Following a dramatic decline last century, the British population of the endangered greater horseshoe bat Rhinolophus ferrumequinum is highly fragmented. To examine the consequences of fragmentation and limited dispersal on patterns of genetic structure and variation, we used microsatellite markers to screen bats from around 50% of the known maternity colonies in Britain, and two areas from continental Europe. Analyses revealed that Welsh and English colonies were genetically isolated. This, and lower variability in Britain than north France, may result from either genetic drift, or the species' colonization history. Gene flow among most neighbouring colonies was not generally restricted, with one exception. These findings have important implications for the ongoing conservation management of this species.
在上个世纪经历了急剧下降之后，英国濒危的大马蹄蝠（Rhinolophus ferrumequinum）种群高度分散。为了研究种群分散和有限扩散对遗传结构和变异模式的影响，我们使用微卫星标记对来自英国约50%已知育幼群落以及欧洲大陆两个地区的蝙蝠进行了筛选。分析表明，威尔士和英格兰的群落存在基因隔离。这以及英国比法国北部较低的变异性，可能是由遗传漂变或该物种的殖民历史导致的。除了一个例外，大多数相邻群落之间的基因流动通常不受限制。这些发现对该物种当前的保护管理具有重要意义。
