Desert algae shed light on desiccation tolerance in green plants（图）
Desert algae shed light desiccation tolerance green plants
2020/7/10
Deserts of the U.S. Southwest are hot and dry -- extreme habitats for most plants -- but, remarkably, microscopic green algae that live there are extraordinarily tolerant of dehydration.These tiny gre...
The asymmetry of the underwater horizontal light field and its implications for mirror-based camouflage in silvery pelagic fish
the underwater horizontal light field mirror-based camouflage silvery pelagic fish
2014/10/16
Many pelagic species, particularly teleost fish, have silvered lateral surfaces that are thought to primarily serve as a form of camouflage. The underlying argument is that the underwater light field ...
Aquatic algae can sense an unexpectedly wide range of color, allowing them to sense and adapt to changing light conditions in lakes and oceans. The study by researchers at UC Davis was published earli...
Effects of CO2 and their modulation by light in the life-cycle stages of the coccolithophore Emiliania huxleyi
Effects of CO2 their modulation light in the life-cycle stages coccolithophore Emiliania huxleyi
2014/4/4
The effects of ocean acidification on the life-cycle stages of the coccolithophore Emiliania huxleyi and their modulation by light were examined. Calcifying diploid and noncalcifying haploid cells (Ro...
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...
Temperature and photoperiod effects on phytoplankton growing under simulated mixed layer light fluctuations
Temperature and photoperiod effects phytoplankton growing simulated mixed layer light fluctuations
2014/4/4
We measured specific growth rates of Stephanodiscus minutulus, Nitzschia acicularis (diatoms), and Limnothrix redekei (cyanobacterium) under fluctuating and constant light in semi-continuous culture a...

Terrestrial organic matter and light penetration: Effects on bacterial and primary production in lakes
Terrestrial organic matter light penetration on bacterial primary production in lakes
2014/4/17
We investigated productivity at the basal trophic level in 15 unproductive lakes in a gradient ranging from clear-water to brown-water (humic) lakes in northern Sweden. Primary production and bacteria...
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 ...
How anthropogenic darkening of Lake Apopka induced benthic light limitation and forced the shift from macrophyte to phytoplankton dominance
Lake Apopka induced benthic light limitation forced the shift macrophyte to phytoplankton dominance
2014/4/17
Controversy exists about the historic shift of primary producer community structure (PPCS) in Lake Apopka,a shallow, 125-km2lake in central Florida, U.S.A. The controversial questions are: was a lake-...
Light effects on alewife–mysid interactions in Lake Ontario: A combined sensory physiology, behavioral, and spatial approach
Light effects on alewife–mysid interactions in Lake Ontario A combined sensory physiology behavioral spatial approach
2014/4/16
An understanding of the effect of light on predator–prey interactions in aquatic systems requires the integration of sensory physiology, behavioral ecology, and spatial distributions of predator and p...
A model of phytoplankton acclimation to iron–light colimitation
phytoplankton acclimation iron–light colimitation
2014/4/16
We developed and calibrated a dynamic model for cellular carbon, chlorophyll (Chl), and iron under iron–light
colimitation. The model allows growth rate and two other state variables (Fep

Effect of light and feeding on the fatty acid sterol composition of zooxanthellae host tissue isolated scleractinian coral Turbinaria reniformis
2014/4/21
The fatty acid and sterol compositions of zooxanthellae and animal fractions of the scleractinian coral Turbinaria reniformis were investigated under different light and feeding conditions, to study t...
