With six feet on the ground – How insects sense vibrations Max Planck Institute for Chemical Ecology in Germany

Background:

There is increasing evidence that insects, such as bushcrickets (katydids) or ants, use vibratory signals for communication. This hidden information channel complements the other senses like hearing or smelling. There are many ways to send out vibratory signals, including drumming body parts, scraping mandibles or engaging a specialized stridulatory organ. There is limited knowledge about the sender and even less is known about the receiver side. With this project, we aim to investigate the sensory organ in the six legs of insects that is sensitive to airborne and substrate-born signals in bushcrickets and ants.

Project description:

We will investigate sensory organs in insect legs that are known to detect airborne and substrate-born vibrations. We will combine a broad spectrum of methodological approaches, starting from mechanical measurements of the stimulus-induced organ motion by optical measurements up to neurophysiological and functional imaging techniques. We aim at identifying the different mechano-sensors in the legs and bridge that to behavioral context through collaborating with the Yuko Ulrich lab.

Candidate profile:

We are looking for a highly motivated and creative candidate with a strong background in sensory biology, biomechanics and programming. Computational experiences and work with insects are highly recommended. A master’s degree in Biomechanics, Neuroethology or related discipline is required for this PhD position.
