本数据集围绕岩鹪鹩(Salpinctes obsoletus)自然鸣唱中的鸣唱类型使用偏好展开研究,测试了信号内容优化、传播效率优化及能量节约三种假设。包含12只个体的19058首鸣唱数据,每只个体鸣唱曲目库规模为52至117种,鸣唱频率差异显著。研究结果显示岩鹪鹩偏好使用长时长、低带宽、低频率及慢颤音速率的鸣唱类型。 论文“Rock wrens preferentially use song t
Species with genetically differentiated allopatric populations commonly differ in phenotypic traits due to drift and/or selection, which can be important drivers of reproductive isolation. Wedge-taile
Variation in the acoustic structure of alarm signals has mainly been viewed as coding information about the type of predator or the level of threat posed by the predator. Alarm signals can also convey
Birdsong often serves as a territorial signal, and vocal performance (the degree of vocalising close to vocal production or respiratory limits) can play a role in expressing a sender’s aggressiveness.
Animals use acoustic signals to defend resources against rivals and attract breeding partners. As with many biological traits, acoustic signals may reflect ancestry; closely related species often prod
