Jon Keeley
Dr. Keeley is currently a research scientist with the U.S. Geological Survey, stationed at Sequoia National Park.
Prior to this appointment, he served one year in Washington, D.C. as director of the ecology program for the National Science Foundation. He was professor of biology at Occidental College for 20 years and spent a sabbatical year at the University of Cape Town, South Africa. He has more than 350 publications in national and international scientific journals and books. His research has focused on ecological impacts of wildfires as well as other aspects of plant ecology, including rare plants, rare habitats such as vernal pools, and plant physiology. In 1985 he was awarded a Guggenheim Fellowship and is a Fellow of the Ecological Society of America and an Honorary Lifetime Member of the California Botanical Society. He has served on the Los Angeles County Department of Regional Planning Environmental Review Board, and the State of California Natural Communities Conservation Program (NCCP) Board of Scientific Advisors.

No abstract available at this timeAuthorsJ. E. KeeleyRecruitment of seedlings and vegetative sprouts in unburned chaparral
Age structure of 12 stands of chaparral, unburned for 56—120 yr, was investigated. All shrubs produced discernible growth rings, and ring counts on stems from stands of known age, plus synchrony in annual growth ring width among species in the same stand, were taken as evidence that growth rings represented annual rings. Species that survive fire by vegetative regeneration from the root crown wereAuthorsJon E. KeeleyCommissioned Review. Carbon: freshwater plants
δ13C values for freshwater aquatic plant matter varies from −11 to −50‰ and is not a clear indicator of photosynthetic pathway as in terrestrial plants. Several factors affect δ13C of aquatic plant matter. These include: (1) The δ13C signature of the source carbon has been observed to range from +1‰ for HCO3− derived from limestone to −30‰ for CO2 derived from respiration. (2) Some plants assimilaAuthorsJ. E. Keeley, D.R. SandquistDemographic structure of California chaparral in the long-term absence of fire

Seasonal pools undergo marked diurnal changes in pH, free carbon dioxide, and oxygen levels. Previous studies showed that Isoetes howellii utilized crassulacean acid metabolism (CAM) photosynthesis as a means of assimilating carbon at night when ambient carbon dioxide levels are high. However, much of the pool flora is not CAM. We hypothesized that coexistence under extreme carbon—limiting conditiAuthorsJon E. Keeley, Darren R. SandquistThe relationship between stable oxygen and hydrogen isotope ratios of water in astomatal plants
Isotropic fractination of leaf water during transpiration is influenced by both equilibrium and kinetic factors. Previous workers have predicted that the influence of each factor varies depending upon the path of water loss,m whether centralized through stomata, or diffuse through the cuticle. We studied the relationship between the δD and δ18O values of lead and stem waters of laurel sumac, RhuAuthorsLee W. Cooper, Michael J. DeNiro, Jon E.
