Abstract
The frogs of genus Nyctibatrachus from the Western Ghats are endemic, with some taxa showing a narrow distribution range. Nyctibatrachus jog was known only from the type locality, Jog falls from Sharavathi river basin suggesting a restricted distribution. In this study, using DNA barcoding, we studied the distribution patterns of N. jog by sampling multiple river basins. 16S rRNA and Cytochrome b genes were used to distinguish N. jog from its congeners as well as to infer intra-species relationships. The results from the 16S rRNA gene showed 99% similarity of the collected individuals with the type specimen from Jog Falls confirming the identity of N. jog. The results indicate that N. jog has wide distribution extending its range in multiple river basins in the Western Ghats, India. This study also provides the Area of Occurrence and Extent of Occurrence of N. jog which could help in developing strategies for its conservation.

Abstract
The Western Ghats (WG) is an escarpment on the west coast of Peninsular India, housing one of the richest assemblages of frogs in the world, with three endemic families. Here, we report the discovery of a new ancient lineage from a high-elevation massif in the Wayanad Plateau of the southern WG. Phylogenetic analysis reveals that the lineage belongs to Natatanura and clusters with Nyctibatrachidae, a family endemic to the WG/Sri Lanka biodiversity hotspot. Based on geographic distribution, unique morphological traits, deep genetic divergence, and phylogenetic position that distinguishes the lineage from the two nyctibatrachid subfamilies Nyctibatrachinae Blommers-Schlösser, 1993 and Lankanectinae Dubois & Ohler, 2001, we erect a new subfamily Astrobatrachinae subfam. nov. (endemic to the WG, Peninsular India), and describe a new genus Astrobatrachus gen. nov. and species, Astrobatrachus kurichiyana sp. nov. The discovery of this species adds to the list of deeply divergent and monotypic or depauperate lineages with narrow geographic ranges in the southern massifs of the WG. The southern regions of the WG have long been considered geographic and climatic refugia, and this new relict lineage underscores their evolutionary significance. The small range of this species exclusively outside protected areas highlights the significance of reserve forest tracts in the WG in housing evolutionary novelty. This reinforces the need for intensive sampling to uncover new lineages and advance our understanding of the historical biogeography of this ancient landmass.

Abstract
The monotypic anuran family Ranixalidae is endemic to India, with a predominant distribution in the Western Ghats, a region that is home to several unique amphibian lineages. It is also one of the three ancient anuran families that diversified on the Indian landmass long before several larger radiations of extant frogs in this region. In recent years, ranixalids have been subjected to DNA barcoding and systematic studies. Nearly half of the presently recognized species in this family have been described over the last three years, along with recognition of a new genus to accommodate three previously known members. Our surveys in the Western Ghats further suggest the presence of undescribed diversity in this group, thereby increasing former diversity estimates. Based on rapid genetic identification using a mitochondrial gene, followed by phylogenetic analyses with an additional nuclear gene and detailed morphological studies including examination of museum specimens, new collections, and available literature, here we describe two new species belonging to the genus Indirana from the Western Ghats states of Karnataka and Kerala. We also provide new genetic and morphological data along with confirmed distribution records for all the species known prior to this study. This updated systematic revision of family Ranixalidae will facilitate future studies and provide vital information for conservation assessment of these relic frogs.

