Ecological Factors and the Distribution of Cladophora glomerata in the Great Lakes

Nutrient enrichment in the Great Lakes has provided fertile areas for growth of algal nuisances. One of these species, Cla- dop,hora glomerata, has become a major problem for many cities border- ing the Great Lakes. Ecological factors concerning its growth in Milwau- kee's Harbor were studied, and its distribution in the Great Lakes deter- mined. Phosphorus levels appear to be closely linked with Cladophora increases.
