Sceloporus jarrovi exhibits intraspecific differences in temporal and microhabitat resource usage. During the summer months of 1974 and 1975, most adult activity occurred in the early morning while most juvenile activity occurred near noon. Lizards were active an average of only 2.5 days/wk. Because the animals were active on different days and at various times of the day, defended territories sometimes overlapped spatially. Territoriality of S. jarrovi is closely tied to the maintenance of an adequate food supply a temporal distribution of territories may increase feeding efficiency. Perch site differences were also noted.
