对琉球群岛沿岸群落的优势种和特征种17种海洋生物的扩散生态学进行了研究。结果表明，海南岛的红厚壳（Calophyllum inophyllum）、海刀豆（Canavalia maritima）、臭牡丹（Clerodendron inerme）、大花瓜（Guettarda speciosa）、桐花树（Hernandia索诺拉）、芙蓉（Hibiscus tiliaceus）、细叶牵牛（Ipomoea gracilis）、小花瓜（I. per-capalea、Messerschmidia argentea、露兜树、水黄皮、Scaevola frutescens、Sophora tomentosa、Terminalia catappa、Thespesia populnea、Vigna marina和Wedelia biflora。在实验室中检查了传播体的结构和大小以及它们在海水中的浮力和存活力。这17个种的传播器具有浮力的形态特征，试验表明这些种能被海流驱散。漂流线上的漂流传播者，在高潮线上的幼苗，和草本植物区的木本植物的幼苗进行了观察，丰富的琉球群岛的海岸。黑潮海流携带这些传播物从岛屿，这些物种的热带沿海植被的一部分。
The dispersal ecology of seventeen maritime species, which are dominant and/or characteristic species of coastal communities on the Ryukyu Islands, was studied. The species were Calophyllum inophyllum, canavalia maritima, Clerodendron inerme, Guettarda speciosa, Hernandia sonora, Hibiscus tiliaceus, Ipomoea gracilis, I. per-caprae, Messerschmidia argentea, Pandanus odoratissimus, Pongamia pinnata, Scaevola frutescens, Sophora tomentosa, Terminalia catappa, Thespesia populnea, Vigna marina and Wedelia biflora. The structure and size of disseminules and their buoyancy and viability in seawater were examined in the laboratory. The disseminules of these seventeen species have morphological characteristics for buoyancy, and tests showed that these species could be dispersed by sea currents. Drift disseminules on the drift line, seedlings on the high-tide line, and young plants of woody species in the herb zone were observed, being abundant on the coasts of the Ryukyu Islands. The Kuroshio Current carries these disseminules from islands where these species form part of the tropical coastal vegetation.
