ACKNOWLEDGMENTS 



I thank Daniel E. Canfield, Jr. for suggesting the concept of this 

 study in constructive criticisms he offered during my master's 

 defense. Dan's challenge provided me with motivation: I chose this 

 topic because I was determined to show him I could resolve the 

 problem. Mark Hoyer and Christine Horsburgh were responsible for 

 collection and management of macrophyte data, and Mark was 

 especially helpful in providing me with this information. The Florida 

 Museum of Natural History provided the vehicles, boats, and 

 equipment for field work. Brian Rood, J. Daniel Bryant and Dennis 

 Crumby assisted in the field. Silvia Ferguson gave much time and 

 hard work in field assistance, and has been a constant source of 

 support throughout this study. 



I am grateful to Claire Schelske, Marty Fleisher, and Arthur 

 Peplow for radionuclide assay of samples used to calculate bulk 

 sediment accumulation rates. I thank Douglas Turley for the time 

 and computer expertise he offered for data management. Paul Zimba 

 gave generous assistance in computer programming during his 

 personal time, making it possible for me to use the CANOCO statistical 

 package. Dana Griffin provided funds for mainframe computing. 

 Martha Love and Sarah E. Whitmore kindly helped with manuscript 

 preparation.
