POLLEN DISPERSAL AND DEPOSITION IN THE HIGH-CENTRAL ANDES, SOUTH AMERICA A Dissertation Submitted to the Graduate Faculty of the Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Doctor of Philosophy in The Department of Geography and Anthropology by Carl A. Reese B.A., Louisiana State University, 1998 M.S., Louisiana State University, 2000 August 2003 Once again, To Bull and Sue ii ACKNOWLEDGMENTS First and foremost I would like to thank my major professor, Dr. Kam-biu Liu, for his undying support throughout my academic career. From sparking my initial interest in the science of biogeography, he has wisely led me through swamps and hurricanes, from the Amazon to the Atacama, and from sea level to the roof of the world with both patience and grace. I am who I am today because of him, and I want to sincerely thank him for that. I thank Dr. Robert Rohli for his support and advice throughout my doctoral program. He has not only been a great teacher and advisor to me, but has proved to be a true friend as well. I would also like to thank Drs. Steve Namikas, Nina Lam, and Laurie Anderson for serving on my committee and for their interest in this project. Dr. G. Bruce Williamson deserves special thanks not only for his guidance, but also for the seemingly hundreds of recommendation letters that he so kindly and carefully crafted for me. Thanks also to Mary Lee Eggart and Jason K. Blackburn for their cartographic assistance on this project. For his priceless help in the field, I thank Dr. Keith R. Mountain. The reason this dissertation exists is because of him and his hard work. At times I asked him to bear an unbearable load, and he never complained, and he never failed me. He is proof positive that, “No hill is too great for a climber”. I also want to further extend my gratitude to Dr. Lonnie G. Thompson for supplying me with not only research materials and data, but with the invaluable lessons that I have learned from him in the field. He is a world-class researcher, as well as a world-class human being. I am deeply indebted to the following for their financial support of this project; The National Science Foundation, The Association of American Geographers, The Geological iii Society of America, The Sigma-Xi National Research Society, The Department of Geography and Anthropology at Louisiana State University, and once again, Dr. Kam-biu Liu. Finally, I could not have done this without the support, encouragement, and love from my fiancée, Olivia Drinkwater. iv TABLE OF CONTENTS DEDICATION................................................................................................................................ ii ACKNOWLEDGEMENTS........................................................................................................... iii ABSTRACT.................................................................................................................................. vii CHAPTER 1.
