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...

Photoprotection mechanisms against ultraviolet radiation in Heterocapsa sp. (Dinophyceae) are influenced by nitrogen availability: Mycosporine-like amino acids vs. xanthophyll cycle
Heterocapsa sp Photoprotection mechanisms
2014/4/16
The photoprotective and acclimation capacity against ultraviolet radiation (UVR) was assessed for the
dinoflagellate Heterocapsa sp. We examined the effect of UVR and N availability on photosynthetic...
The effects of Cu and Fe availability on the growth and Cu:C ratios of marine diatoms
The effects of Cu and Fe availability on the growth and Cu:C ratios of marine diatoms
2014/4/21
We investigated the effects of copper (Cu) and iron (Fe) availability on the growth rates, cellular Cu content, and steady-state Cu uptake rates of eight species of centric diatoms (coastal and oceani...
Relative influence of nitrogen and phosphorous availability on phytoplankton physiology and productivity in the oligotrophic sub-tropical North Atlantic Ocean
nitrogen and phosphorous availability phytoplankton physiology and productivity the oligotrophic sub-tropical North Atlantic Ocean
2014/4/21
Nutrient addition bioassay experiments were performed in the low-nutrient, low-chlorophyll oligotrophic subtropical North Atlantic Ocean to investigate the influence of nitrogen (N), phosphorus (P), a...

Potential role of copper availability in nitrous oxide accumulation in a temperate lake
copper nitrous oxide accumulation temperate lake
2014/4/22
Denitrifying bacteria require copper for the synthesis of nitrous oxide reductase. In the absence of sufficient bioavailable Cu, nitrous oxide (N2O) may accumulate in natural waters during denitrifica...

2014/4/21
We investigate the hydraulic alteration and the effect on primary productivity of the Hugh Keenleyside Dam built at the outlet of the Arrow Lakes (British Columbia, Canada) in 1967. Three dam-induced ...
Phosphorus availability, phytoplankton community dynamics, and taxon-specific phosphorus status in the Gulf of Aqaba, Red Sea
Phosphorus availability, phytoplankton community dynamics, and taxon-specific phosphorus status in the Gulf of Aqaba, Red Sea
2014/4/23
The relationships among phytoplankton taxon-specific phosphorus-status, phytoplankton community composition, and nutrient levels were assessed over three seasons in the Gulf of Aqaba, Red Sea. During ...
Zinc availability and alkaline phosphatase activity in Emiliania huxleyi: Implications for Zn–P co-limitation in the ocean
Zinc availability alkaline phosphatase activity
2014/4/23
Zinc (Zn) serves as a cofactor in several extracellular phosphatases, which allow microorganisms to acquire
phosphorus from organic P compounds. In oligotrophic ocean water, where both phosphate and ...
Nutrient and light availability regulate the relative contribution of autotrophs and heterotrophs to respiration in freshwater pelagic ecosystems
Nutrient light availability regulate the relative contribution
2014/4/23
In this study, two main hypotheses were addressed. (1) Bacteria contribute proportionally less than autotrophs to
ecosystem respiration as trophic status increases. This hypothesis was examined in a ...
