Effect of phosphorus limitation on elemental composition and stable carbon isotope fractionation in a marine diatom growing under different CO2 concentrations
Effect of phosphorus limitation elemental composition stable carbon isotope fractionation marine diatom growing different CO2 concentrations
2014/6/9
Blooms of the marine diatom Skeletonema costatum were initiated in closed-system batch cultures with P-deficient medium under two different initial concentrations of dissolved molecular CO2([CO2,aq]: ...
Seasonal variation of phosphorus limitation of bacterial growth in a small lake
Seasonal variation phosphorus limitation bacterial growth small lake
2014/5/30
A series of bioassay experiments were performed from spring to autumn in a small dimictic lake (Deep Pond, Massachusetts) to examine the potential for bacterial growth limitation by organic carbon (gl...
Phosphorus inactivation by aluminum in the water column and sediments: Lowering of in-lake phosphorus availability in an acidified watershed-lake ecosystem
Phosphorus inactivation aluminum in the water column sediments in-lake phosphorus availability acidified watershed-lake ecosystem
2014/6/17
Acid precipitation has been shown to reduce phosphorus (P) outputs from terrestrial sources. We present field evidence that the in-lake P cycle may also be disrupted in atmospherically acidified water...
Amount of phosphorus inactivated by alum treatments in Washington lakes

2014/6/17
The effectiveness of aluminum (Al) at retaining phosphate was investigated in alum-treated Washington lake sediments. Greater than background concentrations of Al and Al-bound phosphorus (Al-P) were d...
