施氏长翼蝠（Miniopterus schreibersii）是一种穴居蝙蝠，广泛分布于古北界西部，横跨南欧和中欧、北非、安纳托利亚、中东和高加索。我们调查了社会结构及其对该物种的遗传组成的影响，使用10个核微卫星标记和线粒体细胞色素B基因的部分片段。从该物种的整个环地中海范围的样本进行了检查。本地结构，以前检测到的人群中的M。使用线粒体标记的schreibersii在微卫星标记中没有观察到，表明该物种的扩散偏向雄性。一些证据支持冰后期欧洲的扩张，安纳托利亚可能是末次盛冰期（LGM）的主要避难所。然而，对这一假设的支持并不像以前使用线粒体DNA标记检测到的那样强。这可能是由于男性介导的扩散的影响逐渐减弱，在距离冰川避难所相对较远的地区，细胞核多样性的补充速度比线粒体多样性快。
Miniopterus schreibersii is a cave-dwelling bat species with a wide distribution in the western Palearctic spanning southern and central Europe, North Africa, Anatolia, the Middle East, and the Caucasus. We investigated the social structure and its effects on the genetic makeup of this species, using 10 nuclear microsatellite markers and a partial fragment of the mitochondrial cytochrome b gene. Samples were examined from the species' entire circum-Mediterranean range. Local structuring that was previously detected among populations of M. schreibersii using mitochondrial markers was not observed for microsatellite markers, indicating male-biased dispersal for the species. Some support was found for postglacial expansions in Europe, with Anatolia potentially acting as the primary refugium during the Last Glacial Maximum (LGM). However, support for this hypothesis is not as strong as that previously detected using mitochondrial DNA markers. This is likely due to the diminishing effect of male-mediated dispersal, replenishing the nuclear diversity faster than the mitochondrial diversity in regions that are relatively far from the glacial refugia.
