几种树蛙（雨蛙科）的广告呼叫的声学特性的变化模式与女性对这些相同属性的偏好模式有关。属性被明确分类为静态或动态的基础上内的男性变异性在回合的呼叫。静态属性是高度定型的男性和男性之间的自然种群。动态特性往往改变多达100%，在单回合的呼吁，动态特性通常是更多变的男性在自然种群中比静态特性。在繁殖季节的过程中，个别男性的呼叫性能的分析表明，至少有一个动态特性，脉冲数（或呼叫持续时间）inHyla versicolor，是足够的可重复性，以区分男性。采用合成呼叫的回放实验表明：（1）女性表现出的偏好模式应导致选择，即稳定或弱方向性的静态属性，和高度方向性的动态属性;和（2）信号的整体吸引力受到影响的变化在静态和动态属性。在对其他分类群，主要是无尾两栖类和昆虫的实验室和实地研究中也发现了类似的结果。呼叫属性的男性和女性的偏好的变化模式进行了讨论，在近端的机制和理论模型的演变女性的选择。
Patterns of variation in the acoustic properties of advertisement calls of several species of treefrogs (family Hylidae) are related to patterns of female preferences for these same properties. Properties were unequivocally classified as static or dynamic based on within-male variability during bouts of calling. Static properties are highly stereotyped within males and between males in natural populations. Dynamic properties often change by as much as 100% during single bouts of calling; dynamic properties are usually much more variable among males in natural populations than are static properties. An analysis of the calling performance of individual males over the course of a breeding season indicated that at least one dynamic property, pulse number (or call duration) inHyla versicolor, was sufficiently repeatable to differentiate between males. Playback experiments that employed synthetic calls showed that: (1) females exhibit patterns of preferences that should result in selection that is stabilizing or weakly directional on static properties, and highly directional on dynamic properties; and (2) the overall attractiveness of a signal is affected by variation in both static and dynamic properties. Similar results were found in laboratory and field studies of other taxa, primarily anurans and insects. Patterns of variability in call properties of males and in female preferences are discussed in terms of proximate mechanisms and theoretical models of the evolution of female choice.
