How Atmospheric Deposition of Nitrogen Alters Alpine Lake Chemistry
Quick fact
In many alpine lakes, the dominant algae are shifting: nitrogen-loving species like cyanobacteria and chlorophytes are replacing classic diatoms—a change driven by nitrogen falling from the sky, even in remote areas far from cities.
Why this is interesting
You may expect a pristine mountain lake to be the purest ecosystem on Earth. But what if the very rain that fills it carries a hidden fertilizer that is turning the water green?
