We examined macrophyte–environment relationships in shallow lakes located within the Prairie Parkland and Laurentian Mixed Forest provinces of Minnesota. Environmental variables included land cover within lake watersheds, and within-lake, water and sediment characteristics. CCA indicated that sediment fraction smaller than 63μm (f<63), open water area, turbidity, and percent woodland and agricultural...
Macrophyte community structure in Lake Christina, a large shallow lake in west-central Minnesota, changed in response to a biomanipulation treatment in 1987. Three years of pre-treatment and 11 years of post-treatment data were analyzed. Using a combination of cluster analysis and indicator species analysis, three distinct macrophyte communities were identified: a pre-treatment community of low plant...
