* CURRENT RESEARCH INTERESTS
Grasslands and savannas throughout the world appear to have
been replaced by shrub- and woodlands in recent history.
Documentation of these changes 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, dendro-chronology and stable isotope
chemistry to reconstruct vegetation history and to examine
potential, impending changes. 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
