在实验室条件下，对13个品系褶皱臂尾轮虫的个体大小变异进行了研究。洛里卡长度范围为123 ~ 292 μm，洛里卡宽度范围为114 ~ 199 μm。从出生到成年，洛里卡长度增加了85%。操纵轮虫大小的培养条件进行了调查，为各种盐度，饮食和温度。在极端情况下，饮食和盐度产生的洛里卡长度分别为15%和11%的变化。温度×盐度×应变的析因方差分析表明，应变是决定洛里卡大小的最重要因素。
An investigation of body size variability among 13 strains of the rotiferBrachionus plicatiliswas conducted under controlled laboratory conditions. Lorica lengths ranged from 123 to 292 μm and lorica widths from 114 to 199 μm. An 85% increase in lorica length was recorded as females grew from birth to adulthood. Manipulation of rotifer size by culture conditions was investigated for various salinities, diets, and temperatures. In extreme cases, diet and salinity produced a 15% and 11% change in lorica length, respectively. A factorial ANOVA of temperature × salinity × strain effects demonstrated that strain is the most important factor determining lorica size.
