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。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.T...
