Abstract

An attempt has been made to examine the extent to which seasonal periodicity of lacustrine phytoplankton corresponds to the general concepts of the theory of ecological succession. The study was carried out on an eutrophic lake (Aydat, France). As REYNOLDS (1980, 1984) suggests, the seasonal periodicity of phytoplankton is an autogenic succession which may be perturbed by allogenic physical processes that change the initial direction of the succession. Thus, in this lake, only spring succession of phytoplankton can be considered as a true succession, consistent with the theory of ecological succession in that it was a directional and predictable phenomenon leading to an increasing complexity of community.

Seasonal succession of phytoplankton was studied in a eutrophic lake (Lake Aydat, Massif Central, France), from March to November 1985.

## Abstract Annual data sets, from 1980–81 and 1994–95, provide evidence that inter‐annual differences in the seasonal succession of phytoplankton in the Swan River Estuary can be attributed to rainfall and salt‐wedge movement. The distribution and succession of phytoplankton are influenced by seas
