交通噪声是城市生境选择压力之一。由于噪声干扰声通信，许多研究表明，声信号的时间结构的变化取决于噪声。然而，通常不知道这些变化是否是适应性的，例如在嘈杂的条件下女性更容易找到变化。为了调查的现象，弯腿地蟋蟀（Dianemobius nigrofasciatus）收集了三个城市和三个农村的栖息地，饲养在一个共同的花园条件。测定了子代的雄性求偶歌和雌性求偶行为。城市男性发出了一个较高的主导频率和较短的啁啾比农村男性的呼叫歌曲。在控制噪声的情况下，雌性对城市和农村雄性歌曲的反应和定位的回放实验表明，在噪声条件下，城市和农村歌曲对雌性的择偶定位行为没有显著影响。虽然城市男性的歌声引起了女性更快的反应，但效果有限。这些结果表明，歌曲的变化是不适应的女性的选择。城市女性位于更快的歌曲在嘈杂的条件下。结果表明，适应性变化的女性交配行为发生在城市栖息地。
Traffic noise is one of the selection pressures of urban habitats. Because noise interferes with acoustic communication, many studies have shown that the temporal structures of acoustic signals change depending on the noise. However, it is often unknown whether the changes are adaptive, such as changes being more easily located by females under noisy conditions. To investigate the phenomena, bend-legged ground crickets (Dianemobius nigrofasciatus) were collected from three urban and three rural habitats and reared in a common garden conditions. Male calling songs and female mate location behaviour of the progeny were measured. Urban males emitted a calling song with a higher dominant frequency and shorter chirp than did rural males. The playback experiment of female response and localization to songs of urban and rural males, controlling for noise, showed that there were no significant effects of the song on the mate location behaviour between urban and rural songs under noisy conditions. Although the song of urban males elicited a faster response of females, the effect was limited. These results indicate the change in song is not adaptive in terms of female choice. Urban females located more quickly to song under noisy conditions. The results suggest adaptive changes in female mating behaviour occur in urban habitats.
