The presence of Eurasian watermilfoil ( Myriophyllum spicatum L.) in aquatic systems has resulted in adverse impacts to native plant communities, ecosystem function, and water resource uses. Eurasian watermilfoil in Hayden Lake, Idaho, has spread rapidly, impacting the native plant community and recreational uses of the lake. Point intercept surveys were conducted to determine the current compo...

Cadmium (Cd) is highly toxic and widely distributed in aquatic systems due to its high solubility mobility water, which can severely inhibit the survival of macrophytes. The phytotoxicity Cd depends on environmental factors; however, it remains unclear whether how light quality affects toxicity In this study, we investigated effects macrophytes Potamogeton crispus under different qualities (whi...

The epiphytic algae were studied on three aquatic plants (Ceratophyllum demersum, Myriophyllum verticillatum and Potamogeton pectinatus) from seven stations in Euphrates River between Hindia barrage Al-Kufa city-Iraq, during summer 2004 spring 2005. A total of (97) species identified, diatoms dominant their number (73% the number), followed by chlorophyta, then cyanophyta Euglenophyta. Variatio...
