The 87th Annual Meeting of the American Association of Physical Anthropologists (2018)

Session 43. Advances in the Studies of the Communication Systems of Nocturnal Primates. Invited Poster Symposium. Chair: Sharon Gursky, Anna Nekaris Co-organizers: Anna Nekaris and Sharon Gursky

April 13, 2018 , Hill Country B-C Add to calendar

Auditory, visual and olfactory cues all play varying roles in nonhuman primate communication. Over the last decade, technological advances have allowed researchers to begin to conduct indepth investigations into the communication systems exhibited by the nocturnal and cathemeral prosimian primates, including tarsiers, lemurs and lorises. Understanding how nocturnal prosimians use visual, olfactory and auditory cues is vital for reconstructing the origins of primate communication systems. The goal of this symposium is to highlight some of the more exciting advances in the communication strategies of the prosimians. Individuals working in Kenya, Angola, Rwanda, Madagascar, and the Indonesian islands of Java and Sulawesi will be presenting their exciting new research on prosimian olfactory, visual and vocal communication. Topics will include the description of novel ultrasonic vocalizations, including frequency and function of these newly discovered calls; the possible use of vocalizations to navigate and assemble at sleep sites; the importance of species-specific contact vocalizations for the identification of new species; the use of urinary and glandular signals to communicate and the methods developed to understand this complex communication in the field; the use of vocalizations for niche separation among nocturnal primates from mainland African and Madagascar; novel methods to discern emotional state from vocalizations; and whether or not we can use new technologies to discern if prosimians use vocalizations for individual identification of group members. Discussion will be paneled by Nekaris and Gursky and focus on sharing of new field methods including equipment and techniques; best practice for analysis of vocal and olfactory data; new directions to pursue with a broad comparative approach within the strepsirrhines and tarsiiformes; the use of vocalization to influence conservation practices; and implications for the communication systems of our early primate ancestors.
