Nitrogen is one of the most important elements in the ecology of all ecosystems, including those dominated by humans. So, developing a better understanding of how nitrogen moves into and out of ecosystems is essential. Where does nitrogen come from and where does it wind up? What story does it tell?
As an example of this environmental science effort, Boyton and his colleagues used a budget approach to track nitrogen through the Patuxent watershed, a large tributary of the Chesapeake. In a way, this is similar to developing a money-based budget for one’s home. This big ecosystem story had some surprising results.
