The nitrogen costs of photosynthesis in a diatom under current and future pCO2
With each cellular generation, oxygenic photoautotrophs must accumulate abundant protein complexes that mediate light capture, photosynthetic electron transport and carbon... -
Decreased light availability can amplify negative impacts of ocean acidificat...
Coral reef organisms are increasingly and simultaneously affected by global and local stressors such as ocean acidification (OA) and reduced light availability. However,... -
Calcareous green alga Halimeda tolerates ocean acidification conditions at tr...
We investigated ecological, physiological, and skeletal characteristics of the calcifying green alga Halimeda grown at CO2 seeps (pHtotal ~ 7.8) and compared them to those at... -
Saturating light and not increased carbon dioxide under ocean acidification d...
Carbon physiology of a genetically identified Ulva rigida was investigated under different CO2(aq) and light levels. The study was designed to answer whether (1) light or... -
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... -
Effects of ultraviolet radiation and CO2 increase on winter phytoplankton ass...
Increases in ultraviolet radiation (UVR) and CO2 affect phytoplankton growth and mortality in a variety of different ways. However, in situ responses of natural phytoplankton... -
Ocean Acidification Affects Redox-Balance and Ion-Homeostasis in the Life-Cyc...
Ocean Acidification (OA) has been shown to affect photosynthesis and calcification in the coccolithophore Emiliania huxleyi, a cosmopolitan calcifier that significantly... -
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: Combined effects of CO2, temperature, irradiance and time on the ...
In natural environments, marine biotas are exposed to a variety of simultaneously acting abiotic factors. Among these, temperature, irradiance and CO2 availability are major... -
Effects of feeding and light intensity on the response of the coral Porites r...
Recently, it has been suggested that there are conditions under which some coral species appear to be resistant to the effects of ocean acidification. To test if such resistance... -
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... -
Light availability determines susceptibility of reef building corals to ocean...
Elevated seawater pCO2, and in turn ocean acidification (OA), is now widely acknowledged to reduce calcification and growth of reef building corals. As with other environmental... -
Seawater carbonate chemistry and photosystem II photoinactivation of the coas...
We studied the interactive effects of pCO2 and growth light on the coastal marine diatom Thalassiosira pseudonana CCMP 1335 growing under ambient and expected end-of-the-century... -
Seawater carbonate chemistry and concentration boundary layers around complex...
Metabolic processes have the potential to modulate the effects of ocean acidification (OA) in nearshore macroalgal beds. We investigated whether natural mixed assemblages of the... -
Seawater carbonate chemistry and growth rate of Emiliania huxleyi in lab expe...
Predicting the impacts of environmental change on marine organisms, food webs, and biogeochemical cycles presently relies almost exclusively on short-term physiological studies,... -
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... -
Growth and photosynthesis of a diatom Cylindrotheca closterium grown under el...
The combination of elevated CO2 and the increased acidity in surface oceans is likely to have an impact on photosynthesis via its effects on inorganic carbon speciation and on... -
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... -
