Evolutionary ecology of communication signals that induce aggregative behavior

Article Abstract:

Communication signals inducing aggregative behavior profoundly affect a variety of ecological interactions, partly because every member of the food web can exploit them. To develop an evolutionary argument for the use of signals inducing aggregative behavior in animals, the intricate role of aggregation pheromones in the ecology of Drosophila is discussed.
