There are many precedents for long-term research in the history of science. Long-Term Ecological Research (LTER) program’s current identity reflects significant change—intended and accidental, both consensual and conflictual—from research concerns that were prevalent in the 1980s. LTER program has pioneered modes of research organization and professional norms that are increasingly prominent in many areas of research and that belong to a significant transformation in the social relations of scientific research. The essays in this volume explore the impact of the LTER program, a generation after its founding, on both the practice of ecological science and the careers of scientists. The authors have applied the agenda of long- term scrutiny to their own careers as LTER researchers. They have recognized the LTER program as distinct, even perhaps unique, both in the ways that it creates knowledge and in the ways that it shapes careers. They have reflected on how they have taught (and were taught) in LTER settings, on how they interact with one another and with the public, and on how research in the LTER program has affected them “as persons.” A rationale for this volume is LTER’s distinctiveness. In many of the chapters, and in other general treatments of the LTER program, beginning with Callahan (1984), one finds a tone of defensiveness. Sometimes the concerns are explicit: authors (e.g., Stafford, Knapp, Lugo, Morris; Chapters 5, 22, 25, 33, respectively) bemoan colleagues who dismiss LTER as mere monitoring instead of serious science or who resent LTER’s independent funding stream. But more broadly, there is concern that various groups, ranging from other bioscientists to the public at large, may not appreciate the importance of long-term, site-specific environmental research. Accordingly, my hope here is to put LTER into several broader contexts. I do so in three ways. First, to mainstream LTER within the history of science, I show that the LTER program is not a new and odd way of doing science but rather exemplifies research agendas that have been recognized at least since the seventeenth century in the biosciences and beyond.
