Kevin 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 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
• Maintains contact & active
collaboration with PhD advisor,
faculty colleagues and students

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.
