Seawater carbonate chemistry and swimming behaviors of the raphidophyte Heter...
We investigated the effects of pH on movement behaviors of the harmful algal bloom causing raphidophyte Heterosigma akashiwo. Motility parameters from >8000 swimming tracks... -
Experiment: Dissecting the impact of CO2 and pH on the mechanisms of photosyn...
Coccolithophores are important calcifying phytoplankton predicted to be impacted by changes in ocean carbonate chemistry caused by the absorption of anthropogenic CO2. However,... -
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... -
Ocean acidification slows nitrogen fixation and growth in the dominant diazot...
Dissolution of anthropogenic CO(2) increases the partial pressure of CO(2) (pCO(2)) and decreases the pH of seawater. The rate of Fe uptake by the dominant N(2)-fixing... -
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... -
The morphological response of Emiliania huxleyi to seawater carbonate chemist...
Four strains of the coccolithophore Emiliania huxleyi (RCC1212, RCC1216, RCC1238, RCC1256) were grown in dilute batch culture at four CO2 levels ranging from ~200 µatm to ~1200... -
Seawater carbonate chemistry and growth, calcification of Thoracosphaera heim...
Ocean acidification is considered a major threat to marine ecosystems and may particularly affect calcifying organisms such as corals, foraminifera and coccolithophores. Here we... -
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 growth, carbon acquisition, and species inte...
Despite the fact that ocean acidification is considered to be especially pronounced in the Southern Ocean, little is known about CO2-dependent physiological processes and the... -
Seawater carbonate chemistry and survival, impairment of three phytoplankton ...
Sodium hypochlorite (NaOCl) is widely used to disinfect seawater in power plant cooling systems in order to reduce biofouling, and in ballast water treatment systems to prevent... -
Seawater carbonate chemistry and net photosynthesis, C/N ratio, growth rate, ...
Phytoplankton are the basis of marine food webs, and affect biogeochemical cycles. As CO2 levels increase, shifts in the frequencies and physiology of ecotypes within... -
Seawater carbonate chemistry and maximum growth rates of Skeletonema marinoi ...
Phytoplankton populations can display high levels of genetic diversity that, when reflected by phenotypic variability, may stabilize a species response to environmental changes.... -
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,... -
Interactive effects of ocean acidification and nitrogen limitation on the dia...
Climate change is expected to bring about alterations in the marine physical and chemical environment that will induce changes in the concentration of dissolved CO2 and in... -
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... -
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... -
Phytoplankton measurements from the Namibian upwelling system during the Mari...
Phytoplankton samples taken by CTD- rosette sampler from different depths within the upper mixed layer. Date are mean values of the depth range given. Phytoplankton counted by... -
Seawater carbonate chemistry, nutrients, and Calcidiscus leptoporus (strain R...
The coccolithophore Calcidiscus leptoporus was grown in batch culture under nitrogen (N) as well as phosphorus (P) limitation. Growth rate, particulate inorganic carbon (PIC),... -
