Trophic factors, such as community structure and the amount of nannoplankton food available was of considerable influence to rotifer fertility, especially among sedimentators, while abiotic factors had a much smaller influence.

A Simplified Method for the Preparation of Rotifers for Transmission and Scanning Electron MicroscoTor TEM and SEM prepatations, rotifers are placed in little panels made of plastic Beem capsules normally used for embedding, with their conical parts cut off and closed by plankton filter cloth. Thus, the risk of losing animals is considerably reduced.
