The Max Planck Institute for Chemical Ecology is located on Beutenberg Campus in Jena, Germany. It was founded in March 1996 and is one of 80 institutes of the Max Planck Society (Max Planck Gesellschaft). Chemical ecology examines the role of chemical signals that mediate the interactions between plants, animals, and their environment, as well as the evolutionary and behavioral consequences of these interactions.
