| Abstract | This paper investigates the effects of atrazine and grass carp on freshwater macrophyte communities. Macrophyte communities in experimental ponds were subjected . to atrazine, at various concentrations, and grass carp and were sampled. periodically by a variation of the technique of grapnel analysis. Atrazine had significant effects upon the macrophyte community, causing changes in species composition leading to domination by Charophytes at levels of 100 μg/1. Grass carp displayed a greatly enhanced plant control capability when even low levels of atrazine were present. Field studies confirmed the hypothesis that general agricultural runoff is detrimental to macrophyte communities. Periphyton and emergent macrophytes also appeared to be adversely affected by atrazine. Results of this study suggest that atrazine in agricultural runoff can adversely impact on aquatic systems by altering, or eliminating, the habitat structure and diversity provided by macrophyte beds. Atrazine, and grass carp with atrazine, also appear to be useful tools in the management of macrophyte populations in lakes and ponds. |
