这项研究扩展了最近的研究，表明面纱变色龙（Chamaeleo calyptratus）可以产生和检测生物震颤。变色龙在不同的社会背景下配对：支配（男性-男性;女性-女性）。calyptratus）;求偶（male-femaleC. calyptratus）;异种（C. calyptratus + C. gracilis）和大小级间优势（成年+幼年C. calyptratus）。同时使用视频和加速度计记录它们的行为，共记录了398个生物震颤。Chamaeleo calyptratus主要在同种优势和求偶背景下产生生物震颤，占记录到的生物震颤总数的84.7%，生物震颤的产生在个体之间差异很大。Biotremors引起的视觉接触与另一个同种或异种，和试验中，变色龙表现出视觉显示和侵略行为更有可能记录biotremors。三类生物震颤被确定的鸣叫，迷你鸣叫，隆隆声，这在基本频率，持续时间和相对强度显着不同。生物震颤频率随信号持续时间的增加而降低，频率调制是明显的，尤其是在猫头鹰。总的来说，数据显示C.帽藻在同种和可能的异种相互作用期间利用基质传播的振动通信。
This study extends recent research demonstrating that the veiled chameleon (Chamaeleo calyptratus) can produce and detect biotremors. Chameleons were paired in various social contexts: dominance (male–male; female–femaleC. calyptratus); courtship (male–femaleC. calyptratus); heterospecific (C. calyptratus + C. gracilis); and inter-size class dominance (adult + juvenileC. calyptratus). Simultaneous video and accelerometer recordings were used to monitor their behavior and record a total of 398 biotremors.Chamaeleo calyptratusproduced biotremors primarily in conspecific dominance and courtship contexts, accounting for 84.7% of the total biotremors recorded, with biotremor production varying greatly between individuals. Biotremors were elicited by visual contact with another conspecific or heterospecific, and trials in which chameleons exhibited visual displays and aggressive behaviors were more likely to record biotremors. Three classes of biotremor were identified—hoots, mini-hoots, and rumbles, which differed significantly in fundamental frequency, duration, and relative intensity. Biotremor frequency decreased with increasing signal duration, and frequency modulation was evident, especially in hoots. Overall, the data show thatC. calyptratusutilizes substrate-borne vibrational communication during conspecific and possibly heterospecific interactions.
