Human consumer-resource dynamics
Friday seminar by John M. Fryxell, University of Guelph, Canada
Most of the theory underlying sustainable harvesting is framed around static equilibrium conditions. Here I consider some of ways that harvest dynamics can arise through facultative changes in exploitation rates due to human social behavior, organizational behavior, and economic processes. All of these dynamical interactions can be represented reasonably well under a Lotka-Volterra framework. I will discuss several plausible examples of such behavior from wildlife and fish populations, as well as identifying key uncertainties that need resolution if we are to develop a truly useful theoretical framework for managing renewable natural resources.
