Stoichiometric regulation of carbon and phosphorus in P-deficient Daphnia magna
Stoichiometric regulation carbon phosphorus P-deficient Daphnia magna
2014/4/21
Daphnia magna were fed phosphorus-sufficient (+P) and P-deficient (2P) green algae Chlamydomonas reinhardtii (carbon : phosphorus ratio of C: P = 90 and 930 in molar, respectively) for 5 d to produce ...
Scale-dependent carbon : nitrogen : phosphorus seston stoichiometry in marine and freshwaters
Scale-dependent carbon nitrogen phosphorus seston stoichiometry fresh waters
2014/4/21
The classical Redfield ratio of carbon106: nitrogen16: phosphorus1is a cornerstone of biogeochemistry. With the use of.2,000 observations of the chemistry of particulate matter from small and large la...
13 C dynamics in benthic algae: Effects of light, phosphorus, and biomass development
13 C dynamics benthic algae light phosphorus biomass
2014/4/18
We performed three experiments in indoor streams and one experiment in a natural stream to investigate the effects of growth factors on d13 C levels in benthic microalgae. In the indoor streams, algae...
Assessment of relative phosphorus limitation ofTrichodesmiumspp. in the North Pacific, North Atlantic, and the north coast of Australia
phosphorus limitation Trichodesmiumspp in the North Pacific North Atlantic the north coast of Australia
2014/4/18
Trichodesmiumspp. is a colonial diazotrophic cyanobacterium that occurs in the oligotrophic tropics and subtropics. Because of its ability to fix atmospheric N2, it is likely to be growth limited by P...

Changes in phosphorus biogeochemistry along an estuarine salinity gradient: The iron conveyer belt
Changes in phosphorus biogeochemistry estuarine salinity gradient The iron conveyer belt
2014/4/18
We used sequential extractions to quantify different forms of particulate phosphorus (PP) in sediments along the salinity gradient of the Patuxent River estuary. About 50-90% of the PP was phosphate b...
The influence of dissolved organic carbon on bacterial phosphorus uptake and bacteria-phytoplankton dynamics in two Minnesota lakes
The influence of dissolved organic carbon bacterial phosphorus uptake bacteria-phytoplankton dynamics two Minnesota lakes
2014/4/18
The balance of production in any ecosystem is dependent on the flow of limiting nutrients into either the autotrophic or heterotrophic components of the food web. To understand one of the important co...

penta-coordinate phosphorus intermediate square pyramid trigonal pyramid
2007/12/20
摘要 In this paper, based on known crystal structures of square pyramid (SP) and trigonal bipyramid (TBP) penta coordinated phosphorus compounds containing amino acid side chains, such as amino, carboxy...
By means of SEDEX, ASPILA and XRF, depth-dependent changes of different phosphorus forms in sediment cores from specific areas of the offshore Changjiang Estuary (Yangtze Estuary) in 1998 ...
Cd. The spatial distribution and chemical forms of heavy metals in tidal flat sediments were closely related to the distribution of pollution resources (outlet of sewage) and the local se...

Calcium Pigs Growth Biochemical Indices True Digestible Phosphorus
2016/4/26
Sixty healthy growing pigs (DurocLandraceYorkshire with an average BW of 21.4 kg) were used to determine the true digestible phosphorus (TDP) requirement of growing pigs on the basis o...
Natural inactivation of phosphorus by aluminum in preindustrial lake sediments
Natural inactivation phosphorus aluminum preindustrial lake sediments
2014/4/22
Noncalcareous phosphorus (P)-rich lake sediments typically release P associated with iron hydroxide [Fe(OH)3] during the development of hypolimnetic anoxia. High concentrations of aluminum hydroxide [...
