Primary Area of Focus:
Primate Behavior and Socioecology
- Social Exchange and Cooperation – Aspects of Dr. Gumert’s research explores the role of dominance forces, kinship ties, and market effects on patterns of social exchange. Of greatest interest, is how short-term changes in demography affect the availability and demand for cooperative partners. This line of research is uncovering how biological markets act on primate social systems, with a major focus on identifying how individuals alter their behavior towards conspecifics based on the proximate social conditions surrounding them.
- Lithic Culture and Tool-use – Dr. Gumert is currently most involved in studying a population of long-tailed macaques in Thailand that customarily use stones to process and consume mollusks, crustaceans, and various types of nuts. Research on this population of macaques is currently identifying the diversity of food sources, usage styles and handgrips used with stones. Of particular interest is how the environment (i.e, stones chosen, habitats, and food types) and social learning affect these patterns. This work is also beginning to link into the field of Primate Archeology, which explores the Primate origins of lithic cultures and the basis of human technology.
- Human-Macaque Conflict – Long-tailed macaques have lived in close association to humans since pre-historic times. In the midst of the modern environmental collapse, conflict between humans and macaques across SE Asia appears to be increasing, which is creating new stressors on long-tailed macaque populations throughout the region. Dr. Gumert has been at the forefront of trying to understand the factors that lead to these wildlife conflicts and how such conflict impacts macaques and humans. Over the past few years, he has been trying to develop public discourse on strategies that can be used in Asia to humanely ameliorate human-macaque conflict and foster symbiotic human-macaque communities where possible.
