生物震颤是由生物体产生的振动，通常是沿介质边界的表面波。虽然不同的爬行动物物种利用基质传播的振动，但通过生物振动进行的真正的同体交流尚未在蜥蜴身上得到证实。最近的研究表明，蒙着面纱的变色龙（Chamaeleo calyptratus）会产生生物震颤。任何通信系统的先决条件都是生物体产生和探测信号的能力。我们testedC。通过将它们放置在与振动器连接的销上，发出25,50,150,300和600hz的振动，并比较刺激前后的运动速度，来对振动做出反应。成年变色龙对50和150赫兹的频率表现出冻结反应，而幼年变色龙对50和300赫兹的频率表现出类似的反应。在第二个实验中，变色龙被诱导通过实验者接触产生生物震颤。这些生物震颤的平均基频为106.4至170.3赫兹，持续时间为0.06至0.29秒。总体而言，确定了两类生物震颤，“hoots”和“mini-hoots”，其平均相对信号强度（分别为- 7.5和- 32.5 dB）差异显著。2个月大的幼年变色龙能够产生生物震颤，这表明这种行为可能在个体发育过程中具有广泛的生态功能。总的来说，数据表明c。Calyptratuscan产生和检测生物震颤，可用于种内交流。
Biotremors are vibrations, usually surface waves along the boundary of a medium, produced by an organism. While substrate-borne vibrations are utilized by different reptile species, true conspecific communication via biotremors has not yet been demonstrated in lizards. Recent research revealed that the veiled chameleon (Chamaeleo calyptratus) produces biotremors. The prerequisites for any communication system are the ability of an organism to produce and detect a signal. We testedC. calyptratusbehavioral responses to vibrations by placing them on a dowel attached to a shaker, emitting vibrations of 25, 50, 150, 300, and 600 Hz and compared their locomotory velocity before and after the stimulus. Adult chameleons exhibited a freeze response to 50 and 150 Hz, while juveniles exhibited a similar response to frequencies between 50 and 300 Hz. In a second experiment, chameleons were induced to produce biotremors via experimenter contact. These biotremors ranged in mean fundamental frequency from 106.4 to 170.3 Hz and in duration from 0.06 to 0.29 s. Overall, two classes of biotremors were identified, “hoots” and “mini-hoots,” which differed significantly in mean relative signal intensity (−7.5 and −32.5 dB, respectively). Juvenile chameleons 2 months of age were able to produce biotremors, suggesting this behavior may serve a wide range of ecological functions throughout ontogeny. Overall, the data demonstrate thatC. calyptratuscan both produce and detect biotremors that could be used for intraspecific communication.
