Macrophytes as bioindicators
Kohler, Alexander; Schneider, Susanne
Submerged macrophytes respond to changes in the nutrient concentrations in their environment. In contrast to diatoms e.g., submerged macrophytes are capable of taking up nutrients from both the sediment pore water and the overlying water. Therefore, macrophytes can provide a more comprehensive assessment of river ecosystems. Two methods using submerged macrophytes to assess and monitor changes in the nutrient status of running waters are described.
