were conspecific, and they recognized this taxon only at subspecific level, not as a separate valid species as was originally described by Ognev in 1935. Kovalskaya and colleagues and Cserkész and colleagues hypothesized that the large amount of chromosomal variation present within subspecies severtzovi may have resulted from multiple isolation-reticulation events triggered by continual changes in courses of large rivers (e.g. Volga and Don) in the southern Russian plain, Pleistocene glaciation events, or ancient hybridization events. Nevertheless, such rapid chromosomal evolution and large amount ofvariation are unusual within a single mammalian species. According to the biogeographical hypothesis of Kovalskaya and colleagues, together with transgressions by the Caspian Sea, climatic influences favored shift of the ancestral population of S.

Head—body 60-5-72 mm, tail 745-82 mm, ear 9-5-13-3 mm, hindfoot 14-5-16-5 mm; weight 6-2—12 g. Pelage colors of Southern Birch Mice vary according to age and location. Mid-dorsalstripe bordered by two narrow bright beige stripes on both sides is noticeable and characteristic; brighter stripes are often bordered by darker lines resulting in one distinct stripe and two lateral diffused dark stripes on either side. There are three main pelage variations that historically have been identified as distinct subspecies, but this conception is outdated. Nominate

has the basic form, with grayish brown to yellowish dorsum and grayish white venter; three dark medial stripes are typical but are not always present. Ognev in 1935 noted that dorsum of paler variation, sometimes called the “Pale Birch Mouse” (S. s. vaga), is rather grayish with pale yellow tinge and without diffused lateral dark stripes. Cserkész and colleagues in 2016 captured vaga in the Emba Valley, Kazakhstan, with “typical

color” (visible beige stripes alongside black dorsal stripe and diffused lateral dark stripes). The third variation, the “Siberian Birch Mouse” (S. s. sibirica), has broader mid-dorsal stripe and distinct dark lateral stripes; dorsum is dark gray, with yellow-rusty overtone, resembling that of “Severtzov’s Birch Mice” (S. s. severtzovi). Hindfoot is long, c.23% of head-body length. Tail is ¢.100 —135% of head-body length. Condylobasal lengths are 17-3-18-5 mm, zygomatic breadths are 8:4-9-8 mm, interorbital breadths are 3-8-3-9 mm, and lengths of upper tooth rows are 2:8-3-2 mm. Glans penisis cylindrical and covered with small spines and is characterized by single penile spike (1-2 mm). Diploid numbers are 2n = 18-24, with several distinctive karyotypic forms. External and cranial measurements were taken from specimens captured in the Orenburg region, Russia, published by G. I. Shenbrot and colleagues in 1995 and 2008.

Undisturbed, or relatively undisturbed, open habitats such as forest steppe, moist mesophilous grasslands, dry sandy steppe, and semi-desert at elevations up to c.1000 m. The Southern Birch Mouse is eurytopic but with a particular affinity for habitats with tall cover and well-developed herbaceous vegetation; however, it is also found in semi-deserts, primarily in sandy steppes with meadowsweet (

) shrubs. Until the 1960s, Southern Birch Mice might have inhabited agricultural fields but now possibly avoid areas of intense agricultural activity. A. A. Tsvetkova and colleagues in 2008 and Tsvetkova and M. L. Oparin in 2016 reported that birch mice occupy fallow fields and margins of active fields but densities in undisturbed steppes were much greater. In 2016, Cserkész and colleagues captured individuals in somewhat disturbed habitats in Russia that showed evidence of light to moderate grazing by livestock but had vegetation cover of more than 60%. They also captured subspecies severtzovi in Ukraine and Russia in typical sand dune steppes with 40-70% cover, dominated by

Reproduction of the Southern Birch Mouse begins shortly after emerging from hibernation, usually toward the end of May and beginning ofJune, depending on environmental factors, sex, and age of individuals. One litter is produced per year, with 2-8 young. Gestation lasts 25-30 days.

Southern Birch Mice are nocturnal and crepuscular and sometimes active during the day based on many daytime observations. In captivity, Voronov noted two active periods: main one beginning at dusk and the other before dawn. They were more active during the day if inadequate food was provided; under such conditions in the wild, Southern Birch Mice are likely more easily captured. This higher prey potential is suggested by high numbers of Southern Birch Mice in owl pellets and stomach contents of birds of prey (harriers and kestrels) compared with those of other nocturnal rodents. While sleeping, the Southern Birch Mouse lies on its side or sits on its hindfeet, with its tail wrapped around its body. Body temperature is reduced, and in some cases, torpid individuals are unresponsive. This sleeping pose and ability to enter daily torpor are also typical for other species of

. Voronov noted that captive individuals were less active by the end of September, and in October-November, they slept almost the entire day and only occasionally left the nest to obtain food. In the wild, Southern Birch Mice hibernate c¢.6-7 months of the year, usually from late September until the beginning of April in southern Ural and in October-May in the steppe region of Kazakhstan, according to V. E. Flint in 1960.

Southern Birch Mice are agile and scamper about by moving with small jumps. They easily climb vertical stalks and use their tails to help balance. They use burrows of other rodents and other shelters such as holes among stones and tree roots. Captive Southern Birch Mice have been observed living in family groups rather peacefully, sleeping in the same nest together even though individuals differed in temperament. Social relationships might exist in wild populations of Southern Birch Mice as was presumed for the Tian Shan Birch Mouse (S.

|

Classified as Least Concern on The IUCN Red List. Severtzov’s Birch Mouse was treated as a full species and classified as Least Concern on The IUCN Red List. Under optimal conditions and habitats, Southern Birch Mice can reach high densities and be the dominant member of small mammal communities. Distribution covers an expansive area containing unused or modestly used pastures or cultivated lands and unproductive regions such as sand and shrub steppes of Russia and Kazakhstan where only local factors such as small-scale development, utilization, and fires threaten populations. Intensive agricultural practices such as overgrazing, mechanical mowing, and cutting or plowing of grasslands can render favorable habitats such as meadows, grasslands, and fallow fields inhospitable.
