How vocal organisms share acoustic space has primarily received attention in terrestrial environments. Comparable studies in marine environments, however, remain rare. By recording sounds on a coral reef in French Polynesia for 48 h and 24 h, this study provides first insights on how different sound types are distributed within the acoustic space and may create acoustic niches optimizing acoustic communication within a highly diverse community containing numerous soniferous fish species. Day-time was dominated by two to six sound types, while recordings performed at night revealed a more diverse vocal community made of up to nineteen sound types. Calling activity was distributed over time allowing each sound type to dominate the soundscape sequentially. Additionally, differences in the acoustic features of sounds occurring during the same period were observed. Such partitioning in time and acoustic spaces would reduce potential overlaps of sounds produced by vocal species living in sympatry in coral reefs.

当地的声波活动揭示了珊瑚礁鱼类群落中的潜在分隔。

在陆地环境中，声带生物如何共享声空间已受到广泛关注。然而，在海洋环境中进行可比的研究仍然很少。通过在法属波利尼西亚的珊瑚礁上记录声音48小时和24小时，这项研究提供了关于不同声音类型在声学空间中的分布方式的初步见解，并且可以创建声学小生境，从而在包含众多声母鱼的高度多样化的社区内优化声学交流。种类。白天有2到6种声音类型占主导地位，而夜间录制的录音则揭示了由多达19种声音类型组成的更加多样化的人声社区。通话活动随时间分布，从而使每种声音类型都能顺序主导音景。另外，观察到在同一时期发生的声音的声学特征上的差异。这种在时间和声音空间上的划分将减少生活在珊瑚礁共生体中的有声物种产生的声音的潜在重叠。
