CIN Staff

In 2007, the CIN started with 25 principal investigators as cluster applicants, as stipulated in the DFG call for bids. When the CIN cluster was approved further  scientists from a range of institutions were incorporated, to make up the 48 'founding members' of the CIN. Since the beginning of 2014 the CIN has consisted of over 80 scientists in total. The membership process involves an application to the steering committee in which the candidate outlines his or her scientific profile and submits a list of publications. The committee's decision is based purely on the scientific excellence of each candidate.

Scientific topic: Echolocation in Bats

Field of Research

We investigate the echolocation behaviour of bats. Bats have to solve a multitude of different echolocation tasks depending on where they fly and forage, what they eat and how they acquire food. In the course of evolution bats evolved a repertoire of species-specific signals and behaviours that have been adapted to the echolocation tasks that have to be performed. In a tightly coupled action-perception loop echolocating bats continuously evaluate the incoming information, form an inner representation of the outside world and select the appropriate signals types and emission pattern to reach an intended behavioural goal. In this decision making process bats select from a set of options given by their species-specific repertoires of signal types that vary in frequency structure, duration and intensity, and of task specific sound patterns and scanning behaviours. We compare and analyze the echolocation behaviours of different species of bats at typical echolocation tasks to understand the decision making processes that lead to these behaviours and to conceive their adaptive value.
