Macroalgal responses to ocean acidification depend on nutrient and light levels
TLDR
Investigating the physiological responses of macroalgae near a CO2 seep in oligotrophic waters off Vulcano (Italy) showed that elevated CO2 levels benefitted both of these algae, although their responses varied depending on light and nutrient availability. Expand
Effects of nutrient supply on photosynthesis and pigmentation in Ulva lactuca (Chlorophyta): responses to short-term stress
TLDR
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, and nitrogen enrichment reduced the common inhibitory effects of short- term stress such as increased irradiance, UV radiation and temperature on photosynthesis. Expand
Effects of short-term irradiation on photoinhibition and accumulation of mycosporine-like amino acids in sun and shade species of the red algal genus Porphyra.
TLDR
The sun type algae presented a higher capacity of acclimation to increased irradiance than the shade type algae, explained by the higher thermal dissipation and by the accumulation of MAAs. Expand
Effects of N supply on the accumulation of photosynthetic pigments and photoprotectors in Gracilaria tenuistipitata (Rhodophyta) cultured under UV radiation
TLDR
A high potential to acclimation and photoprotection against stress factors (including high PAR and UVR) directly related to N availability for G. tenuistipitata is suggested. Expand
Short-term effects of increasing CO2, nitrate and temperature on three Mediterranean macroalgae: biochemical composition
TLDR
The functional patterns of the 3 macroalgae in response to the pCO2, nitrogen and temperature regimes may be explained in terms of their bio-optical characteristics and antioxidant activity. Expand
Effect of nutrient supply on photosynthesis and pigmentation to short-term stress (UV radiation) in Gracilaria conferta (Rhodophyta).
TLDR
Results support that nutrient-sufficiency help G. conferta to resist environmental changes as short-term temperature increase and support the idea that photosynthetic activity, pigment content, C:N ratio and biomass yield are affected by environmental changes. Expand
The influence of environmental features in the content of mycosporine‐like amino acids in red marine algae along the Brazilian coast
TLDR
Enhanced MAA contents, for example, were found in environments with a basic pH, a high ultraviolet index, and high concentrations of phosphate and nitrate, which confirmed that some environmental factors influenced the content of MAAs. Expand
Short-term ecophysiological and biochemical responses of Cystoseira tamariscifolia and Ellisolandia elongata to environmental changes
TLDR
The results show rapid photophysiological responses of C. tamariscifolia to varia- tions in in situ irradiance and nutrient conditions, suggesting efficient photoacclimation to envi- ronmental changes. Expand
Physiological response and photoacclimation capacity of Caulerpa prolifera (Forsskål) J.V. Lamouroux and Cymodocea nodosa (Ucria) Ascherson meadows in the Mar Menor lagoon (SE Spain).
TLDR
The results suggest that C. prolifera behaves as a shade-adapted species with a low photoprotective capacity, light being one of the main factors governing its distribution in the lagoon and the high photosynthetic capacity and lack of photoinhibition found in C. nodosa suggest that this species is highly photop rotated. Expand
Photoprotection mechanisms against ultraviolet radiation in Heterocapsa sp. (Dinophyceae) are influenced by nitrogen availability: Mycosporine‐like amino acids vs. xanthophyll cycle
TLDR
It is concluded that not only MAA accumulation but also N availability is very important to determine the photoprotective capacity against UVR of Heterocapsa sp. Expand
