Calyciforus in Donghu Lake. The reproductive pattern of parthenogenesis provides the species cloning matrilineally, and keeping the most parental mutations.

东湖作为一个中型湖泊，其环境条件的季节变化是可以预测的，因此萼花臂尾轮虫休眠卵的产生是有一定规律的。

Two species of algae, Chlorella pyrenoidosa and Scenedesmus obliquus were cultured by the method of Li Shanghao's .

采用种群累积培养法，研究了藻类食物的种类和密度对萼花臂尾轮虫休眠卵形成的影响。

The effect of temperature on the population growth of Brachionus calyciflorus from the Nanhu Lake was studied at 15, 25 and 35℃ by population accumulative culture. The rotifer was fed with Scenedesmus obliquus at a concentration of 5.0×10^5 cells/mL.

应用群体累积培养法，以浓度为5.0×l0^5 cells/mL的斜生栅藻为食物，研究了温度（15、25和35℃）对南湖水体萼花臂尾轮虫种群增长的影响。

The annual dynamics of Brachionus populations in Lake Jinghu of Anhui Province, China was studied in the year 2003, and the relationships between their body volumes, egg volumes as well as relative egg volumes and the ecological factors including water temperature, Chl-a concentration were regressively analyzed.

对镜湖臂尾轮虫种群的周年动态进行了研究，测量和分析了它们的个体大小、卵大小和相对卵大小及其与水温和叶绿素a浓度等生态因子间的关系。

The filtering and feeding rate of rotifer Brachionus urceus were studied under different temperature,salinity,food species,pH and light.

研究了壶状臂尾轮虫在不同的温度、盐度、饵料种类、pH和光照条件下滤水率和摄食率的变化情况。

The effect of food concentration on characteristics in life history of Brachionus urceus, such as the duration of principal development stage, net reproductive rate and mixis rate in all the offspring, was studied by the method of clonal culture.

方法］采用单个体培养法，研究了不同浓度的蛋白核小球藻对壶状臂尾轮虫主要发育阶段历时、净生殖率以及全部后代的混交雌体百分率等生活史特征的影响。

At the experimental intensity of 20W/cm^2 and in the dose range studied (0.00, 0.24, 0.48, 0.72, 0.96 and 1.20kJ/m^2), both the population number and growthrate was the highest in the control and decreased with the increment of UV-B radiation. In addition, the population number and growth rate of rotifer Brachionus urceus showed a similar tendency of decrease with the dose increase of UV-B radiation. Both of them could be used as an ideal biomarker for the enhancement of UV-B radiation.

实验表明，在本实验辐射强度(20W/平方公分)和剂量范围内（0.24、0.48、0.72、0.96和1.20kJ/平方人公尺）壶状臂尾轮虫的种群数量和种群增殖率均以对照组最高，各UV-B辐射处理组则随UV-B辐射剂量的增大而呈一致性减小，说明该种群的种群数量和种群增殖率随UV-B辐射的增强显示一致性的影响，两者都可以作为大气UV-B辐射强弱的生物指标。

The effects of aldrin and dieldrin on the reproduction of B.

以17β-雌二醇为阳性对照，运用生命表技术和群体累积培养方法，评价了艾氏剂和狄氏剂对萼花臂尾轮虫生殖的影响。

The control lines continue aft through the fuselage bulkheads to the tail wheel, hook, trim tabs and stabilizer control surfaces.

控制线继续尾部通过机身舱壁向尾轮，钩，修剪标签和稳定控制面。

The relationship of three Brachionus calyciflorus morphotypes (two short-spined, single-spined and spineless ones) was studied in the laboratory.

在实验室条件下研究了萼花臂尾轮虫3种形态型(双短侧棘刺、单短侧棘刺和无侧棘刺)个体之间的关系。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
