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 ...
Multimodal Duetting and Pair Formation in a Paleotropical False Leaf Katydid, Onomarchus uninotatus
The spectacular diversity in the pair-formation strategies among animal groups has attracted the attention of many over the years. The roots of this diversity lie in the diversity of challenges that males and females face ...
Foraging Decisions of the Lesser False Vampire Bat, Megaderma Spasma in a Heterogeneous Landscape
Predators make various foraging decisions at different spatial and temporal scales. Such decisions can be studied at two levels: patch decisions at the landscape level, and prey decisions at the foraging patch level. In ...
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 ...
Distribution, activity budget and feeding ecology of Himalayan gray langur (Semnopithecus ajax) in Kashmir Himalaya
Colobines are group of primates known to inhabit harsh environments. These habitats pose different challenges which they have coped up physiologically and behaviourally. Primates in such environments are subjected to ...
Systematics and Diversification in the Indian Radiation of Hemidactylus Geckos
Understanding the patterns and processes generating biodiversity is fundamental to ecology and evolutionary biology, and studying diversification can give us key insights into this process. In my thesis, I investigate ...
Systematics and Comparative Biogeography of Vine Snakes (Genus: Ahaetulla, Family: Colubridae) and Pit vipers (Genus: Trimeresurus, Family: Viperidae) in Peninsular India
The Indian subcontinent is a considered a mega biodiverse region with representative regions
belonging to three of the 35 global biodiversity hotspots, including the Western Ghats in
Peninsular India and the Eastern ...
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 ...
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 ...
