The purpose of these studies was to examine the effects of various kinds and amounts of trace metals on the structure of algal communities and their possible subsequent effect upon the productivity of the aquatic ecosystem. To carry out this program of study, the following trace metals were examined: vanadium, chromium, selenium, boron, nickel, and rubidium. The results of these experiments indicate the concentration and form of a trace metal may have a definite effect upon which algal species can out-compete others. These shifts may greatly reduce the productivity of the system as a whole. If the shift is to species which has such lower predator pressure, large standing crops which may be nuisances may develop.
