1976-81 University of Pennsylvania (Ph.D.)
1972-75 University of Chicago (B.A.)
I have broad interests in plant population and community ecology, including 35 years of research in Africa. For the last 20 years, I have been involved with more applied research at the community and landscape scales in California and Kenya. My current research projects are related to the ecology, management, restoration, and conservation of human-dominated landscapes.
My current research focuses on the following projects:
- Contingency in restoration ecology: priority effects, year effects, and site efferct (PRYER)
- Livestock and biodiversity in an African savanna (KLEE)
Secondary (and past) research includes:
- Planting issues in ecological restoration
- The maintenance of biodiversity in a model system (ACACIA)
- The evolution of semelparity
I also collaborate with my wife, Lynne Isbell, in her studies of primate behavioral ecology. I provide a life history and plant ecological perspective to her explorations of how food and predation influence the evolution of mammalian behavior. (Behavioral ecology publications).
UC Davis Spotlight article on the KLEE exclosure project
Satellite view of the KLEE exclosure plots in Laikipia, Kenya, where we have been excluding various combinations of cattle, wildlife, and mega-herbivores (elephants and giraffes) from a savanna grassland since 1995. Each of the 18 plots is 200m x 200m. This is an NDVI layer of an image taken 20 June 2003 (Quickbird, via Digital Globe). Lighter areas are indicative of higher productivity. The larger white areas are anthropogenic glades, and the smaller white areas are low termite "mounds". Both are hot spots of soil fertility, plant productivity, and animal use.
