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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...
