浮石是一种非常有效的漂流剂，可以大大增加各种海洋生物的扩散范围，并将孤立的浅海和沿海生态系统连接起来。在这里，我们报告了一个重要的最近浮石漂流和长距离扩散事件发生在西南太平洋后，2006年在汤加的家礁火山爆发。我们已经限制了转移的轨迹、速度、生物量和生物多样性，发现了80多个物种和大量的生物量在7-8个月内经历了超过5000公里的旅程。不同的微环境条件的浮岩，造成相对稳定的碎屑在海面上，促进生物招聘的多样性。我们的研究结果强调浮石漂流作为一个重要的过程，促进海洋生物的分布，这对殖民过程和成功，敏感的海洋环境的管理，和入侵的害虫物种的影响。
Pumice is an extremely effective rafting agent that can dramatically increase the dispersal range of a variety of marine organisms and connect isolated shallow marine and coastal ecosystems. Here we report on a significant recent pumice rafting and long-distance dispersal event that occurred across the southwest Pacific following the 2006 explosive eruption of Home Reef Volcano in Tonga. We have constrained the trajectory, and rate, biomass and biodiversity of transfer, discovering more than 80 species and a substantial biomass underwent >5000 km journey in 7-8 months. Differing microenvironmental conditions on the pumice, caused by relative stability of clasts at the sea surface, promoted diversity in biotic recruitment. Our findings emphasise pumice rafting as an important process facilitating the distribution of marine life, which have implications for colonisation processes and success, the management of sensitive marine environments, and invasive pest species.
