso de; Weber,Luiz Norberto; Leite,José Roberto de Souza Almeida.
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. Our inventory was conducted from...

In this study, we present some information of the regarding throphic niche from the anuran toad Rhinella icterica living in high altitudes above 2000 m a.s.l. from a habitat of the Atlantic Forest Biome - the Altitude Fields in the Itatiaia National Park. We found 150 prey items in toad stomachs, belonging to five prey types, as well as skin remains and some remains of plant material. The index of relative importance indicated that most important prey types were beetles and ants, these last composing 70% of the diet numerically and the trophic niche breadth (B) was 1.81. The relatively low diversity of prey types we recorded in the diet of R. icterica of Itatiaia and numerically dominated by ants suggests some preference for this item. We do not found...

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.

Amphibians and reptiles from a highly diverse area of the Caatinga domain: composition and conservation implications
Provedor de dados: Biota Neotropica
Autores: Loebmann,Daniel; Haddad,Célio Fernando Baptista.
We surveyed the herpetofauna from the Complex of Planalto da Ibiapaba (CPI), CE, Brazil, during two years, using five sampling methods and information available in the literature. The amphibians are represented by 38 species distributed into nine families. The reptiles found summed 84 species, distributed into 25 families. Most amphibians collected exhibited wide occurrence along CPI, where we recorded 24 species (63.2%), which occurred at least in 60% of the sampled environments. Reptiles showed a different pattern, since 52 species (62.6%) had a restricted distribution (up to two environments). Sixteen species out of 25 considered as rare in CPI are restricted to relict moist forests. We also applied a rarity-vulnerability index to determine the most...

Anurans of the sandy coastal plains of the Lagamar Paulista, state of São Paulo, Brazil
Provedor de dados: Biota Neotropica
Autores: Zina,Juliana; Prado,Cynthia Peralta de Almeida; Brasileiro,Cinthia Aguirre; Haddad,Célio Fernando Baptista.
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,...

Objectives of this study were to investigate the influence of low environmental temperature on the experimentally induced inflammatory response in post-metamorphic Rana catesbeiana (bullfrogs). To accomplish these goals, 120 specimens of Rana catesbeiana were kept at 6ºC and 24ºC, and treated by transfixion of thigh muscular tissue with a 5-0 suture or IM carrageenan injection. Results obtained through qualitative and quantitative evaluations showed that the lower environmental temperature significantly modulates the inflammatory process development. The animals in both models that were kept at 6ºC showed a significantly lower number of inflammatory cells in the lesion site than the one verified at 24ºC, apart from the evolution time. On the other hand,...

It is described a new species of treefrog of the genus Hyla, H. amicorum, from the Cerro Socopo, state of Falcón, western Venezuela. This new taxon can be differentiated from the congeners reported from Venezuela by the combination of characteristics as follow: small size (22.6 mm, in male), vestigial webbing between toes II and III, belly strongly areolated, skin dorsally smooth, vent covered totally by a skin fold, no pattern on dorsum, dentigerous processes of the vomer arranged forming a wide "U", located slightly behind and between the choanae. Intrageneric relationships of this new species are obscure, but a close relationships with those groups of H. minuta or H. microcephala groups would not be discarded, nevertheless as long as show unique...
