2011年3月11日，矩级9.0M的东日本大地震引发了巨大的海啸，改变了日本仙台湾太平洋沿岸近岸生态系统中的水生群落。然而，为了理解海啸影响的生态影响，对社区的连续变化及其随时间的命运进行评估是必不可少的。因此，我们在公民志愿者的帮助下，对仙台湾8个潮滩社区进行了9年的调查，并与地震前的微底栖生物组成进行了比较。结果表明，海啸造成的群落组成差异逐年减小，7年后基本消失，但有一个平坦区因海啸对环境条件的影响较大。目前的研究表明，这些潮滩群落主要受环境条件的调节，对海啸扰动具有很强的抵御能力。
The Great East Japan Earthquake, with a moment magnitude scale of 9.0M on March 11, 2011, caused huge tsunamis that altered aquatic communities in the nearshore ecosystems along the Pacific coastline of Sendai Bay, Japan. However, to understand the ecological implications of the tsunamis' impact, an assessment of the successive changes of the communities and their fate over time is essential. Therefore, we examined eight tidal flat communities of Sendai Bay with the aid of citizen volunteers over 9 years, and compared the microbenthic compositions to those before the earthquake. The results revealed that the differences in the community compositions caused by the tsunamis decreased from year to year and finally disappeared after 7 years except for one flat where the tsunamis largely changed the environmental conditions. The present study indicates that these tidal flat communities are regulated mainly by environmental conditions and are highly resilient to tsunami disturbance.
