【摘要】 硅藻是海洋浮游植物的主要类群,也是海洋生态系统中的主要初级生产者,在海洋生态系统的物质循环和能量流动中起着极其重要的作用,但人们对海洋硅藻多样性和生态作用的认识还很有限.在叙述海洋硅藻多样性、生态作用及硅藻分类学与系统学的国内外研究动态和最新进展的基础上,概述了厦门大学硅藻课题组近年来在海洋硅藻分类学与系统学、多样性与生态分布、硅藻数据库与计算机自动识别、微型硅藻与硅藻隐形种、硅藻遗传地理差异、硅藻对环境和气候变化的响应机制、硅藻细胞硅吸收与硅质壁形成机制等方面的主要研究进展和取得的主要成果.更多还原

【Abstract】 Diatom is a dominant member of marine phytoplankton and is important primary producer in marine ecosystem which plays a very significant role in the chemical cycle and energy flow in marine ecosystem.However,our knowledge on diversity and ecological role of marine diatoms is insufficient compared to the great numbers of unknown diatom species.In this paper,a review is made on the progress in research of biodiversity,ecology and taxonomy of marine diatoms.As a contribution to the 90th anniversary of Xiamen University,the mostly research progress on marine diatoms by Diatom Laboratory,Xiamen University is also presented in the paper.Our recent studies include diatom taxonomy,systematics,diversity and ecology,marine diatom database and automatic identification,nano-diatom species and cryptical species,genetic difference and phylogeny of red-tide diatoms,response of diatoms to climate change,and diatom silica mineralization and vale formation mechanism.更多还原
