查询词典 zooplankton

Under oligotrophic conditions, a phytoplankton size of 10 μm3 combined with a zooplankton size of 101.25 μm3 to give the maximum value of the ascendency.

在贫养条件下，浮游植物大小10 μm3加上浮游动物大小101.25 μm3给予最大价值的优势。

Grazing of phytoplankton by zooplankton and suspension-feeding benthos is also considered a promising control agent, but this approach has many logistical problens and is a long way from the application stage.

另一方面，利用大型海藻与微藻间的相生相克和营养竞争等作用在养殖区域内进行赤潮的防控被认为具有较强的理论和实践意义。

Trophic components involved were milkfish, zooplankton, phytoplankton, chironomid larvae, benthic algae, supplemental feed and detritus.

In two basins, Bohai and Qinglian, Rotifera contributed most to biomass in almost each size class, followed by copepod. Both the size range of the zooplankton and the body size at which peak biomass occurred were lower than in temperature lakes.

根据对两个子湖一一波海湖和青莲湖2002年和2003年生物量分布的分析与比较，2003年生物量均有所下降，在生物量分布的每个体重等级上轮虫基本上都是第一优势类群，其次是桡足类。

In the pelagic subsystem,there are 4biological state variables which were represented by functional groups:flagellate,diatom,pelagic bacteria and zooplankton.In the benthic subsystem,there were 5 biological state variables represented also by functional groups:macrobenthos,meiobenthos,aerobic and anaerobic bacteria,and shrimp-which is actually epibenthos.

将浮游亚生态系又划分为4个功能群，分别为：鞭毛藻、浮游硅藻、水体中细菌和浮游动物，将底栖亚生态系划分为5个功能群，分别为大型底栖动物、小型底栖动物、底栖厌氧菌、底栖好氧菌，对于营底上生活的对虾也划分在这一亚生态系中予以考虑。

The phytoplankton community was mainly composed of Cyanophyceae, Euglenophyceae, Bacillariophyceae, and Chlorophyceae, and the dominant species were Oscillatoria subtillissima, Dactylococcopsis irregularis, Euglena caudata, Melosira granulata, Cyclotella meneghiniana, Chlorella vulgaris, and Scenedesmus quadricauda. The main environmental factors affecting the distribution of phytoplankton species in July were ammonium-nitrogen, dissolved oxygen, water temperature, and total phosphorus, while those in September were pH, water temperature, dissolved oxygen, transparency, and total nitrogen. Water transparency and zooplankton were the main factors affecting the biomass of Cryptophyceae, Pyrrophyceae, and Bacillariophyceae; while nitrogen, phosphorous, and dissolved oxygen were the main factors affecting the biomass of Cyanophyceae, Euglenophyceae, and Chlorophyceae.

结果表明：调查期间共鉴定出浮游植物384种，隶属于8门，浮游植物密度范围为2.01×105～57.60×105 cells·L-1；群落组成以蓝藻、裸藻、硅藻和绿藻为主，主要优势种有细微颤藻、无常蓝纤维藻、尾裸藻、颗粒直链藻、梅尼小环藻、普通小球藻、四尾栅藻等；7月影响浮游植物分布的主要环境因子依次为铵态氮、溶解氧、水温和总磷，而9月的pH值、水温、溶解氧、透明度和总氮含量对浮游植物的分布产生影响较大；其中，透明度和浮游动物量是影响隐藻、甲藻和硅藻藻类生物量的主要环境因子，而蓝藻、裸藻、绿藻主要受水体氮磷营养盐浓度和溶解氧的影响。
