Research in my lab integrates population ecology and ethnobiology to study plant-human interactions in a changing world and how this informs the conservation of biodiversity and sustainable use of ecosystem services. Understanding the feedback loop between human decision-making and plant population dynamics response is a critical first step into developing conservation through-use and sustainable harvest strategies for wild plants.
My research program includes two complementary areas. First, I use field observation and mathematical models to investigate the ecological and evolutionary impacts of anthropogenic activities on plants across habitats and climates. I ask how biotic and abiotic factors shape plant population dynamics, plant-insect interactions and mediate plant populations’ response to chronic anthropogenic disturbance (e.g., harvest, fire fragmentation, etc.). I then draw the direct implications for sustainable management. Second, I use an ethnoecological approach to investigate how local people use their ecological knowledge to understand the response of their environment to perturbation, global change, and accordingly adjust (or not) their management practices. This second aspect is designed to provide predictions on future harvesting patterns which in turn are fed into mathematical models to investigate how future harvest will impact existing forest resources. Answering these basic ecological and ethnoecological questions has direct implications for the conservation and sustainable use of plants.
I am actively recruiting new graduate students! If you are interested in plant population dynamics, demographic modeling, ethnoecology, and the study of (non)human impacts on plant demography and plant-insect interactions, send me an email or a tweet @ogaoue.
