δ13C is a signature of light availability and photosynthesis in seagrass
δ13C signature of light availability photosynthesis in seagrass
2014/4/4
We explored the role of light-saturated (carbon-limited) photosynthesis on δ13C of turtlegrass (Thalassia testudinum Banks ex König) populations from the clear, blue waters of the Great Bahama Ba...
In situ diel cycles of photosynthesis and calcification in hermatypic corals
In situ diel cycles photosynthesis calcification hermatypic corals
2014/4/17
Diel cycles of photosynthesis, respiration, and calcification were studied in situ on two hermatypic corals,Acropora eurystomaandFavia favus, using a submerged respirometer deployed at 5-m depth in th...
Diffusive boundary layers do not limit the photosynthesis of the aquatic macrophyte Vallisneria americanaat moderate flows and saturating light levels
Diffusive boundary layers do not limit the photosynthesis the aquatic macrophyte Vallisneria americana moderate flows saturating light levels
2014/4/17
Hydrodynamic models of mass transport assume that diffusive processes next to the surface limit transport and that there are no biological and chemical processes that control the supply and demand of ...
CO2 control of Trichodesmium N2 fixation, photosynthesis, growth rates, and elemental ratios: Implications for past, present, and future ocean biogeochemistry
CO2 control Trichodesmium N2 fixation photosynthesis growth rates elemental ratios past present future ocean biogeochemistry
2014/4/22
Diazotrophic marine cyanobacteria in the genus Trichodesmium contribute a large fraction of the new nitrogen entering the oligotrophic oceans, but little is known about how they respond to shifts in g...
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...
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...
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
2014/5/9
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...
Sources of inorganic carbon for photosynthesis in a strain of Phaeodactylum tricornutum
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...
Bacteriochlorophyll a in the ocean: Is anoxygenic bacterial photosynthesis important?
Bacteriochlorophyll a in the ocean anoxygenic bacteria photosynthesis
2014/5/26
Some groups of marine bacteria within the α-proteobacteria are capable of anoxygenic photosynthesis in oxic environments. Their primary photosynthetic pigment is bacteriochlorophyll a (BacChl a). The ...
Latitudinal variation of the balance between plankton photosynthesis and respiration in the eastern Atlantic Ocean
Latitudinal variation plankton photosynthesis respiration eastern Atlantic Ocean
2014/6/10
A knowledge of the balance between plankton gross primary production (GPP) and community respiration (CR) in the open ocean is vital to the accurate determination of the global carbon cycle, yet the p...
Ultraviolet radiation sensitivity of photosynthesis in phytoplankton from an estuarine environment
Ultraviolet radiation sensitivity photosynthesis in phytoplankton estuarine environment
2014/6/9
We have studied temporal variation in the sensitivity of phytoplankton photosynthesis to inhibition by ultraviolet radiation (UV; 280-400 nm) using biological weighting functions (BWFs) that quantify ...
Enhancement of coupled nitrification-denitrification by benthic photosynthesis in shallow estuarine sediments
