【摘要】 对马铁菊头烟、萨氏伏翼与白腹管鼻蝠在飞行状态下的回声定位信号进行了比较研究。结果表明:马铁菊头蝠的回声定位为长恒频一调频声(CF-FM)叫声(叫声持续时间均长于10ms),具有两个谐波;萨氏伏翼与白腹管鼻蝠的回声定位均为宽频调频声(FM)叫声,叫声持续时间分别为3.0±1.3ms和3.6±3.0ms,具有两个或三个谐波。这些回声定位叫声的特性可能与它们所处的生境相适应。

【Abstract】 The echolocation signals of the Rhinolophus ferrumequinum, Pipistrellus savvi and Murina leucogaster were compared when the bats were flying in the laboratory. The results revealed that the echolocation call of R. fermmequinum was a long CF-FM signal with two harmonics, the duration of which was more than 10 ms. The echolocation calls of both P. savvi and M. leucogaster were short, broadband frequency-modulated (FM)signals with two or three harmonics, the duration of which were 3.0±1. 3ms and 3. 6±3. 0ms, respectively. The characteristics of the echolocation calls of bats perhaps made them adapt to their foraging habits and surroundings.
