轮虫

The discovery that bdelloids can desiccate and wisp away with the wind helps resolve the mystery of their ancient asexuality and success.

蛭形轮虫可以变干而随便飘走这一发现揭示了他们古老的无性生殖方式为什么会成功的秘密。

Several significant changes were found in the composition of the rotifer, cladoceran and copepod assemblages.

许多重要的变化被发现在轮虫，枝角类和桡足类群体的组成中。

Most cladoceran abundances showed sharp declines in the presence of fish, while some rotifers, as well as their assemblage species richness, responded favourably to fish.

大多数枝角类丰度显示骤然下降当鱼类出现，然而一些轮虫，它们的群体种丰富，反映出有利的机制。

This was attributed to high population growth rates for rotifers under these ecological conditions because of reduced copepod predation on them through a trophic cascade from fish.

这个归因于轮虫在这些生态条件下的较高种群增长率，这些生态条件是由于桡足类对它们的捕食通过一个鱼类高富营养阶段。

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。

The measured composition of the communities included bacteria,fungi,algae,protozoa and some metazoa.

所研究的微型生物主要包括细菌、真菌、藻类和原生动物，此外也包括一些小型的后生动物，如轮虫等。

Currently accessible for searching are the recent mollusk files, the invertebrate paleontology files, the rotifer collection and Gary Rosenbergs molluscan species database etc.

当前可以搜寻到的信息包括新近的软体动物门文档、无脊椎动物古生物学文档、轮虫收藏以及加里罗森伯格的软体动物物种数据库等。

Acute toxicity testing method was used to study effects of different density of Prorocentrum donghaiense,Heterosigma akashiwo and Alexandrium tamarense on mortality rates and population growth parameter of Brachionus plicatilis under controlled experimental conditions.

应用急性毒性试验方法，研究了可控生态条件下不同密度的东海原甲藻、赤潮异弯藻和塔玛亚历山大藻对褶皱臂尾轮虫的致死率和种群增长参数的影响。

The high temperature and dark environment decreased the predation risk for B.

高温(30℃)和黑暗环境降低了萼花臂尾轮虫的捕食风险。

Total average quantity of Phytoplankton is 687.56×10^4ind/L, and biomass is 8.888 3 mg/L; Zooplankton belong to 4 Phylums-31 Genus or Species, protozoon and rotifer have the most quantity (77.67%), Copepoda have the most biomass (1.193 0 mg/L), total average quantity of Zooplankton is 270.690ind/L.

浮游动物共4类31个种属，数量上以原生动物、轮虫为主，占77.67%，生物量桡足类最大，为1.1930mg/L，浮游动物总平均量为270.690ind/L。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
