Functional quantum biology in photosynthesis and magnetoreception
Functional quantum biology photosynthesis and magnetoreception Biological Physics
2012/5/28
Is there a functional role for quantum mechanics or coherent quantum effects in biological processes? While this question is as old as quantum theory, only recently have measurements on biological sys...
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 ...
Phytoplankton distribution and photosynthesis dynamics in the Chubut River estuary (Patagonia, Argentina) throughout tidal cycles
Phytoplankton distribution photosynthesis dynamics the Chubut River estuary throughout tidal cycles
2014/4/16
The aim of this study was to determine the effects of the tidal dynamics and physical forcing on phytoplankton distribution and photosynthesis dynamics in the Chubut River estuary, Argentina. Physical...
Physicists in Canada and Australia have shown that nature exploits quantum mechanics to make photosynthesis more efficient. By probing light-harvesting proteins within algae using laser beams, the res...
An integrated model of soil-canopy spectral radiances, photosynthesis, fluorescence, temperature and energy balance
soil-canopy spectral radiances photosynthesis fluorescence temperature energy balance
2010/1/21
This paper presents the model SCOPE (Soil Canopy Observation, Photochemistry and Energy fluxes), which is a vertical (1-D) integrated radiative transfer and energy balance model. The model links visib...
While most school children understand that green plants photosynthesize, absorb carbon dioxide and produce oxygen, few people consider the profound global-scale effects that photosynthesis has had on ...

Photosynthesis boreal ground vegetation forest clear-cut
2010/1/21
Heather (Calluna vulgaris), rosebay willowherb (Epilobium angustifolium), wavy hair-grass (Deschampsia flexuosa) and raspberry (Rubus idaeus) are typical species at boreal clear-cut sites. In this stu...
