![]() Dominant herbaceous or gramineous plants species are caragana ( Caragana tibetica), fabales ( Ammopiptanthus mongolicus), Cynanchum ( Cynanchum komarovii), and Zygophyllum pterocarpum. In Mongolia, vegetation surrounding hamster burrows typically extends to a height of 75cm. ![]() Sparse, shrubby vegetation in these habitats also aids in burrow construction. The sandy soils of semi-deserts, steppes and grasslands offer the preferred terrestrial substrate over clay soils. To allow for proper construction, the sand horizon of the soil must be more than one meter in depth. Roborovski's desert hamsters are found in habitats with loose soil that facilitates their habit of digging burrows into the sides of sand dunes. ( Chi and Wang, 2011 Feoktistova and Meshchersky, 2005 Meschersky and Feoktistova, 1999 Meshchersky and Feoktistova, 2011 Nowak, 1999 Ross, 1994 Shar and Lkhagvasuren, 2008 Sokolov and Orlov, 1980) Other than transport through the pet trade, Roborovski's desert hamsters are not known as established introduced species elsewhere. They are less numerous in the Ordos desert of China, south of the Zaisanskaya Depression in east Kazakhstan and in the southern portions of the Tuva Republic (Russia). Their northern range extends from the Hunshandake sandy land and the Mongolian Gobi deserts (Gobi Altai Mountain Range, Great Lakes Depression, Valley of the Lakes, Northern Gobi, Eastern Gobi, Djungarian Gobi Desert, Trans Altai Gobi Desert and Alashani Gobi Desert) to adjacent territories of northern China. ![]() They are most numerous in south, central and northwestern Mongolia. ![]() Roborovski's desert hamsters ( Phodopus roborovskii) are endemic to the southern Palearctic biogeographic region. ![]()
