A hypervariable simple sequence locus and mitochondrial D-loop sequences were used to analyse genetically a natural population of the larger mouse-eared bat Myotis myotis in southern Bavaria. Tests for population subdivision and direct observations suggest that females return to their natal sites, while males disperse. The males present in female nursery colonies are not related to the females. Paternity assessment for 46 offspring from a particular nursery colony showed that there are no males that monopolize the reproduction, and that the resident males in the colony had only a small mating success. Instead, the results suggest that females actively seek matings outside their colony. Most interestingly, it appears that a group of males about 16 km away from the nursery colony had a relatively high mating success and that this group of males may be related to the females of the nursery colonies. If this finding can be confirmed in a larger study, it may have important consequences for future conservation strategies.
利用一个高变简单序列位点和线粒体D-loop序列对巴伐利亚南部大鼠耳蝠自然种群进行了遗传分析。种群细分测试和直接观察表明，雌性会返回其出生地点，而雄性则会扩散。雌性育幼群体中的雄性与雌性没有亲缘关系。对一个特定育幼群体中46只后代的父系评估表明，没有雄性垄断繁殖，且群体中的常驻雄性交配成功率很低。相反，结果表明雌性会主动在群体外寻求交配。最有趣的是，距离育幼群体约16公里处的一群雄性似乎交配成功率相对较高，且这群雄性可能与育幼群体中的雌性有亲缘关系。如果这一发现能在更大规模的研究中得到证实，可能会对未来的保护策略产生重要影响。
