The [ecological] life and times of David Schimel
By: Steve HasstedtCaroline MelleHeather ScottKevin Wilcox
Education• BA in Biology and Applied Mathematics: 1977,
Hampshire College, Amherst, Massachusetts• Entry point into ecology was taking intro classes to be
better informed for general backpacking/camping trips– Drawn to the science of ecology, switched emphasis from
math/stats and came to CSU• PhD in Rangeland Ecosystem Science: 1982, Colorado
State University– Advisor: Dr. Bob Woodmansee– PhD Dissertation: The Effects of Hillslope Processes on Nutrient and Organic Matter Dynamics in a Shortgrass Steppe. 1982
Education & Professional Development• Key phrases/words: large scale
and international collaboration, increase the general knowledge, integration, synthesis
• Broad ecosystem based perspectives fostered here at CSU– International relationships developed
early– Working with Bob Woodmansee

ANALYSIS OF FACTORS CONTROLLING SOIL ORGANIC-MATTER LEVELS IN GREAT-PLAINS GRASSLANDS
Summary Information• Most cited publication: 1444 Citations• Schimel 2nd Author, Parton 1st Author• Published 1987 in Soil Society of America• Study done in the US Great Plains• Climatic and textural controls of SOC & N examined• Model of SOM quantity and composition and
productivity over climatic gradients• Regional trends of SOM based on temperature, moisture,
soil texture, and plant lignin• N inputs and grazing controls of SOM also considered
ANALYSIS OF FACTORS CONTROLLING SOIL ORGANIC-MATTER LEVELS IN GREAT-PLAINS GRASSLANDS
David Schimel’s Take: Why Cited So Often? • Many existing publications on controls of SOM at the
time, but 2 novel features of this publication:– First quantitative theory to explain amount &
distribution of soil C based on climate factors– First to incorporate both spatial and temporal
variability on large scales• Became the foundation for subsequent work by
explaining patterns of variability on regional scales• Schimel originally wanted to publish model based on
intensive sites, but was glad Parton won the argument to publish the model on regional scale

IPCC
• 1994 – 95:Convening lead author for chapters on Carbon cycling and impacts in North America
• Awarded Nobel Prize in 2007• Described experience as, “
fun, exciting, terrific” and that he was “doing research not assessment”
• The National Ecological Observatory Network (NEON) is, in Dr. Schimel’s opinion, “…an opportunity to fill the data deficit.”
• NEON will:– Collect data uniformly across the United States– Use large spatial and temporal scales to look at the impacts of:
• Climate change• Land use change• Invasive species on natural resources and biodiversity.
• Described by Science as, “The biggest project in the history of ecology… The Hubble telescope of ecology.” Data will be open source
• Dr. Schimel is doing, at NEON, a lot of “what [he] got into Ecology to avoid” (managerial work) because he believes strongly in what NEON is trying to achieve.
