草原兔尾鼠 meaning in English
lagurus lagurus
steppe lemming
Examples
- Extensive mitochondrial dna polymorphisms were found among lagurus lagurus , mus musculu ， rattus norvegicus and mice . the findings will help us to understand the dispersion and evolution of these animals
通过琼脂糖凝胶电泳对这些片段进行测定，同时估算出草原兔尾鼠线粒体dna的长度约为16 . 6kb 。 - With a pair of degenerate primers designed according to the conserved region among the known cdna sequences of five rodents , a cdna fragment was generated by rt - pcr from total rna isolated from ovaries of lagurus lagurus
首先根据已发表的五种啮齿目动物zp3cdna序列同源性分析结果设计特异性引物， rt - pcr扩增草原兔尾鼠zp3 （ lzp3 ） cdna保守序列。 - In this study , by combining rt - pcr and race , a full - length cdna encoding the lagurus lagurus zp3 ( lzp3 ) was isolated from the lagurus ' s ovary and cloned into a prokaryotic expression vector and a eukaryotic expression vector for further immunocontraceptive investigations
本论文研究工作采用rt - pcr与race相结合的方法，首次克隆了草原兔尾鼠zp3全长cdna并进行了序列分析，构建了真核表达质粒，为草原兔尾鼠免疫不育的研究奠定了基础。 - According to measured data , testis sizes from animals captured in september 2000 were different remarkably from that in april and july 2001 , and not differences among their age groups , which was indicated that l . lagurus in september 2000 did not have reproductive abilities . by use the same method , we have observed that l . lagurus in april 2001 and groups from - age and - age ( old ) in july 2001 have reproductive abilities . in addition , the reproductive ability from the - age group in july 2001 was intermediated between the groups in september 2000 , - age group in april and - age group in july 2001
我们对不同时间参与繁殖的雄鼠睾丸大小的测定结果表明， 2000年9月雄鼠睾丸大小与2001年4月和7月的有显著性差异，表明2000年9月草原兔尾鼠雄鼠进入繁殖休止期； 2001年4月种群中龄和龄雄鼠睾丸大小无显著性差异，与2001年7月的相比有显著性差异，但与2001年7月种群的龄鼠和龄鼠的相比无显著性差异，表明2001年4月和2001年7月种群的龄和龄草原兔尾鼠雄鼠具繁殖能力； 2001年7月的龄雄鼠睾丸大小与2000年9月的有显著性差异，表明该时期龄雄鼠的繁殖力介于2000年9月种群和2001年4月和7月种群的龄鼠和龄鼠之间。 - According to the live coefficient c , we modified the predictions for this age group and come to a conclusion that is corresponding to actual field data . in other words , the numbers of - age and - age were nearly zero with their densities below 4 / hm2 . these results suggest that l . lagurus population began to decline
运用校正后的存活系数继续预测，其结果与2001年9月的野外调查结果基本一致，证实当年草原兔尾鼠的数量非常少，低于4 . 0只/公顷，且龄鼠和龄鼠几乎为零。
