Almost all living organisms on the earth perceive robust 24-hr cycles of abiotic variables such as light, humidity and temperature, which occur as an inevitable consequence of unceasing rotation of the earth around its ...

Neuronal circuits underline various simple and complex behaviours in animals, which are displayed in response to numerous stimuli in the environment. Drosophila melanogaster offers several simple but effective tools in ...

Organisms ranging from bacteria to mammals exhibit daily rhythms in various behavioural and physiological processes. These 24-hr rhythms are not mere passive responses to environmental cycles because they have been found ...

For my doctoral thesis, I have used a combination of experiments and simulations to investigate the various factors that affect the dynamics and stability of spatiallystructured as well as spatially unstructured populations. ...

Fitness can be comprehensively defined in terms of reproductive value or the expected future reproductive contribution of an individual, as a function of its age, expectation of survival and expectation of reproduction ...

Living organisms have evolved circadian clocks to time their physiological and behavioural activities to stay in tuned with the geophysical world. Signatures of such timing systems can be ...

In ant colonies a large proportion of individuals remain inside nests for most of their lives and come out only when necessary. It is not clear how, in a nest of several thousand individuals, information about local time ...

The fruit fly (Drosophila melanogaster) offers an extremely useful system to study circadian clock function at the behavioral, molecular, cellular, and organismal levels. We reared wild type (Oregon R+) and mutant flies – ...
