Sensitive response of sediment-grown Myriophyllum

2016-8-30  Aquatic plants may face resource constraints or anthropogenic pollution, and effects might be heightened under multiple stress conditions. We investigated if arsenate effects on Myriophyllum spicatum L. would be stronger under CO2 limitation and low phosphorus availability. In a factorial design, we exposed sediment-grown plants to either CO2 (high carbon or HC) or
