Although many bdelloids live in desiccation-prone habitats, such as ephemeral ponds, there are substantial numbers found in permanently aquatic habitats that are unable to desiccate.

尽管许多轮虫生活在干燥的栖息地，如短时间的小水塘，但是有许多轮虫却生活在不会干涸的多水环境里。

The rotifer Habrotrocha sp. is a common and useful microfauna in biological wastewater treatment. This study used disinfectants to set up a bacteria-free culture system of Habrotrocha sp.

以污水生物处理中一种常见的有益微型动物——宿轮虫为对象，进行了应用消毒剂建立宿轮虫的无菌培养系的方法学研究。

More and more studies have been carried out on population genetic structure of rotifer population and gene flow by molecular technologies to assess the effect of cyclic parthenogenesis and resting egg bank on rotifer's genetics and evolution.

由于循环孤雌生殖和休眠卵库的存在，使得轮虫种群内的遗传变异和种群间基因流模式有别于其他动物。目前，国外有关轮虫分子遗传和进化的研究还刚刚起步，国内还没有这方面的报道。

At 20℃, 25℃and 30℃, the percentage of mictic females in the offspring of the four rotifer clones was significantly different, and that of Clone C was the highest.

在四个温度(15℃、20℃、25℃和30℃)下对四个克隆萼花臂尾轮虫的后代质量及其与温度、轮虫个体大小和卵大小等之间的关系进行了研究。

After just seven days of blowing around, there were as many fungus-free rotifer populations as there were after three weeks of dehydration without wind.

在第二轮试验中，威尔逊把受感染的轮虫放在一个风室里，他们观察到这些轮虫可以不带真菌的飘开，繁殖出不受寄生虫侵害的后代。7天以后，他们的数量就和没有风脱水以后三星期后的数量一样多了。

This is different from previous researches, in which long-distance founder effect is the main force of phylogeography of rotifer population.

各湖泊隔离年代比较短，不同湖泊轮虫种群之间扩散强度大，轮虫休眠卵库的存在，以及近几十年来各湖泊环境条件变化可能是造成"有时滞基因流"产生的原因。

Polyarthra trigla is a predominant rotifer in Donghu lake, Wuhan.

针簇多肢轮虫是武汉东湖的优势轮虫，1983，5—1984，4在Ⅰ，Ⅱ站分别测定了这种轮虫卵和种群密度。

However, the growth of rotifer fed on high-density Chlorella pyrenoidosa was inhibited notably, and there was no effect on its fecundity. Sexual reproduction of Brachionus urceus was not promoted by improving the density of diet.

结论］低食物浓度下，轮虫生命周期缩短、繁殖力降低；食物浓度过高，能抑制轮虫生长，但对繁殖力影响不大；提高食物浓度，对壶状臂尾轮虫的有性生殖没有明显的促进作用。

The values of EAAI in rotifer and nauplii of Artemia were all above 90 for different larval stages of Scylla serrata. It was suggested that rotifer and nauplii of Artemia may satisfy the nutritive requirement of larval Scylla serrata for amino acids in diet protein.

对于各期幼体，饵料轮虫和卤虫无节幼体的必需氨基酸指数均大于90，可以认为，轮虫和卤虫无节幼体能够满足锯缘青蟹幼体对饵料中必需氨基酸的营养需求。

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。
