The different responses of growth and photosynthesis to NH4+ enrichments between Gracilariopsis lemaneiforrnis and its epiphytic alga Ulva lactuca grown at elevated atmospheric CO2
We investigated how elevated CO2 affects the responses of Gracilariopsis lemaneiformis and Ulva lactuca to NH4+ enrichments. All algae were incubated under four nutritional conditions (zero addition, 100, 500, and 2500 mu M NH4+), and two CO2 levels (390 ppm and 1000 ppm). The growth, photosynthesis...