Abstract
Background Mitochondrial genomic (mitogenomic) reorganizations are rarely found in closely-related animals, yet drastic reorganizations have been found in the Ranoides frogs. The phylogenetic relationships of the three major ranoid taxa (Natatanura, Microhylidae, and Afrobatrachia) have been problematic, and mitogenomic information for afrobatrachians has not been available. Several molecular models for mitochondrial (mt) gene rearrangements have been proposed, but observational evidence has been insufficient to evaluate them. Furthermore, evolutionary trends in rearranged mt genes have not been well understood. To gain molecular and phylogenetic insights into these issues, we analyzed the mt genomes of four afrobatrachian species (Breviceps adspersus, Hemisus marmoratus, Hyperolius marmoratus, and Trichobatrachus robustus) and performed molecular phylogenetic analyses. Furthermore we searched for two evolutionary patterns expected in the rearranged mt genes of ranoids. Results Extensively reorganized mt genomes having many duplicated and rearranged genes were found in three of the four afrobatrachians analyzed. In fact, Breviceps has the largest known mt genome among vertebrates. Although the kinds of duplicated and rearranged genes differed among these species, a remarkable gene rearrangement pattern of non-tandemly copied genes situated within tandemly-copied regions was commonly found. Furthermore, the existence of concerted evolution was observed between non-neighboring copies of triplicated 12S and 16S ribosomal RNA regions. Conclusions Phylogenetic analyses based on mitogenomic data support a close relationship between Afrobatrachia and Microhylidae, with their estimated divergence 100 million years ago consistent with present-day endemism of afrobatrachians on the African continent. The afrobatrachian mt data supported the first tandem and second non-tandem duplication model for mt gene rearrangements and the recombination-based model for concerted evolution of duplicated mt regions. We also showed that specific nucleotide substitution and compositional patterns expected in duplicated and rearranged mt genes did not occur, suggesting no disadvantage in employing these genes for phylogenetic inference.

Abstract
Surveys of the amphibians (Order: Anura) of Ranomafana National Park, a midaltitude rainforest in central-eastern Madagascar, and nearby areas of disturbed habitats were carried out in two seasons (December 1991 and August 1992). A total of 40 frog species was recorded. In undisturbed areas many strictly terrestrial species were present, most of them belonging to the endemic family Mantellidae. These species showed changes in abundance between August and December, probably due to temperature variation. In contrast, most of the species found in altered habitats were arboreal or semiarboreal. These are ‘ecologically opportunistic’ species, not so sensitive to habitat variations and able to reproduce whenever conditions are favourable. These species were equally abundant in December and August and they appear to be able to live in a more varied habitat patchwork. To preserve the diversity and abundance of amphibians, nature reserves should retain a central core of primary forest to ensure the survival of the more specialized species, surrounded by a buffer zone of degraded vegetation to sustain the presence of more adaptable frog species.

Abstract
Ranidae is a large anuran group with a nearly cosmopolitan distribution. We investigated the phylogenetic relationships and early biogeographic history of ranid frogs, using 104 representatives of all subfamilies and families, sampled from throughout their distribution. Analyses of approximately 1570 bp of nuclear gene fragments (Rag-1, rhod, Tyr) and approximately 2100 bp of the mitochondrial genome (12S rRNA, tRNAVAL, 16S rRNA) indicate that the monophyly of several taxa can be rejected with high confidence. Our tree is characterized by a clear historical association of each major clade with one Gondwanan plate. This prevalence of continent-scale endemism suggests that plate tectonics has played a major role in the distribution of ranid frogs. We performed dispersal-vicariance analyses, as well as analyses constrained by paleogeographic data, to estimate ancestral distributions during early ranid diversification. Additionally, we used molecular clock analyses to evaluate whether these scenarios fit the temporal framework of continental breakup. Our analyses suggest that a scenario in which the ancestors of several clades (Rhacophorinae, Dicroglossinae, Raninae) reached Eurasia via the Indian subcontinent, and the ancestor of Ceratobatrachinae entered via the Australia-New Guinea plate, best fits the paleogeographic models and requires the fewest number of dispersal/vicariance events. However, several alternatives, in which part of the ranid fauna colonized Laurasia from Africa, are not significantly worse. Most importantly, all hypotheses make clear predictions as to where to expect key fossils and where to sample other living ranids, and thus constitute a strong basis for further research.

