硅藻类

科学家们发现一些抗菌肽有些特性与贝壳蛋白很相似，这些蛋白来自于来自硅藻类，微水藻和那些符合条件有保护性质的海洋产物。

The scientists discovered that some AMPs have properties similar to a shell-building protein derived from marine diatoms , microscopic algae , and that these protective properties may fit the bill .

浮游植物有5门16科21属48种（变种和变型），浮游植物平均细胞密度为22.46×103个/dm3，其中以硅藻类占优势（84.51%）。

A total of 48 taxa belonging to 21 genera of phytoplankton in the sea area were identified . The average cell density of phytoplankton was 22.46 × 103 cells / dm3 , of which diatoms were predominant ( 84.51 % ) .

硅（Si）作为重要的生源要素，对水环境中硅藻类浮游植物的初级生产力具有不可替代的作用。

Silicon ( Si ), as an important biogenic element , acts an irreplaceable role on the primary production of larger phytoplankton such as diatoms .

鉴定浮游植物种类54属184种（含变种和变型），其中暖水种为140种（占76.5%）.硅藻类和甲藻类等浮游植物的平均总细胞密度为198.71×102个／m3；

A total of 184 phytoplankton species which belong respectively to 54 genera is identified . Most of those species recorded belonged to warm water forms ( accounted for 76 . 5 % ) .

硅藻类的营养细胞是二倍体，它是由配子融合直接产生的。

In diatoms the vegetative cells are diploid , and are formed directly by the fusion of gametes .

经典食物链理论认为，硅藻桡足类鱼类是海洋生态系统物质循环和能量流动的主要途径。

' Diatoms - copepod-fisher ' was the main way for material cycle and energy flow in classic marine food chain of marine ecosystem .

但目前现场、室内实验结果不一：室内实验结果显示硅藻对桡足类繁殖的抑制作用主要是因为缺乏必要的多不饱和酸（PUFAs）。

It still can not find agreements between the laboratory and in situ works . The results from laboratory indicated that the inhibitory effect caused by diatom could be due to deficiency of some polyunsaturated acids ( PUFAs ) .

底栖硅藻是多数腹足类食物来源的相当重要组成部分。

Benthic diatoms are an important fraction of the food for most of gastropods .

因此，在这一海区存在发生高浓度硅藻对桡足类抑制作用的可能性，是开展硅藻&桡足类相互作用研究的理想场所。

It is possible of diatoms in high concentration inhibiting the reproduction of copepods in this sea area , where is the ideal sites to study on diatoms - copepod interaction .

近年来，许多现场和实验室研究表明：作为桡足类主要食物来源的硅藻对桡足类的繁殖、生长和发育具有抑制作用。

In recent years , many studies have shown that : diatoms , considered as the main food source for copepods , induced inhibitory effects on reproduction , growth and development of copepods .
