Dr. Paul Caplat

I am interested in interactions: how individuals interact, making complex population dynamics arise, how local mechanisms interact to produce large-scale patterns, how large-scale patterns affect individuals, and how human societies interact with their environment. In practice, I have dealt mostly with woody plants dynamics, with or without interactions with farming activities: forest species migration under climate change, how mechanisms like re-sprouting or seed masting affect community dynamics, forest expansion with changes in grazing practices.

My favourite tool to approach these questions is individual-based modeling, which allows to simulate different situations with great flexibility. Combined with adequate statistical analysis or GIS utilities, it gives a good insight into ecological phenomena in space and time, for theoretical or applied studies.
