AB Three macroalgal species belonging to Chlorophyta (Ulva rigida), Rhodophyta(Ellisolandia elongata) and Phaeophyceae (Heterokontophyta; Cystoseira tamariscifolia), naturally growing at the same shore level and representing 3 morpho-functional groups, were exposedto short-term changes in temperature under different carbon and nitrogen regimes. Experimentswere conducted in outdoor tanks at 4 combinations of carbon and nitrogen levels under reducedsolar radiation. In vivo chl a fluorescence parameters and pigment contents were monitored toassess diurnal physiological responses and potential for recovery. Strong fluctuations in chl a fluorescence parameters, but not in chl a content, were observed in response to diurnal variation insolar radiation and light climate within the tanks; sensitivity varied between algal species and, insome cases, depended on the carbon and nitrogen regime. Nitrogen uptake was similarly high inU. rigida and E. elongata and lowest in C. tamariscifolia. In U. rigida and E. elongata, chl a concentrations decreased after high-carbon treatments. Effective photosystem II quantum efficiencywas reduced in all species at noon, and lowest in C. tamariscifolia. The results highlight the complexity of physiological short-term acclimations which were most likely linked to biochemicalchanges at the cellular level. Long-term experiments are required in future for more comprehensive investigation of the observed interactive effects of the different environmental parameters.
