Geographic
Differences of Growth Rate of Sceloporus Lizards (Sauria:
Iguanidae)

Abstract
Laboratory produced hatchlings of Sceloporus gracious
graciosus, S. undulatus consobrinus, S. u.
garmoni and S. u. undulatus that were raised under
identical social, thermal-gradient and feeding environments grew at
significantly distinct, population-specific rates.
Growth rates expressed in the laboratory closely approximated those
measured in the field for some populations, but were higher in the laboratory
for others. Juvenile growth rate
differences measured in the field seem due in part to genetic differences and in
part to differences in the quality of the natural growing environment.
