Sedimentary phosphorus dynamics and the evolution of bottom-water hypoxia: A coupled benthic–pelagic model of a coastal system
Sedimentary phosphorus dynamics a coastal system
2014/4/8
The present study examines oxygen and phosphorus dynamics at a seasonally hypoxic site in the Arkona basin
of the Baltic Sea. A coupled benthic–pelagic reactive-transport model is used to describe th...
A discrepancy between predictions of saturating nutrient uptake models and nitrogen-to-phosphorus stoichiometry in the surface ocean
saturating nutrient uptake models nitrogen-to-phosphorus stoichiometry the surface ocean
2014/4/17
We derive a simple prediction about euphotic zone N : P stoichiometry from a large class of models that use saturating nutrient uptake functions to characterize N and P acquisition by phytoplankton. T...
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...
Stoichiometric regulation of carbon and phosphorus in P-deficient Daphnia magna
Stoichiometric regulation of carbon phosphorus P-deficient Daphnia magna
2014/4/18
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 ...
An empirical model describing the seasonal dynamics of phosphorus in 16 shallow eutrophic lakes after external loading reduction
p An empirical model describing phosphorus
2014/4/30
Based on monthly mass balances on 7–8 yr of data from 16 shallow (mean depth: 1–10 m), eutrophic, unstratified,
or only temporarily stratified Danish lakes, we developed a simple empirica...
Evidence for a delayed response of riverine phosphorus exports from increasing agricultural catchment pressures in the Lough Neagh catchment
riverine phosphorus exports riverine phosphorus exports
2014/4/30
Total phosphorus (TP) exports from the rivers draining into Lough Neagh increased between 1974 and 2000
despite lower TP inputs to the rivers from point sources. Over this period annual diffuse expor...
Growth rates of Antarctic krill, Euphausia superba: Comparison of the instantaneous growth rate method with nitrogen and phosphorus stoichiometry
Growth rates of Antarctic krill Euphausia superba Comparison of the instantaneous growth rate method with nitrogen phosphorus stoichiometry
2014/5/19
Zooplankton growth rates are hard to measure directly, and proxy measurements are desirable to encompass the variety of species and scales of interest. The growth rate hypothesis of stoichiometric the...
Phosphonates and particulate organic phosphorus cycling in an anoxic marine basin
Phosphonates particulate organic phosphorus
2014/5/19
Total particulate phosphorus (TPP), particulate inorganic P (PIP), and particulate organic P (POP) concentrations
were measured in a year-long series of sediment trap samples collected throughout the...
Carbon, nitrogen, and phosphorus budgets for a shallow subtropical coastal embayment (Moreton Bay, Australia)
Carbon nitrogen phosphorus shallow subtropical coastal embayment
2014/5/27
Average annual carbon, nitrogen, and phosphorus budgets were constructed for Moreton Bay. Primary production was the dominant source of carbon (by two orders of magnitude), N fixation was the dominant...
Amount of phosphorus inactivated by alum treatments in Washington lakes
phosphorus inactivation alum treatments 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...
