SIGNED: Christopher Izaak Roos 4 ACKNOWLDEGMENTS There are too many people to adequately thank in such a limited space. My grandparents, Jim, Betty, Gervaise, and Lillian; my mother, Darlene; her husband, Richard; my father, Mike; my mother-in-law, Kitti; and my brother, Jesse, never waivered in their confidence in me. I owe special thanks to my dad for his editorial expertise. At home, my two ladies, Kacy and Nina, did their best to keep me sane (or at least comfortably insane) during the dissertation process. My love and my partner, Kacy, has always been my biggest supporter. She encouraged me to explore the implications of my work beyond ecosystems and into the lives of people in the past and the present. Finally, I cannot thank you enough, Kacy, for your domestic fortitude while I wrote. This project would not have been possible without the financial and logistical support of a number of people and agencies. The Silver Creek Archaeological Research Project; Fred A. Reicker Research Fund; Emil W. Haury Scholarship Fund; University of Arizona (UA) AMS Research Facility; the UA Laboratory of Environmental Isotopes; the UA Palynology Laboratory; Statistical Research, Inc.; Apache-Sitgreaves National Forests; and the White Mountain Apache Tribe Heritage Program all provided sponsorship or financial support for portions of this research. The International Arid Lands Consortium (Grant #05R-09) provided major financial support for this project. A National Science Foundation Graduate Research Fellowship and an ACLS/Andrew Mellon Foundation Dissertation Completion Fellowship also supported me during the analysis and writing stages. Many of my peers, friends, and colleagues were extremely helpful in discussions, fieldwork, analysis, and interpretation. I owe special thanks to Bill Reitze, Nick Laluk, Susan Mentzer, James Mayer, Francesco Berna, Mitch Pavao-Zuckerman, Paul Goldberg, Rich Macphail, Ilit Cohen-Ofri, Steve Weiner, Owen Davis, Chris Eastoe, Greg Hodgins, Tim Jull, Jeff Homburg, Andrew Kowler, the Cube Room gang, Bill Longacre, Jeremy Haines, Carl Kantner, Heidi Stober, Tiina Manne, Jess Munson, Gary Huckleberry, Alan Sullivan, Daniela Triadan, and Scott Van Keuren. Without the assistance (and insistence) of John Welch, I would not have been able to pursue this research in the Forestdale Valley on the Fort Apache Indian Reservation. Mark Altaha, Doreen Gatewood, and Nick Laluk picked up where John left off after his move to Canada. I owe additional thanks to the White Mountain Apache Tribal Council, who officially supported the project with Resolution No. 05-2005-142. Finally, I could not have completed such a complex project without an expert committee. My co-chairs, Vance Holliday and Barbara Mills, ably guided me through the process, from proposal development to revisions. Mike Schiffer has been the only consistent member of every committee of my graduate career and has never failed to give me solid advice, edits, or criticisms. I benefited greatly from the experience of Jeff Dean who provided precise and thorough comments throughout the dissertation process. Tom Swetnam has demonstrated unmatched professionalism in his patience with an interloper and occasional heretic, such as myself, and guided me ably into the challenging realm of climate change research, humans and fire. To my entire committee, I hope that this dissertation reflects your guidance and support. Thank you all. 5 DEDICATION I dedicate this dissertation to the White Mountain Apache Tribe.
