Several features of the larval skeleton are of inter- est, including: absence of a cartilaginous strip between the cornua trabeculae, type of articulation of cornua and suprarostrals, presence of adrostral tissues, and the condition of the otic process. By com- paring sequence of ossification events across taxa, several patterns of skeletal development for Pelobates cultripes emerge, including: conserved timing of prootic ossification, delayed onset of mentomeckelian ossification, and early formation of vomerine teeth. Several other developmental features, including the absence of a palatine (= neopalatine) bone and the formation of the frontoparietal, also are discussed.

These Amphibia choices can strongly affect the resulting topologies. Here, we explore two controversial approaches (binning Anura genes into “supergenes” and inclusion of only rapidly evolving sites), using new data from hyloid frogs. Hyloid Biogeography frogs encompass ∼53% of frog species, including true toads (Bufonidae), glassfrogs (Centrolenidae), poison Naive binning frogs (Dendrobatidae), and treefrogs (Hylidae). Many hyloid families are well-established, but relationships Phylogenomics among these families have remained difficult to resolve. We generated a dataset of ultraconserved elements Statistical binning (UCEs) for 50 ingroup species, including 18 of 19 hyloid families and up to 2214 loci spanning > 800,000 aligned base pairs. -

Frog Eat Frog: Exploring Variables Influencing Anurophagy
Frog eat frog: exploring variables influencing anurophagy G. John Measey1, Giovanni Vimercati1, F. Andre´ de Villiers1, Mohlamatsane M. Mokhatla1, Sarah J. Davies1, Shelley Edwards1 and Res Altwegg2,3 1 Centre for Invasion Biology, Department of Botany & Zoology, Stellenbosch University, Stellenbosch, South Africa 2 Statistics in Ecology, Environment and Conservation, Department of Statistical Sciences, University of Cape Town, Rondebosch, Cape Town, South Africa 3 African Climate and Development Initiative, University of Cape Town, South Africa ABSTRACT Background. Frogs are generalist predators of a wide range of typically small prey items. But descriptions of dietary items regularly include other anurans, such that frogs are considered to be among the most important of anuran predators. However, the only existing hypothesis for the inclusion of anurans in the diet of post-metamorphic frogs postulates that it happens more often in bigger frogs. Moreover, this hypothesis has yet to be tested. Methods. We reviewed the literature on frog diet in order to test the size hypothesis and determine whether there are other putative explanations for anurans in the diet of post-metamorphic frogs. In addition to size, we recorded the habitat, the number of other sympatric anuran species, and whether or not the population was invasive. We controlled for taxonomic bias by including the superfamily in our analysis. Results. Around one fifth of the 355 records included anurans as dietary items of populations studied, suggesting that frogs eating anurans is not unusual. Our data showed a clear taxonomic bias with ranids and pipids having a higher proportion of anuran prey than other superfamilies. Accounting for this taxonomic bias, we found that size in addition to being invasive, local anuran diversity, and habitat produced a model that best fitted our data. -
Reversal to Air-Driven Sound Production Revealed by a Molecular
Irisarri et al. BMC Evolutionary Biology 2011, 11:114 http://www.biomedcentral.com/1471-2148/11/114 RESEARCHARTICLE Open Access Reversal to air-driven sound production revealed by a molecular phylogeny of tongueless frogs, family Pipidae Iker Irisarri1, Miguel Vences2*, Diego San Mauro3, Frank Glaw4 and Rafael Zardoya1 Abstract Background: Evolutionary novelties often appear by conferring completely new functions to pre-existing structures or by innovating the mechanism through which a particular function is performed. Sound production plays a central role in the behavior of frogs, which use their calls to delimit territories and attract mates. Therefore, frogs have evolved complex vocal structures capable of producing a wide variety of advertising sounds. It is generally acknowledged that most frogs call by moving an air column from the lungs through the glottis with the remarkable exception of the family Pipidae, whose members share a highly specialized sound production mechanism independent of air movement. Results: Here, we performed behavioral observations in the poorly known African pipid genus Pseudhymenochirus and document that the sound production in this aquatic frog is almost certainly air-driven. However, morphological comparisons revealed an indisputable pipid nature of Pseudhymenochirus larynx. To place this paradoxical pattern into an evolutionary framework, we reconstructed robust molecular phylogenies of pipids based on complete mitochondrial genomes and nine nuclear protein-coding genes that coincided in placing Pseudhymenochirus nested among other pipids. Conclusions: We conclude that although Pseudhymenochirus probably has evolved a reversal to the ancestral non- pipid condition of air-driven sound production, the mechanism through which it occurs is an evolutionary innovation based on the derived larynx of pipids. -

