Wall lizards occupied overlapping territories, the size of which seemed to vary directly with the dominance level of the individual. Average territories of both males and females encompassed about 25 square meters. The overlap in territories among males was about 8 percent, and among females, about 18 percent. When both sexes were considered, overlap was 100 percent. This spacing mechanism appeared to be effective in governing the number of resident males but less so in governing number of resident females.
