Movement behavior and habitat use of the long-eared bat species and were studied in the Havelland region in Brandenburg (Germany). Data collection included mist-netting, radiotelemetry, reconstruction of prey items, and monitoring of roosting sites. Body measurements confirm a high degree of phenotypic similarity between the two species. Total activity areas (100% Minimum Convex Polygons, MCPS) of (2828.3 ± 1269.43 ha) were up to five-fold larger compared to (544.54 ± 295.89 ha). The activity areas of contained up to 11 distinct core areas, and their mean total size (149.7 ± 0.07 ha) was approximately three-fold larger compared to core areas of (49.2 ± 25.6 ha). The mean distance between consecutive fixes per night was 12.72 ± 3.7 km for and 4.23 ± 2.8 km for While was located most frequently over pastures (>40%) and meadows (>20%), was located mostly within deciduous (>50%) and mixed forests (>30%) in close vicinity to its roosts. Roost site monitoring indicates that the activity of is delayed relative to in spring and declined earlier in autumn. These phenological differences are probably related to the species' respective diets. Levins' measure of trophic niche breadth suggests that the prey spectrum for is more diverse during spring (B = 2.86) and autumn (B = 2.82) compared to (spring: B = 1.7; autumn: B = 2.1). Our results give reason to consider these interspecific ecological variations and species-specific requirements of and to develop adapted and improved conservation measures.
在德国勃兰登堡州的哈弗兰地区，对长耳蝠物种的运动行为和栖息地利用情况进行了研究。数据收集包括雾网捕捕、无线电遥测、猎物项目重建以及栖息地监测。身体测量结果证实这两个物种之间存在高度的表型相似性。[物种名称1]的总活动面积（100%最小凸多边形，MCPs）为（2828.3±1269.43公顷），相比[物种名称2]（544.54±295.89公顷）大了五倍之多。[物种名称1]的活动区域包含多达11个不同的核心区域，其平均总面积（149.7±0.07公顷）相比[物种名称2]的核心区域（49.2±25.6公顷）大约大三倍。[物种名称1]每晚连续定位点之间的平均距离为12.72±3.7千米，[物种名称2]为4.23±2.8千米。[物种名称1]最常出现在牧场（>40%）和草地（>20%）上空，而[物种名称2]大多位于落叶林（>50%）和混交林（>30%）中，且靠近其栖息地。栖息地监测表明，[物种名称1]在春季的活动相对于[物种名称2]有所延迟，在秋季则更早下降。这些物候差异可能与物种各自的饮食有关。莱文斯的营养生态位宽度测量表明，与[物种名称2]相比，[物种名称1]在春季（B = 2.86）和秋季（B = 2.82）的猎物谱更为多样（[物种名称2]：春季：B = 1.7；秋季：B = 2.1）。我们的研究结果促使人们考虑这些种间生态差异以及[物种名称1]和[物种名称2]的物种特定需求，以制定适应性更强、更完善的保护措施。
