INTRASPECIFIC VARIATION IN THE SPATIAL AND SOCIAL ORGANIZATION OF THE AFRICAN STRIPED MOUSE
It is suggested that group living in the succulent karoo is in response to habitat saturation and the benefits of philopatry, whereas living alone in the grasslands may be a response to limiting resources, such as food.
The striped mouse (Rhabdomys pumilio) from the succulent karoo, South Africa: a territorial group-living solitary forager with communal breeding and helpers at the nest.
Group living in the semiarid succulent karoo of South Africa is possibly due to ecological constraints imposed by habitat saturation because of a year-round stable food supply as well as associated benefits of philopatry.
Demography of the striped mouse (Rhabdomys pumilio) in the succulent karoo
Reproductive competition favours solitary living while ecological constraints impose group-living in African striped mice.
It is concluded that group-living is favoured by constraints imposed through habitat saturation and by its benefits (improved thermoregulation by huddling, group-territoriality and predator avoidance), and that reproductive competition is a major force favouring solitary living in striped mice.

Female striped mice (Rhabdomys pumilio) change their home ranges in response to seasonal variation in food availability
It is suggested that female striped mice shift their home ranges seasonally to gain access to protein-rich young plant material, which is important for breeding, and home ranges during the breeding season in spring had a higher percentage of annuals than dry season home ranges measured in spring.
FEMALE MATE PREFERENCE AND REPRODUCTIVE ISOLATION IN POPULATIONS OF THE STRIPED MOUSE RHABDOMYS PUMILIO
- N. Pillay
Diversity has occurred in allopatry of the striped mouse Rhabdomys pumilio, resulting in populationspecific communication signals and in particular olfactory cues, assortative mate choice, and pre-mating reproductive isolation.
Social flexibility and social evolution in mammals: a case study of the African striped mouse (Rhabdomys pumilio)
The striped mouse Rhabdomys pumilio provides a unique opportunity to study both the ultimate and proximate causes of sociality by comparing between solitary and group‐living individuals of the same population, and reveals that relative fitness of alternative reproductive tactics depends on the prevailing environment.

Reproduction and postnatal development in the bush Karoo rat Otomys unisulcatus (Muridae, Otomyinae)

The reproductive biology and postnatal development of the bush Karoo appears to reflect a compromise between exploiting sporadically abundant resources and the occupation of stick lodges, which may provide a favourable microclimate to buffer the harsh external climate.
