项目摘要

We succeed to capture Mongolian gazelles (Procapra gutturosa), which is an endangered ungulate, inhabit Mongolian Steppe and migrate long distances seasonally, and to describe their migration routes using satellite-transmitter at the first time. By comparing location data of the Mongolian gazelles with the normalized difference vegetation index (NDVI) acquired by the moderate-resolution imaging spectrometer (MODIS) onboard Terra and Aqua satellite and geographic information data, we suggested a barrier effect of an international in Mongolia railroad on migrations of Mongolian gazelles. We also suggested that the strength of the barrier effect is not the same in both sides of the railroad but stronger in either side. To examine the barrier effect on genetic structure in gazelle populations, samples for genetic analysis were collected and have analyzed.We showed that the shift in NDVI values between summer and winter ranges correspond with seasonal migrations of gazelles, and Mongolian gazelles change their seasonal home ranges year by year, corresponding to interannual variations of spatial distribution pattern of plant productivity and snow cover.It was also suggested that sheep and goats are potential competitors for Mongolian gazelles, by comparing food compositions of feces of sympatric Mongolian gazelles and livestock. The food compositions of Mongolian gazelles were consistent among areas comparing to livestock.Mechanism of winter snow anomaly in Mongolia was analyzed by collecting long-term meteorological data from many meteorological stations. Early warning systems for drought and dzud (cold-season disaster) which course mass mortality of livestock have been constructing by collecting environmental information data such as livestock densities.

我们成功地捕获了蒙古瞪羚（Procapra Gutturosa），这是一种濒临灭绝的不满，居住在蒙古的草原和季节性的长距离迁移，并首次使用卫星变质者来描述其迁移路线。通过将蒙古瞪羚的位置数据与中等分辨率成像光谱仪（MODIS）在船上和Aqua卫星和地理信息数据中获得的归一化差异指数（NDVI）进行比较，我们建议国际铁路在蒙古铁路上具有障碍蒙古瞪羚的迁移。我们还建议，在铁路的两侧，屏障效应的强度都不相同，而在任何一侧都更强。为了检查瞪羚种群中遗传结构的障碍影响，收集了用于遗传分析的样本并进行了分析。我们表明，夏季和冬季范围之间NDVI值的变化与瞪羚的季节性迁移相对应，蒙古瞪羚改变了他们的季节性家居范围逐年，对应于植物生产力和积雪的空间分布模式的年际变化。还建议通过比较同志蒙古瞪羚和牲畜的粪便，是绵羊和山羊是蒙古瞪羚的潜在竞争者。与牲畜相比，蒙古瞪羚的食物组成是一致的。通过从许多气象站收集长期气象数据，分析了蒙古冬季雪异常的机制。干旱和DZUD（冷季灾难）的预警系统通过收集环境信息数据（例如牲畜密度）来构建牲畜的大量死亡率。
