The rise in species richness with area is one of the few ironclad ecological relationships. Yet, little is known about the spatial scaling of alternative dimensions of diversity. Here, we provide empirical evidence for a relationship between the richness of acoustic traits emanating from a landscape, or soundscape richness, and island area, which we term the SoundScape‐Area Relationship (SSAR). We show a positive relationship between the gamma soundscape richness and island area. This relationship breaks down at the smallest spatial scales, indicating a small‐island effect. Moreover, we demonstrate a positive spatial scaling of the plot‐scale alpha soundscape richness, but not the beta soundscape turnover, suggesting a direct effect of species on acoustic trait diversity. We conclude that the general scaling of biodiversity can be extended into the realm of ecoacoustics, implying soundscape metrics are sensitive to fundamental ecological patterns and useful in disentangling their complex mechanistic drivers.

将物种-区域关系扩展到生态声学领域：声景-区域关系


物种丰富度随面积的增加是为数不多的坚不可摧的生态关系之一。然而，人们对多样性的替代维度的空间尺度知之甚少。在这里，我们提供了经验证据，证明景观发出的声学特征的丰富度或声景丰富度与岛屿区域之间的关系，我们称之为 SoundScape-Area 关系 （SSAR）。我们展示了伽马声景丰富度与岛屿面积之间的正相关关系。这种关系在最小的空间尺度上被打破，表明存在小岛效应。此外，我们证明了地块尺度 alpha 声景丰富度的正空间尺度，但 beta 声景周转率没有，这表明物种对声学特征多样性有直接影响。我们得出的结论是，生物多样性的一般规模可以扩展到生态声学领域，这意味着声景指标对基本的生态模式很敏感，并有助于解开它们复杂的机制驱动因素。
