Communication
Graduate students in the lab are studying various aspects of olfactory and acoustic communication in the spotted hyena. In her dissertation work, Kenna Lehmann is inquiring about the functional significance of several different hyena vocalizations, and also whether the whoop vocalizations produced by spotted hyenas have clan "signatures." The dissertation research of Kevin Theis inquired about what information is conveyed when hyenas engage in “pasting” behavior (see figure). His work also inquires about how the microbial fauna inhabiting a hyena’s paste glands affect the scent deposited by that individual when it pastes. In her dissertation research, Sarah Benson-Amram conducted a series of play-back experiments designed to inquire, among other things, about whether there are sex differences in what hyenas know about their social worlds (see also the brief description of our work on social cognition).
