Most social interactions among lizards are between breeding individuals.<ref name="Pianka-Vitt86">Pianka and Vitt, pp. 86.</ref> [[Territory (animal)|Territoriality]] is common and is correlated with species that use sit-and-wait hunting strategies. Males establish and maintain territories that contain resources that attract females and which they defend from other males. Important resources include basking, feeding, and nesting sites as well as refuges from predators. The habitat of a species affects the structure of territories, for example, rock lizards have territories atop rocky outcrops.<ref name="Pianka-Vitt94">Pianka and Vitt, pp. 94–106.</ref> Some species may aggregate in groups, enhancing vigilance and lessening the risk of predation for individuals, particularly for juveniles.<ref>{{cite journal |author1=Lanham, E.
