SCRATCHING THE SURFACE: A CONTENT ANALYSIS OF GORILLAS AS ZOOGEOMORPHIC AGENTS by Andrea E. Piñon, B.S. A thesis submitted to the Graduate Council of Texas State University in partial fulfillment of the requirements for the degree of Master of Science with a Major in Geography August 2018 Committee Members: David R. Butler, Chair Jennifer Jensen Richard Dixon COPYRIGHT by Andrea E.

Butler, for his invaluable input and guidance on improving the quality of this thesis. From the day I stepped into my first geography class as an undergraduate student; his intellect and wit has nurtured an insatiable love and appreciation for geography. His exemplary scholarship accompanied with his discernable passion for teaching will continue to serve as a model as I reach for my future professional and research goals. Dr. Butler’s edits, comments, and suggestions were both ingenious, and were often presented in a manner that was comical, giving me much needed relief during the editing process. I am incredibly appreciative of the many times I found myself laughing out loud at his insightful, yet, humorous comments on my thesis drafts. I would also like to thank my committee members, Dr. Richard Dixon and Dr. Jennifer Jensen. Dr. Dixon’s input and keen “wordsmithing” skills have contributed to my growth as a writer. Dr. Jensen’s continued commitment to meet with me to explain anything on geographic information systems and support through the learning process has been invaluable. I would also like to thank the Terry Foundation for their financial support during my undergraduate career and first year as a graduate student developing this project. Their monetary gift has allowed me to achieve goals that I never imagined. The foundation has changed my life, my family’s lives, and the lives of my future children by providing me the opportunity to be a first-generation college graduate. I am forever iv indebted and humbly appreciative to the late Mr. Howard and Mrs. Nancy Terry for the greatest gift I have ever received. I would also like to thank my husband, Joey Palacios, who has been incredibly supportive and patient during this process. He is the best part of my life. To my mother, I thank her for her loving guidance and support. Finally, to my deceased father, I thank him for instilling values of hard work and opportunity. His legacy lives on with every goal I reach. v TABLE OF CONTENTS Page ACKNOWLEDGEMENTS ............................................................................................... iv LIST OF TABLES ........................................................................................................... viii LIST OF FIGURES ........................................................................................................... ix LIST OF ABBREVIATIONS ..............................................................................................x ABSTRACT ....................................................................................................................... xi CHAPTER I.
