PAM已被证明是监测海洋、陆地和水生生物声景的有效工具。最近有人提出，它也可能是监测土壤动物的一种有效方法，但迄今为止只在温带和极地地区的四项研究中使用过。我们提出了热带森林土壤声景观的第一个研究，使用了一种新的分析管道，允许在最小土壤干扰下使用声景观的原位记录。我们发现了燃烧森林和未燃烧森林在土壤声景观上的显著差异，以及土壤声景观中死亡循环的第一个迹象。这些有希望的结果和方法上的进步突出了PAM在大规模和长期监测土壤生物多样性方面的潜力。我们利用这些结果讨论了研究重点，包括土壤生物学与生物多样性、群落结构和生态系统功能的关系，以及适当的硬件和分析技术的使用。
PAM has proven to be an effective tool for monitoring biotic soundscapes in the marine, terrestrial, and aquatic realms. Recently it has been suggested that it could also be an effective method for monitoring soil fauna, but has so far been used in only four studies in temperate and polar regions. We present the first study of soil soundscapes in tropical forests, using a novel analytical pipeline allowing for the use of in-situ recording of soundscapes with minimal soil disturbance. We found significant differences in soil soundscapes between burnt and unburnt forests and the first indications of a diel cycle in soil soundscapes. These promising results and methodological advances highlight the potential of PAM for large-scale and long-term monitoring of soil biodiversity. We use the results to discuss research priorities, including relating soil biophony to biodiversity, community structure and ecosystem functioning, and the use of appropriate hardware and analytical techniques.
