title: Nuclear number in the rotifer asplanchna: intraclonal variation and environmental control.
abstract: The gastric glands and vitellarium of Asplanchna are exceptions to the rule of constancy of the number of nuclei in rotifers. The two glands of a female may have different numbers of nuclei. Nuclear number in both organs varies widely among different individuals in a single culture. The mean nuclear number characteristic of a clone may be modified by dietary changes.
