A Forest to Prairie Transition as a Long-Term Ecological Research Scientist

Abstract

Being involved in the Long-Term Ecological Research (LTER) program for most of my career has greatly influenced my development as an ecologist. It has broadened my understanding and appreciation of ecological processes at scales ranging from microbial processes to ecosystem fluxes. Participating in the LTER program has heightened my awareness of the critical role of spatial and temporal variability in ecological dynamics, as well as the value of long-term data for identifying directional environmental changes or assessing responses to experimental manipulations. Working with other investigators at an LTER site over long periods of time has revealed the importance of a place-based understanding of ecological processes as a source of insight into complex ecological phenomena. Interacting and collaborating with students and scientists having diverse research interests and backgrounds has enhanced my ability to communicate more effectively with other scientists and with the public. There are some trade-offs between directing a large research program and advancing one’s personal research, but the rewards of long-term collaboration are substantial. I have been part of the LTER program for most of my career, from graduate student at one LTER site to principal investigator at another. I began my PhD training at the University of Georgia in 1983 under the direction of D.A. (Dac) Crossley, Jr., the first leader of the Coweeta (CWT) LTER program. My early research focused on forest ecology, including plant litter decomposition and effects of clear-cutting and regrowth on decomposer communities and forest floor processes (Blair and Crossley 1988). My first postdoctoral appointment was on a National Science Foundation (NSF) grant that I wrote to study forest-floor nitrogen dynamics using stable isotope tracers. In 1992, I joined the faculty of the Division of Biology at Kansas State University as an ecosystem ecologist. This position had been held by Tim Seastedt, another Crossley graduate student who served as principal investigator of the Konza Prairie LTER (KNZ) program and later as principal investigator of the Niwot Ridge LTER program. I was hired with the expectation that I would become engaged in the KNZ program, where my research would focus on ecosystem processes in tallgrass prairie.
