Sustainable Food Systems at U-M
Ph.D., University of Michigan; Post Doc, University of Chicago; Faculty member at U-M since 1971.
I. Nonlinear dynamics, especially as applied to population models. Analytical and theoretical models of coupled predator/prey dynamical systems, applying analytical techniques similar to those used in coupled oscillators in physical systems. Application of complex one-dimensional maps to a variety of population and ecosystem concepts.
II. Dynamics of rain forest succession following catastrophic damage -- field work in Nicaragua in rain forest damaged by Hurricane Joan. This research is concentrated in ten permanent plots in the Atlantic Coast of Nicaragua in the area visited by Hurricane Joan in 1988. Annual censuses of all trees in these plots provide data for the analysis of post disturbance succession in this highly diverse tropical ecosystem.
III. Ecology of multidimensional agroecological systems -- intercropping systems and agroforestry systems in Tropical America, field work in Costa Rica, Nicaragua, and Mexico. The focus is on the role of biodiversity in the functioning of agroecosystems, especially the multispecies systems so common in tropical areas.
IV. Dynamics of rain forest destruction and conservation -- socioeconomic and political analysis of neotropical conversion. Focus is on recent events in Central America and the nature of the conversion process, including sociopolitical as well as ecological forces involved in current debates about rain forest conservation.
