This paper examines the diversity of extant, nonhuman primate species. The majority of the course will be an exploration of the core topics in primate behaviour and ecology, including: diet and nutrition, predation, social structure, kinship, mating behaviour, social dominance, and cognition. Furthermore, primates live in communities with other species of animals, as well as a diverse array of plant life, and therefore must be considered as a part of a broader ecological system. We will explore the various interactions that primates have with these other species and the various roles that they play in the larger ecological community. In addition, we will examine the overarching threats to biodiversity, in general, and to primates in specific. Finally, we will seek to connect research in primatology to conservation action and explore of our own species' place in the natural world.
