Isoetid species are small, slow-growing, evergreen water plants with thick, stiff leaves or
stems that form basal rosettes and have a proportionally large below ground biomass …

This paper presents a review of the trends and geographic variation of impacts of reactive
nitrogen (N) inputs on in Europe through impacts on air, soil and water quality. It illustrates …

Increased ammonium concentrations and decreased light availability in a water column
have been reported to adversely affect submersed vegetation in eutrophic waters worldwide …

Experimental and field studies were conducted to evaluate the effects of NH4+ enrichment
on growth and distribution of the submersed macrophyte, Vallisneria natans L, in lakes of the …

We tested the relationship between Sphagnum growth and the amount of nitrogen stored in
free amino acids in a fertilisation experiment with intact peat monoliths in an open …

Submersed macrophytes in eutrophic lakes often experience high NH4+ concentration and
low light availability in the water column. This study found that an NH4+–N concentration of …

In sheltered, eutrophicated estuaries, reduced nitrogen (NH x), and pH levels in the water
layer can be greatly enhanced. In laboratory experiments, we studied the interactive effects …

The heavy bloom of cyanobacteria is a disastrous consequence of freshwater
eutrophication, and the bloom is highly toxic due to its secondary metabolites called …

In the last century, Stratiotes aloides L.(Water Soldier) has declined considerably in the
Netherlands. The species has disappeared almost completely from the littoral zones of the …

The Netherlands is “well known” for its nitrogen problems; it has one of the highest reactive
nitrogen (Nr) emission densities in the world. It is a small country at the delta of several large …
