Abstract |
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 abundance, an early post-treatment community dominated by Najas flexilis, N. marina, Myriophyllum sibiricum and Ruppia maritime, and a late post-treatment community characterized by Chara vulgaris, C. canescens, Potamogeton pectinatus, and P. pusillus. Canonical correspondence analysis (CCA) showed that these changes in plant community structure are associated with improvements in water clarity and annual variation in abundance of filamentous algae. |
