There is now clear evidence that climate change affects terrestrial and marine ecosystems and can cause phenological shifts in behavior. Utilizing sound to demonstrate phenology is gaining popularity in terrestrial environments. In marine ecosystems, this technique is yet to be used due to a lack of multiyear datasets. Our study demonstrates soundscape phenology in an estuary using a six-year dataset. In this study, we showed that an increase in acoustic activity of snapping shrimp and certain fish species occurred earlier in years with warmer springs. In addition, we combined passive acoustics and traditional sampling methods (seines) and detected positive relationships between temporal patterns of the soundscape and biodiversity. This study shows that passive acoustics can provide information on the ecological response of estuaries to climate variability.
现在有明确的证据表明，气候变化会影响陆地和海洋生态系统，并可能导致行为的物候学变化。在陆地环境中，利用声音来证明物候学正在变得越来越流行。在海洋生态系统中，由于缺乏多年数据集，这项技术尚未得到应用。我们的研究利用六年的数据集展示了河口的声音景观物候学。在这项研究中，我们表明，在春季较温暖的年份， snapping 虾和某些鱼类的声学活动增加得更早。此外，我们将被动声学和传统的采样方法（刺网）相结合，发现声音景观和生物多样性的时间模式之间存在正相关关系。这项研究表明，被动声学可以提供有关河口对气候变化的生态响应的信息。
