【摘要】 某些甲藻在面对不良环境时,机体会采取一定的措施——失去鞭毛、积累营养物质形成甲藻包囊沉入水层底部,一旦周围环境适宜,沉积物中甲藻包囊便可以萌发形成营养细胞再次进入水体.甲藻包囊的大量萌发极易形成甲藻优势种爆发,进而出现有害藻华现象.作为甲藻生活史中的一个重要阶段,包囊对甲藻种群的生存与发展具有重要的作用.甲藻包囊组成与分布可以间接反映一段时期内上层水体的营养状况,继而推测出调查海域是否有藻华爆发的潜在威胁.本文主要阐述了甲藻包囊的基本形态分类和术语,甲藻包囊沿革及其国内外研究现状,并对甲藻包囊与上层水体浮游植物的相互关系进行讨论.更多还原

【Abstract】 Some dinoflagellates in poor environmental conditions lose their flagella,so as to accumulate nutrients in cells,and finally,consequently conduct to form dinocyst(dinoflagellates cysts).Once the water conditions are available,these dinocysts will germinate and thrive in waters again.As a consequent result,the dominant dinoflagellate species will form a dinoflagellate bloom.As an important stage in the life cycle of dinoflagellates,the dinocysts play an important role in their survival and development.As an indication of the nutrients depletion in the upper layers water,the dinocysts can help us to speculate the potential threaten as precursor of the harmful algal blooms(HABs).This paper mainly discusses on the morphology,classification and terms used for dinocysts,as well as their evolution routes and the status of dinocysts studies both at home and abroad.We also summarize the relationship between dinocysts and their co-occurring upper water phytoplankton assemblages.更多还原
