在整个动物界，求偶展示的多样性是巨大的，展示的范围从看似简单到令人难以置信的复杂。信号者通常对接收器中针对特定感觉通道的信号具有复杂的形态适应。在某些情况下，这些信号对人类观察者来说是如此令人信服，以至于忽略了重要信号存在于其他感觉形式中的可能性，潜在地导致了对通信系统的不完整描述。跳蛛(跳蛛科)具有非凡的视觉能力。然而，有一种物种，哈伯罗纳特斯多斯森，最近被证明具有复杂的多分量地震求偶信号，以及与其多个视觉装饰物和运动展示相一致的产生。在这里，我们通过比较不同实验处理的交配频率，证明了这些地震信号在多氏沼泽夜蛾求偶过程中的重要性。处女与来自两个试验组之一的雄性配对：非哑巴雄性或哑巴雄性。我们发现，与沉默的雄性相比，雌性更有可能与非沉默的雄性交配。此外，在所有交配的配对中，非静音配对的交配潜伏期显著短于静音配对，交配前食人率显著低于非静音配对。这些结果表明，地震信号是雄鱼求偶行为的重要组成部分。此外，我们证明了许多其他哈伯龙特斯物种在它们的求偶显示中包括各种地震信号，并讨论了潜在的选择压力，这些选择压力可能推动多模式显示的进化，即使在已经对针对一种感觉通道的信号具有复杂的形态适应的物种中也是如此。(C)2004年，动物行为研究协会。爱思唯尔有限公司出版。保留所有权利。
The diversity of courtship displays throughout the animal kingdom is immense and displays can range from seemingly simple, to incredibly complex. Signallers often possess elaborate morphological adaptations for signals directed at a specific sensory modality in receivers. In some cases, these signals are so compelling to human observers, the possibility that important signals exist in other sensory modalities is ignored, potentially resulting in an incomplete characterization of the communication system. Jumping spiders (Salticidae) have remarkable visual capabilities. Yet one species, Habronattus dossenus, has recently been shown to have a complex repertoire of multicomponent seismic courtship signals in addition to and produced in concert with its multiple visual ornaments and movement displays. Here, we demonstrate the importance of these seismic signals in the courtship display of H. dossenus by comparing mating frequencies across experimentally manipulated treatments. Virgin females were paired with males from one of two experimental groups: nonmuted males or muted males. We found that females were significantly more likely to copulate with nonmuted males than with muted males. Furthermore, in all pairs that copulated, the latency to copulation was significantly shorter in nonmuted pairings than in muted pairings and precopulatory cannibalism rates were significantly lower. These results demonstrate that seismic signals are a critical component of male H. dossenus courtship displays. Additionally, we demonstrate that many other Habronattus species include a diversity of seismic signals in their courtship displays and we discuss potential selection pressures that may drive the evolution of multimodal displays even in species that already possess elaborate morphological adaptations for signals directed at one sensory modality.
