9 Lee C. Drickamer: I thank the many undergraduates,
particularly at Williams College, graduate students and
undergraduates at Southern Illinois University, and fac-
ulty colleagues at those two schools and at Northern
Arizona University for their invaluable assistance, dis-
cussions, and enthusiasm. Portions of the work in my
laboratory and in field settings were supported by grants
from the National Institutes of Health and National Sci-
ence Foundation. I thank the editors for their foresight
in organizing this volume and for their diligence in put-
ting it all together.
10 Albrecht I. Schulte-Hostedde: I thank the editors for the

constructive, incisive, and helpful comments on earlier
versions of this chapter.
14 F. Stephen Dobson: I owe special thanks to the editors
for suggesting that I review the genetic properties of so-
cial breeding groups. Ron Chesser provided patient in-
struction on the gene dynamics of social breeding groups
during the summers of 1993 –1996, and the Savannah
River Ecology Laboratory provided support via Visiting
Faculty Fellowships in 1993, 1994, and 1996. In 1995,
I was an Oak Ridge Institute for Science and Education
Research Fellow at SREL. I especially appreciate the
support of the director of SREL, M. H. Smith, during
these 4 years. R. K. Chesser, N. Perrin, and M. F. Win-
terrowd provided excellent comments and suggestions

thanks to John Hoogland, who generously made his in-
credible field data so freely available, and to Dave Foltz,
for encouraging analyses on his and John’s allozyme
data. Preparation of the current manuscript was com-
pleted while I was supported by a National Science
Foundation grant for research (DEB-0089473).
