[The spatial relationships and social structure of gerbils in the genus Meriones (Gerbillinae, Rodentia)].
Comparative analysis of spatial relations of 4 gerbil species (M. tamariscinus M. meridianus, M. libycus, M. unguiculatus) shows differences in the system of space use between species and within a species--between individuals of different sex. During reproduction period females are inclined to isolation, small overlap of home ranges and high degree of individualisation. Males occupy large home ranges overlapping with territories of several reproductive females. The territories occupied by the males of midday and tamarisk gerbils do not have clear boundaries and the level of their individualization is quite low. The males of Mongolian gerbil (M. unguiculatus) occupy well defined territories with high level of individualization. Spatial relations of M. libycus males are intermediate. The relationships of the males of three investigated species (M. meridianus, M. libycus, M. tamariscinus) being characterised by the high degree of asymmetry of pair connections, are organised according to the principle of agonistic dominance. Relationships between individuals of different family groups of Mongolian gerbils are based on the locus-dependent dominance, while within one family group-on principle of hierarchical subordination. The meaning of specific peculiarities in use of space and dominance relations are discussed in terms of reproductive strategies.
