A novel indicator of coastal environment in the Kuroshio Current region: Estimation of intertidal degradation by coenocytic green algae and coutermeasures for its propagation

通过沿着日本、台湾和菲律宾黑潮海区的社会生态调查、实验室培养和生物地理学研究，探讨了多核绿色藻类（CGA）作为海岸环境退化指示物的可用性。蕨藻属在整个研究区域普遍生长，Valonia spp.被认为是合适的培养实验，两者都很容易检测到的自然种群。这些观察结果表明，它们可能是有用的环境指标。在台湾绿岛的案例研究中，一个贫穷的植被的CGAs被发现符合一个局部的退化造成的沿海环境缺乏一定的社会基础设施。

Availability of coenocytic green algae (CGAs) as an indicator of coastal environment, which has been degraded significantly, was examined by social and ecological survey along the Kuroshio current region of Japan, Taiwan and Philippines as well as culture experiments and bio-geographical studies in laboratory. Caulerpa spp. were commonly growing throughout the study areas, Valonia spp. were found to be suitable for culture experiments, and both were easily detectable in the natural populations. These observations suggested that they are potentially useful as an environmental indicator. In the case study in Green Island of Taiwan, a poor vegetation of the CGAs was found to coincide with a localized degradation of coastal environment caused by the lack of certain social infrastructures.
