Productivity Paradox


This graphic shows the effects of long-term phosphorus enrichment in Everglades wetlands. FCE scientists have shown that exposure to phosphorus at any level above background initiates a cascade of changes, from a loss of natural periphyton communities, to replacement by more palatable non-mat forming algae, then to an open-water state that eventually leads to the spread of invasive cattails.
