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.

The Long-Term Ecological Research (LTER) program facilitated my scientific growth in terms of the questions I can address; the tools, approaches, techniques and data to which I have access; and the diversity of intellectual and disciplinary expertise that I can tap. As a consequence, I am asking questions that cut across much larger spatial and especially temporal scales, and my research projects are more interdisciplinary, complex, and integrated. My ability to mentor students at all levels has been transformed by the variety of resources and opportunities afforded by the LTER program. One consequence is that these students are better prepared to become engaged globally. My role in the LTER program has required me to communicate scientific issues and findings to a broad audience. I have become more interested in the translation of science findings to public policy and practices to help conserve key functions of threatened ecosystems. My involvement with the LTER program has enabled me to forge a much larger circle of national and international collaborators to address questions that require a network of similar sites. The LTER construct has enabled me to broaden the scope of my research by expanding the interdisciplinary nature of my collaborations and the diversity of tools at my disposal. My involvement with the LTER program began in 2000 when I joined the Santa Barbara Coastal (SBC) site as an associate investigator, and it expanded in 2004 to include being the principal investigator of the newly established Moorea Coral Reef (MCR) site. I am privileged to continue to serve as principal investigator of MCR and as an associate investigator at SBC. My research interests center on ecological processes and feedbacks that drive the dynamics of populations and communities. Prior to my involvement in the LTER program, I conducted my research projects either alone or with a small group of like-minded collaborators to address such issues as regulation of (marine) animals with open populations or the effect of indirect interactions on coexistence of species (Figure 28.1). These projects taught me some of the limitations of “small science,” particularly when exacerbated by a lack of relevant long-term data.

Term Data

As a long-time member of the Long-Term Ecological Research (LTER) network, first as a graduate student and scientist at the Shortgrass Steppe (SGS) site (1984–1997), then as a scientist at the Sevilleta (SEV) site (1996–present) and now as principal investigator at the Jornada Basin (JRN) site (2003–present), my professional career has been shaped almost entirely by my LTER experiences. My experiences in the LTER program directly contributed to my individual-based approach to ecosystem dynamics combined with the knowledge that the dominant ecological processes can change as the spatial extent increases, and that long-term data are critical to disentangle how these pattern–process relationships change across scales. The LTER program has provided me with international experience and exposure that are valuable to my career. My opportunity to travel overseas has led to bonding experiences and new insights into other ecosystems. My appreciation for the value of K–12 education and the amount of work that is involved in “doing it right” has been shaped by my experiences with the Jornada Schoolyard LTER Program. One of the key challenges that I face in working at an LTER site is the tension between continuing to collect long-term observations with the need and desire to test new ideas that often result from the long-term data but then compete for resources with the collection of those data. Another challenge is in mentoring young scientists to become principal investigators, and in cultivating new relationships with potential co–principal investigators. Currently, I am the principal investigator at the JRN LTER program at New Mexico State University (NMSU) in Las Cruces, New Mexico. I am also a collaborating scientist at the SEV LTER program at the University of New Mexico in Albuquerque, New Mexico. I received my BS in biology at Iowa State University in 1981 and my MS in biology from San Diego State University (SDSU) in 1983. My LTER experiences began as a PhD student at Colorado State University (CSU) through the SGS LTER program in 1984, and these continued while I was a postdoctoral fellow (1988–1989).

