BIOMS Seminar: Human consumer-resource dynamics

John Fryxell, Department of Intergative Biology, University of Guelph

There is growing awareness of the need for fishery and fur-bearer management policies that are robust to changing environmental, social, and economic pressures. Here I develop a set of models based on dynamic feedback among harvester effort, manager regulatory response, profitability, and resource abundance. These models are related back to time series data from a variety of fish and wildlife populations, suggesting that
non-equilibrium-based views of harvested populations may be the norm, rather than the exception, and predicting that potential for extreme resource variation should be factored into our long-term planning.
