Acknowledgements

This study would not have been possible without the financial support of the National Science Foundation, which is gratefully acknowledged. I thank Elmer Fink for collecting the vegetation height data. Breeding success data was provided by Charles Facemire. Stephen Bump, Roger Packard, and Charles Facemire helped in setting up grids. Sincere gratitude is expressed to my faculty advisor, Dr. John Zimmerman, and to Dr. Steve Fretwell for their patience and their many helpful suggestions and criticisms which helped to make the summer's work a very rewarding experience.
