Evolutionary processes leading to adaptive radiation regularly occur too fast to be accurately recorded in the fossil record but too slowly to be readily observed in living biota. The study of evolutionary radiations is thereby confronted with an epistemological gap between the timescales and approaches used by neontologists and paleontologists. Here we report on an ongoing radiation of extant ...

In the present study, anti-inflammatory and analgesic effect of aqueous extract of Ficus bengalensis (AEFB) and methanolic extract of F. bengalensis (MEFB) was evaluated in animal models. Preliminary results indicated that MEFB treatment possesses significant anti-inflammatory potential as compared to AEFB. The anti-inflammatory activity of MEFB exhibited in both acute (carrageenan induced hind...

In this study, the variation of aquatic molluscan diversity concerning seasonal water level fluctuations (WLF) and sediment texture was investigated in some perennial irrigation reservoirs associated head headwater streams Kala Oya river basin Sri Lanka. Altogether 11,752 specimens belonging to 10 gastropod taxa (96.6%) 2 bivalve (3.4%) were identified. Of these, 11,282 (96.0%) from reservoir s...

Phylogenetic relationships among snails (Caenogastropoda) are still unresolved, and many taxonomic categories remain non-monophyletic. Paraphyly has been reported within a large family of freshwater snails, Viviparidae, where the taxonomic status of several species remains questionable. As many endemic Chinese viviparid species have become endangered during the last few decades, this presents a...

Three new species of Kerria Targioni-Tozzetti from India, namely Kerria pennyae Ahmad & Ramamurthy sp. nov. on Schleichera oleosa from Orissa, Kerria dubeyi Ahmad & Ramamurthy sp. nov. on Ficus bengalensis from Bangalore and Kerria varshneyi Ahmad & Ramamurthy sp. nov. on Ziziphus mauritiana from Punjab are described and illustrated, and a key is provided to species of Kerria known from India.
