摘      要：Color variation among populations is thought to be either due to genetic variation or phenotype *** this study,we found that an agamid lizard,Phrynocephalus theobaldi,inhabiting elevations greater than any other reptile,displayed a significantly darker spotted marking on the central ventral abdomen in higher populations than in lower *** grey spotted area only occurred in elevations4200 m,and also increased with increased *** ratio of the size of the dark colored area to the degree of skin luminance/reflectance was used to test whether the lizard has a larger and darker spotted area at higher *** ratio was significantly positively associated with elevation rather than substrate *** lizard did not display sexual difference in this *** had a significant influence on the brightness of central abdomen,but temperature-related plasticity of this trait was much smaller than the magnitude of the difference between higher(4200 m)and lower populations(4200 m).Common garden experiments showed that genetic inheritance,rather than phenotype plasticity,played a dominant role in this *** research addressed the darkness of a body region that is rarely analyzed because it is shielded from direct *** idea that ventral color could be related to thermoregulation is shown to be worthy of further research.
