We examine the photosynthetic response of submerged plants from streams and lakes with contrasting free-CO2 and nitrogen (N) availability. We hypothesized that: the photosynthetic capacity of stream plants is higher because of higher N availability; the photosynthetic N-use efficiency (PNUE) is also...
