We describe a new species of the endemic frog genus Nasikabatrachus,from the eastern slopes of the Western Ghats, in India. The new species is morphologically, acoustically and genetically distinct from N. sahyadrensis. Computed tomography scans of both species revealed diagnostic osteological differences, particularly in the vertebral column. Male advertisement call analysis also showed the two species to be distinct. A phenological difference in breeding season exists between the new species (which breeds during the northeast monsoon season; October to December), and its sister species (which breeds during the southwest monsoon; May to August). The new species shows 6 % genetic divergence (K2P) at mitochondrial 16S rRNA (1330 bp) partial gene from its congener, indicating clear differentiation within Nasikabatra- chus. Speciation within this fossorial lineage is hypothesized to have been caused by phenological shift in breeding during different monsoon seasons—the northeast monsoon in the new species versus southwest monsoon in N. -

Thank you to the many AmphibiaWeb apprentices over the last 21 years for their efforts. Edited by members of the AmphibiaWeb Steering Committee CC BY-NC-SA 2 Dedicated in loving memory of David B. Wake Founding Director of AmphibiaWeb (8 June 1936 - 29 April 2021) Dave Wake was a dedicated amphibian biologist who mentored and educated countless people. With the launch of AmphibiaWeb in 2000, Dave sought to bring the conservation science and basic fact-based biology of all amphibians to a single place where everyone could access the information freely. Until his last day, David remained a tirelessly dedicated scientist and ally of the amphibians of the world. 3 Table of Contents What are Amphibians?

From Clinging to Digging: The oP stembryonic Skeletal Ontogeny of the Indian Purple Frog, Nasikabatrachus sahyadrensis (Anura: Nasikabatrachidae) Abstract The ndI ian Purple frog, Nasikabatrachus sahyadrensis, occupies a basal phylogenetic position among neobatrachian anurans and has a very unusual life history. Tadpoles have a large ventral oral sucker, which they use to cling to rocks in torrents, whereas metamorphs possess adaptations for life underground. The developmental changes that underlie these shifts in ah bits and habitats, and especially the internal remodeling of the cranial and postcranial skeleton, are unknown. Using a nearly complete metamorphic series from free- living larva to metamorph, we describe the postembryonic skeletal ontogeny of this ancient and unique monotypic lineage. -

Feeding in Amphibians: Evolutionary Transformations and Phenotypic Diversity As Drivers of Feeding System Diversity
Chapter 12 Feeding in Amphibians: Evolutionary Transformations and Phenotypic Diversity as Drivers of Feeding System Diversity Anthony Herrel, James C. O’Reilly, Anne-Claire Fabre, Carla Bardua, Aurélien Lowie, Renaud Boistel and Stanislav N. Gorb Abstract Amphibians are different from most other tetrapods because they have a biphasic life cycle, with larval forms showing a dramatically different cranial anatomy and feeding strategy compared to adults. Amphibians with their exceptional diversity in habitats, lifestyles and reproductive modes are also excellent models for studying the evolutionary divergence in feeding systems. In the present chapter, we review the literature on amphibian feeding anatomy and function published since 2000. We also present some novel unpublished data on caecilian feeding biome- chanics. This review shows that over the past two decades important new insights in our understanding of amphibian feeding anatomy and function have been made possible, thanks to a better understanding of the phylogenetic relationships between taxa, analyses of development and the use of biomechanical modelling. In terms of functional analyses, important advances involve the temperature-dependent nature of tongue projection mechanisms and the plasticity exhibited by animals when switch- A.

Book of Barely Imagined for B 11/01/2013 10:17 Page i THE BOOK of BARELY IMAGINED BEINGS As centuries pass by, the mass of works grows endlessly, and one can foresee a time when it will be almost as difficult to educate oneself in a library, as in the universe, and almost as fast to seek a truth subsisting in nature, as lost among an immense number of books. Denis Diderot, Encyclopédie, 1755 In our gradually shrinking world, everyone is in need of all the others. We must look for man wherever we can find him. When on his way to Thebes Oedipus encountered the Sphinx, his answer to its riddle was: ‘Man’. That simple word destroyed the monster. We have many monsters to destroy. Let us think of the answer of Oedipus.
