Seasonal succession of phytoplankton was studied in a eutrophic lake (Lake Aydat, Massif Central, France), from March to November 1985. An attempt is made to check the succession stages of the concept of ecological succession theory using either the H‐diversity index of S HANNON and W EAVER or the F RONTIER'S rank‐frequencies diagrams. A description of a stage 3 community was only possible through the use of the latter diagrams.
