Professor Rohini Balakrishnan of CES has been featured in the 'Conversation' section of the latest issue of Journal of Experimental Biology.

In an interview with Kathryn Knight, she describes her journey: how she became a bioacoustician and her experiences as a field biologist.


Acoustic Synchrony in Complex Calls

Synchrony between individuals or even non-living entities is one of the most striking natural phenomena: from clock pendulums that move in phase to fireflies that flash their light signals together and light up entire trees to crickets, katydids, cicadas and frogs that produce loud, synchronous acoustic choruses. The synchronising calls of species that have been hitherto investigated are however typically simple sound chirps or light flashes that are produced rhythmically at a particular rate.

Division of labour in a primitive insect society

Division of Labor

In most social insect colonies, a single individual, the queen, is privileged to produce offspring while the rest of the members, the workers, spend their entire lives working for the welfare of the colony and rear the queen's offspring. In addition to such reproductive division of labour between the queens and her workers, sub-sets of workers divide non-reproductive labour among themselves, such as working at home versus going out to obtain food, for example. How the members of a colony agree on and bring about an efficient and conflict-free division of labour is of great interest.

The scent of life: Phoretic nematodes use wasp volatiles and carbon dioxide to choose functional vehicles for dispersal.

Scent of Life

"Ever thought, "what is the scent of life?" and "can nematodes differentiate between different physiological states of their host?". To get answers and insights on the vehicle-passenger relationship do read this paper.


CES invites applications for Inclusive Ecology Workshop, Feb 2021 (Deadline 5th Feb)

Inclusive Ecology is an online workshop organised by the Centre for Ecological Sciences, Indian Institute of Science, Bengaluru. 

The workshop will introduce participants to broad concepts and approaches in the fields of Ecology, Evolution, Behaviour, Conservation and Quantitative Thinking via workshops. We will also conduct workshops on building professional skills, careers in ecology, and life as a PhD. student.
