This study analyzed water quality data from nearly 2,500 lakes across 17 states in the northeastern and midwestern regions of the United States in order to evaluate the effects of nitrogen stress on freshwater phytoplankton (as a metric of chlorophyll a). The results indicate the presence of synergistic influences of land use, climate, hydrology, and geography on the nitrogen stress of lake phytoplankton populations.
