Following environmental perturbation, benthic cyanobacteria can become an important component of primary producers replacing chlorophytes, epiphytes and macrophytes. In some sectors of the St Lawrence fluvial lakes, the proliferation of the benthic cyanobacterium Lyngbya wollei was detected. To test the interaction between cyanobacteria and gastropods, substratum choice experiments and growth experiments were performed on different gastropod species exposed to L. wollei, chlorophytes and submerged vascular macrophytes.
