ACKNOWLEDGMENTS
My thanks go to Tom Patch whose enthusiasm about and introduction to the life
sciences got me started. I am especially grateful to Dr. Martin Trinkle who introduced
me to the exciting field of evolutionary biology and whose endless ideas and
encouragement led to this and most other studies un which I have been involved. I would
like to thank Laurie Mason for hours of discussion about reptilian biology and my
introduction to field biology in Kansas.
My field research in the Chiracahua Mountains would have lacked some of its joy
without the presence and assistance of Sandy and Michael Malcom. Dr. Ray Callinger
allowed me access to unpublished data, his study areas, and to his cabin at the Cave
Creek Motel. The many evenings discussing biology and the happy days in the field will
long be remembered.
Special thanks go to my parents, brothers, and sister who helped me along the
way. I am sure they suspected it was endless. Also, special thanks to the Alexander Box
family for their assistance and friendship.
The Department of Zoology, the Graduate School and the National Science
Foundation provided financial support for my research and studies.
Finally, I would like to thank my committee for their guidance, equipment,
financial support, and assistance throughout my studies.