To unveil traces of expansion and contraction events of the species’ range, we sequenced 702 bp of the mitochondrial cytochrome b gene. To infer the population history we applied phylo- geographical methods, such as nested clade phylogeographical analysis (NCPA), and used summary statistics to analyse population structure under a neutral model of evolution. Popula- tions were assigned to different drainage systems and we tested hypotheses of explicit refugial models using information from analysis of molecular variance, nucleotide diversity, effective population size estimation, NCPA, mismatch distribution and Bayesian dating. -
Early Eocene Frogs from Vastan Lignite Mine, Gujarat, India
Early Eocene frogs from Vastan Lignite Mine, Gujarat, India ANNELISE FOLIE, RAJENDRA S. RANA, KENNETH D. ROSE, ASHOK SAHNI, KISHOR KUMAR, LACHHAM SINGH, and THIERRY SMITH Folie, A., Rana, R.S., Rose, K.D., Sahni, A., Kumar, K., Singh, L., and Smith, T. 2013. Early Eocene frogs from Vastan Lignite Mine, Gujarat, India. Acta Palaeontologica Polonica 58 (3): 511–524. The Ypresian Cambay Shale Formation of Vastan Lignite Mine in Gujarat, western India, has yielded a rich vertebrate fauna, including the earliest modern mammals of the Indian subcontinent. Here we describe its assemblage of four frogs, including two new genera and species, based on numerous, diverse and well−preserved ilia and vertebrae. An abundant frog, Eobarbourula delfinoi gen. and sp. nov., with a particular vertebral articulation similar to a zygosphene−zygantrum complex, represents the oldest record of the Bombinatoridae and might have been capable of displaying the Unken reflex. The large non−fossorial pelobatid Eopelobates, known from complete skeletons from the Eocene and Oligocene of Europe, is also identified at Vastan based on a single nearly complete ilium. An abundant “ranid” and a possible rhacophorid Indorana prasadi gen. and sp. nov. represent the earliest records of both families. The Vastan pelobatids and ranids confirm an early worldwide distribution of these families, and the bombinatorids and rhacophorids show possible origins of those clades on the Indian subcontinent.

Amphibian Diversity the Origin and Evolution of Amphibians
Amphibian Diversity The Origin and Evolution of Amphibians • The three living groups of amphibians are descended from a diverse group of tetrapods that first appeared in the Devonian Period, about 400 million years ago • The ancient continents were uniting into a single large landmass, Pangaea, much of which was situated in tropical or subtropical latitudes. • The climate is assumed to have been relatively warm and equable for terrestrial life. Land communities were characterized by assemblages of relatively primitive plants and arthropods. Phylogeny of Devonian tetrapods Phylogeny of Devonian tetrapods, with diagrammatic representations of skull structure of major clades. Ichthyostega is considered the sister group to the later tetrapods. The Origin of Modern Amphibians Alternative phylogenetic hypotheses for the relationships of lissamphibians, amniotes, and early tetrapods. (A)Traditional hypothesis showing lissamphibians related to temnospondyls. (B) Hypothesis of Laurin and Reisz (1997), showing lissamphibians related to lepospondyls and to microsaurs in particular. General Characteristics of Living Amphibians • Three major groups of amphibians are very different : 1. Frogs and toads (order Anura) : specialized for jumping, with greatly enlarged hind legs, shortened bodies, no tail, and large heads and eyes. 2. Salamanders and newts (order Urodela): more elongate, with front and back legs of approximately equal size and a long tail (this clade is called Caudata by some systematists, derived from the Latin rather than the Greek word for “tail”). 3. Caecilians (order Gymnophiona) : specialized for life underground. They have elongated, snakelike bodies that lack legs, and they have greatly reduced eyes.
