Frequency distribution studies of epipelic diatoms along an intertidal shore

Abstract
Live and dead cell counts of epipelic diatoms were analysed at 16 sites along a transect crossing a saltmarsh, sandflat, and mudflat at Berrow Flats, Somerset, U.K. Replicate monthly samples were taken from January 1982 to June 1984. The ratio of dead to live cells varied according to position along the transect. Temporal changes of the ratios did not display a cyclic seasonal pattern. The clustered mosaic of live cells and empty frustules on surface sediments was quantitatively assessed. Graphing variance against seasonal mean cell counts showed that the variance was proportional to the square of the mean. The Neyman Type A equation is suggested as a possible model to explain this relationship.
