Biogeography and comparative phylogeography of freshwater snails of India
Distribution of flora and fauna is shaped by both current and historical processes. In my thesis I concentrated on how the historical component of the governing processes have dictated the current distribution of biota. ... -
Condition-dependent signalling and mating behaviour in the tree cricket, Oecanthus henryi
Male reproductive success in systems exhibiting sexually selected traits can be driven by male mating effort in sexual signals and in the production of nuptial gifts. Male mating effort can be determined by various biotic ... -
Diversity from the Gut to Species: Phylogeny, Population genetics and Microbiome of the Antilope cervicapra
Evolutionary relationships between members of the Antilopina taxon have been much debated in recent years. The ‘true antelope’ clade is currently comprised of 4 genera viz., Gazella, Nanger, Eudorcas and the monotypic genus ... -
Dynamic colour change in Psammophilus dorsalis: role of natural and sexual selection
Overall, the results from this study support the idea that animal signals arise from a balance between increased conspicuousness for social signalling and inconspicuousness to avoid predation risk. Animals that can change ... -
Intrasexual competition in females of a socially polygynous lizard, Psammophilus dorsalis
Competition between individuals of the same sex, intrasexual competition, has received much attention in males, mainly because such competition, which is primarily for mates (i.e. sexual selection), often selects for ... -
Lineage delimitation and diversification in Nyctibatrachus, an endemic frog genus from the Western Ghats
Determining how biodiversity is produced and maintained remains one of the fundamental questions in ecology. The phenomenon of diversification, which occurs via the interplay of speciation and extinction, holds the key ... -
A place for everything and everything in its place: Spatial organization of wasps on the nests of the primitively eusocial paper wasp Ropalidia marginata
In my thesis, I found that queens and workers in the primitively eusocial paper wasp Ropalidia marginata use space on their nests non-randomly with a majority of individuals showing spatial fidelity to small core areas, ... -
Spatial and Coevolutionary Dynamics of Cooperation
Cooperation is ubiquitous across taxa in the animal kingdom. For example, microbes cooperate in producing antibiotic-resistant biofilms, mammals and birds collectively mob predators, and humans cooperate in utilization of ... -
Venomics of Medically Important yet Neglected Elapid Snakes of India and the Antivenomic Potential of Plant Extracts
India is considered the world's snakebite capital, where over 58,000 snakebite fatalities are registered annually. Most bites are primarily attributed to four snake species: the spectacled cobra (Naja naja), common krait ...
