VITA...........................................................................................................................................158 ACKNOWLEDGMENTS There are so many people to thank for all of their support, guidance, and friendship during my time here at VIMS. First and foremost, I thank my family for all of their support, patience, and love. My family dealt with me during the good times and the bad times but their confidence in my ability to complete this degree motivated me, even when I could not muster the strength to motivate myself. I also want to thank my two beautiful nieces for reminding me with their enthusiasm and sense of wonder why 1 first became interested in Marine Science. I also thank the members of my lab for being amazing friends and colleagues; 1 have learned so much from working with all of you. Regardless of the weather conditions, you made early morning and late night sampling trips out to the public pier fun! In addition, our mid-day coffee runs were invaluable for my sanity and my development as a scientist. I would also like to thank all of my friends at VIMS for reminding me that it is okay to turn off the computer and set aside work for a bit. You all have made this journey to the dissertation fun and far less lonely. I also want to acknowledge so many people at VIMS for taking time out of their day and sharing their expertise with me. I want to thank D. Sennett for passing on his aquarium and animal husbandry skills and M. Stratton, K. Omori, and A. Buchheister for their help with R. I also want to thank my undergraduate mentor, G. Sancho for all of his guidance and insights. He has been a constant motivator and has provided so much positive reinforcement at the moments I needed it the most. I have had the opportunity to take advantage of many international research experiences and I would like to thank all of the people that made these trips possible, specifically N. Strydom and P. Pattrick. Finally, I want to thank Eric Hilton, my advisor, for taking me on as a student and believing that I could complete dissertation level research. Thanks to his comments, my ability to write and communicate my science has improved drastically since my arrival here at VIMS. He was also supported of my scientific wanderlust and allowed me to take advantage of research opportunities around the globe.

Mean feeding apparatus length (mm) or area (mm2) for Cynoscion nebulosus, C. regalis, Micropogonias undulatus and Leiostomus xanthurus once differences in the jaw elements were observed. Average measurements were calculated between the first and second split (8.4-14.1 mm HL) and the second and third split (14.1- 19.8 mm HL) observed in the regression tree. Sample sizes for each split are
