STUDY ON THE DISTRIBUTION AND HABITAT CHARACTERISTICS OF BRANDT’S VOLE

Abstract

Many species have suffered changed habitable area due to recent climate change or/and human activities. Brandt’s vole (Lasiopodomys brandtii) is same as it.The species is undergoing a continuous habitat change as a consequence of the human’s production, climate change and retrogressive succession of grassland ecosystems. The distribution of the Brandt’s vole was update in China and Mongolia. Based on the historical distribution map, which was made by overlaying the historical data with vegetation type’s map of the grassland resources in China and Mongolia. And the distribution map was modified according to the on-site investigate data in recent years. The current species’ distribution was range Hulunbei’er, northern Xilinguole, which comprise a landscape through the east of Dornod Aimag, Mongolia, and southern Hunshandake Sandy Land in China which just includes the areas around the Zhengxiangbai Qi. There were no the species in the east of Daxinganling Mountains, Liaoning, Shanxi province and Xinjiang Uyghur Autonomous Region of China. The species’ distribution is discontinuous in Mongolia, including western, middle and eastern Mongolia. The western distribution along Hangay Mountains and extends for the west, the northern boundary extended to between Ider river and Chulouk river. Southward reaches of the Malhin along the plain between Hangay Mountain and Altay Mountain. The middle and east of the species’ range lie in the part areas of Tov, Hentiy, Dundgovi, Dornogovi. extends to Hulunbei’er and northern Xilinguole eastwardly and southwardly respectively, northward reaches of the Trans-Baikalia, Russia.
