Animals use different senses like vision, hearing, olfaction and touch to send and receive information about potential mates, food or predators. The accuracy and reliability of this information is not only dependent on the producers and receivers but also on the environment in which the information transfer takes place. I’m interested in understanding how the environment affects the production, transmission and perception of signals in arthropods. Specifically, I look at animals that use vibrations as one of their main sensory modalities. Vibratory signals are particularly interesting, because the environment in which these signals are produced and perceived, or in other words, the signal space, is often more limited than for other senses (i.e. think of an insect on a leaf vs. a bird in a forest). A smaller signal space makes the understanding of the effect of environmental complexity on information transfer more feasible. But, besides information transfer, I am also interested on the effects on the ecological interactions that are driven by these vibrational signals (i.e. predator-prey interactions, mating, finding food or conspecifics). How are these ecological interactions affected by variation in the environment, and how do they adapt to it?
