摘要/Abstract

摘要： 在自建网室（9 m×4 m×4 m）内驯养马铁菊头蝠（Rhinolophus ferrumequinum），利用超声波探测仪录制蝙蝠不同状态下回声定位声波，声波录制与红外摄像保持同步。结果表明，马铁菊头蝠回声定位声波为调频(FM)/恒频(CF)/调频(FM)型；在蝙蝠接近猎物过程中，声脉冲持续时间和间隔时间显著变短，下调FM（即tFM）组分变得愈为显著，捕捉猎物瞬间，产生捕食蜂鸣；飞行与悬挂状态相比，声脉冲重复率、主频率、声脉冲时间、声脉冲间隔和能率环的差异均达到显著水平。

Abstract: In this study, Rhinolophus ferrumequinum was trained in a 9 m × 4 m × 4 m net room, an Ultrasound Detector Advice was used to record its echolocation calls, and the video-recordings were synchronized with acoustic recordings. The results showed that the echolocation calls of R. ferrumequinum were of (FM/) CF/FM type. The pulse duration and interpulse interval decreased abruptly when the bat approached prey items, and the terminal FM component became more dominant. Foraging buzz was emitted at the moment of capture. There were significant differences in pulse repetition rate, dominant frequency, pulse duration, interpulse interval, and duty cycle during the bat was at flying and hanging.
