Plants are able to exchange information with one another about herbivory and abiotic stress through scents. This research explores the ecological causes and consequences of information sharing among plants. In the past I worked with the study system of tall goldenrod (Solidago altissima) and showed how rapid evolution caused by herbivore removal altered the plant-plant communication. In the paper published in Current biology I together with the co-authors coined the mutual benefit hypothesis proposing an explanation to why communication offers a fitness benefit in adverse conditions (herbivory). I plant to continue work on the ecology of plant-plant communication with fireweed (Chamaenerion angustifolium) that has a similar life-history and ecological function as tall goldenrod.
