The Gobi Jerboa (''Allactaga bullata'') is a species of rodent in the Dipodidae family. It is found in China and Mongolia. Its natural habitats are temperate grassland and temperate desert. The Gobi jerboa (Allactaga bullata) was discovered in 1925 by Glover Morrill Allen. It is found in the Gobi Desert located in northern and northwestern China, as well as in southern Mongolia, and is considered to be the most “desert loving” out of all Gobi rodents (Smith and Xie 2008). Allen first examined an adult male gobi jerboa from Tsagan Nor, Outer Mongolia, which was collected on July 5, 1922 by the Central Asiatic Expeditions and housed at the American Museum of Natural History (Allen 1925). Allen further compared the species Allactaga sibirica annulata and Allactaga sibirica sibirica, to the gobi jerboa because they are all sympatric species. Allen examined forty specimens collected from different regions of Mongolia, and found that while the gobi jerboa was similar in color and appearance to A. sibirica annulata, by exhibiting the same grayer and buffier phases, the gobi jerboa has shorter and broader ears, smaller hind feet, and a much larger globular audital bullae (nearly three times the size), which differentiates it from the A. sibirica annulata. The gobi jerboa was differentiated from A. sibirica sibirica because of its enlarged and globular auditory bullae, and its nearly vertical upper incisors (Allen 1925). Today, there have been 163 recorded occurrences of the gobi jerboa, however there is currently no known data that examines its population status (The Global Biodiversity Information Facility 2013 and Batsaikhan et. al. 2008). ==Range== The gobi jerboa is native to China and Mongolia (Smith and Xie 2008). In China, the gobi jerboa extends east into Xinjiang, west into Nei Mongol, and north into Gansu. In Mongolia, the gobi jerboa can be found in the Great Lakes Depression, Valley of the Lakes, Northern Gobi, Dzungarian, Gobi Desert, Trans Altai Gobi Desert and Alashani Gobi Desert (Sokolov et. al. 1998). Approximately 21% of the gobi jerboa’s range in Mongolia is in protected areas (Clark et al. 2006). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gobi jerboa」の詳細全文を読む スポンサード リンク
