Two Southern Ocean diatoms are more sensitive to ocean acidification and chan...
To better understand the impact of ocean acidification (OA) and changes in light availability on Southern Ocean phytoplankton physiology, we investigated the effects of pCO2... -
Physiological responses of coastal and oceanic diatoms to diurnal fluctuation...
Diel and seasonal fluctuations in seawater carbonate chemistry are common in coastal waters, while in the open-ocean carbonate chemistry is much less variable. In both of these... -
Decreased photosynthesis and growth with reduced respiration in the model dia...
Studies on the long-term responses of marine phytoplankton to ongoing ocean acidification (OA) are appearing rapidly in the literature. However, only a few of these have... -
Interactive effects of light, nitrogen source, and carbon dioxide on energy m...
Due to the ongoing effects of climate change, phytoplankton are likely to experience enhanced irradiance, more reduced nitrogen, and increased water acidity in the future ocean.... -
Nitrate limitation and ocean acidification interact with UV-B to reduce photo...
It has been proposed that ocean acidification (OA) will interact with other environmental factors to influence the overall impact of global change on biological systems.... -
Macroalgal responses to ocean acidification depend on nutrient and light levels
Ocean acidification may benefit algae that are able to capitalize on increased carbon availability for photosynthesis, but it is expected to have adverse effects on calcified... -
Ocean acidification decreases the light-use efficiency in an Antarctic diatom...
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2015) was used to compute a complete and consistent set of... -
Photochemical responses of the diatom Skeletonema costatum grown under elevat...
Variability in pH is a common occurrence in many aquatic environments, due to physical, chemical and biological processes. In coastal waters, lagoons, estuaries and inland... -
Solar UV irradiances modulate effects of ocean acidification on the Coccolith...
Emiliania huxleyi, the most abundant coccolithophorid in the oceans, is naturally exposed to solar UV radiation (UVR, 280-400 nm) in addition to photosynthetically active... -
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... -
Seawater carbonate chemistry and the photophysiology of Thalassiosira pseudon...
Increasing anthropogenic carbon dioxide is causing changes to ocean chemistry, which will continue in a predictable manner. Dissolution of additional atmospheric carbon dioxide... -
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...