I am a plant community and ecosystem ecologist who has conducted research within the context of the Long-Term Ecological Research (LTER) network from the beginning of my scientific career, now almost two decades ago. My research has benefited greatly from site-based research at the Konza Prairie (KNZ) LTER site, as well as from network-level syntheses utilizing data sets and knowledge produced by the collective of LTER sites. My involvement in the KNZ LTER site, in particular, has shown me the strength of conducting site-based research, yet my involvement in synthesis activities within the LTER network and beyond has illuminated the limitations of site-based research for addressing cross-site comparative research. To this end, I have been and continue to be a strong proponent of highly coordinated, multisite experiments, and much of my research is comparative in nature. Being involved in the LTER network from the start of my research career has made me a scientist who is well aware of the benefits and power of collaborative, multidisciplinary research. Because of the benefits and breadth of experiences that I have received from such research endeavors, I encourage my graduate students and postdoctoral fellows to also become involved in such research, and I recognize the positive impact collaborative, multidisciplinary research can have on beginning investigators. I believe that individuals outside of the LTER network (ranging from established principal investigators, to young investigators, to graduate students) are often not fully aware of the benefits of being involved in the LTER network or of the advances in ecological understanding that it has made possible. Thus, there is a need for the LTER network to be more proactive and creative in the ways that it attracts new researchers to get involved in the site-based or network-level research. Ultimately, the LTER network will only benefit from increased involvement by new investigators, who also could serve the role of leading the LTER network in the future. I have been affiliated with the LTER program since beginning as a graduate student at Kansas State University.

The Long-Term Ecological Research (LTER) program has enabled me to conduct more broadly relevant science by addressing questions within an interdisciplinary framework and to unravel the causes for surprising ecological phenomena through persistent studies and collaborations. Educational opportunities within the LTER program have connected me to students from grades K–12 to graduate levels in new ways from the field to the classroom, across places from Florida to Alaska, and among disciplines in a collaborative setting. The audience for my research expanded as a consequence of my experiences in the LTER program, and I have learned how to more effectively communicate integrative research to large audiences of scientists, policy-makers, and the public, often through nontraditional media. The LTER program is foremost a network of people, and I have found that science evolves most successfully when ideas and information are shared voluntarily across backgrounds, disciplines, and cultures in a network of cultivated, trusting relationships. The Florida Coastal Everglades (FCE) is the LTER site where I am currently the principal investigator, but the LTER program has been a part of my life for most of my career. My experiences in the LTER program began in the early 1990s when I was a graduate student at the University of Georgia, where the Coweeta (CWT) LTER site is based. Although I was not formally a part of CWT, many of my friends and professors were, so the program influenced my development as a scientist. I remember my first field trip to CWT, led by Gene Helfman and Judy Meyer, and the fun of snorkeling in mountain streams where we camped and conducted a few experiments, including examining the effects of rapid consumption of s’mores and boiled peanuts on preschool children (Judy and Gene’s kids). LTER-related activities wove in and out of my graduate student experience, and the rewards of sharing of ideas, data, friendships, and boiled peanuts created in me a lifelong commitment to persistent, collaborative science. This sense of fulfillment, of being part of something larger, was reinforced at the Savannah River Ecology Laboratory (SREL), where I conducted my research.

Set Up

I was committed to long-term, site-based, research long before the Arctic (ARC) Long-Term Ecological Research (LTER) site was established in 1987. Working with the LTER program since then has allowed me to reach my goals more easily than would have been possible otherwise. Because of my deep involvement in research in the LTER program, most of the examples I use in teaching now come from LTER sites. For the same reason, most of my communications with the public are about research in the LTER program. I learned the value of collaboration as a graduate student, from my earliest mentors and collaborators. Being a part of the LTER program has helped me to develop a wide array of enjoyable, comfortable, and productive collaborations. A message to students: be generous in all aspects of your research and professional life, because there is much more to be gained from generosity than there is to be lost. I helped set up the ARC site of the LTER program in 1987 and have made it the focus of my scientific career for the past 27 years. My experience with integrated, site-based, multidisciplinary ecosystem research actually began in 1972, however, when as a graduate student I worked with the US Tundra Biome Study at Barrow, Alaska (Brown et al. 1980; Hobbie 1980). The Tundra Biome Study and its umbrella organization, the International Biological Program (IBP), ended officially in 1974, but the ideas developed and lessons learned from these programs were central to the later development of the LTER program (Coleman 2010). These lessons were central to the formation of my own professional worldview; key among them was the idea that long-term approaches, including long-term, whole-ecosystem experiments, were essential to understanding distribution, regulation, and change in populations, communities, and ecosystems everywhere. My dissertation research, on root growth at the Barrow site, benefited greatly from the interactions I had with the diverse group who worked there. I finished my PhD in 1976, during a period when the need for a federally supported program of long-term, multidisciplinary, site-based ecological research was becoming increasingly clear.

