From the Backyard to the Ocean: New Study Shows Streams Act as Key Nitrogen Filters
March 12, 2008
As spring arrives, tourists at beaches will face the reality of "red tide"--harmful algae blooms that pose risks to humans and sea life. What they may not realize, though, is that small streams running through their neighborhoods filter the nitrogen that feeds the blooms. A new study, published in the journal Nature, sheds new light on the streams' role and shows that nitrogen increases caused by humans, make it harder for streams to do their jobs.
