2831 Pistia stratiotes Competition Experimental Laboratory Pistia stratiotes produces a-asarone, a phenylpropanoid with antialgal properties. The growth of all the algae species examined was severely inhibited by this compound. The marked antialgal activity of a-asarone confirms that the phenylpropanoids may interfere with growth processes in plants 29731
2832 Pistia stratiotes Competition Observational Field Dense mats of P. stratiotes can shade out and reduce the amount of light available to submerged macrophytes and planktonic algae 29732
2835 Pistia stratiotes Competition Observational Field Three years after P. stratiotes was first observed in Slovenia, a decline in the native freshwater plants Ceratophyllum demersum, Myriophyllum spicatum, Najas marina, and Trapa natans was observed. This was primarily due to the dense mat of P. stratiotes that covered the entire water surface year-round, even during the winter. 29781
2849 Pistia stratiotes Competition Experimental Laboratory Pistia stratiotes proved to be strongly competitive, improving growth at the expense of the other competitor species, Lemna minor and Salvinia minima. 33792
2851 Pistia stratiotes Competition Experimental Laboratory Competition trials showed that Pistia was very aggressive towards Limnobium causing yield to be greatly reduced in mixed treatments compared to single-species treatments. 33793
7124 Pistia stratiotes Competition Observational Field Oxygen and light limitations caused by Pistia stratiotes killed native plants, fish and wildlife. Florida 31302
7125 Pistia stratiotes Competition Anecdotal N/A Oxygen and light limitations caused by P. stratiotes killed native plants, fish and wildlife. 42134
7256 Pistia stratiotes Competition Observational Field Water lettuce (Pistia stratiotes) invasion in a oxbow lake on the Sava River, Slovenia outcompeted and reduced macrophyte species abundance. Remaining species were significantly reduced as well. Sava River, Slovenia 41788
7277 Pistia stratiotes Competition Experimental Laboratory Invasive water lettuce (Pistia stratiotes) has inhibitory effects on the growth of epiphtytic algae because its secrets alleochemicals and its biomass blocks sunlight. China 41822
9590 Pistia stratiotes Competition Observational Field In some regions of China, Pistia stratiote have displaced native Ottelia sp. and Nuphar sp.. China 43180
