Stoichiometric imbalance in rates of nitrogen and phosphorus retention, storage, and recycling can perpetuate nitrogen deficiency in highly-productive reservoirs
nitrogen phosphorus retention storage
2014/11/28
We measured the nutrient stoichiometry of inputs, outputs, retention, storage, and recycling in three seasonally
nitrogen (N)-deficient reservoirs by incorporating watershed mass balances with measur...
Variations in Synechococcus cell quotas of phosphorus, sulfur, manganese, iron, nickel, and zinc within mesoscale eddies in the Sargasso Sea
phosphorus sulfur manganese iron
2014/4/16
The quotas of P, S, Mn, Fe, Ni, and Zn in individual Synechococcus cells collected from the surface and deep
chlorophyll maximum (DCM) layer of three mesoscale eddies in the Sargasso Sea were measure...
Abundance and variation of colloidal organic phosphorus in riverine, estuarine, and coastal waters in the northern Gulf of Mexico
colloidal organic phosphorus Abundance
2014/4/18
The abundance of colloidal organic phosphorus (COP) and colloidal inorganic phosphorus (CIP) was
quantitatively determined using an ultrafiltration permeation model for riverine, estuarine, and coast...
The effect of temperature on the coupling between phosphorus and growth in lacustrine bacterioplankton communities
phosphorus growth lacustrine bacterioplankton communities
2014/4/18
Phosphorus (P) routinely limits microbial growth in freshwater ecosystems. The growth rate hypothesis (GRH)
relates growth to biomass P content mechanistically through changes in ribosomal ribonuclei...
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...
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 [...
Degradation of organic phosphorus compounds in anoxic Baltic Sea sediments: A 31P nuclear magnetic resonance study
organic phosphorus compounds anoxic Baltic Sea sediments 31P nuclear magnetic resonance
2014/5/5
The composition and abundance of phosphorus extracted by NaOH-ethylenediaminetetraacetic acid from anoxic Northwest Baltic Sea sediment was characterized and quantified using solution 31P nuclear magn...
Fast growth and turnover of chironomid assemblages in response to stream phosphorus levels in a tropical lowland landscape
Fast growth turnover of chironomid assemblages
2014/4/23
We studied the response of a dominant primary consumer, larval Chironomidae (Diptera), to phosphorus (via a
microbial response) across eight detritus-based streams spanning a gradient in soluble reac...
Bacterial metabolism and growth efficiency in lakes: The importance of phosphorus availability
Bacterial metabolism growth effi ciency
2014/5/14
We investigated bacterial responses to variations in dissolved organic carbon (DOC) and nutrient availability by
a comparative analysis of bacterial metabolism in lakes ranging from oligotrophic to e...
Lake metabolism: Relationships with dissolved organic carbon and phosphorus
Lake metabolism dissolved organic carbon phosphorus
2014/5/20
Recent literature has suggested that for many lakes and rivers, the respiratory breakdown of organic matter (R) exceeds production of organic matter by photosynthesis (gross primary production [GPP]) ...
Iron-sulfur-phosphorus cycling in the sediments of a shallow coastal bay: Implications for sediment nutrient release and benthic macroalgal blooms
Iron-sulfur-phosphorus cycling in the sediments shallow coastal bay:sediment nutrient release benthic macroalgal blooms
2014/5/26
We conducted a study to determine the seasonal relationship between iron, sulfur, and phosphorus in the upper sediments and pore waters of a shallow intercoastal bay. From April 1999 to September 2000...
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...
