Daphnia pulex, a common cladoceran zooplankton species, contains tissue cAMP concentrations similar to those found in algae, bacteria, and aquatic macrophytes. Daphnia release significant quantities of cAMP into the extracellular medium. Release of algal cellular cAMP as a result of digestive degradation of algal cells may also be an important source of dissolved cAMP in lakewater.
