“…ΔF/F' m decreased drastically after 1.5 h of exposure to high irradiance and temperature, particularly in LNS algae. Nutrient limitation has been associated with increased vulnerability to photoinhibition by PAR and UVR in microalgae (Litchman et al 2002, Shelly et al 2002, van de Poll et al 2005) and macroalgae (Döhler et al 1995, Korbee Peinado et al 2004, Korbee et al 2005. The decrease in ΔF/F' m was similar in all light treatments, i.e.…”

Effects of nutrient supply on photosynthesis and pigmentation in Ulva lactuca (Chlorophyta): responses to short-term stress

The effects of nutrient supply on photosynthesis (estimated as chlorophyll fluorescence), chlorophyll content, biomass yield and proximate chemical composition of tank cultivated Ulva lactuca L. (Chlorophyta) were evaluated. To assess the effect of nutrient supply on resistance capacity against short-term stress, algae grown in high nutrient supply (HNS) fishpond effluents and in low nutrient supply (LNS) oligotrophic seawater were transferred to small vessels with increased irradiance of PAR and UV radiation (PAR+UVA and PAR+UVA+UVB using cut-off filters) and increased temperature as compared to culture tanks. Electron transport rate and chlorophyll content were higher in HNS than in LNS algae. Effective quantum yield and chlorophyll content decreased after short-term exposure to high PAR irradiance. Full recovery of photosynthesis in the shade was observed under a moderately higher temperature (Δ+ 6°C). UVB exposure reduced the negative effect of UVA on photosynthesis and pigment accumulation under temperature stress (Δ+10°C), particularly in HNS algae. Growth under HNS appeared to accelerate acclimation of Ulva lactuca to short-term environmental changes, such as higher temperatures (as in heat waves) and higher UV radiation. Furthermore, nitrogen enrichment reduced the common inhibitory effects of short-term stress such as increased irradiance, UV radiation and temperature on photosynthesis.

“…Similar results were found for other Porphyra species, Grateloupia lanceola and Gracilaria spp. (Korbee et al 2005a, Huovinen et al 2006, Barufi et al 2011). In our study, the MAA total content decreased in algae transplanted from 100% PAB to 70% PAB and after nutrient enrichment, whereas no effect of nutrient was observed in algae collected from 2.0 m depth waters.…”

Short-term ecophysiological and biochemical responses of Cystoseira tamariscifolia and Ellisolandia elongata to changes in solar irradiance and nutrient levels were analyzed in situ in oligotrophic coastal waters by transferring macroalgae collected at 0.5 and 2.0 m depth and exposing them to 2 irradiance levels (100 and 70% of surface irradiance) and nutrient conditions (nutrient-enriched and non-enriched). Both species were affected by changes in irradiance and nutrient levels. Few interactive effects between these 2 physical stressors were found, suggesting major additive effects on both species. C. tamariscifolia collected at 0.5 m and exposed to 70% irradiance had the highest maximal electron transport rate (ETR max ), saturated irradiance (Ek ETR ) and chl a content and the lowest antioxidant activity. Under the same conditions, E. elongata had increased Ek ETR , antheraxanthin and β-carotene content. At 100% irradiance, C. tamariscifolia collected at 2.0 m had higher maximal quantum yield (F v /F m ), photosynthetic efficiency (α ETR ), ETR max , maximal non-photochemical quenching (NPQ max ), saturation irradiance for NPQ (Ek NPQ ), and antheraxanthin and polyphenol content increased, whereas in E. elongata only α ETR increased. In nutrient-enriched conditions, phenolic compounds, several carotenoids and N content increased in C. tamariscifolia at both depths. E. elongata from 2.0 m depth at 100% irradiance and nutrient-enriched conditions showed increased N content and total mycosporine-like amino acids (MAAs). Our results show rapid photophysiological responses of C. tamariscifolia to variations in in situ irradiance and nutrient conditions, suggesting efficient photoacclimation to environmental changes. In E. elongata, F v /F m and ETR max did not change in the transplant experiment; in contrast, N content, pigment and MAAs (biochemical variables) changed. The responses of these macroalgae to nutrient enrichment indicate oligotrophic conditions at the study site and environmental stress.

“…This can be advantageous under stressful conditions, since asterina-330 presented a high antioxidant activity against hydrosoluble radicals (ABTS assay) and lipid peroxidation (β-carotene oxidation assay) (De la Coba et al 2009). N enrichment increases the accumulation of MAAs in different species of red macroalgae of the genus Porphyra (Pyropia) (Korbee-Peinado et al 2004, Korbee et al 2005, Gracilaria (Zheng & Gao 2009, Figueroa et al 2010 and Grateloupia (Huovinen et al 2006). In spite of the fact that MAAs are N-containing compounds, no significant effect of N as a single factor was found for the accumulation of MAAs, except for the double interaction of N × time for all MAAs except palythinol, and the double interaction N × temperature for all MAAs except shinorine.…”
