The [ecological] life and times of David Schimel By: Steve Hasstedt Caroline Melle Heather Scott 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 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 Maintains contact & active collaboration with PhD advisor, faculty colleagues and students

ANALYSIS OF FACTORS CONTROLLING SOIL ORGANIC-MATTER LEVELS IN GREAT-PLAINS GRASSLANDS ANALYSIS OF FACTORS CONTROLLING SOIL ORGANIC-MATTER LEVELS IN GREAT-PLAINS GRASSLANDS Summary Information Most cited publication: 1444 Citations Schimel 2 nd Author, Parton 1 st 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 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.