The Tropics

The philosophy of research in the Long-Term Ecological Research (LTER) program expanded what I learned in graduate school from H. T. Odum by providing an approach for a holistic understanding of ecological processes in the tropics. Participation in the LTER program enabled collaborations with many talented people from many parts of the world and enabled the mentoring and education of a new cadre of tropical natural and social sciences students. By expanding the opportunities for research and analysis at larger scales, the LTER program allowed me to address tropical ecosystem responses to such phenomena as hurricanes, floods, landslides, and past land uses and to do so at the appropriate scales of time and space. Paradigms of tropical forest resilience and adaptability in the Anthropocene emerged from research at the Luquillo (LUQ) LTER site. I first became aware of the LTER program in 1978 as I walked by the White House in Washington, DC, with Sandra Brown, then an intern on the President’s Council on Environmental Quality (CEQ), and Wayne Swank, a US Forest Service employee on detail with the National Science Foundation (NSF). I was a staff member at CEQ, and W. Swank explained to us a new long-term ecological research program that he was helping develop at the NSF. Although the first cadre of sites appeared to have been selected, I was immediately captured by the concept and expressed my interest in developing a proposal for a tropical site in Puerto Rico. Little did I know at the time that my whole scientific career was about to change, in part because of the LTER program, but also because I was to become a US Forest Service scientist. The first 30 years of my US Forest Service career would be heavily influenced by the LTER program and the people I worked with while developing a new way of thinking about tropical forest ecosystems. I am an ecologist trained at the Universities of Puerto Rico and North Carolina at Chapel Hill. My experience before becoming part of the LTER program involved (1) teaching at the University of Florida at Gainesville and (2) government work at the Commonwealth (Puerto Rico Department of Natural Resources) and federal (President’s Council on Environmental Quality) levels.

The University

Environmental science has no room for theoretical or methodological hegemony, and questions cannot be asked in the absence of purposeful design. Education must simultaneously engage students in thinking and doing, ideally in collaboration. Communication is a two-way process in which scientists are challenged to be credible and legitimate in conveying salient results to diverse audiences. Collaboration is about leveraging individual skills toward a common purpose, which can only succeed when trust exists between investigators. I was trained as an ecological anthropologist with an emphasis on behavioral and ecosystem ecology at the University of Montana and the Pennsylvania State University. I have conducted archaeological, behavioral, cultural, and historical research throughout the western and the southeastern United States, as well as in several countries in lowland South America, the Dominican Republic, and southern France. Currently, I am professor and head of the Department of Anthropology at the University of Georgia. In 1997, I was invited to join the Long-Term Ecological Research (LTER) program at the Coweeta site (CWT). CWT is based in the eastern deciduous forest of the southern Appalachian Mountains, and I was brought in to collaborate on regionalization of what had been exclusively a site-based project. Just prior to joining CWT, I had been involved for several years in regional conservation activities in Paraguay and Bolivia. Since 2002, I have served as principal investigator of CWT, leading the successful grant renewal efforts in 2002 and 2008. I recently completed the 2014 renewal effort, which was successful. There has been a dramatic shift over the period of my involvement in the LTER program in attitudes within the network to regionalization and participation by scientists from disciplines other than ecology (Gragson and Grove 2006; Robertson et al. 2012). Several colleagues and I have helped to foster this shift through our involvement on the LTER Social Science Standing Committee (1998–present), leadership in the LTER planning activities (2004–2007), and service on the LTER Executive Board (2008–2011). My experiences in the LTER program have influenced my ideas about the nature and conduct of environmental research.
