The territorial structure of population of midday gerbil (Meriones meridianus) in Zaunguzkie Karakuma is subjected by considerable changes. It depends from conditions of living and generative conditions of individuals. If density of population is less than 15-20 of individuals on 1 hectare, midday gerbils spend single way of life independently from participate in breeding. If density is more than 15 individuals on 1 hectare (among non-breeding individuals) it is possible that. one hole will be use by several groups. The territorial structure of population midday gerbils is more stable in the period of breeding. The: females use home range with size about 1000-2500 m2, defending the border from others adult females. The mails attend the territory of 2-7 females, avoiding contacts with each other. The mails don't defend there home range. During the most severe individualization of territory social relations of midday gerbils direct not only on dispersal among territory but also on consideration in inside population groups. Conservatism is peculiar to adult gerbils, they use the same home range during whole life. The most mobility is character to young individuals in the period of their settle and adult mails during the period of breeding. The range of changes territory organization and structure population of midday gerbils recover variety spatial organization representatives of genus of Meriones.
