为了解蝙蝠科种间亲缘关系,采用随机引物对河南省蝙蝠科7种蝙蝠进行DNA多态性研究,从20个随机引物中优化出12个引物对基因组DNA进行扩增,共扩增出223条DNA谱带,平均每个引物扩增出18.6条谱带。RAPD聚类结果表明,种间亲缘关系较远,种内亲缘关系较近。对同种蝙蝠而言,同一地理区域的蝙蝠个体之间分化较小,不同地理区域的蝙蝠个体之间分化较大。同时对鼠耳蝠属和长翼蝠亚科的分类地位也进行了讨论。  相似文献   

Amniogenesis in the African yellow bat,Scotophilus dinganii     

《African Zoology》2013,48(2):234-239

The African yellow house bat, Scotophilus dinganii, was found to be seasonally monestrus, carrying a single foetus in each of the two uterine horns of the bicornuate uterus. Implantation was superficial, with amniogenesis initiated early during embryogenesis. The amnion in S. dinganii was a schizamnion, and it is deduced that its formation was preceded by cavitation of the inner cell mass, with formation of the definitive amniotic cavity, where the floor of the cavity eventually formed the embryonic disc and its roof the ectodermal part of the true or definitive amnion.  相似文献
