In this unique and richly illustrated book, the reader will find information on the natural history of a wide tadpole' variety, of frogs, treefrogs and toads from all six Brazilian biomes. Starting with a basic description of the biology, collection methods and photographic recording, and the morphological characterization of tadpoles in general, i...

We studied the relationship between shape, size, and developmental time in the embryonic ontogeny of 15 species of the frog genus Physalaemus. As in other anuran exotrophic embryos, shape changes are correlated with size increase and mainly concern tail elongation, decrease in body height, and increase in fin height. Size ranges and developmental t...

A taxonomia é uma ferramenta importante para o conhecimento da biodiversidade local. Estudos taxonômicos com uma abordagem integrativa possibilitam um incremento das informações sobre o grupo foco do estudo, podendo auxiliar em iniciativas e estratégias de conservação para uma determinada área ou região. A região de Porto Seguro, Bahia, é inserida...

Abstract To understand the organism’s history, we can start assessing the complexity of the biome where they occur. In this study, we used a region of the mitochondrial genome, the rRNA 16S, to evaluate the genetic differentiation in Scinax nebulosus along with its geographical range highlighting important Brazilian biomes as Restinga, Cerrado, Ama...

We report a nest defensive behavior presented by a male Physalaemus atlanticus during the species' reproductive season. This is the first observation of active nest defensive behavior on genus Physalaemus. Future studies should explore how frequent this parental care behavior is displayed in this species and what the relavance of male defensive beh...

We describe the internal oral morphology and chondrocranial anatomy for Boana crepitans tadpoles, and compare them with available descriptions for other species in the subfamily Cophomantinae. Among species of the Boana faber group the chondrocranial anatomy has been reported only for one species Internal oral morphology and cranial anatomy are sim...

The nominal anuran species Crossodactylus gaudichaudii Duméril and Bibron, 1841 and Crossodactylus aeneus Müller, 1924 are indistinguishable based on adult and larval morphology, being subject of taxonomic doubts. Here, we describe the karyotypes of C. gaudichaudii and C. aeneus, using classical and molecular cytogenetic markers. In addition, we us...

The validation of many anuran species is based on a strictly descriptive, morphological analysis of a small number of specimens with a limited geographic distribution. The Scinax Wagler, 1830 genus is a controversial group with many doubtful taxa and taxonomic uncertainties, due a high number of cryptic species. One example is the pair of species S...

The external morphology, internal oral morphology, the chondrocranium and the hyobranchial apparatus of Elachistocleis bumbameuboi, E. cf. piauiensis, E. cesarii and E. bicolor are described and compared with each other and with other species of microhylids using available descriptions from the literature. The general morphology of Elachistocleis s...

The genus Phyllodytes comprises 15 species, ten of them having their tadpole external morphology described in the literature. However, there are few descriptive studies on chondrocranium and hyobranchial skeleton. In this work, we describe the chondrocranium and hyobranchial skeleton of Phyllodytes larvae and discuss shared features and interspecif...

Breeding anurans are commonly used for assessing biodiversity and identifying priority areas for conservation. Here we describe the diversity, composition, calling phenology, and habitat use of anuran species in a poorly known area of the Cerrado biome in the south-central portion of the state of Maranhão in northeastern Brazil, and examine the inf...

We describe the external morphology, internal oral anatomy, and chondrocranium of Pseudopaludicola canga. The tadpole is diagnosed by the following combined characters: elliptic body, reniform nostril, dorsal fin starting at the body-tail junction and labial tooth row formula 2(2)/2(1) presenting two lateral gaps in the marginal papillae of the low...

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 Estadua...

Corythomantis greeningi is a casque-headed frog that occurs in xeric and sub-humid regions of northeastern Brazil. Individuals are often found on rocks on banks of temporary streams or in ponds upon “lajedos”. Suctorial tadpoles are often found clasping to the rocks in the streams so as not to be dragged by the current; therefore, they have modifie...

Here, we document the sympatric occurrence of Pseudopaludicola canga and P. jaredi. We also provide the first record of P. jaredi in the state of Maranhão, northeastern Brazil, expanding this species’ distribution by about 610 km southwestward from Serra das Flores, municipality of Viçosa do Ceará, state of Ceará. Furthermore, we fill the gap in th...

Leptodactylus sertanejo is a mid-sized frog that inhabits areas of the Cerrado Biome, in natural and artificial grassland areas, in the states of Minas Gerais, São Paulo, Bahia, Goiás and Tocantins, Brazil. Herein, we provide the first species record for the state of Maranhão, northeastern Brazil, expanding the known distribution of L. sertanejo ca...

The Neotropical genus Adenomera Steindachner, 1867, belonging to subfamily Leptodactylinae (Pyron and Wiens, 2011), is widely distributed in South America east of the Andes and is currently represented by 18 species distributed in seven clade: A. andreae, A. heyeri, A. hylaedactyla, A. lutzi, A. marmorata, A. martinezi and A. thomei (Fouquet et al....

Presently, only 6 out of 14 species in the frog genus Crossodactylus have had their larvae described. Regarding internal oral morphology, only C. dispar, C. gaudichaudii, and C. trachystomus have had tadpoles described. Furthermore, the osteology of C. gaudichaudii was briefly studied and constitutes the unique reference to the subject within the g...

From the 86 species allocated in the genus Rhinella, 25 have their tadpoles described and only R. arenarum, R. chrysophora, R. icterica, R. ornata, R. schneideri and R. spinulosa have aspects of the internal oral morphology evidenced. Herein, the internal oral morphology from 12 species of Rhinella distributed between the morphological groups of R....

The taxonomic and phylogenetic relationships of the genus Phyllomedusa have been amply discussed. The marked morphological similarities among some species hamper the reliable identification of specimens and may often lead to their incorrect taxonomic classification on the sole basis of morphological traits. Phenotypic variation was observed among p...

From the 24 species allocated in the genus Hylodes, 16 have their tadpoles described, which five have information on the oral anatomy. Herein, the internal oral morphology of the tadpoles of H. dactylocinus, H. heyeri, H. aff. lateristrigatus, H. magalhaesi, H. meridionalis, H. phyllodes, H. sazimai, and H. uai is described, along with comparisons...

The genus Hylodes Fitzinger is composed of diurnal frogs that live associated to lotic streams in forests (Lingnau et al. 2008; Silva & Benmaman 2008). In Brazil, this genus occurs from the states of Espírito Santo to Rio Grande do Sul (Lingnau et al. 2008; Frost 2011). Hylodes currently comprises 24 species (Frost 2011) distributed in four species...

There are 45 species currently described for the genus Physalaemus that are allocated into seven morphological groups and 29 of them have their tadpoles described, of which 12 have information on their internal oral anatomy. In order to help resolving taxonomic and systematic problems, tadpoles from this genus had their external and internal oral m...

We report here the discovery of a new species of frog associated to the open areas of the highlands of the Parque Nacional da Serra dos Órgãos. The new species, Cycloramphus organensis is characterized by a unique skin texture, medium size (maximum male and female SVL 26.4 mm and 33.3 mm respectively), dorsal surfaces uniformly brick red colored, u...

The tadpoles of Physalaemus albifrons used in this description were obtained from a pair collected in a permanent pond in Brotas de Macaúbas, state of Bahia, Brazil. The external morphological features are similar to those of other members of the P. albifrons species group, differing by the presence of interruptions in the row of the marginal papil...
