We would like to acknowledge support from the Forest Productivity Cooperative, a graduate assistantship from the Department of Forestry and Environmental Resources at North Carolina State University, and owe thanks to cooperation from ESALQ and IPEF in Piracicaba, Brazil and Antonio Carlos Pedrozo at the Anhembi Research Station. The sampling would not have been possible without the great deal of help from the staff and students in Brazil. We owe thanks to Rafaela Lorenzato Carneiro for her help in the field and organization of many GFMO undergraduates.
