Collins Graduate Teaching Assistant, Rangeland Ecosystem Science, Colorado State University Research Associate, Biology Department, Augustana College, Sioux Falls, SD CURRENT RESEARCH Grasslands and savannas throughout the world appear to have been replaced by shrub– and woodlands in recent history. This shift in vegetation structure has implications for the sustainability of pastoral and commercial livestock production systems and may influence climate and atmospheric chemistry via impacts on the carbon, nitrogen and water cycles. Documentation of shifts in woody plant abundance is poor and causes are not well understood. As a result, our ability to anticipate the rate, direction and magnitude of future changes is limited. My research has concentrated on interactions between grasses and woody plants in relation to soils, climate and disturbance. Population, transition probability and dynamic ecosystem simulation models are used in conjunction with remote sensing, GIS, dendrochronology and stable isotope chemistry to reconstruct vegetation history and to examine potential, impending changes and the consequences of such changes on sustainability of grazing systems, ecosystem biogeochemistry and land surface-atmosphere interactions. Field and laboratory experiments on the population biology of grasses and shrub growth forms are emphasized in the context of landscape ecology, succession and historical land–use practices.
