Results of the two-way ANOVA of the interaction of UVR and P-enrichment.

Interactive effect on respiration, reactive oxygen species, total and dissolved alkaline phosphatase and dissolved organic carbon (Table A). Interactive effect on C, P and N cell-quota, particulate organic carbon, particulate organic nitrogen, particulate organic phosphorus, C:P, C:N and N:P ratios (Table B). Interactive effect on maximal electron transport rate, photosynthetic efficiency, Dd de-epoxidation; microphytoplanktonic and, picophytoplanktonic carbon incorporation, percentage excreted organic carbon, productivity and total abundance (Table C). F values and significance levels (p) are shown, numbers in bold indicate, p-value T:t otal alkaline phosphatase activity;APAEX: dissolved alkaline phosphatase activity; DOC: dissolved organic carbon. POC: particulate organic carbon; PON: particulate organic nitrogen; POP: particulate organic phosphorus ETRmax: maximal electron transport rate; αETR: photosynthetic efficiency; Dt:Dt+Dd: Dd de-epoxidation; PPM: microphytoplanktonic carbon incorporation; PPP: picophytoplanktonic carbon incorporation;%EOC: Percentage excreted organic carbon.
