摘要

Eight geographic populations of Brachionus calyciflorus collected from China were cultured at 18 degrees C, 23 degrees C, and 28 degrees C with 3.0 x 10(6) cells/mL of alga Scenedesmus obliquus to investigate their asexual and sexual reproduction. There were significant effects of both temperature and geographic population, independently and in interaction on population growth rate, fertilization rate of mictic females, and resting egg production of the rotifers. Geographic population and interaction between temperature and geographic population influenced significantly mixis rate in the rotifer population.
