Abstract
The elements of social behavior and social organizations of 4 closely related rodents (Notomys alexis, Pseudomys albocinereus, P. shortridgei and P. desertor) from diverse habitats, and the social organization of 7 other conilurine rodents [Notomys fuscus, N. cervinus, N. mitchelli, Pseudomys australis, P. hermannsburgensis, P. higginsi, Mastacomys fuscus] are described briefly. Most of the data were determined from quantitative observations of animals caged in twos or in larger groups for at least 10 days. Breeding pairs were observed daily throughout pregnancy and parenthood. A dispersed organization and 3 types of communal organization are described, and evolutionary trends in dispersion and territoriality, cohesion, communication and cooperation are discussed.
