海洋浮游纤毛虫包囊的研究进展*

作为微型浮游动物的重要组成部分,海洋浮游纤毛虫是连接微食物环和经典食物链的重要中介。有些浮游纤毛虫在生活周期中会形成包囊,条件适宜时包囊会萌发,这对纤毛虫种群动态有重要的意义。目前国际上对于浮游纤毛虫生态学的研究主要集中在其营养期细胞,浮游纤毛虫包囊的研究尚少,中国还没有这方面的研究。本文对浮游纤毛虫包囊研究进展进行概述,包括包囊的形态、沉积物中包囊的丰度、包囊形成的环境因素、包囊萌发过程及环境因素对包囊萌发的影响等方面,希望对国内开展浮游纤毛虫包囊的研究有所裨益。

Cysts of marine planktonic ciliates: A review

As one of the important components of microzooplankton, marine planktonic ciliates serve as a crucial link between microbial food web and classical food chain. Some planktonic ciliates in their life cycle can encyst, and can excyst when environment is favorable. The encystment and excystment cycle is very important to the planktonic population dynamics in water column. Though the vegetative stage of planktonic ciliates has been frequently studied, the resting phase is largely ignored. In China, we do not even begin research in this field. This paper reviewed the progress in cyst research, including cyst morphology, cyst abundance, environmental parameters of cyst formation, cyst development during excystment, and excystment in relation to environmental parameters, which could be helpful to promote the study of the cysts of marine planktonic ciliates in China.
