中国红树林区的耳螺

Ellobiid molluscs of Chinese mangrove habitats

耳螺是一类特殊的原始有肺类软体动物,主要分布于热带、亚热带海陆交汇区的高潮带和潮上带。耳螺在红树林区广泛分布,且资源非常丰富,全世界已知的约240种耳螺中,至少有一半以上的种类在红树林区被记录。本文总结了耳螺与红树林的关系以及中国嗜盐耳螺的种类,综述了红树林区耳螺的种类组成、分布、生态功能、行为等的研究进展,报道了中国大陆红树林耳螺种类组成和分布特点,中国共有嗜盐耳螺11属59种(附录I),其中9属42种分布于红树林区,包括21个新记录种。提出了耳螺对环境变迁和人为干扰十分敏感,可作为海堤建设对红树林影响的重要指示物种,是未来的重要研究方向之一。

The family Ellobiidae is a special group of primitive pulmonate molluscs that live in tropical and subtropical areas,mainly in high tidal and supratidal zones of coastal areas.Ellobiids occur widely and abundantly in mangrove areas.Of the 240 species known globally,over half of them have been recorded in mangrove habitats.In this paper,we summarize species of halophilic ellobiids in China and the relationship between ellobiids and mangroves.We discuss the achievements of mangrove ellobiids studies in the fields of species composition,distribution,ecological function and behavior.We also report a complete list of the el-lobiid species from mangroves and their distribution within China's Mainland,including 21 newly recorded species.It is implied that this group is very sensitive to environmental changes and human disturbances,therefore it can be used as a bio-indicator for sea dike construction,which is an important proposed research topic in future.
