| 中文摘要: |
| 采用骨髓细胞直接制备染色体的方法,对采自阿拉善黄鼠(Spermophilus alaschanicus Buchner,1888)模式标本产地,内蒙古阿拉善南部典型荒漠区的5号黄鼠(Spermophilus spp.)标本进行染色体研究。结果表明,该种二倍体体细胞的染色体数为2n=38,与达乌尔黄鼠(草原黄鼠)(S.dauricus Brandt,1843)二倍体体细胞的染色体数2n=36,完全不同,且形态特征与达乌尔黄鼠具有明显差异。基于该种的染色体和形态特征以及分布区域,并与国内外相关研究比较的结果,确认该种为阿拉善黄鼠。 |
| 英文摘要: |
| The chromosome karyotype of the Ground Squirrel (Spermophilus spp.) was studied by using bone marrow cell to lining-up chromosome directly.The five samples were collected in the typical desert of southern Alashan,Inner Mongolia.The results showed that the chromosome number of diploid somatic cells was 2n=38,different from that of Daurian Ground Squirrel ( S.dauricus Brandt,1843) whose chromosome number was 2n=36. Chromosome morphological characteristics were also different between the two species.Base on the chromosome number and morphology as well as distribution region,the samples were identified as Alashan Ground Squirrel (S.alaschanicus Buchner,1888). |
