Too many nutrients make microbes less responsive

Bacteria in lakes play a key role in maintaining water quality by absorbing excess nitrogen and phosphorus. They also help store carbon, which has implications for our climate. But, as it turns out, their ability to do these ...

Projected precipitation increases are bad news for water quality

If climate change is not curbed, increased precipitation could substantially overload U.S. waterways with excess nitrogen, according to a new study from Carnegie's Eva Sinha and Anna Michalak and Princeton University's Venkatramani ...

Fixing the role of nitrogen in coral bleaching

Excess nitrogen is shown to disrupt coral-algae symbiosis, triggering bleaching even in the absence of heat and light stress. With coral bleaching events intensifying as global sea temperatures rise, this is an important ...

Chesapeake Bay pollution extends to early 19th century

Humans began measurably and negatively impacting water quality in the Chesapeake Bay in the first half of the 19th century, according to a study of eastern oysters by researchers at The University of Alabama.

Researcher unveils tool for a cleaner long island sound

A new model released today at the meeting of the American Association for the Advancement of Science by UConn ecologist Jamie Vaudrey pinpoints sources of nitrogen pollution along Long Island Sound, and shows municipalities ...

Arctic found to play unexpectedly large role in removing nitrogen

Areas of the Arctic play a larger role than previously thought in the global nitrogen cycle—the process responsible for keeping a critical element necessary for life flowing between the atmosphere, the land and oceans. ...
