Intrinsic Noise in Collective Dynamics
Animal groups exhibit many emergent properties that are a consequence of local interactions.
Linking individual-level behaviour to group-level dynamics has been a question
of fundamental interest from both biological and ...
The influence of landscape composition on butterfly populations: A behavioural ecological approach
Overall, taking behavioural ecological and trait-based approaches, my study suggests that the distribution of a species and patterns in its population densities in a landscape are affected by diverse ecological variables, ...
Patterns and Drivers of Multimodal Signalling in Diurnal Geckos
Effective communication in animals comprise emission of a signal by a signaller and a response by a receiver, such that the interaction is beneficial to either only the signaller, or both the signaller and the receiver. ...
Through the looking glass: Phoresy as seen in the light of mutualism
Phoresy is the dispersal of small organisms on larger ones to move out of an unfavourable habitat. Although these interactions are transient, they can form tight links with mutualistic interactions if the phoretic organisms ...
Large Herbivore Dung Decomposition: Effects on Nutrient Cycling in a Tropical Forest of Southern India
Large herbivores can selectively feed on nutrient rich resources, resulting in regular deposition of high quality organic matter in the form of dung. In tropical forests such as in southern India it is estimated that large ...
Dispersal Patterns and Processes in Littorinid Snails along the Indian Coastline
Dispersal has important ecological and evolutionary consequences for a species. Marine dispersal is unique because of facilitation by ocean currents, where oceanography interacts with species traits and environmental ...
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. ...
A Phylogenetic Perspective on The Phytogeography of Western Ghats
I used a finer scale data of 156 published plots across the entire latitudinal range of WG, covering most of the protected
forests. The pruned phylogeny for this study consisted of 367 species, of which ~ 50% are taxa
endemic ...
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 ...
Local Interactions, Spatial Patterns and Ecosystem Stability
Many ecosystems exhibit striking patterns in the spatial distribution of organisms, for
example, patterns of clumping and dispersion in semi-arid vegetation, mussel in intertidal
beds and even sea-grass and macroalgae. ...
