Physiological tolerances in species in addition to ecological tolerance for disturbance in interspecific interactions act as key elements for restoration of a whole island ecosystem. In an effort to study these community recovery processes, we aim to identify the key elements on a seed dispersal system and estimate these ecological tolerance on a volcanic island, Miyake-jima, which experienced an eruption in the summer of 2000. In the results, seeds of Eutya japonica were found most frequently in bird feces and Japanese white-eye was the dominant visitor, comprising 75% of all visits to fruiting Eurya trees. The genetic diversity of Eurya seeds in bird feces were not correlated with index of volcanic damages. The results indicated that the seed-dispersal system of E. japonica and White-eye was maintained under volcanic disturbance and act as important elements for forest restoration.

除了对种间相互作用的生态耐受性外，物种的生理耐受性是恢复全岛生态系统的关键要素。为了研究这些社区恢复过程，我们旨在确定种子分散系统的关键要素，并估算在火山岛Miyake-jima上的这些生态耐受性，该岛屿在2000年夏季爆发。 Eutya Japonica的种子在鸟粪中最常发现，日本白眼是主要的访客，占果实埃里亚树木的所有访问的75％。鸟粪中埃里亚种子的遗传多样性与火山破坏指数无关。结果表明，在火山干扰下，将大肠杆菌和白眼的种子挖出系统保持在森林恢复中的重要因素。