Abstract
We determined the complete nucleotide sequence of the mitochondrial (mt) genome of a Malagasy poison frog, Mantella madagascariensis (family Mantellidae), and partial sequences of two Mantella (M. baroni and M. bernhardi) and two additional mantellid species (Boophis madagascariensis and Mantidactylus cf. ulcerosus). The M. madagascariensis genome was shown to be the largest (23kbp) of all vertebrate mtDNAs investigated so far. Furthermore, the following unique features were revealed: (1) the positions of some genes and gene regions were rearranged compared to mitochondrial genomes typical for vertebrates and other anuran groups, (2) two distinct genes and a pseudogene corresponding to transfer RNA gene for methionine (tRNA-Met) were encoded, and (3) two control regions with very high sequence homology were present. These features were shared by the two other Mantella species but not the other mantellid species, indicating dynamic genome reorganization in a common ancestor linage before divergence of the Mantella genus. The reorganization pathway could be explained by a model of gene duplication and deletion. Duplication and deletion events also seem to have been responsible for concerted sequence evolution of the control regions in Mantella mt genomes. It is also suggested that the pseudo tRNA-Met gene sustained for a long time in Mantella mt genomes possibly functions as a punctuation marker for NADH dehydrogenase subunit (ND) 2 mRNA processing. Phylogenetic analyses employing a large sequence data set of mt genes supported the monophyly of Mantellidae and Rhacophoridae and other recent phylogenetic views for ranoid frogs. The resultant phylogenetic relationship also suggested parallel occurrence of two tRNA-Met genes, duplicated control regions, and ND5 gene translocation in independent ranoid lineages.

Abstract
In sub-Saharan Africa, amphibians are represented by a large number of endemic frog genera and species of incompletely clarified phylogenetic relationships. This applies especially to African frogs of the family Ranidae. We provide a molecular phylogenetic hypothesis for ranids, including 11 of the 12 African endemic genera. Analysis of nuclear (rag-1, rag-2, and rhodopsin genes) and mitochondrial markers (12S and 16S ribosomal RNA genes) provide evidence for an endemic clade of African genera of high morphological and ecological diversity thus far assigned to up to five different subfamilies: Afrana, Cacosternum, Natalobatrachus, Pyxicephalus, Strongylopus, and Tomopterna. This clade has its highest species diversity in southern Africa, suggesting a possible biogeographic connection with the Cape Floral Region. Bayesian estimates of divergence times place the initial diversification of the southern African ranid clade at approximately 62-85 million years ago, concurrent with the onset of the radiation of Afrotherian mammals. These and other African ranids (Conraua, Petropedetes, Phrynobatrachus, and Ptychadena) are placed basally within the Ranoidae with respect to the Eurasian groups, which suggests an African origin for this whole epifamily.

Abstract
The geological history of the Indian subcontinent is marked by successive episodes of extensive isolation, which have provided ideal settings for the development of a unique floral and faunal diversity. By molecular phylogenetic analysis of a large set of ranid frog taxa from the Oriental realm, we show that four genera, now restricted to torrential habitats in the Western Ghats of India and the central highlands of Sri Lanka, represent remnants of ancient divergences. None of three other biodiversity hotspots in the Oriental mainland were found to harbour an equivalent level of long-term evolutionary history in this frog group. By unceasingly providing favourable humid conditions, the subcontinent's southern mountain ranges have served as refugia for old lineages, and hence constitute a unique reservoir of ancient ranid endemism.

Abstract
The 21st century will be that of the crisis of biodiversity and of extinctions: a majority of the planet's species might disappear before having even been studied by man. The discipline in charge of this study, taxonomy, is currently facing severe problems, concerning its status inside biology and its relationships with conservation biology. Yet taxonomy and conservation biology would have much to gain to becoming allies rather than largely foreign disciplines. This would require some important changes in mentality and behaviour.

