From: The organizing effects of elevated CO2 on competition among estuarine primary producers
Tissue nitrogen, carbon, and C:N content of Gracilaria exposed to ambient and elevated CO2 conditions, with and without competition from Ulva, and with and without competition from plankton for experiments performed July through October. For tissue N and C:N ratio, CO2, the presence of plankton (un/filtered), and the presence of Ulva were main treatment effects of three-way ANOVA, on average (see Supplementary Table S2).
