本文通过分析全球超过3000种雀形目鸟类的鸣声,揭示了其鸣声可归纳为八种基本声学模式,并受生物特征、环境传播物理和生物地理历史的影响。
原文开头
Quentin Bacquelé1,2*, Jean- Yves Barnagaud2†, Cyrille Violle2, Frédéric Theunissen3, Nicolas Mathevon1,4,5† Although birdsongs are classic models for understanding the evolution of vocal communication, their global diversity has long made the development of a unifying framework challenging. By analyzing the acoustic architecture of songs from more than 3000 passerine species worldwide, we show that this acoustic space can be structured around eight elemental motifs. The differential use of these motifs is driven by a combination of species’ biological traits (social organization, morphology, and mating system) and the physics of sound propagation. In tropical rainforests, environmental filtering for transmission efficiency favors structurally simple motifs, such as flat whistles. …