Abstract
Using characters from mitochondrial DNA to construct maximum parsimony and maximum likelihood trees, we performed a phylogenetic analysis on representative species of 14 genera: 12 that belong to the treefrog family Rhacophoridae and two, Amolops and Rana, that are not rhacophorids. Our results support a phylogenetic hypothesis that depicts a monophyletic family Rhacophoridae. In this family, the Malagasy genera Aglyptodactylus, Boophis, Mantella, and Mantidactylus form a well-supported sister clade to all other rhacophorid genera, and Mantella is the sister taxon to Mantidactylus. Within the Asian/African genera, the genus Buergeria forms a well-supported clade of four species. The genera, except for Chirixalus, are generally monophyletic. An exception to this is that Polypedates dennysii clusters with species of Rhacophorus, suggesting that the taxonomy of the rhacophorids should be revised to reflect this relationship. Chirixalus is not monophyletic. Unexpectedly, there is strong support for Chirixalus doriae from Southeast Asia forming a clade with species of the African genus Chiromantis, suggesting that Chiromantis dispersed to Africa from Asia. Also, there is strong support for the sister taxon relationship of Chirixalus eiffingeri and Chirixalus idiootocus apart from other congeners.

Abstract
Most examples of intercontinental dispersal events after the Miocene contact between Africa and Asia involve mammal lineages. Among amphibians, a number of probably related groups are known from both continents, but their phylogenies are so far largely unresolved. To test the hypothesis of Miocene dispersal against a Mesozoic vicariance scenario in the context of Gondwana fragmentation, we analyzed fragments of the mitochondrial 16S rRNA gene (572 bp) in 40 specimens of 34 species of the anuran family Ranidae. Results corroborated the monophyly of tiger frogs (genus Hoplobatrachus), a genus with representatives in Africa and Asia. The African H. occipitalis was the sister group of the Asian H. crassus, H. chinensis, and H. tigerinus. Hoplobatrachus was placed in a clade also containing the Asian genera Euphlyctis and Nannophrys. Combined analysis of sequences of 16S and 12S rRNA genes (total 903 bp) in a reduced set of taxa corroborated the monophyly of the lineage containing these three genera and identified the Asian genus Fejervarya as its possible sister group. The fact that the African H. occipitalis is nested within an otherwise exclusively Asian clade indicates its probable Oriental origin. Rough molecular clock estimates did not contradict the assumption that the dispersal event took place in the Miocene. Our data further identified a similar molecular divergence between closely related Asian and African species of Rana (belonging to the section Hylarana), indicating that Neogene intercontinental dispersal also may have taken place in this group and possibly in rhacophorid treefrogs.

Abstract
Recent studies have reported that independent adaptive radiations can lead to identical ecomorphs. Our phylogenetic analyses of nuclear and mitochondrial DNA sequences here indicate that a major radiation of ranid frogs on Madagascar produced morphological, physiological, and developmental characters that are remarkably similar to those that independently evolved on the Indian subcontinent. We demonstrate further that, in several cases, adult and larval stages each evolved sets of characters which are not only convergent between independent lineages, but also allowed both developmental stages to invade the same adaptive zone. It is likely that such covariations are produced by similar selective pressures on independent larval and adult characters rather than by genetic or functional linkage. We briefly discuss why larval/adult covariations might constitute an important evolutionary phenomenon in species for which more than one developmental stage potentially has access to multiple environmental conditions.

Abstract
An analysis of partial sequences of the 16S ribosomal rRNA gene (582 bp) of 20 poison frog species (Dendrobatidae) confirmed their phylogenetic relationships to bufonid and leptodactylid frogs. Representatives of the ranoid families and subfamilies Raninae, Mantellinae, Petropedetinae, Cacosterninae, Arthroleptidae, Astylosternidae, and Microhylidae did not cluster as sister group of the Dendrobatidae. Similar results were obtained in an analysis using a partial sequence of the 12S gene (350 bp) in a reduced set of taxa and in a combined analysis. Within the Dendrobatidae, our data supported monophyly of the genus Phyllobates but indicated paraphyly of Epipedobates and Colostethus. Minyobates clustered within Dendrobates, contradicting its previously assumed phylogenetic position. Phobobates species clustered as a monophyletic unit within Epipedobates. Allobates was positioned in a group containing two Colostethus species, indicating that lack of amplexus, presence of skin alkaloids, and aposematic coloration evolved independently in Allobates and the remaining aposematic dendrobatids.
