在2011年、2012年和2013年，我们在日本东部的潮间带调查了伴随2011年东日本大地震和海啸的福岛第一核电站严重事故的生态影响。潮间带物种的数量随着距离发电厂的距离的减小而显著减少，2012年，从广野到双叶海滩（距离约30 km），在发电厂附近没有采集到岩壳（Thais clavigera）标本。在许多其他遭受海啸袭击的地点收集的岩石外壳标本表明，2012年核电站周围没有岩石外壳可能是由2011年的核事故造成的。2013年的定量调查显示，潮间带的物种数量和种群密度在工厂附近或以南几公里内的地点比其他地点低得多，低于1995年，特别是节肢动物。这些发现没有明确的解释，但很明显，自核事故以来，发电厂周围的潮间带生物群受到了影响。
In 2011, 2012, and 2013, in the intertidal zones of eastern Japan, we investigated the ecological effects of the severe accident at the Fukushima Daiichi Nuclear Power Plant that accompanied the 2011 Great East Japan Earthquake and Tsunami. The number of intertidal species decreased significantly with decreasing distance from the power plant, and no rock shell (Thais clavigera) specimens were collected near the plant, from Hirono to Futaba Beach (a distance of approximately 30 km) in 2012. The collection of rock shell specimens at many other sites hit by the tsunami suggests that the absence of rock shells around the plant in 2012 might have been caused by the nuclear accident in 2011. Quantitative surveys in 2013 showed that the number of species and population densities in the intertidal zones were much lower at sites near, or within several kilometers south of, the plant than at other sites and lower than in 1995, especially in the case of Arthropoda. There is no clear explanation for these findings, but it is evident that the intertidal biota around the power plant has been affected since the nuclear accident.
