山地长耳蝙蝠 Plecotus Macrobullaris 是最近描述的物种，其地理和海拔分布的表征仍在进行中。在不同环境中的捕捞导致了一种有争议的生态认知，大泡虾最初被定义为高山物种，但随后在地中海沿岸和其他低地地区发现。迄今为止，抽样工作并不均衡；这种蝙蝠在西欧的研究比在其分布范围的东部地区的研究更加彻底，在低地的研究比在高地或高山环境的研究更多。为了更深入地了解其分布模式，我们在其 Icnown 范围的几个山区进行了实地调查，使用了一种新颖的雾网技术（本文所述），该技术已被证明对于瞄准和捕获高山环境中低空飞行的开放空间蝙蝠非常有用。我们还从已发表的资源中收集了该物种的所有可用分布数据，并通过联系研究人员，获得了总共 351 个地点的记录（其中 113 个来自其他作者未发表的报告，45 个来自我们自己的实地工作）。我们得出结论，P Macrobullaris 存在于古北界西部主要山脉，从比利牛斯山脉延伸到中东，海拔分布从海平面到 2,800 m。除了专门在山区分布之外，在林线以上捕食的这些蝙蝠数量众多，表明该物种确实是高山物种，表现出与其他仅限于山区且不存在于平地的高度流动脊椎动物相似的模式。然而，由于缺乏对高山栖息地的调查，其明显的海拔分布可能仍然偏向较低地区。
The mountain long-eared bat, Plecotus macrobullaris, is a recently described species, and characterisation of its geographic and elevational distribution is still in progress. Captures in various environments led to a controversial ecological perception, with P macro bullaris initially defined as an alpine species but subsequently found in the Mediterranean seashore and other lowland areas. Sampling efforts hitherto were uneven; this bat has been studied more thoroughly in Western Europe than in the eastern portion of its range, and in lowlands more than highlands or alpine environments. For greater insight into its distribution pattern, we conducted a field survey in several mountain areas of its Icnown range, using a novel mist-netting technique (described herein) that has proven very useful for targeting and capturing low-flying open-space bats in alpine environments. We also gathered all available distribution data on this species from published resources and by contacting researchers, obtaining records at 351 total localities (including 113 from other authors' unpublished reports and 45 from our own fieldwork). We concluded that P macrobullaris is present in the main Western Palearctic mountain ranges, extending from the Pyrenees to the Middle East, and has an elevational distribution from sea level up to 2,800 m. The high number of these bats captured foraging above the timberline, in addition to the exclusively mountainous distribution, indicate that the species is indeed alpine, showing a pattern similar to other highly mobile vertebrates restricted to mountain areas and absent from flatlands. Nevertheless, its apparent elevational distribution may still be biased toward lower areas, due to the scarcity of surveys in high mountain habitats.
