普氏原羚

对普氏原羚的10项血液生理生化指标进行了测定。

Ten physiological and biochemical index in blood were determinated in Procapra przewalskii .

分别以不同浓度的去乙酰化酶抑制剂valproicacid（VPA）对普氏原羚-牛异种重构胚处理不同时间，观察克隆胚胎的发育。

In this study , five experiments were designed to examine the developmental potential of interspecific gazelle-cattle reconstructed embryos . ( 1 ) The gazelle-bovine reconstructed embryos were treated with a deacetylase inhibitor valproic acid ( VPA ) for different time and at different concentrations .

普氏原羚选择芨芨草草原以及其它食物丰富度高、隐蔽条件好和人类干扰少的生境作为采食区；

It preferred to forage in the place with foods of high quantity , of less human disturbance and good cover conditions .

从细胞水平对普氏原羚体细胞培养、生长曲线测定、核型制备与分析、细胞周期、转染条件的优化等方面进行了较为系统的研究。

We did a systematic study of the cells including the cell growth , growth curve , karyotype analysis , cell cycle , and the optimal transfection conditions .

有关普氏原羚的研究发现不仅有助于认识普氏原羚及中国羚羊的系统演化与科学地位，而且为实施对普氏原羚的有效保护提供了科学依据。

These researches not only helped to clarify the phylogeny and taxonomy of the gazelles and antelopes in China but also provided scientific grounds for its protection in China .

由于可食植物丰富的苔草草甸群落、芨芨草群落大部分被围栏圈起，普氏原羚难以进入围栏内取食，主要在可食生物量较低的早熟禾、大籽蒿群落内取食。

Because with more abundant edible plants have mostly been fenced , it is difficult for the gazelles to enter the fences for feeding and they generally feed within with lower edible plants .

影响普氏原羚生境适合度的因素主要为基质类型、坡度、水源远近、植被类型与人类活动。

The key factors influenced the habitat suitability of the Przewakski 's gazelle were identified as the matrix , slope , distance to the water sources , the type of vegetation , and human activities .

考虑人类活动影响时，普氏原羚的适宜和次适宜生境面积分别减少了5.81%和33.09%，而不适宜生境面积增加了38.90%。

In the presence of impacts of human activities , less suitable habitat and suitable habitat decreased by 33.09 % and 5.81 % , respectively , while the area of unsuitable habitat increased by 38.90 % .

评价结果表明，不考虑人类活动影响时普氏原羚的适宜和次适宜生境面积分别为2493.76hm2和18624.06hm2，分别占研究区总面积的8.05%和60.15%；

The result showed that , in the absence of human activities , the area of less suitable and suitable habitats were 2493.76 hm2 and 18 624.06 hm2 , accounting for 8.05 % and 60.15 % of the total area investigated , respectively .
