From: The organizing effects of elevated CO2 on competition among estuarine primary producers
δ13C content of Gracilaria and Ulva 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 three-way ANOVA, CO2 was a main treatment effect, on average (see Supplementary Table S2).
