Includes bibliographical references. "Enclosure experiments and indeed whole lake investigations are complicated by the contribution of the community growing on the edge of the enclosure or in the littoral zone of lakes. It consists of algae, bacteria, and invertebrates (zooplankton, amphipods, chironomids and snails). In the following investigation, the relative importance of top-down(fish) vs bottom-up (nutrients) on the biomass and composition of the littoral community on large lake enclosures was determined. The influence of wall growth on the phosphoruscycling in the enclosure was shown to be no more important than the influence of the littoral zone on small temperate lakes"--Executive summary.
