Two grass species that had been relatively rare in the plots, Spartina patens and Distichlis spicata, began to respond vigorously to the excess nitrogen. Eventually the grasses became much more abundant. Nitrogen ultimately changed the composition of the ecosystem as well as its capacity to store carbon.

The Encyclopedia of Life is an unprecedented global effort to document all 1.8 million named species of animals, plants and other forms of life on Earth. For the first time in the history of the planet, scientists, students, and citizens will have multi-media access to all known living species, even those that have just been discovered. The Field Museum of Natural History, Harvard University, Marine Biological Laboratory, Smithsonian Institution, and Biodiversity Heritage Library joined together to initiate the project, bringing together species and software experts from across the world.
