Agricultural, urban and industrial activities have dramatically increased aquatic nitrogen and
phosphorus pollution (eutrophication), threatening water quality and biotic integrity from …

Nitrogen (N) is used in many of life's fundamental biomolecules, and it is also a participant in
environmental redox chemistry. Biogeochemical processes control the amount and form of N …

Climate projections suggest–with substantial certainty–that global warming> 1.5° C will
occur by mid-century (2050). Population is also projected to increase, amplifying the …

Eutrophication is a complex process and often associated with not only a change in overall
algal biomass but also with a change in biodiversity. Common metrics of eutrophication (eg …

Preventing harmful algal blooms (HABs) is needed to protect lakes and downstream
ecosystems. Traditionally, reducing phosphorus (P) inputs was the prescribed solution for …

The nitrogen (N) cycle is one of the most important nutrient cycles in river systems, and it
plays an important role in maintaining biogeochemical balance and global climate stability …

Eutrophication in coastal waters caused by excess nutrient inputs has occurred widely on a
global scale. Due to the rapid economic development over the last four decades, most of the …

Historically, phosphorus (P) has been considered the primary limiting nutrient for
phytoplankton assemblages in freshwater ecosystems. This review, supported by new …

Ammonium sensitivity of plants is a worldwide problem, constraining crop production.
Prolonged application of ammonium as the sole nitrogen source may result in physiological …

It is now well recognized that there are more harmful algal blooms (HABs), more often, in
new and different places, often lasting longer, and with a range of toxicities, and that many of …
