INTRODUCTION
Colonial cyanobacteria can suppress the growth, survivorship, and fecundity of freshwater zooplankton in various ways. They may have endotoxins, which poison susceptible taxa that ingest them, they may excrete toxins or inhibitors, which affect taxa that may or may not ingest them, they generally are of poor nutritional quality to taxa that eat them, and they may mechanically interfere with feeding. Accordingly, these cyano-bacteria may have important effects on zooplankton population dynamics and species structure. Such effects on the zooplankton may then secondarily influence organisms at lower and higher trophic levels. Much older literature on ...
