[cid:14dd8b73-a440-4822-b4c6-bdbbea3b8d43] Seminars in Hearing Research Date: August 28, 2025 Place: Nelson 1215 Time: Noon - 1:00 pm Speaker: Jeffrey Lucas               Title: Bats and signal complexity: sound and odor. Abstract: Given that bats live in the dark, communicating through sound and odor signals is particularly important. Also, a number of bat species have a polygynous, harem-based mating system. This makes territoriality critical to mating success and therefore makes territorial aggression common. I will cover a number of aspects of odor-based and sound-based communication used during aggressive interactions by the Himalayan leaf-nosed bat, including information encoded in both types of signals and selective factors that impact the evolution of signal complexity.
