Effects of habitat fragmentation by artificial structures in Mongolian grasslands on endangered wild ungulates

我们使用卫星跟踪、遥感和地面调查的方法，测试了一条国际铁路和蒙古边境的栖息地碎片化对长距离活动的蒙古原羚和亚洲野驴的影响。结果表明，铁路和边界对野生有蹄类动物的屏障作用，现有和修建铁路和公路的必要性，以及国际合作对保护该地区长距离迁徙的有蹄类动物的重要性。

We tested effects of habitat fragmentation by an international railroad and borders in Mongolia on Mongolian gazelles and Asiatic wild asses that move long-distances, using satellite tracking, remote sensing, and ground survey. Results suggest barrier effects of the railroad and borders on the wild ungulates, necessity of over- and/or under-passes on exist and constructing railroads and road for animals, and importance of international cooperation for conservation of long-distance movement ungulates in this area
