Abstract

The planktonic/littoral diatom ratios from a shallow prairie lake and a deep lake in the coniferous-deciduous forest region of Minnesota, U.S.A., were compared with the mean and maximum depths and the Secchi disc transparencies. The results indicate that the ratios of P/L and the mean and maximum depths and transparency, correspondingly, may be significantly higher for a shallow lake than for a deep lake.
