白腹管鼻蝠华北与东北冬眠群内RAPD分析和亲缘关系的比较研究

用随机扩增ＤＮＡ多态（ＲＡＰＤ）方法分析白腹管鼻蝠在华北和东北两地冬眠群群内与群间个体之间的亲缘关系，探讨冬眠群的结构组成及其相互关系。结果显示：华北两个白腹管鼻蝠冬眠群内个体间遗传相似性平均分别为０８５８和０９３３，两群之间的遗传相似性平均为０８４２，群内与群间个体之间在遗传相似性方面没有明显差别；东北冬眠群内的遗传相似性平均为０６０４；华北和东北两地冬眠群间的相似性只有０５１３和０５２１。据此可认为，在同一及邻近洞中形成的白腹管鼻蝠冬眠群的组成可能是选择来自同一种群中亲缘关系较近的个体，在华北冬眠的种群和在居留地东北冬眠的种群之间的亲缘关系较远。

COMPARATIVE STUDY OF KINSHIP AMONG HIBERNATION GROUPS OF GREATER TUBE-NOSED BATS(MURINA LEUCOGASTER) IN NORTH AND NORTHEAST OF CHINA

The kinship and construction were analyzed among intra groups and inter groups in hibernation groups of greater tube nosed bats (Murina leucogaster) in northern and northeast of China with RAPD method. The results were as fellows: the mean genetic similarity in two groups of north of China was 0 858 and 0 933 respectively; the mean genetic similarity between two groups of north of China was 0 842; there was no significant genetic difference among intra groups and inter groups of north of China. The mean genetic similarity of group in northeast was 0 604; The mean similarities were only 0 513 and 0 521 between north and northeast. According to these results, individuals of hibernation group in same and adjacent caves maybe come from close kinship population of greater tube nosed bats, and there is distant relationship between north and northeast.
