Behavioural Ecology & Swarm Intelligence

Shoals of fish often achieve things that individual specimens are unable to do. It is easier for fish to find food, to recognise enemies quickly, and to reproduce more successfully in a shoal. In the case of humans, too, decisions taken collectively often turn out to be better than those made by individuals. For this reason, social networks and collective decision processes are not only interesting for ecology, but also for decision management in politics, medicine or the economy. In these systems, principles such as competition, organisation, cooperation and resource management play an important role. For this reason, at IGB we explore how decision processes can be improved. For example, we use knowledge of the swarm behaviour of fish to derive models for the dynamics and organisation of groups of people.

I will manipulate the social responsiveness of an interactive biomimetic robot (‘Robofish’) and quantify the following behavior of live guppies. This could provide empirical data to evaluate several recent theoretical models on collective motion and leadership in animal groups.
