Value of species
According to different views includes from three to six subspecies (Shenbrot 1991).
Distributed from forest-steppes to northern parts of deserts from W Ukraine and European Russia (S) through Kazakhstan and N Uzbekistan to W Siberia and W Xinjiang, China (Shenbrot et al. 1995, Wilson and Reeder 2005).
Widespread across most of its range, but distributed irregularily because of fragmentation of suitable habitats and human-caused landscape change. In Ukraine west of the Dnepr the species was common until the mid 1920s (Bilsky 1929), but there are no recent records of the species there (Shenbrot et al. 1995).
One of the most ecologically plastic jerboa species. Inhabits various habitats; in the northern part of the range the main limiting factor is grass density, and the species is restricted to areas with sparse vegetation. In steppe zone often inhabits roadsides, field edges, pastures and flat slopes of ravines. In deserts and semideserts occurs in all habitats except moving sands. Prefers areas with loamy soils, with absinth and succulent vegetation. Feeds on underground and green parts of plants, also on seeds and occasionally on insect and molluscs. Has three types of burrows: permanent summer and winter, and temporary. Enters hibernation in autumn with the first frost. Exits hibernation in March-April. Reproductive period is prolonged. Pregnant females may be found from March to July. During the reproductive period females may have two litters. Litter size ranges from 1 to 8 young, usually 3-6.
