对于通过鼻腔发射生物声纳脉冲的回声定位蝙蝠来说，它们的鼻孔被肉质的附属物包围，这些附属物可以阻挡发出的超声波。后叶，作为一个突出的部分，在以前的初步观察中提到，在飞行过程中的一些蝙蝠，但详细的运动模式，从而后叶运动在生物声纳系统中可能的功能作用仍然不清楚。本文对普氏圆叶蝠后叶的运动进行了定量研究。通过同步激光测振仪和声音记录进行了鼻叶运动和超声脉冲发射的时间表征。结果表明，后叶向前倾斜，并在几十毫秒内恢复到原来的位置。鼻叶运动与发射的超声波脉冲在时间上相关。在大部分脉冲持续时间内，后叶表面向前移动。蝙蝠能够打开或关闭运动。从与以前报道的马蹄蝙蝠的鼻叶动态的比较，我们发现类似的比例大小和位移的鼻叶相比，所使用的波长，这意味着类似的行为策略被利用的蝙蝠物种，它可以被应用到不同的组件的信号发射装置。这表明，动态传感原理可能会在生物声纳系统中发挥广泛的作用和研究的时变机制是资本的重要性，以了解回声定位蝙蝠使用的生物声纳传感策略。
For echolocating bats which emit biosonar pulses nasally, their nostrils are surrounded by fleshy appendages that diffract the outgoing ultrasonic waves. The posterior leaf, as a prominent part of the noseleaf, was mentioned in previous preliminary observations to move during flight in some species of bats, yet the detailed motion patterns and thus the possible functional role of the posterior leaf movement in biosonar systems remain unclear. In the current work, the motion of the posterior leaf of living pratt's roundleaf bats has been investigated quantitatively. Temporal characterizations of the noseleaf movement and the ultrasonic pulse emission were performed by virtue of synchronized laser vibrometry and sound recording. The results showed that the posterior leaf tilted forwards and restored to original position within tens of milliseconds. Noseleaf motions were temporally correlated with the emitted ultrasonic pulses. The surfaces of the posterior leaf were moving in the anterior direction in most of the pulse duration. The bats were able to switch the motions on or off. From the comparison with the previously reported noseleaf dynamics in horseshoe bat, we find similar ratio sizes and displacements of the noseleaves compared to the used wavelengths, implying that similar behavioral strategies are utilized by species of bats and it may be applied to different components of the signal emitting apparatus. It suggests that the dynamic sensing principles may widely play a role in the biosonar systems and the investigation on time-variant mechanisms is of capital importance to understand the biosonar sensing strategies used by echolocating bats.
