We present a comprehensive inventory of amphibians from Panna Tiger Reserve in Madhya Pradesh based on morphological, molecular and bioacoustic data. Representatives of 15 anuran species were collected, corresponding to roughly four fifths of the known amphibian species of Madhya Pradesh. The main results of this study are: (1) Description of advertisement calls of eleven species, including the first-time description of advertisement calls of Sphaerotheca pashchima. (2) Identification of cryptic species using acoustic and molecular techniques. (3) Five new significant range extensions and new state records. (4) Description of geographical variation in call properties in three anuran species. This study also provides morphological descriptions with ecological and natural history notes for each species that may be useful in management planning for amphibian conservation in Panna Tiger Reserve.
Old World tree frogs from the family Rhacophoridae, one of the most species-rich groups of amphibians worldwide, are becoming a model in ecological and evolutionary research, notably for their tremendous diversity of breeding systems. In this study, we provide the most comprehensive temporally and spatially explicit phylogeographical framework for the tropical neo-genus Zhangixalus, with a specific focus on the evolution of inter- and intraspecific polymorphism in their egg-laying strategies. We combined ~500 sequences spanning ~4 kb of mitochondrial genes, representative of nearly all known Zhangixalus species from 373 localities. We recovered a robust timetree featuring ~60 phylogeographical lineages assigned to 36 taxa, illustrating a vast under-appreciation of the diversity of the genus. Patterns of diversification were intimately linked to climatic trends since the Mid-Miocene, leading to a remarkable biogeographical scenario for the onset of Taiwanese diversity. Finally, in contrast to the macro-evolution of conserved breeding strategies in rhacophorids, the striking variation of nesting behaviour documented across Zhangixalus species, whereby foamy egg nests are alternatively fossorial, deposited on the edge of the water or suspended on the overhanging vegetation, seems to have evolved rapidly from arboreal ancestors in all major clades, implying micro-evolutionary processes and/or phenotypic plasticity.
Rashtrapati Bhavan Estates is a large semi-natural area comprising significant patches of secondary forest, cultivation, wetlands and parks in the heart of Delhi, the capital city of India. An inventory of herpetofauna was undertaken from May 15 to July 31, 2015, which revealed four species of amphibians and eight of reptiles. One reptilian species—Striped Keelback—was a new record for the Delhi region. In addition, secondary records of the presence of five snake species were obtained. Given the paucity of published data on natural history of the national capital, this annotated species checklist assumes importance and will be of use for urban planning and conservation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
