概括
欧洲蝙蝠保护面临着息地丧失带来的挑战. 用半球增强人工休息箱检测能力并没有增加蝙蝠活动;以前与休息室的经验更有影响.
科学领域:
- 生态生态学 生态生态学
- 保护生物学 保护生物学
- 生物声学是一种生物声学.
背景情况:
- 欧洲的息地丧失对蝙蝠产生了负面影响,特别是树木息的物种,原因是树木腔的可用性下降.
- 人工休息箱是一种常见的保护工具,但它们的占用可能很慢,蝙蝠休息室检测机制尚未完全理解.
研究的目的:
- 为了提高人工休息箱的可检测性,用于使用空洞半球的回声定位蝙蝠.
- 为了测试这个假设,修改后的半球箱会吸引更多的蝙蝠,并显示出比标准盒子更高的活动.
主要方法:
- 在德国三个森林地区,部署了30个带有空洞半球的修改后的箱和30个未经修改的箱.
- 使用光束中断传感器监测蝙蝠活动,比较修改和未修改的盒子.
主要成果:
- 与假设相反,蝙蝠活动在带半球的盒子中并没有显著增加.
- 蝙蝠活动受到蝙蝠以前与人工息地的经验的影响更大.
- 光束中断监测在早期发现蝙蝠存在方面比视觉检查更有效.
结论:
- 通过半球来提高宿舍箱的检测能力可能不那么重要,而不是促进蝙蝠熟悉人工宿舍,以有效保护.
- 像光束中断这样的非侵入性监测技术为跟踪蝙蝠在的活动提供了优势.

The human ear cannot distinguish between two sources of sound if they happen to reach within a specific time interval, typically 0.1 seconds apart. More than this, and they are perceived as separate sources.
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...
