Light-modulated responses of growth and photosynthetic performance to ocean a...
Ocean acidification (OA) due to atmospheric CO2 rise is expected to influence marine primary productivity. In order to investigate the interactive effects of OA and light... -
Iron limitation modulates ocean acidification effects on southern ocean phyto...
The potential interactive effects of iron (Fe) limitation and Ocean Acidification in the Southern Ocean (SO) are largely unknown. Here we present results of a long-term... -
Photophysiological responses of Southern Ocean phytoplankton to changes in CO...
The present study examines how different pCO2 acclimations affect the CO2- and light-dependence of photophysiological processes and O2 fluxes in four Southern Ocean (SO) key... -
CO2-driven seawater acidification increases photochemical stress in a green alga
Increased CO2 and associated acidification in seawater, known as ocean acidification, decreases calcification of most marine calcifying organisms. However, there is little... -
Seawater carbonate chemistry and photosynthesis of a coccolithophorid in a la...
Mixing of seawater subjects phytoplankton to fluctuations in photosynthetically active radiation (400-700 nm) and ultraviolet radiation (UVR; 280-400 nm). These irradiance... -
Experiment: Physiological responses of the calcifying rhodophyte, Corallina o...
Future atmospheric CO2 levels will most likely have complex consequences for marine organisms, particulary photosynthetic calcifying organisms. Corallina officinalis L. is an... -
Physiological responses of the marine diatom Thalassiosira pseudonana to incr...
We studied the effects of elevated CO2 concentration and seawater acidity on inorganic carbon acquisition, photoinhibition and photoprotection as well as growth and respiration... -
Ocean acidification mediates photosynthetic response to UV radiation and temp...
Increasing atmospheric CO2 concentration is responsible for progressive ocean acidification, ocean warming as well as decreased thickness of upper mixing layer (UML), thus... -
Rising CO2 and increased light exposure synergistically reduce marine primary...
Carbon dioxide and light are two major prerequisites of photosynthesis. Rising CO2 levels in oceanic surface waters in combination with ample light supply are therefore often... -
Reduced calcification decreases photoprotective capability in the Coccolithop...
Intracellular calcification of coccolithophores generates CO2 and consumes additional energy for acquisition of calcium and bicarbonate ions; therefore, it may correlate with... -
Future CO2-induced ocean acidification mediates the physiological performance...
The oceans take up more than 1 million tons of CO2 from the air per hour, about one-quarter of the anthropogenically released amount, leading to disrupted seawater chemistry due... -
(Table 1) Effects of desiccation on photochemical processes and nitrogenase a...
The effects of desiccation on photochemical processes and nitrogenase activity were evaluated in Nostoc commune s.l. colonies in situ from a wet thufur meadow at Petuniabukta,...
