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...
Article
Unrelated species often evolve similar phenotypic solutions to the same environmental problem, a phenomenon known as convergent evolution. But how do these common traits arise? We address this question from a physiological perspective by assessing how convergence of an elaborate gestural display in frogs (foot-flagging) is linked to changes in the...

Amphibians show a high amount of species richness and endemism. Such diversity can be attributed to their microenvironment as amphibians display fine‐scale heterogeneity depending on the microhabitats they inhabit. Tadpoles are considered as good indicators for understanding microhabitat–species association as they reflect the breeding sites and si...
Article
Amphibians show a very high level of diversity and endemism and are facing global declines from the past few decades. Studies have shown that the molecular tools can be helpful in their conservation efforts. In India, more than 80% of amphibians are endemic and most show a narrow range of distribution. Most of the Indian amphibians lack information...

The genus Euphlyctis is widely distributed across Southwestern Arabian Peninsula into parts of Southeast Asia. Five of the seven known Euphlyctis species are found within the Indian subcontinent. Here, we describe a new species, Euphlyctis karaavali sp. nov. from South-west coast of India, which was discovered during surveys engaging citizens. This...

Microhyla sholigari is an endangered frog described in the year 2000. The original description was based on non-adult types and lacked information on several morphological characters, call structure, genetic material and photographs of the animal in life. The absence of such information posed challenges in field identification of this species. Sinc...

In recent times, several new species of amphibians have been described from India. Many of these discoveries are from biodiversity hotspots or from within protected areas. We undertook amphibian surveys in human dominated landscapes outside of protected areas in south western region of India between years 2013-2015. We encountered a new species of...

A new cryptic species of bush frog Raorchestes honnametti sp. nov. is described from the south-eastern part of the Western Ghats, India. This newly described species belongs to the Charius clade and is morphologically similar to other clade members—R. charius and R. griet. Therefore, an integrative taxonomic approach based on molecular and bioacous...

Western Ghats of India is known for its high amphibian diversity, but very little is known about their tadpoles. Here, for the first time, we describe tadpoles of three species of an endemic genus, Nyctibatrachus, namely N. kempholeyensis, N. jog and N. kumbara using morphology and molecular techniques. Tadpoles were found in the streams and Myrist...

Reproductive modes are diverse and unique in anurans. Selective pressures of evolution, ecology and environment are attributed to such diverse reproductive modes. Globally forty different reproductive modes in anurans have been described to date. The genus Nyctibatrachus has been recently revised and belongs to an ancient lineage of frog families i...

Nearly one-third of over 6600 species of amphibians worldwide is facing threat of extinction 1 , making them the most threatened vertebrate group on the planet 2. Populations of many species are declining rapidly, beyond the extinction rates that have occurred previously. Rapid urbanization leading to change in suitable habitat plays a major role i...

Questions (12)
Question
I am analyzing the influence of geography and river basin on gene-flow of an endemic frog. I am interested in performing dbRDA. I am using an individual based genetic matrix. I understand that we create Morgan Eigen Vector maps of geographic distance, but do we have to do the same for the response variable(Genetic matrix).
Question
I am working on understanding the genetic differentiation in populations of a stream frog . My results suggests: among groups variation 2%, within groups variation 15% and significant . within individual variation 83%. Can I get some suggestions on how to interpret this data.
Question
I converted my genepop file into BAPS file using CREATE. I have read the manual yet unable to understand how to proceed further. Any recommendations would be helpful.
Question
I am getting errors while running the program. 
Question
I am working on the landscape genetics of endemic frogs from India and want to analyse the effect of landscape variables on allelic richness. The software GESTE is helpful but the official link to download the software is not available
Question
I tried running the paramfile generated from TESS  in CLUMPP. The CLUMPP accepts the data and shows that  the software is running but I dont get any results.
Question
I am working on microsatellite data of two endemic amphibians from western ghats
Question
I am interested in understanding the effect of environment variables on frog species distribution.I have used PCA and my first and second components explain 9 and 4% variance. Is it useful or should I go for other test.My data do not show normal distribution
