Photochemical and photophysical properties of carotenoid immobilized on a surfactant micellar medium including chlorophyll as an artificial photosynthesis system
Artificial photosynthesis Carotenoid Crocetin Light-harvesting Mg chlorophyll-a, b Photo-protection
2010/12/2
To develop an artificial photosynthesis model, the anionic water-soluble carotenoid dye crocetin was electrostatically immobilized onto the surface of cationic surfactant cetyltrimethylammonium bromid...
Gross photosynthesis and lake community metabolism during the spring phytoplankton bloom
Gross photosynthesis lake community metabolism spring phytoplankton bloom
2014/5/5
Daily productivity determinations of linear photosynthetic electron transfer and of net and gross inorganic CO2 uptake were determined in situ throughout a 6-week sampling period of the spring phytopl...
We compared 190 photosynthesis–irradiance (P-E) experiments with single- and multispecies communities of
macroalgae and vascular plants from freshwater and marine habitats. We found a typical hyperbo...
Photosynthesis and light utilization in the Caribbean coral Montastraea faveolata recovering from a bleaching event
Photosynthesis light utilization
2014/5/5
Coral bleaching—the loss of symbiotic dinoflagellates—is initiated when corals are exposed to sea surface
temperatures above the regional summer average and has been responsible for massive coral mor...
The effect of carbonate chemistry on calcification and photosynthesis in the hermatypic coral Acropora eurystoma
The effect of carbonate chemistry calcification and photosynthesis hermatypic coral Acropora eurystoma
2014/5/4
The rise in atmospheric CO2 has caused significant decrease in sea surface pH and carbonate ion (CO3-2) concentration. This decrease has a negative effect on calcification in hermatypic corals and oth...
Effect of short-term exposure to elevated temperatures and light levels on photosynthesis of different host-symbiont combinations in the Aiptasia pallida / Symbiodinium symbiosis
Effect of short-term exposure elevated temperatures light levels photosynthesis of different host-symbiont combinations Aiptasia pallida Symbiodinium symbiosis
2014/5/13
The physiology exhibited by symbioses between dinoflagellates (zooxanthellae) and hosts such as reef corals may be dictated by the host, the symbiont, or the synergistic effect of both partners. We co...
Photosynthesis-controlled calcification in a hypersaline microbial mat
Photosynthesis-controlled calcifi cation hypersaline microbial mat
2014/5/13
We investigated the hypothesis that sulfate reduction rather than oxygenic photosynthesis promotes calcification
in a hypersaline microbial mat by increasing the ion concentration product: ICP ...
Patterns in microphytobenthic primary productivity: Species-specific variation in migratory rhythms and photosynthesis in mixed-species biofilms
microphytobenthos primary productivity Species-specific variation migratory rhythms photosynthesis mixed-species biofilms

The importance of temporal changes in the vertical distribution of microphytobenthic algae on the overall functioning of intertidal biofilms were investigated with low-temperature scanning electron mi...
A biooptical model of irradiance distribution and photosynthesis in seagrass canopies
A biooptical model irradiance distribution and photosynthesis seagrass canopies
2014/5/19
Although extremely vulnerable to coastal eutrophication, seagrasses represent important structuring elements and sources of primary production in shallow waters. They also generate an optical signatur...
Influence of the Inorganic Carbon Addition on Photosynthesis of Algae and Some Macrophytes
KHCO3- uptake algal photosynthesis pH alkalinity oxygen production fish-pond
2010/3/22
A two-step experiment was conducted in order to understand whether natural algal communities (fish-pond water) and selected macrophytes (Potamogeton pectinatus L. Elodea nuttallii (Planch.). St.John. ...

inorganic carbon photosynthesis a strain of Phaeodactylum tricornutum
2014/5/27
Diatoms are an important functional group of marine phytoplankton because of their role in the fixation of atmospheric carbon dioxide (CO2) and transfer of organic carbon to deep waters. Carbon-concen...
Benthic photosynthesis in an acidic mining lake (pH 2.6)
Benthic photosynthesis acidic mining lake
2014/5/27
Natural neutralization of acidic mining lakes is usually limited by the availability of organic carbon. We investigated whether benthic photosynthesis could contribute to primary production in an acid...
