Diversity and distribution of mixed-species foraging groups in the Lakshadweep Islands, India
Species interactions are known to shape biological communities. While antagonistic interactions like competition and predation are well known, cooperative interactions have received comparatively less attention. Mixed-species ...
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 ...
Ecology of predator-prey interactions in the context of mate searching
Animals communicating in the context of mate searching benefit by increasing their
likelihood of encountering mates. Mate searching begins the important process of
individuals of opposite sexes forming pairs, which is ...
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, ...
Climate-Growth Relationships of West Himalayan Fir (Abies pindrow) along an Altitudinal Gradient in Northwestern Himalaya
Climate change which includes an increase in temperature, changes in precipitation, retreating of glaciers, has a significant impact on ecosystem dynamics and the social communities. High mountains around the globe are ...
Ground-dwelling arthropods across human land use: Interpreting the spatial and temporal dimensions of beta diversity
This study investigates beta diversity and its partitions to quantify the influence of different processes that drive spatial and temporal variation in ground-dwelling arthropod assemblages. First, ant assemblages across ...
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 ...
On Trait Evolution in a Heterogeneous Environment: Oviposition Site Selection in a Mosquito in Response to Multiple Risk Factors
A focus in evolutionary biology is to understand the drivers of diversity in animal behavioural traits in the living world. Animals facing similar problems in the environment, such as the problem of how much to invest in ...
Spatial and temporal patterns of vegetation- climate interactions
In this thesis, I tried to understand the patterns and processes of vegetation trends at different
spatial scales and resolution. The spatial variability in vegetation trends was related to inter and
intra-annual changes ...
Understanding Rules of Assembly and Species Interactions in Mixed-species Bird Flocks
In mixed-species bird flocks (flocks hereafter), participants vary in their degree of similarity
with each other. Flock participants can gain group size (supplementary) benefits by choosing
similar flock partners, or ...
