may be an artifact of long-term hand recapture techniques. Kiester et al. 
(1982) considered radiotelemetry to be a basic prerequisite for determining 
transient behavior in turtle populations. 
The possible importance of transient males in maintaining gene 
flow between adjacent turtle populations was suggested by Kiester et al. 
(1982). In fact, genetic exchange among populations of freshwater 
turtles in adjacent aquatic habitats has been demonstrated electrophoretically 
(Scribner et al. 1984). The phenotypic homogeneity exhibited by the 
widely distributed spotted turtle (Ernst and Barbour 1972) may be a 
result of this behavior. 
ACKNOWLEDGEMENTS.— I thank Jim Knight, Marie Fulmer, 
Aileen Adriano, Steve Gotte, and Tony Mills for field assistance. Jim 
Knight, Whit Gibbons, Mara McDonald, and two anonymous reviewers 
provided useful criticisms of an earlier version of the manuscript. 
Special thanks are extended to Justin Congdon and Robert Fischer for 
showing me how to use radiotelemetry effectively. This research was 
supported by Contract DE-AC09-76SROO819 between the U.S. Department 
of Energy and the University of Georgia.
