Abstract: Submerged aquatic macrophytes are important in shallow aquatic ecosystems because they stabilize the macrophyte-dominated state by increasing water transparency in various ways. One of these is the excretion of allelopathic substances inhibitory to phytoplankton, but it is still controversial whether this mechanism can be important in the field. We developed a model that describes phytoplankton growth including the effects of two different macrophytes (Chara sp. and Stratiotes aloides), which are both known to excrete allelopathic substances. With this model we analysed singular and combined effects of shading (1), sediment resuspension (2), competition for nutrients (3) and allelopathy (4) on the development of phytoplankton.
