"Turbulence as an olfactory communication line"

Antonio Celani (Institut Pasteur)

Sex pheromones provide arguably the most striking example of long-range communication through specialized airborne messengers. Most Lepidoptera are consistently attracted to calling females from distances up to several hundreds meters, reaching their partner in a few minutes. This feat is even more impressive upon realizing that females broadcast their pheromone message into a noise-ridden transmission medium, the turbulent atmospheric surface layer. Receiver males face the challenge of extracting information about the female’s location from a signal that is attenuated, garbled and mixed to other olfactory stimuli. Quantitative characterization of the statistics of airborne signals is therefore highly relevant for the understanding of the functional relationship between the physics of the environment shaping the olfactory stimulus and the biology of the insect responses. We address these questions by developing a theoretical framework that predicts the salient statistical properties of a tracer emitted by a localized source and transported by a turbulent flow.
